摘　　要：首先采用加热煮沸、超声波、厌氧发酵等不同的方法对污泥进行了预处理,其中超声波破碎处理污泥的效果较好。再利用小球藻处理预处理后的污泥提取液,结果表明,小球藻对提取液中COD、TN、TP均有较高的去除率,最大去除率分别为97.4%,92.8%,73.9%。Firstly, different pretreatments of sewage sludge such as thermal treatment, ultrasonic waves, anaerobic digestion, etc. were taken in this study to get extractions, and the best result of the sewage sludge pretreatment was obtained by ultrasonic waves. Furthermore, the Chlorella sp was used to treat the sewage sludge extractions, and the experimental results showed that the high removal rate of COD, TN and TP was 97.4% , 92.8% and 73.9% respectively.
