The earth's environmental protection materials include so much content.

1. Environmental protection information can be interpreted as information about environmental protection, including daily environmental protection knowledge and environmental protection professional information.

2. The knowledge of environmental protection generally includes some environmental protection terms and daily slogans, such as what is white pollution and saving water.

3. According to professional technology, environmental protection professional data can be divided into ecological environmental protection data, wastewater treatment data, waste gas treatment data, noise treatment data, solid waste treatment data, environmental impact assessment data and cleaner production data; According to the needs of users, it can be divided into environmental protection laws and regulations, environmental protection standards and specifications, and environmental protection examination materials; Information can be divided into environmental protection equipment manufacturer information, environmental protection exhibition exchange information, environmental protection recruitment and job search information, environmental protection bidding information, etc.

4. Eco-environmental protection. On April 22, 197, Dennis Hayes, a student of Harvard University in the United States, initiated and organized environmental protection activities, which received enthusiastic response from environmental protection organizations. About 2 million people from all over the United States participated in this massive procession and assembly, aiming at arousing people's awareness of environmental protection and prompting the US government to take some measures to control environmental pollution. Later, this activity was approved by the United Nations. So far, April 22nd every year has been designated as "Earth Day".

5. wastewater treatment methods are to treat waste water by physical, chemical and biological methods, so as to purify waste water, reduce pollution, recover and reuse waste water and make full use of water resources.

6. Waste gas treatment is also called waste gas purification. Waste gas treatment refers to the pretreatment of waste gas produced in industrial places and factory workshops before external discharge, so as to meet the national standards for external discharge of waste gas. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air disinfection and purification.

7. Noise treatment includes sound insulation and silencing. Sound insulation refers to a measure that when sound waves propagate in the air, all kinds of energy-absorbing substances are generally used to consume the energy of sound waves, so that sound energy can not pass directly in the propagation path. This measure is called sound insulation.

8, silencing by some processing means or tool materials, to eliminate the specified sound, or the sound generated when the article is used.

9. solid waste disposal. solid waste disposal usually refers to the process of transforming solid waste into transportation, storage, utilization or disposal by physical, chemical, biological, physicochemical and biochemical methods. the goal of solid waste disposal is harmlessness, reduction and resource utilization.

1, Environmental Impact Assessment, environmental impact assessment for short, English abbreviation EIA, that is, environmental impact assessment, refers to the analysis, prediction and evaluation of the possible environmental impact after the implementation of planning and construction projects, put forward countermeasures and measures to prevent or mitigate adverse environmental impacts, and follow-up monitoring methods and systems. Generally speaking, it is to analyze the possible impact on the environment after the project is completed and put into production, and put forward pollution prevention countermeasures and measures.

11. Cleaner production is a kind of production mode in ecological industry and ecological engineering. In 1997, the United Nations Environment Programme redefined it as: the continuous application of integrated and preventive environmental strategies in processes, products and services to increase ecological benefits and reduce harm and risks to human beings and the environment.
