针对老旧水厂出水水质不稳定的问题及现有水厂升级改造的必然态势,以实际水厂改造方案为案例,对浸没式超滤膜系统的设计与应用进行详细阐述,总结出该改造工程具有流程短、通量小、占地面积小等特点。最后结合实际运行情况,对设计中包括设计通量、单格膜池规模和尺寸等的关键性参数及产水形式等关键问题进行分析探讨,为该技术用于水厂的升级改造提供技术参考与设计运行经验。 In view of the problem of unstable water quality of the old waterworks and the inevitable trend of the existing waterworks upgrading and upgrading, the design and application of the immersed ultrafiltration membrane system are described in detail with the actual waterworks reconstruction programs as examples. Project has a short process, small flux, small footprint and so on. Finally, according to the actual operation, the key issues such as the design flux, the size and dimension of single cell membrane, and the form of water production are analyzed and discussed in this design, which provides a technical reference for the upgrading of this technology. Experience with design and operation.
