摘　　要：采用经实验运行得到SBR工艺处理化粪池出水的合理的操作模式,能获得90%以上稳定的COD_(cr)去除率及更好的BOD_5去除效果,NH_3-N去除率大于75%,TN去除率大于45%.并考察了污泥浓度、泥龄、污泥负荷与处理效果的关系,以及闲置期对反应周期的影响.实验结果表明,SBR工艺对处理水质、水量负荷变化很大的化粪池出水,是一种理想的工艺选择.The reasonable operation model of SBR for treating septic tank effluent in a laboratory scale was obtained The result showed that in operating parameters according to the operation model, COD removal efficiency was more than 90%.ammoniacal nitrogen over 75% and total nitrogen over 45%. It was observed the relationships among the effects of sludge concentration, sludge age and sludge load on treatment efficiency and effect of idle time on reaction period.It also indicated that SBR process is an ideal option for treating septic tank effluent of various loads.
