Investigation report on garbage classification

Investigation report on garbage classification

In order to understand a certain situation and an event, we need to carry out the investigation with innovative spirit and write the laws and experiences we have explored into the investigation report. How to write an investigation report to avoid false emptiness? The following is a survey report on street garbage classification collected by me for reference only. Let's have a look.

Verb (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.

Natural degradation schedule of garbage

Paper for 3-4 months; Cigarette butts 1-5 years; Orange peel for 2 years; Tin can 2019; Nylon fabric for 30-40 years; Wool fabric 1-5 years.

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 and tiles, muck, toilet waste paper and other wastes that are difficult to recycle except the above garbage.

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: Just five meters away from the trash can, throw away the banana peel.

A woman dressed in fashion: holding her nose, like fleeing, she threw away the garbage bag and left.

Middle-aged man: He passed by the trash can and came to throw the cans into the nearby river.

Pupils: 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 in streets and communities.

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.

Investigation report on garbage classification 2 With the rapid development of science and technology, the process of urban modernization is accelerated, and our life has become rich and colorful. However, along with these advances, it is not only the convenience of people's lives, but also the continuous deterioration of urban living environment. Environmental problem is one of the main social problems today, and the classified treatment of garbage is particularly important, which is directly related to the degree of environmental damage caused by domestic garbage. Therefore, sorting garbage well will be an important measure to alleviate environmental problems. In order to deal with domestic waste better and create a beautiful and comfortable living environment, several friends and I conducted some research on the domestic waste treatment in my city, and talked about my understanding and suggestions in combination with the reality.

First, the classification of garbage.

Garbage is mainly divided into: construction garbage, medical garbage, industrial garbage, sewage sludge and domestic garbage. Construction waste can be recycled by the construction unit; Medical waste is disposed of by hospitals and other health units; The treatment of industrial waste is mainly the responsibility of enterprises; Wastewater sludge is also treated by wastewater treatment plant. The production of these wastes is relatively concentrated, which is convenient for classified treatment.

Second, the benefits of garbage sorting

Classified garbage collection can reduce the amount and equipment of garbage treatment, reduce the treatment cost and reduce the consumption of land resources, which has social, economic and ecological benefits. The advantages of garbage sorting treatment are as follows:

1, reducing land occupation. Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification can reduce the amount of garbage by more than 60% by removing recyclable and non-degradable substances.

2. Reduce environmental pollution. Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body; Waste plastics in soil will lead to crop yield reduction; Waste plastic is eaten by animals by mistake, which will lead to animal death. Analysis Report on Market Prospect and Investment Planning of Domestic Waste Treatment Industry in China China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls and billions of disposable chopsticks every year, accounting for 8%- 15% of domestic waste. 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. 1 ton cans can be melted to form 1 ton good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%~40% of 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.

Third, the characteristics of domestic waste

Compared with other garbage, the situation of domestic garbage is much more complicated, mainly in the following aspects:

1, the source is extensive and scattered, diverse and complex. The so-called domestic garbage, as the name implies, will produce domestic garbage as long as it is where people live. We live in different places, even in the same city, in the same corner of the city. It takes manpower and material resources to gather. Moreover, the life of modern people is complex and diverse, so there are all kinds of domestic garbage, such as plastic bags, paper towels, chewing gum, waste electronic products and so on. Involving inorganic, organic, degradable, difficult to degrade, toxic and harmful. In this way, it is no exaggeration to say that the sources of domestic waste are extensive, scattered and complicated.

2. People generally lack the common sense and habit of garbage sorting. The vague knowledge of garbage classification leads to people's poor understanding of the concept of garbage classification. For example, the classification of garbage at present is mainly divided into recyclable and non-recyclable. This classification is not clear enough. People only know some common recyclable garbage, but they don't know the unusual recyclable garbage. In my opinion, the classification of non-recyclable garbage is too general. Domestic garbage, such as plastic bags and melon seeds, can be said to be non-recyclable, but plastic bags are non-degradable, while melon seeds are degradable, and their treatment methods are different.

3. Some domestic wastes are improperly treated and lack of professional garbage disposal technology. This situation began to change from small and medium-sized cities. Due to the small scale of the city, there is no corresponding garbage disposal station. It is not uncommon for a large amount of domestic garbage to be piled up in the suburbs and burned on the spot. This leads to the re-pollution of domestic garbage, and the burning dust and toxic and harmful gases pollute the atmosphere, which directly affects the quality of life of residents.

4. The hardware facilities in residential areas are uneven, which greatly hinders the front end of garbage sorting. Some garbage bins in the community are classified garbage bins, and some are unclassified garbage bins. The front end that leads to garbage is not well handled, the garbage is not classified at all, and there is no way to deal with it in the later stage.

5. The intermediate treatment of domestic waste classification is unreasonable. The middle stage of garbage sorting treatment refers to the further classification of garbage in sanitation garbage transfer station, which will be a key step to determine the back-end treatment. The garbage transfer station further classifies the garbage, and then carries out different treatments on the classified garbage. If sanitation workers don't pay enough attention to garbage classification and mix the garbage that residents have classified, it would be a big mistake. The reason for this is that there are indeed many sanitation workers doing this.

6. The terminal treatment of domestic garbage is not scientific enough. At present, there are many methods to deal with domestic garbage, some of which are reasonable and some are unreasonable. For example, burning garbage in the open air is unscientific, which not only wastes the potential utilization value of garbage, but also pollutes the environment, which is really wrong. Similarly, the landfill method is not very reasonable. It is thankless to waste labor to landfill garbage. On the contrary, it is the best choice if domestic garbage is used for power generation or reused in different categories.

Fourthly, the method of classified treatment of domestic waste.

At present, domestic garbage in China can be generally divided into four categories: recyclable garbage, kitchen garbage, harmful waste and other garbage. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration for power generation, composting and resource reuse.

Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth. Waste paper mainly includes newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cartons, etc., but 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 materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skins and so on.

Glass mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects mainly include cans, cans and so on. Cloth mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc.

Kitchen waste includes food waste such as leftovers, bones, roots, leaves and peels. After in-situ composting by biotechnology, about 0.3 tons of organic fertilizer can be produced per ton.

Hazardous wastes include waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc., which need special treatment.

Other wastes include brick and tile ceramics, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle except the above-mentioned types of garbage. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

Verb (abbreviation for verb) Important measures in some cities

The key to realize waste reduction and recycling is front-end classification. If the government budget can take into account the "front-end" demand, provide special funds to encourage citizens to participate in waste sorting, subsidize volunteers who guide sorting and cleaning workers who engage in "secondary sorting", and increase investment in sanitation packaging and distribution equipment, then the implementation effect of waste sorting will be more obvious.
