Process characteristics and engineering analysis of integrated sewage treatment in Chengdu:

Stable operation and strong operability. Activated sludge process is generally used for water with large water volume, certain fluctuations in water quality, medium or high concentration water quality. At the same time, due to the long cultivation time of activated sludge (usually about 30 days), the operation and management of the system are complicated, and there are certain requirements for operators.

The sewage quality is set according to conventional standards: CODCr ≤ 300mg/l，BOD5 ≤200mg/l， Based on previous engineering examples in our factory, we recommend using the biofilm treatment process and plan to use an integrated sewage treatment equipment with A/O biological contact oxidation process as the main body, using a biochemical treatment method.
