Yunnan sewage treatment equipmentWhat are the process specifications?

The design of WSZ-A equipment is mainly aimed at the treatment of domestic sewage and similar industrial organic sewage. The main treatment method is to use a relatively mature biochemical treatment technology - contact oxidation method. The water quality parameters are designed according to the general domestic water quality, with inlet BOD of 200mg/l and outlet BOD of 20mg/l. It consists of six parts: (1) primary sedimentation tank; (2) Contact oxidation tank; (3) Secondary sedimentation tank; (4) Disinfection pool and disinfection device; (5) Sludge tank; (6) Fan room, fan.

The following are discussed separately:

Vertical flow sedimentation tank, the upward flow velocity of sewage in the sedimentation tank is 0.6-0.7 mm/s, and the settled sludge is lifted to the sludge tank by air. (Note: WSZ-A O.5-5m/h does not have a primary sedimentation tank)

Roots blower, capable of automatic alternating operation. The operating life of a single wind turbine is about 30000 hours.

The above are some discussions on sewage equipment. Do you have any further understanding of it.
