脱盐水浓水节能回收改造总结

Sum-Up of Renovation of Energy Saving and Recovery of Concentrated Water from Water Desalinating Unit

介绍了脱盐水工艺流程及装置运行情况,分析了运行过程中存在的一级反渗透浓水利用率不高、电去离子浓水未充分利用等问题。通过对脱盐水流程进行改造,使各级浓水得到分级利用,提高了各级浓水的利用效果,年经济效益约65.06万元。

The desalinated water process flow and running status of the unit are introduced, and problems existed in operation such as low utilization rate of the first stage reverse osmosis concentrated water, underutilization of electrodeionization concentrated water etc. are analyzed. Through renovation of desalinated water process flow, concentrated water of each stage has been made staged utilization, utilization effects of concentrated water of each stage have improved, and annual economic benefit is about 650,600 yuan.
