| 摘 要： | 本文报导了一体化膜混凝反应器(MCR)，该设备采用连续进水、间歇出水的运行方式，对Ⅱ类和V类及劣V类地表水进行处理。结果表明：MCR对浊度、有机物和细菌有良好的去除效果；采用合适的投药量，出水水质可以满足生活饮用水卫生规范(2001)的要求。试验从2002年7月运行到12月，滤饼层和膜污染阻力之和仅占膜总阻力的25．4％；对膜进行清洗，发现膜比通量能恢复到新膜的99．7％。

| Abstract: | An integrated device,based on microfiltration and coagulation process,was developed to treat micro-polluted surface water.Continuous raw water feeding and intermittent finished water drawing were adopted during the operation.It was found that there were good removals on turbidity,organic matters and bacteria with MCR.When proper dose is added into MCR,the finished water can meet the requirement of Sanitary Standard for Drinking Water Quality(2001).The resistance of cake layer and fouling was only 25.4% of the total membrane resistance after the operation from July to December 2002.The specific flux recovered to 99.7% of the initial value after the cleaning of the membrane. |
