摘　　要：采用悬浮澄清池-硅藻土动态膜联用工艺对淮河微污染原水进行试验研究.研究结果表明:该工艺对浊度、UV254和CODMn具有较好的去除效果.通过增大错流出水比,系统对CODMn和UV254的去除率均有所提高,运行周期也会增大,但对浊度的去除没有明显影响,同时膜压差的上升也会加剧.The compounds of sludge blanket clarifier and diatomite dynamic membrane were conducted to the treatment of micro-polluted raw water in Huaihe River. The results indicated that the system removed turbidity and UV254 and CODMn with a high efficiency. The remove of CODMn and UV254 was raised by en larged ratio of cross-flow to effluent, and the operational cycle was also extended. However,there was no obvious influence on the remove of turbidity, the increase of transmembrane pressure became aggravated during the time of experiment.
