The main conclusion are as bwlow : 1. for microflocilation / uf progress, ferric salts were better than aluminum salts ; the more dose of coagulant, the high removal rate of organic matter. however when dose increased to a certain level ( 6mg / l alo2 ), fouling was higher instead
主要成果和結論如下: 1 .微絮凝-超濾工藝中，鐵鹽混凝劑比鋁鹽要好;隨著混凝劑投加量的增加，有機物的去除率也隨著增加，但當混凝劑投加量增加到一定量（以al2o3計為6mg / l ）時，反而會加劇膜污染;投加pam （聚丙烯酰胺）對提高有機物去除率沒有幫助，但可以緩解膜污染。
