摘　　要：采用混凝-微电解法作为预处理工艺,与生物处理工艺联用处理豆制品废水.实验结果表明,本实验处理豆制品废水的最佳初始pH值为3.5～4.0,混凝剂最佳选择为聚合氯化铝(PAC),其与助凝剂聚丙烯酰胺(PAM)的投放质量浓度分别为0.5 g·L^(-1)和10 mg·L^(-1),可去除废水中27.5%的COD,微电解处理效果最佳的反应时间为6 h,有效去除废水中53.6%的COD.The coagulation-microelectrolysis was used as a pretreatment process,and then bean product wastewater was treated combining with the biological treatment process.The results show:the optimal initial pH for the treatment of bean product wastewater was 3.5~4.0;the best choice of coagulant was PAC;the optimal concentrations of PAC and PAM were 0.5 mg·L^-1 and 10 mg·L^-1,respectively,which could remove 27.5%of COD in wastewater;the optimal reaction time for microelectrolysis treatment was 6 h,and 53.6%of COD in wastewater could be removed effectively.
