Effect of solids retention time on nitrogen and phosphorus removal from municipal wastewater in a sequencing batch membrane bioreactor

A two-biofilter system operated under alternate conditions of anaerobic/aerobic was tested to simultaneously remove nitrogen and phosphorus from sewage. The factors affecting simultaneous removal of nitrogen and phosphorus by the two-biofilter system were investigated. Those factors appeared to be influent COD/T-N and COD/T-P ratio, nitrogen loading rate and hydraulic retention time. Nitrite and nitrate produced in the biofilter in aerobic condition affected phosphorus removal by the two-biofilter system. The amount of biomass wasted during the backwash procedure also affected total nitrogen and phosphorus removal by the system.

Technical Features

The application of reversed A2/O process in practice in China is mainly discussed in this paper. As a new process on nitrogen and phosphorus removal, principle and technical features of reversed A2/O process are also summarized. The application in rebuilt wastewater treatment plant shows that reversed A2/O process not only has merits on high nitrogen and phosphorus removal efficiency, but also has merits on energy saving. The application in newly-build wastewater treatment plant shows that infrastructure and equipment investment of reversed A2/O process economized 15% and 10% respectively, compared to conventional A2/O process. The practical application shows that reversed A2/O process is a new nitrogen and phosphorus removal process, which is suitable for China's national conditions.
