The requirements of environmental protection for coal scattering, and the conservation and environme

The main adverse effects are:

1) Greenhouse gas emissions, mainly carbon dioxide, nitrogen oxides (also have a strong greenhouse effect) (2) Dust method, the traditional boiler combustion dust removal facilities are not perfect, and the dust pollution environment is harmful to the human body, especially the particle size under 10 microns.

3) Acid gases, mainly sulfur dioxide and nitrogen oxides.

4) Generally, if the coal quality is good, cinder and fly ash can be used as raw materials for building materials, which is not considered pollution.

When coal is burned, it emits a lot of nitrogen in addition to carbon dioxide, which causes acid rain. Coal ash after combustion is also one of the pollutants.

Article 34 Implement the development strategy of giving priority to conservation, accelerate the comprehensive utilization of resources, reduce energy consumption in the process of coal processing and utilization, and improve the recovery rate and utilization efficiency of coal resources。

Article 35 Strengthen the management of energy conservation and energy efficiency, and establish and improve the system of rewards and punishments for energy conservation management, evaluation and assessment, energy conservation and emission reduction, and cleaner production in the coal industry。 Encourage coal enterprises to develop advanced and applicable energy-saving technologies, coal enterprises must be built in accordance with energy-saving design specifications and energy standards, must eliminate backward energy-consuming processes, equipment and products, and promote the use of energy-saving products that meet national energy efficiency standards and have been certified.

Article 36 In accordance with the principles of reduction, reuse and recycling, comprehensive development and utilization of coal-related resources and coal mine waste。 Encourage enterprises to use coal gangue, low calorific value coal power generation, heating, coal gangue production of building materials products, underground filling, reclamation and road construction, comprehensive use of mine water, the development of circular economy. Support the construction of long-distance pipelines for coalbed methane (coal mine gas), and encourage coalbed methane (coal mine gas) for civil use, power generation, and production of chemical products.

Article 37 The development and utilization of coal resources shall carry out environmental impact assessment in accordance with the law, and the "three simultaneous" system of project construction shall be strictly implemented for environmental protection facilities and main projects。 In accordance with the principle of who develops, who protects, who damages, who restores, who pollutes, who governs, who governs, who benefits, we will promote the comprehensive management of the environment in the mining area, and form a compensation mechanism for soil and water conservation, mine land reclamation and ecological environment restoration in the mining area that is synchronized with production.

Article 38 The pollutants produced in the process of coal mining, storage, loading and unloading must be discharged up to the standard to prevent secondary pollution。 Strengthen the extraction and utilization of coal mine gas and reduce emissions. Coal washing water should be closed-circuit circulation. Optimize the layout of the roadway and reduce the amount of gangue produced in the downhole.

Article 39 An evaluation system and evaluation index system for the environmental carrying capacity of mining area development shall be established. Strictly implement the system of environmental impact assessment, soil and water conservation, land reclamation and sewage discharge charges for coal mines. Coal mining is restricted in areas with a high risk of geological disasters, areas for the recharge of important groundwater resources, and areas with a fragile ecological environment, and coal mining is prohibited in nature reserves, important water source protection areas, and geological disaster risk areas.

Strengthen the comprehensive management of abandoned mines.

Article 40 The investigation, monitoring, forecasting and early warning of disasters that may be induced in the process of mine development shall be strengthened, and effective prevention and control measures shall be taken in a timely manner. Establish an information network system and formulate disaster prevention and mitigation plans.

Coal crushing: dust pollution, noise pollution.

Coal combustion: The atmosphere contains SO2 and NOx and dust.

Improper disposal of burned slag can lead to solid waste pollution. andar2008 (station contact ta) I don't know whether the pollution generated in the process of coal transportation and stacking (dust, surface water polluted with precipitation) is considered the pollution in the process of use.

There are too many ways to use it, and the most common is to burn it directly.

The main pollutants of combustion are nitrogen oxides, sulfur oxides, etc., which mainly form acid rain;

Another thing that cannot be ignored is carbon oxides, taking carbon dioxide as an example, global warming; Another carbon monoxide, toxic and harmful ......

There is also a very powerful dust produced by coal combustion, which is ...... grayIn addition, cinder is also relatively difficult to deal with, and the amount of pollutants produced during the use of vaughn coal is too large: 1. Mining; 2. Transshipment and storage;

3. Combustion, distillation, etc. as raw materials;

4. Coal dust in the transportation process of waste residue can be used with dust suppressant guosq (station contact ta) There are mercury and arsenic and other harmful elements in the coal, and the phenol water in the production process of blue charcoal, heavy pollution ah syl1204 (station contact ta) coal combustion process to desulfurize, the fly ash produced can be used as cement products, The heavy metals contained in the combustion process, mercury, arsenic and selenium will settle into the surrounding environment with gas diffusion, causing air pollution, dust pollution (PM10, the coal gangue produced in the mining process can be backfilled and reclaimed subsidence area, and the pollution of heavy metals and organic pollutants to soil, groundwater, growing plants, etc. should be considered

a. The use of solar energy will reduce the burning of coal, oil and other resources, which is conducive to reducing the emission of air pollutants, so it is in line with the topic;

b. Mining small coal kilns, burning coal will pollute the atmosphere, so it does not meet the topic;

c. Burning straw will pollute the atmosphere, so it does not meet the topic;

d. The construction of biogas digesters cannot reduce the emission of air pollutants in rural areas of our country, so it does not meet the meaning of the topic
