摘　　要：根据太湖金墅原水冬季低温低浊的水质特点,探讨了采用沉淀池排泥水集中收集后回用,以期改善混凝沉淀效果的技术可行性,以及其对出水COD和余氯衰减情况的影响。结果表明,在合理控制回流比的情况下,经过深度处理后能取得预期的水质改善效果。According to the features of low temperature and low turbidity raw water in Taihu Jinshu in winter, the technical feasibility of the reuse of sludge discharge water from the sedimentation tank was discussed in order to improve the effect of coagulation and sedimentation. The influence on COD of outflow and decay of residual chlorine was also studied. The results showed that the expected improvement of water quality could be obtained after advanced treatment under the conditions of reasonable reflux ratio.
