摘　　要：介绍了连续流双污泥亚硝化反硝化除磷系统的启动,主要研究了实验过程中COD、TP、NH4+-N在各个反应器中的浓度变化以及总去除效果,NO2--N、NO3--N的浓度变化规律,NO2--N在亚硝化池内的亚硝化率。COD在各反应池内都能被去除,TP主要在缺氧段被去除,NH4+-N主要在亚硝化段被去除,NO2--N、NO3--N的最大积累量分别为13.96、16.98 mg/L;当出水硝氮质量浓度达4.25 mg/L时,会破坏厌氧环境。The start-up of continuous flow double sludge nitrosation denitrification dephosphorization system is in- troduced. The removing effects of COD ,TP,and NH4-N in the process of experiments, the concentration changing rules of NO2--N and NO3--N, and the total nitrosation rate of NO2--N in the nitrosation pool have mainly been studied. COD could be removed in every reaction pool. TP is mainly removed in anoxic section. NI-L-N is mainly re- moved in the nitrosation section. The maximum cumulants of NO2--N,and NO3---N are 13.96 mg/L and 16.98 mg/L,re- soectivelv. When the concentration of nitrate in effluent is 4.25 mg/L, the anaerobic environment might be destroyed.
