摘　　要：西北某化工园区拟对其污水处理厂达标排放的准IV类水标准的尾水进行再生水回用,设计工艺拟选用CDRO+MVR的处理工艺,达标产水经送水泵房送至各用水点。反渗透浓水进一步浓缩后采用MVR设备蒸发结晶,结晶产品通过分盐处置最终形成工业级氯化钠及硫酸钠,剩余杂盐外运至危废处置中心集中处理,实现近零排放。本工程的设计实施以期为相关工程提供借鉴参考。An industrial park in Northwest China plans to reuse the tailwater of quasi class IV water standard discharged by its sewage treatment plant.The CDRO + MVR treatment process is proposed.The produced water up to the standard is transmitted to all water consumption points through the water supply pump room;After further concentration,the reverse osmosis concentrated water is evaporated and crystallized by MVR evaporator.The crystallized products are finally formed into industrial-grade sodium chloride and sodium sulfate through salt separation.And the remaining miscellaneous salt is transported to the hazardous waste disposal center for centralized treatment,realizing nearly zero discharge.The design and implementation of this project is intended to provide a reference for related projects.
