| 摘 要： | 以洗浴废水为研究对象，比较了铝盐、铁盐及有机高分子混凝剂对洗浴废水中的LAS去除效果，筛选出聚合氯化铝（PAC）作为混凝剂处理效果较好，进而采用单因素试验研究了混凝剂的投加量，废水的pH，静沉时间，搅拌强度和搅拌时间对LAS去除率的影响，结果表明PAC投加量为45 mg/L，废水pH值为6.0～8.0，静沉时间为15 min，中速（150 r/min）搅拌3 min，慢速（50 r/min）搅拌10 min时混凝效果最佳，对LAS的去除率达44.75%。

| Abstract: | The experiment took bath wastewater as research object and adopted aluminum, iron and organic macromolecule as coagulants to examine the removal rates of LAS from bathing wasterwater,Determinted the PAC as the furthest coagulation,and the influenced factors such as the dosage of coagulation,the pH value,the sedimentation time,the stirring speed and stirring time were discussed using a method of one factor experiment,the result showed that the best operating conditions is that the doesage of45mg/L for PAC, 6.0~8.0 pH, 15min sedimentation time, 150r/min for 3min and 50r/min for 10min, the removal rates of LAS is 45.75%. |
