This project is the water reuse zero discharge treatment of 800 thousand tons per year of electrolytic aluminum project in Xinjiang.

The comprehensive wastewater treatment capacity is 1000m3/d, desulfurization workshop wastewater treatment capacity is 360m3/d.

The raw water of the comprehensive wastewater treatment system mainly comes from the biochemical treatment of domestic sewage, boiler concentrated water, pollutants of water are high hardness, high suspended matter.
