摘　　要：采用混凝沉淀-过滤工艺对再生浆造纸废水进行研究。研究结果表明，采用硫酸亚铁酸洗废液混凝剂是行之有效的，经此工艺处理后，COD、SS和色度的去除率分别为90％、96％和95％左右。处理后废水水质达到排放标准且可全部回用于生产，实现零排放。此工艺具有很好的应用前景，尤其适合北方寒冷地区。It is an effective measure that treats the waste water from reproductive pulppapermaking with ferrous sulphate as coItgulantS Dropping some ferrous sulphate fluid intothe waste water, the coagulants wll settle out and then let the water thr0ugh a filter, theremove rate of the COD, SS and color of the water will be about 90%' 96% and 95%. Thequality of the water will come up to the dIaing standard. The water can be drained out aswell as can be all recovered to use in paperfnaking. The new water treatment technique isespecially good for North frigid area.
