Sewage Treatment Project of Gansu Jiuquan Satellite Launch Center

The technical essence is to fill fillers into biological reaction tank; the oxygenated sewage immerses all fillers and flow through the fillers at a certain velocity. Fillers are full of biological membrane. Sewage has an extensive contact with biological membrane. Under the action of microbial metabolism on biological membrane, organic pollutants in sewage is removed and the sewage is purified. This project is used to dispose domestic waste water; the tank body is enamel-assembled, filled with fillers and set with aeration system, etc.
