摘　　要：采用Al2(SO4)3和自行合成的淀粉接枝丙烯酰胺(GCAM)对麦草浆E段漂白废水进行絮凝,探讨pH值、药品投加量对絮凝效果的影响。结果表明:絮凝剂GCAM具有较好的处理效果,在GCAM添加量为32mg·L-1时,浊度、CODCr、SS和色度的去除率分别为97.4%、76.7%、96.5%和85.0%,与硫酸铝絮凝相比,产生的污泥量仅为6%左右。When E bleaching effluent of straw pulp were flocculated by Al 2 （SO 4 ） 3 and GCAM,the effects of pH and dosage were studied.The experimental results showed that flocculent GCAM had good treatment effect.When the dosage of GCAM was 32mg·L -1 ,the removal rate of turbidity,COD Cr ,SS and colority respectively was 97.4%,76.7%,96.5%and 85.0%.Compared with aluminum sulfate flocculation,sludge was only about 6%.
