摘　　要：介绍了印制电路板废水中的含镍废水、含氰废水、无机水洗废水回用处理的工程设计及运行,采用"预处理+p H调整+混凝沉淀+物理过滤+DF系统+膜处理"工艺。实际运行结果表明,该工艺运行稳定,经济可行。出水COD≤32 mg/L,SS、Cu、Ni的质量浓度分别≤19、≤0.39、≤0.11 mg/L,CN-未检测出,p H为7.5,水质达到GB/T 19923-2005和GB 21900-2008)的回用及排放标准,可为目前PCB废水的回用处理提供技术借鉴。The design and operation of reuse treatment of nickel containing wastewater, cyanide containing wastowater and inorganic washing wastewater in PCB wastewater were introduced. The technological process of ＇pretreatment ＋pH adjustment ＋ coagulation sedimentation ＋ physical filtration ＋DF system ＋ membrane treatment＇ was employed. The actual nmning data showed that, the process was stable and economical. The COD and mass concentration ofSS, Cu, Ni was less than 32 mg/L and 19, 0.39, 0.11 mg/L respectively, and CN- was not detected and pH was 7.5. The effluent quality could met the standard of GB/T 19923 -2005 and GB 21900-2008 and the process provided technical reference for the reuse treatment ofPCB wastewater at present.
