Burning coal: There are SO2, nitrogen oxides and dust in the atmosphere.
Improper disposal of incineration slag will cause solid waste pollution. Andar2008 (contact TA in the station) wondered whether the pollution (dust, surface water pollution with precipitation) generated in the process of coal transportation and stacking was counted as the pollution in the process of use (contact TA in the station). This is very broad.
There are too many ways to use it, and the most common one is direct burning.
The main pollutants of combustion are nitrogen oxides and sulfur oxides, which mainly form acid rain;
Another thing that cannot be ignored is carbon oxides. Take carbon dioxide as an example, global warming; Another kind of carbon monoxide, which is toxic and harmful. ...
What's more, there are a lot of dust generated by coal combustion ............................................................................................................................................................... The amount is too large. Pollutants produced during the use of coal in Vaughan (ta in the contact station): 1, mining; 2. Transshipment and storage;
3. Combustion, distillation, etc. As a raw material;
4. The coal dust in the transportation process of wangkingpig (in-station contact TA) such as waste residue can use the dust suppressant guosq (in-station contact TA). There are harmful elements such as mercury and arsenic in coal, such as zmfeng (in-station contact with TA). Phenol water pollution in the production of blue carbon is serious. Syl 1204 (Contact TA in the station) Desulfurization is needed in the coal-burning process.
The generated fly ash can be used as cement products,
During the combustion process, the heavy metals mercury, arsenic and selenium will diffuse and settle into the surrounding environment with the gas, resulting in air pollution and dust pollution (PM 10, PM2.5).
The coal gangue produced in the mining process can be backfilled in the reclamation subsidence area, and the pollution of heavy metals and organic pollutants to soil, groundwater and growing plants should be considered.
