Investigation report on classified treatment of domestic waste

Investigation report on classified treatment of domestic waste

When we need to know a situation or an event, we need to analyze it from coarse to fine, and the results of the investigation are usually presented in the investigation report. How to write an investigation report in a logical way? The following is a survey report on the classified treatment of domestic waste, which I have carefully compiled. It is for reference only and I hope it will help you.

Investigation report on classified treatment of domestic waste 1 1. Ask questions:

With the development of social economy, environmental pollution is becoming more and more serious, and urban garbage can be seen everywhere. According to relevant data, in the past 10 years, the urban garbage in China increased at an average annual rate. Two thirds of the 400 large and medium-sized cities in China are surrounded by garbage. China has accumulated 6 billion tons of garbage over the years, occupying about 500 million square meters of land. At present, China is still producing hundreds of millions of tons of new garbage every year. How are these rubbish produced and how are they treated? These problems aroused our great research interest.

First, the current situation investigation:

In the morning, garbage can be seen everywhere on both sides of the street. Some are wrapped in plastic bags, some are thrown on the ground at will, and some are put in trash cans.

Passing by the hospital, I saw some expired drugs, discarded mercury thermometers, some medicine bottles and infusion sets abandoned in the corner of the hospital. These rubbish give off a pungent smell, which makes me afraid to go near.

In the corner of the factory building, abandoned batteries, old machines, circuit boards, broken glass and broken wood boards piled up into mountains. The battery was damaged and the liquid in it leaked out. Waste batteries are called "mini killers". We can imagine how much harm these waste batteries will do to the land after they penetrate into the soil.

In the vegetable market, discarded fish and vegetables are piled up on the road at will, and flies are buzzing. This surprised me. Are all the foods you can't buy thrown away at will?

A sanitation worker told me that these mountains of garbage were sent to a certain place for landfill or incineration.

Third, the hazards of garbage:

Disposing of garbage at will is potentially harmful. How much land does it take to turn such a large amount of garbage into a landfill? How many toxic gases will be produced during incineration, which will endanger people's health? We constantly turn the limited earth resources into garbage, bury or burn them. Where will our future generations find the energy they need in a long time?

Four, garbage disposal classification:

Are we helpless about the pollution of garbage? No, according to our investigation, garbage can be generally divided into four categories: recyclable garbage, kitchen waste, harmful waste and other garbage.

Recyclable garbage is directly sent to relevant factories for reprocessing and waste utilization. For example: 1 ton waste paper can be recycled into 800 kilograms of good paper; Rare metals such as zinc, copper and manganese dioxide can be extracted from recycled batteries; The recycled waste plastics can be recycled into fuel.

Kitchen waste, such as leftovers, lettuce, eggshell skin, cabbage leaves, etc. , can be piled up, let waste fiber and organic matter decay, into fertilizer, improve the soil.

In harmful waste, such as waste fluorescent tubes, expired drugs, etc., can be burned together, so as to minimize the harm of garbage.

Other garbage, such as ceramics and dregs, is difficult to recycle and has no harm to the environment. It can be effectively landfilled and reduce the pollution to groundwater, soil and air.

Five, our thinking:

Relevant statistics show that the value of waste that can be used but not used in China reaches 25 billion yuan every year, and about 3 million tons of scrap steel and 6 million tons of waste paper are not recycled. The recovery rate of waste plastics is less than 3%, and the recovery rate of rubber is 3 1%. Only more than 6 billion waste dry batteries contain more than 70,000 tons of zinc and 654.38+10,000 tons of manganese dioxide every year. Garbage sorting and recycling is of great value;

Waste paper:

Recycling waste paper 1 ton can regenerate 800 kilograms of good paper, save 0/7 trees/kloc-0, save 3 cubic meters of landfill space, save 240 kilograms of soda ash, reduce papermaking pollution emissions by 75%, and save papermaking energy consumption. Each paper can be recycled at least twice.

Waste plastics:

Plastics come from oil, which is a non-renewable resource on the earth. Recycling waste plastics is to save oil. All waste plastics, waste lunch boxes, food bags, woven bags, soft packaging boxes, etc. It can be recycled into fuel by reducing waste plastics into gasoline and diesel oil; 1 ton of waste plastics can produce 10 liter of unleaded gasoline or diesel oil.

