超滤膜在饮用水厂升级改造过程中的应用日益增多,超滤膜与常规饮用水净化工艺的适配方式成为设计人员面临的首要问题。总结国内饮用水厂升级改造过程中的超滤膜组合工艺,分析预氧化、混凝、沉淀、过滤等预处理单元对超滤膜的影响,并基于超滤膜组合工艺的膜污染减缓机制对不同组合工艺进行了适配性评价,旨在为水厂设计提供借鉴。
The application of ultrafiltration membrane in the upgrading process of drinking water plant is increasing day by day. The adaptation of ultrafiltration membrane and conventional drinking water purification technology becomes the primary problem for designers. Summarizes the process of upgrading and rebuilding the domestic drinking water plant ultrafiltration membrane combination process, analysis of pre-oxidation, coagulation, sedimentation, filtration and other pretreatment unit on the ultrafiltration membrane, membrane ultrafiltration membrane combination based on mitigation mechanism of mitigation Adaptability evaluation of different combinations of processes designed to provide reference for waterworks design.
