摘　　要：电化学方法处理难降解有机废水是一种很有前途的技术,对难于生物降解有毒污染物的去除非常有效,是目前水处理研究中一个较为活跃的领域。本文设计了一个利用电化学方法处理造纸中段废水的简易实验方案,通过多组数据控制参数由实验结果找出最佳运行参数,整理并分析实验数据,由实验结果得出电化学处理废水可以在很大程度上提高废水可生化性的结论。当电解时间为80min,电流为1.6A时,制浆造纸中段水的BOD5/COD达到最大值0.53,生化性最好。The electrochemical method for the treatment of organic wastewater is a promising technology. It is difficult to remove toxic pollutants very effectively by biodegradation. It is a very active research field in the treatment of wastewater. In this experiment an simple experimental program to deal with difficult biochemical effluent with electrochemical method was designed. From the results of multiple sets of data from the control parameters we can find the best operating parameters by collection and analysis of the experimental data. Electrochemical treatment of wastewater can significantly increase the biodegradability of the effeuent. As the electrolysis time is 80 minutes, electricity is 1.6 A, the BOD5/COD of the effluent from screering, cleaning and bleaching reaches the maximum value,0.53 which means the best biodegradability.