Waste glass:

Recycling waste glass can not only save natural resources, but also reduce energy consumption by about 32%, air pollution by 20% and water pollution by 50%. Recycling 1 ton of waste glass saves 20% of the cost compared with using new raw materials. The benefits of recycling one ton of waste glass to the environment and resources are: 720kg of quartz sand, 250kg of soda ash, 60kg of feldspar powder, 0/0t of coal/kloc and 400 kwh of electricity can be saved.

Discarded aluminum cans:

After the waste cans are dissolved, they can be recycled 100% for countless times to make new cans, and can also be made into parts of cars, planes and even furniture. Recycling aluminum cans can save 95% of the energy needed for new aluminum cans and reduce 95% of air pollution. Discarding an aluminum can is equivalent to wasting half of the oil in the aluminum can.

Organic matter:

More than 40% of the garbage we still leave home every day is kitchen waste such as peels, eggshells, vegetable leaves and leftovers, which can be treated as organic fertilizer or feed by composting and fermentation.

Waste battery:

Mercury and cadmium contained in waste batteries are toxic heavy metals with high pollution, but rare metals such as zinc, copper and manganese dioxide can be extracted from recycled batteries.

Intransitive verbs Our suggestions:

1, let people understand the importance of garbage classification through publicity;

2. Set up sorting bins in residential areas, vegetable markets, hospitals, factories and other places to facilitate sanitation workers to sort all kinds of garbage.

Garbage is a public hazard, but as long as we use the method of garbage classification to deal with it, we can completely turn garbage from enemies into friends.

3. Investigation report on ceramics

Today, we went to Zhejiang Museum to do a survey on ceramics. We are divided into two groups, A and B. Group A investigates pottery in the exhibition hall on the first floor and Group B investigates porcelain on the second floor. I joined group a.

After reading the introduction and listening to the explanation, I know that pottery and porcelain are not the same thing. Pottery appeared before porcelain. Pottery is a container made of small particles of soil. In ancient times, pottery was mainly used for sacrifice and burial.

Porcelain appeared in the Eastern Han Dynasty, and the surface of pottery was coated with a smooth glaze. According to the different glaze colors, there are many kinds of porcelain, such as celadon and white porcelain ... The famous celadon, because of the iron in the glaze, appears jasper-like cyan. "

In ancient times, pottery and porcelain were used for sacrifice, inheritance and other activities. In modern times, ceramics have become daily necessities, which can help people to wash rice and serve rice, and become an indispensable item in family life.

Ceramics are indispensable in ancient and modern times, and they are the crystallization of the wisdom of the ancient working people in China.

Investigation report on classified treatment of domestic waste 2 I. Overview

(1) investigation time:

(II) Investigation Location: xx Village, Changsha City

(3) Investigation method: interview method and observation method are adopted.

(IV) Survey object: garbage disposal in Daming Village, Laodaohe Town, Kaifu District, Shashi.

(V) Survey background: Now life is getting better and better, people's living standards are constantly improving, and all kinds of consumption are increasing, which has brought about economic development. It also brought more garbage. Garbage has increased. The air is getting worse and worse, the sanitation is getting worse and worse, and all kinds of garbage are constantly appearing and increasing. There are fewer and fewer places to bury garbage. If this continues, are we going to live in a garbage dump? I think this is worth thinking about, so I launched an investigation. I chose a village in Kaifu District, Changsha City, and investigated the garbage piling, removal and disposal there.

Second, the result

The result is still unsatisfactory, because at this rate, I can't see the future, because the generation of garbage and the disposal of garbage are synchronous! Because in my opinion, the speed of garbage disposal should be faster than that of garbage generation, which shows that garbage is decreasing day by day, instead of processing one part and generating another! Some people may think that garbage disposal is no big deal. Then you are wrong. On the importance of garbage disposal from the harm of garbage. Garbage is inevitable in people's lives. If it is not treated in time, a large amount of garbage will be piled up at will, occupying land for a long time, producing stench, causing serious pollution to the atmosphere, water body and soil, leading to the breeding of flies, insects and rodents, threatening the health of residents. Therefore, garbage is a big burden for cities. Garbage disposal is not easy, which can be summarized as follows: First, from the average composition of garbage, most residents' living fuel is coal, and coal ash accounts for a large part of the total garbage. Organic garbage in markets and kitchens, fallen leaves and dust in streets and courtyards are also mixed with a certain amount of impurities such as glass, plastics and bad metals, which are difficult to burn and destroy. Secondly, fertilizing with this garbage will spoil the land. Third, in the past, garbage was buried underground, but now it is found that burying garbage underground will destroy groundwater, and landfills will not be of great use. What's more, all the depressions that can be buried in the suburbs and urban areas are almost used up, and it is urgent to find a way out for garbage. In addition, although some regulations on environmental sanitation have been formulated, they have little effect because they cannot be strictly implemented. Littering everywhere exists, and the amount of garbage is still increasing. How to deal with garbage is really a top priority.

