Previous studies show that PHA (poly hydroxy alkanoate) in activated sludge participates in the biological phosphorus removal on the wastewater plant. We examined the relationship between phosphorus removal and PHA concentration under anaerobic, anoxic and oxic conditions in the laboratory.

After we arranged the actual operating data, such as ratio of return sludge, influence of rainfall and ratio of nitrate feed and so on, we examined the best operation for phosphorus removal from principal of management, and drown up effective operation and management of A2/O process.

Keywords: Optimization Method of Influent Load; PHA shortage; Phosphorus removal
