| Abstract: | 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. |
