摘　　要：介绍了"超滤+纳滤+两级反渗透"技术在电池工业污水处理回用中的应用,通过对电池工业氧化及老化工序生产过程中产生的污水进行高浓污水与低浓污水分质收集,控制低浓度污水进水电导率在12000μS/cm以内时,可采用膜分离技术进行处理回用,整体回收率达67%,脱盐率可达99.9%以上,产水电导率≤10μS/cm,可回用于生产过程。The “UF＋NF＋two-stage RO” technology applied in battery industrial wastewater treatment and reuse, through control the process of production,the wastewater can be divided into low concentration and high concentration two parts,if low concentration wastewater conductivity less than 12000 μS/cm,membrane separation technology can be used,the overall recovery rate was 67%, the desalination rate can reach more than 99.9%, and the effiuent water conductivity is less than or equal to 10μS/cm, can be used in the battery industrial production process.
