中文摘要
为提高生活污水氮磷处理效率和节约碳源，以软性填料的序批式生物膜法(SBBR)处理生活污水，研究在厌氧/缺氧模式下生物聚磷以及同时硝化反硝化的特性。试验表明，合适的工况下出水TP去除率为84%，TN去除率为80%，证实了SBBR同步的脱氮除磷的可能性。同步脱氮与生物除磷由不同的微生物群落完成，为获得稳定的生物脱氮除磷效果必须综合考虑各种反应参数。其中，溶解氧和污泥龄对SBBR脱氮除磷有重要影响。在这些影响因子中，DO是SBBR同时硝化反硝化的控制因素，而适当缩短泥龄可以很好除磷。
英文摘要
In order to improve the efficiency of biological treatment of living sewage with rich nitrogen and phosphorus, and reduce the carbon source, the character of simultaneous nitrification and denitrification and biological phosphorus removal of Sequencing Batch Biofilm Reactor(SBBR) in treating living sewage under the condition of anaerobic /anoxic process was studied. An new Sequencing Batch Biofilm Reactor(SBBR) with soft carrer was used to treat real living sewage．Result showed that under the optimization situation of treating process, effluent TN removal rate was 80％，effluent TP removal rate was 84％. It demonstrated that it was possible to remove N and P simultaneous in SBBR. For the aim of obtaining efficient effect of both biological N and P removal, various influencing factors were studied. Among the influencing factors，DO and SRT were important to both N and P removal. DO was the key factor for the simultaneous nitrification and denitrification of SBBR. Reducing SRT was availability to removal phosphorus.
