摘　　要：设计废水深度处理工艺路线,实现化工厂废水零排放的目标。废水经预处理单元、膜回收单元、蒸发回收单元后,回收淡水电导率均在130μS/cm以下,水质较好,可回收利用。深度处理主要装置为膜生物反应器、超滤装置、膜回收装置和三效蒸发器,工艺路线合理,可为其它浓盐水处理项目提供参考。Design a treatment process route for industrial effluent,to achieve the goal of zero discharge.After the treatment of pretreatment unit,membrane recovery unit and evaporative recovery unit,the water conductivity is below 130μS/cm,it can be recycled.The main equipments contain membrane bio-reactor,ultra-filtration and triple-effect evaporation.The process is reasonable,which can be referenced by other concentrated salt water treatment project.