Third, there are problems.

(1) The amount of daily garbage is increasing.

(2) Sanitary landfill is still the main way of garbage disposal, which takes up a lot of land resources. Today, when land resources are very precious, it will play an inestimable role if the growth of landfills is effectively reduced and used for economic development.

Fourth, the coping methods

(1) Reduce land occupation: Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 50%.

(2) Reduce environmental pollution: Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human beings; Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can reduce the harm.

(3) Turning waste into treasure: China uses 4 billion plastic snack boxes and 500-700 million instant noodle bowls every year, and waste plastic accounts for 4-7% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%-40% of the production waste can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.

Verb (abbreviation of verb) Specific classification of garbage

(1) Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth. Waste paper: mainly includes newspapers, periodicals, books, various wrapping papers, office paper, advertising paper, cartons and so on. However, it should be noted that paper towels and toilet paper are too water soluble to be recycled. Plastics: mainly include all kinds of plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skins, etc. Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects: mainly including cans, cans, etc. Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc. Comprehensive treatment and recycling can reduce pollution and save resources. If every 1 ton of waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and pollution is reduced by 74% compared with the same output; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.

(2) Kitchen waste, including food waste such as leftovers, bones, roots, leaves and peels, can be composted in situ by biotechnology, and 0.3 tons of organic fertilizer can be produced per ton.

(3) Hazardous wastes, including waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. , need special safety treatment.

(4) Other wastes, including bricks and tiles, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle, can effectively reduce the pollution of groundwater, surface water, soil and air through sanitary landfill.

Conclusion of intransitive verbs

Environmental sanitation depends on everyone, and garbage disposal depends on everyone's cooperation. If everyone could stop littering and throw less rubbish, I don't think there would be such a difficult situation of garbage disposal now. At present, this possibility is not difficult to realize. There is a saying: one person's garbage is another person's treasure! You can imagine. Garbage is not completely useless!

Investigation report on classified treatment of domestic garbage 3 With the growth of population, there are more and more domestic garbage. Many countries and regions burn garbage to alleviate the situation of garbage piling up into mountains. Even landfill some garbage! These improper treatment methods not only pollute rivers, but also endanger human health. In order to solve this problem, people adopt the method of garbage classification. The following is my investigation.

1, domestic waste classification.

In order to make garbage classification a habit in people's lives, I conducted a survey on garbage classification in the community. Inquire about the implementation of domestic waste classification and the problems existing in the implementation.

Investigation time: 20xx from February 2 to February 4.

Survey location: Unit 3, Building 5, North District, Binhe Garden Community.

Survey content: the classification and importance of garbage by residents in this unit.

Form: taking photos and interviewing residents.

Survey results: After accurate calculation, it is found that 65,438+00% of the residents pay special attention to the classification of domestic waste and carefully sort it out. 40% people think it doesn't matter. It's always kitchen garbage and toilet garbage. 20% people think it's none of his business, so let the garbage dump clean up. 30% people want to organize by heart, but they don't know how to organize.

2. Garbage classification.

As the name implies, garbage classification is to classify different kinds of garbage separately. According to the composition and output of garbage, combined with the resource utilization and treatment methods of local garbage, it is classified.

There are four kinds of garbage, namely harmful waste, other garbage, recyclables and kitchen garbage. Recyclable garbage generally includes waste paper, scrap metal, plastic bottles, etc., which can be recycled; Harmful waste is a waste battery and mobile phone, which is harmful to the environment and human body; Kitchen garbage is some fruits and vegetables left over from cooking and eating. Other rubbish is rubbish that does not belong to the above three kinds, such as cigarettes and clothes.

3, classified publicity and expansion

In the community, you can see the propaganda of garbage classification in the elevator. Red paper with obvious purpose is printed with black characters and hung next to the elevator button to remind people. Every owner also received a short message from the property to remind people of the importance of garbage sorting.

4. Household garbage classification status:

According to my observation these days, the situation of household garbage classification is not very ideal. There is also a lot of rubbish in the trash can that doesn't belong to it. When the trash can is full or even dissatisfied, we can also see all kinds of garbage scattered outside the trash can, and sometimes the smell will spread, which makes people feel uncomfortable after breathing. In terms of sorting, we need to improve.

