Shijiazhuang Qiaoxi wastewater treatment plant treatment process

Shijiazhuang Qiaoxi Wastewater Treatment Plant adopts gradual reduction of aeration common activated sludge method (with multi-point water intake).

(Parallel 2, single pool folding 5 corridor, each corridor: length × width = 86m × 8m, the effective depth of 5.2m, the aerator decreasing arrangement, each pool 5991)

Sewage in the aeration tank residence time of 2 hours. The main function is to remove a large number of colloidal and dissolved organic pollutants in the sewage, such as BOD, COD, ammonia - nitrogen, total phosphorus and so on. This process is the main process of the secondary biochemical treatment process of activated sludge method.
