摘　　要：混凝法处理高浓度有机废水存在沉降速度慢 ,效果不理想的问题。研究了采用活性白土等九种助凝助沉剂在铝盐混凝剂处理高浓度有机废水时的作用 ,继而进行优化组合 ,结果良好 ,例如用微量聚丙烯酰胺和0 .0 12 5 %A物质 (以废水质量计 )作为聚硅氯化铝的助剂处理淀粉化工废水 ,浊度去除率 97.0 % ,COD去除率87.2 % 。The treatment of high concentration organic wastewater with the normal sediment has some problems such as slow settling speed, no ideal effect. Study the effect of nine kinds of coagulant aid and precipitant aid such as atlapulgite to coagulant aluminum salt dispose of organic wastewater of high concentration, then optimize and assemble. As a result, treat the organic wastewater of high concentration with the matter A that is 0.0125% of wastewater's mass and little polyacrylamide as the assistants of coagulant aluminum salt, the rate of turbidity removed is 97.0%, the rate of CODcr removed is 87.2%,with rapid sedimentation.