5. My thoughts and ideas.

I think garbage sorting is something that each of us should do, and it is also our responsibility. Human beings are making progress, so our home should not be messy, but neat and beautiful. To take a step back, because of this large amount of garbage, many freshwater rivers on the earth are polluted. These garbage that are not treated in time will slowly breed bacteria, and people and animals may be infected with diseases. And garbage sorting can effectively help us deal with garbage, and it is not that difficult. If most people pay attention to it, it may reduce some harm to us and the earth.

6, experts remind.

There is only one earth for human beings, and its resources are limited. How to realize the infinite development of mankind with limited earth resources? Then we must make the earth's resources renewable forever. There is no doubt that the classification and recovery of original garbage should be a crucial link in the recycling cycle.

7. Real events.

Of the 57 people who died in the area within 1.2 km of Ibaraki waste incineration plant in Japan, 24 people died of cancer, accounting for 42. 1%. Of the 167 people who died away from 1.2km, 34 died of cancer, accounting for 20.4%.

8. Maintain the environment, starting with me.

0 1, the source of easy and sustainable resources.

02, everyone has a classified heart, and garbage can also turn stone into gold.

03. Control "white pollution" and build a green home.

04, a radish is a pit, don't let the garbage jump into the wrong pit.

9. My suggestion.

Pay attention to everything from the doll. I suggest that children can be taught the truth and reason of garbage classification when they are about three years old. Even now, many young people can't tell what kind of rubbish they belong to. At school, they can have a special garbage sorting class for one semester, telling students the nature of most garbage in garbage sorting, telling them the benefits of garbage sorting and why they should do it. At the same time, adults should also have a handsome role, and the local government should actively respond to people's garbage classification. You can also let some representative and authoritative public figures do the propaganda of garbage classification, and the residents' response may be stronger.

Finally, I hope more people in our country will unite and do their bit for the future of our country and even the future of the earth.

10, feelings.

Garbage is the main factor affecting life. We must pay attention to garbage sorting to keep healthy better. Come on!

Investigation report on classified treatment of domestic waste. First of all, the question is raised:

We live in this world. No matter what we do, we produce garbage every day. So how to deal with these rubbish is correct, and how can we do it without hurting human beings?

Second, the purpose of the investigation

1, understand the correct method of garbage disposal.

2. Enhance environmental awareness.

3. Improve your investigation ability.

Third, the method of investigation.

1, consult books

Step 2 interview people around you

3. Online inquiry

4. Go deep into reality and investigate in person.

Fourth, the content of the investigation

1, the phenomenon of littering on the road

2. Garbage cans and cleaning in streets and communities.

3. Classification of domestic waste.

Verb (the abbreviation of verb) investigation preparation:

Before the investigation, we investigated the harm of garbage and the information of online garbage classification. Data show that harmful substances in garbage will pollute soil, air and water, which not only wastes resources, but also seriously damages the ecological environment. After a large amount of garbage is piled up, biological decomposition will occur in the garbage dump, and methane gas will be produced during the decomposition process, and methane gas will easily explode when it gathers to a certain extent; Garbage is rich in protein, lipids and sugars. At room temperature, NH3, H2S and harmful hydrocarbon gases are produced in the process of decomposing organic matter by microorganisms, which have obvious stench and toxicity and directly harm human body. If discarded electronic and electrical products are randomly discarded and scattered into the environment, it will do harm to human health and destroy the ecological environment. For example, harmful heavy metal elements contained in e-waste will harm the water environment and the health of surrounding residents for a long time once they enter the water body. In addition, the freon contained in refrigerants and heat preservation foaming agents of refrigerators and air conditioners, once leaked, will destroy the atmospheric environment, and then bring harm to human health! If human beings don't take measures to properly dispose of garbage, eventually human beings will be retaliated and can't find the pure land for survival.

Garbage classification table:

Recyclable garbage: paper, metal, plastic, glass, etc.

Kitchen waste: food waste such as leftovers, bones, roots and leaves.

Hazardous wastes: waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc.

Other garbage: bricks, tiles, ceramics, muck, toilet waste paper and other wastes that are difficult to recycle.

Sixth, the investigation process.

A team investigated residential areas and vegetable markets.

Survey process and feedback:

1, the phenomenon of littering on the road

We took a trash can near Nanyuan Community as the observation point. In the morning, the trash can was just cleaned and empty.

