摘　　要：采用新型序批式生物膜法(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,正常工况下出水TP去除率为84%,TN去除率为80%。DO是SBBR同时硝化反硝化的控制因素,且适当缩短泥龄有利于除磷。A new sequencing batch biofilm reactor(SBBR)was used to treat real domestic wastewater.The characteristics of simultaneous nitrification and denitrification and removal phosphorus of sequencing batch biofilm reactor(SBBR)in treating domestic sewage under the condition of anaerobic/anoxic process were studied.Results from the studies were presented that under the optimization situation of treating process,effluent TN removal rate was 80% and its TP removal rate was 84%.DO was the key factor of simultaneous nitrification and denitrification of SBBR.Reducing SRT properly was availability to removal phosphorus.
