STUDY ON THE TREATMENT OF SEWAGE USING SEWER SYSTEM |
| |
Abstract: | Laboratory scale sewer systems for sewage treatment by immobilized cells on the surface of sewer were investigated and 4 processes, such as anaerobic, aerobic, anaerobic anoxic oxic,anoxic oxic,were compared for their removal efficiencies. The results indicated that the anoxic oxic process was the best and could remove more than 60% of contaminants in sewer systems using immobilized cells. The water quality of effluent could reach grade 2 standard of the sewage discharge standard of China. |
