摘　　要： 研究了不同条件下复合菌液对生活污水中污染物CODCr、BOD5、氨氮、总磷的去除能力,实验结果表明:复合菌液在曝气和不曝气条件下对污染物都有很好的降解能力,而曝气条件下降解能力更高。在复合菌添加量为5/1000和曝气时间为24h时,污染物的去除效果最佳,CODCr、BOD5、氨氮、总磷的去除率分别为75.31%、72.32%、72.38%和70.61%。 The effect of compound bacteria on degrading the pollutants in domestic wastewater,such as COD_(Cr), BOD_5, ammonia nitrogen and total phosphor, were studied. The experimental result shows that high_efficiency compound bacteria have good degradation abilities both under aerating and anaerating condition, and the degrading efficiency is better under aerating. When the addition of compound bacteria is of 5/1000 for 24 hours of the aerating time, the effect of degrading pollutants is best, in which the removal rate of COD_(Cr), BOD_5, ammonia nitrogen and total phosphor is 75.31%, 72.32%, 72.38% and 70.61%, respectively.
