高浊度微污染黄河水的处理工艺

Treatment Process of High Turbid and Slightly-Polluted Water from the Ye llow River

在混凝处理中采用5%的清水回流与PAC+HPAM联合投加相结合的方法,形成高浊度微污染黄河水的处理工艺。应用该技术对高浊度水进行生产性试验,除浊效果与传统工艺相比约提高40%～50%,对有机物和NH3-N的去除率也有所提高,同时可使出水的致突变活性呈阴性。

clean water backflow plus PAC +HPAM coagulation process was employed to treat high tur-bid and slightly-polluted water fro m the Yellow River at a pilot scale.Co mpared with the traditional ones,th is pro-cess increased 40%～50%in turbidity removal,and also increased the remo val of organic substances and NH 3 -N.At the same time the mutation activity of the treated water showed negative.
