摘　　要：采用模拟配制的生活污水 ,研究循序间歇反应器 (SBR)工艺的脱氮除磷效果和污泥沉降性能 .试验结果表明 ,通过了状态调控阶段 ,反应器中形成了同时具有脱氮除磷能力的好氧颗粒化污泥 .其中 ,反应器对COD和P的去除率分别为 90 %和85 %左右 ;NH3 N和TN去除率分别达到 90 %和 80 % ;颗粒污泥的SVI值约为 5 0 ,出水水质好 .The removal efficiency of P and N and settlement characteristics of sludge were studied in SBR process by using synthetic domestic wastewater as feed. It is found that the aerobic granular sludge was formed in the reactor under the proper operating conditions, which can show excellent settling ability. The sludge is mainly 0.2—1.0mm in diameter and 50 of SVI. Compared with the experimental results before sludge granulation, the removal efficiencies of COD, P, NH 3 N and TN are highly improved, It can remove P and N simultaneously with 90% removal for COD, 85% for P, 90% for NH 3 N, and 80% for TN.
