摘　　要：通过水解酸化-SBR-混凝工艺处理榨菜废水试验得出,在水解酸化池HRT为6h,SBR条件为0.5h进水+10h好氧+4h厌氧+1h沉淀+0.5h闲置(曝气量6L·min-1,污泥浓度4000mg·L-1),混凝试验PAC和PAM投加量分别为300mg·L-1和6mg·L-1条件下,COD、SS、氨氮和总磷平均去除率分别为96%、85.03%、84.9%和95.32%,出水水质达到污水综合排放标准二级标准。The treatment of mustard tuber wastewater by the process of hydrolysis-acidogenesis-SBR-coagulation showed that when the optimal HRT of hydrolysis-acidogenesis was 6 h, the optimum operating procedures of SBR was： filling 0.5 h＋aeration 10 h＋anaeration 4 h＋seting 1 h＋standing-by 0.5 h （inflatable volume：6 L·min^-1, MLSS：4 000 mg·L^-1）, and the dosages of PAC and PAM were 300 mg·L^-1 and 6 mg·L^-1 respectively, the average removal rates of COD, SS, NH4^＋ -N and TP were respectively 96%, 85.03%, 84.9% and 95.32% ,which reached the second.class standard of sewage comprehensive discharge standard （GB8978-1996）.
