根据某印刷电路板企业生产废水的水质特点，对废水进行分类收集处理后，采用微电解／斜板沉淀／生物接触氧化工艺处理综合废水。工程运行结果表明，该工艺处理效果稳定，出水水质符合《污水综合排放标准》（GB8978-1996）的一级排放标准。%The wastewater from a plant of printed circuit board were collected and treated separately according tothe wastewater quality. The integrated wastewater was treated by microelectrolysis/plate setter/biological contact oxidation process. The operation results showed that the effluent quality reached the first class of ＂Integrated Wastewater Discharge Standard＂ （GB8978-1996）.This research obtained a feasible approach for PCB wastewater treatment.
