摘要
通过大量的试验，探讨了上向流聚苯乙烯滤料直接过滤原水时凝聚剂种类对过滤效果的影响．试验结果表明：联合投加硫酸铝和阳离子聚合物（Ｔ３０１０）有利于改善滤出水水质和降低水头损失．
Numerous tests were made to determine the influences of coagulant types on the effect of direct filtration of water using an upflow polystyrene filter.The test results showed that dosing both aluminium sulfate and cationic polymer T3010 could improve the quality of the effluent and reduce the headloss as well.
