Industrial waste water after treatment is reduced in recent years, continued to grow, but city life sewage accounted for over 51% of the water pollution. This design is about the sewage treatment plant in Guangzhou, huangge town . The construction of this plant is 30000 m3/d. The main origin of the sewage is the sanitary sewage and the industrial waste. The main polluting is the NH3N, BOD, COD. It is suitable to use the biochemistry processing method. After the parison of the plan, the Oxidation Ditch craft was chosen as the process. The elimination rate of the NH3N, BOD, COD respectively achieved %, %, %. The outlet water of the treatment meets the level two of the National Sewage Discharge Standard (GB89781996). The mixed liquor of the sewage and the activated sludge are sporting unceasingly in the oxidation ditch. It is good to exclude BOD、 COD and take off the nitrogen and the phosphorus. Additionally, the simple processing, the few buildings, the varied structure, the nimble movement, and the good stability of the movement, the province initial cost, the low operating cost, the convenient operation and management, the good quality of the letout water are also the places which the oxidize ditch is better than the other technology.
