摘要
对昆山傀儡湖微污染原水进行了粉末活性炭-混凝-超滤联用工艺的中试研究,研究表明混凝剂PAC投加量在30 mg/L的情况下,对浊度有较好的去除效果,但是对有机物的去除率较低.通过膜前在线再混凝,对CODMn的去除率有所提高,但对UV254没有明显影响;本中试对水中颗粒数也有较大的去除,去除率达到99%以上.
In this study,a pilot-scale hybrid PAC/coagulation/ultrafiltration system was conducted to treat micro-polluted raw water in Lake Kuilei,Kunshan city.The results indicated that the system removed turbidity with a high efficiency under a PAC dose of 30 mg/L,but with a low removal efficiency for organic matter.Though the removal of CODMn was raised by additional in-line coagulation before ultrafiltration,it was less effective in UV254 removal.Particle was almost eliminated with a removal efficiency of 99%.
