摘要：

摘要：介绍了超滤技术的特点，结合漯河某净水厂项目，对比了压力式超滤系统和浸没式超滤系统的膜组件参数、建设成本及运行成本等，确定压力式超滤膜系统可以长期维持较高膜通量运行，较浸没式超滤系统更具技术、经济优势。最后指出，在净水厂采用“混凝沉淀+超滤”的新型短流程工艺，应优先选择铁盐混凝剂，严格控制沉淀池出水的混凝剂和助凝剂残余量。

Abstract:

Abstract:This paper introduced the characteristics of ultrafiltration technology,compared the membrane component parameters,construction cost and operating cost of pressure type ultrafiltration system and immersion ultrafiltration system combining a certain water purification plant in Luohe,and confirmed that the pressure type ultrafiltration system could maintain higher membrane flux operation for a long time,which carries more technical and economic advantages than the immersion ultrafiltration system.At the end of this paper,the authors pointed out that the ferric salt coagulants are preferred and the residual volumes of discharged coagulants and coagulant aids from precipitation tank should be strictly controlled in the water purification plant,which adopts the new type shortened flow process of “coagulative precipitation + ultrafiltration”.
