摘　　要：在序批式生物膜反应器(SBBR)中,当温度在较大的范围内(21～35℃)均能有效地实现亚硝酸型同步硝化反硝化。试验还发现反应过程中DO、pH和ORP的变化与有机物降解、氨氮化之间存在着很好的相关性,可以根据DO、pH和ORP在变化曲线上的特征点来判断SBBR法亚硝酸型同步硝化反硝化的终点。Using the sequencing batch biofilm reactor （SBBR） to treat municipal sewage of Guangzhou area, the average temperature range from 21℃ to 35℃ was proved very efficient for simultaneous nitrification and denitrification （SND） via nitrite. At the same time, the variation of DO, pH and ORP was well related to organic degradation and ammonia oxidation. So that judgment on the ending of simultaneous nitrification and denitrification via nitrite could be based on the varied curve of DO, pH and ORP.