Young man: Throw away the banana peel when it is 5 meters away from the trash can.

Fashion woman: Holding her nose, like running away, she threw away the garbage bag and left.

Middle-aged man: He passed the trash can, came over and threw the cans into the nearby river.

Elementary school students: properly throw the leftover food packaging bags into the trash can.

Old woman: Carefully bypass the trash can and throw the garbage bag into the trash can. ...

Findings:

An hour later, only three of the 13 people who took out the garbage threw it into the trash can. Garbage is piled around the trash can, and flies are flying on it.

2. Garbage cans and cleaning conditions in streets and residential areas.

From the vegetable market to the experimental primary school: there are 10 unclassified trash cans along the way, and there is little garbage in the trash cans. At that time, when street vendors were collecting stalls, there were many broken leaves and fruit branches and leaves on the ground, which were very dirty. But after 1 hour, it has been cleaned by the cleaner.

Yiyuan Community: There are large and small trash cans and garbage rooms in the community. The opening of the small trash can is only about 10 cm high, and the slightly larger garbage bag can't be put in. Some people put rubbish in the trash can for convenience. The situation of the big trash can is better. The garbage in the garbage room is the responsibility of the cleaner, and there is no littering.

Lan Song Community: Garbage cans in the community can be recycled and non-recyclable, and the road surface is clean. Although the outside of the dustbin is clean, there is no distinction between recyclable and non-recyclable inside, but littering. Recyclable garbage such as paper and cans is mistakenly thrown into the non-recyclable category. Toxic wastes such as waste batteries, waste fluorescent tubes, expired drugs and waste water silver thermometers are mixed into recyclable categories.

The second group surveyed residents and students.

Survey process and feedback:

1, 10 households were investigated in the community.

For garbage classification, only 2 households in 10 know and are willing to classify. And five households know and are willing to classify, but sometimes the lid of the trash can is small and there is a lot of garbage, which is too troublesome. Two families know but don't want to classify, because it's too much trouble to do. 1 users don't even know the classification.

2. Investigate the garbage disposal methods of 20 students.

5% of the garbage is classified and bagged, 1% burned, 1% buried, 90% thrown into the dustbin, and 3% thrown casually.

Investigation results: The correct method of garbage disposal: recycle the available garbage, classify all kinds of recycled garbage, and then transport these garbage to agents or factories for further processing to make other items. This method is effective and economical, and the garbage will not be polluted. Organic waste is composted at high temperature, burned and buried in hazardous waste.

Seven, thinking and suggestions

We sorted out the survey results, expressed our opinions and summarized the following suggestions:

1. Setting up classified garbage bins requires an overall planning and system configuration, not surface engineering, because it is a matter of living habits and quality of life for everyone to classify and throw garbage;

2. Mark eye-catching patterns or text descriptions on the sorting trash can, so that when you throw garbage, you can easily and accurately sort the garbage;

3. Let everyone experience the practical benefits brought by garbage sorting and throwing. For example, in a community with good garbage classification, it is not only a matter of saving several tons of water fees, but also an honor and a socially recognized public welfare act.

4. Buy food with your own basket and refuse to use disposable plastic bags. Promote the use of environmentally friendly plastic bags, improve technology, reduce costs, and improve utilization value, such as advertising on packaging bags;

5. Use sterilized chopsticks when eating, and refuse to use disposable chopsticks. We advocate the use of handkerchiefs after meals and refuse to use napkins;

6. Call on people to eat as much as possible when cooking, especially in restaurants, to avoid waste and solve the problem of swill;

7. About littering, it is easy to do but forgotten by people. If you impose heavy penalties like Singapore, you should also receive miraculous effects.

I read a news in the newspaper before: On the second day of the Golden Week of November, more than 80 Korean tourists, including more than 30 children, collectively picked up garbage in Nanshan Scenic Area of Urumqi. These guests from afar spontaneously organized themselves to clean up the garbage. In just 20 minutes, nearly 1 km of garbage in Fiona Fang was cleaned up. Korean tourists can continue to play with peace of mind after driving five cartons full of garbage to the garbage station.

Although the actions of Korean tourists are small, they are thought-provoking. The earth belongs to everyone, and green civilization is formed under the protection of people. Only by making garbage "belong to everyone" can a green civilization be formed; Green civilization is formed by keeping bad habits away from the human body ... May we really find the green civilization in our hearts as soon as possible.
