II. Process of Sewage Treatment System
The process of sewage treatment system is briefed as follows:
III. Process Description
The integrated sewage enters the regulation tank to adjust the water quality & quantity and to mix evenly. The integrated sewage in the regulation tank enters the hydrolysis acidification reaction tank for hydrolysis acidification reaction and precipitation separation. After temperature regulation, the effluent enters the anaerobic biochemical reactor for anaerobic biochemical reaction and precipitation separation.
The anaerobic effluent enters the A/O sewage treatment system to continue the biochemical treatment. The effluent enters the secondary sedimentation tank for precipitation separation. The secondary sedimentation tank effluent enters the coagulation reaction sedimentation tank for chemical phosphorus removal. Finally, the effluent discharge meets the standard.
