Excuse me: Who are the main manufacturers of aluminum hydroxide? What environmental pollution and environmental protection measures will be produced in the production process? Thank you very much !

At present, there are many domestic manufacturers of aluminum hydroxide, mainly concentrated in Henan, Shanxi, Shandong, Guizhou and Guangxi, because these places are rich in aluminum mineral resources, unlike Chinalco, because the processes for producing aluminum oxide and aluminum hydroxide are the same, and aluminum oxide is an additional process after the production of aluminum hydroxide, that is, aluminum oxide, so more than 90% of aluminum hydroxide is used as raw materials for producing aluminum.

In the production process, there are several main aspects of environmental pollution and control.

1, because the production process belongs to chemical production, so the first thing is about chemical pollution, mainly alkali pollution, mainly from the aspects of running, running, dripping and leaking.

2, the prevention and control of flue gas dust, mainly SO2, dust particle content in the air, mainly through the desulfurization and dust removal device,

3, sewage treatment, in alumina production, as long as the production process is properly controlled, basically no sewage will be produced in the production process, all production sewage with alkali can be effectively utilized, and it is possible to achieve zero discharge.
