中文摘要:

      本文介绍了一种新型无机高分子絮凝剂－硅钙复合型聚合氯化铝铁（ＳＣＰＡＦＳ）在制革废水处理中的应用．在本实验条件下（絮凝剂用量０．３５～０．４０ｇ／Ｌ，混凝时间１５—２０分钟，ｐＨ值为６．０—９．０）该产品对废水的浊度去除率为９５．５％，ＳＳ去除率为９５％，ＣＯＤ去除率为９０％，对Ｃｒ（３＋）的去除率为８５％左右．各项性能都优于同样条伴下ＰＡＣ２倍以上．同时该絮凝剂还可用于生活饮水，生产用水及其它污水的处理，效果明显。

英文摘要:

      A new type of inorganic polymers-Sc PA Fs. which was used in treating the waste water of leather. is introduced in the paper. With this products removal of turbidity in the waste water is 95.5%. removal of SS is 95%, CoD is 90% and removal of Cr(3 ) is about 85%. at the experimental condition, such as flocculant 0. 35 - 0. 40g/L, coagulating time 15 - 20minutes and pH 8. O -9. 0. All properties have two times of advantages than that of PAC at same condition. The coagulant can be used in treating drinking water, water in production and waste water.
