In this work, inorganic/organic complex flocculant was studied for treating dyeing wastewater. The results demonstrated that treating the dyeing wastewater with complex flocculent had not only good chromaticity removal rate but also fewer dosage of flocculent. When the adding dose was 750ppm, the chromaticity removal rate reached to 99%. This method has the advantages of high chromaticity removal rate, less sludge, large flocculation particle and rapid precipitating velocity etc.

研究了几种有机、无机絮凝剂和两种无机 /有机复合絮凝剂对活性艳红 K- 2 BP模拟废水以及实际废水的处理效果。结果表明 ,无机 /有机复合絮凝剂对活性染料具有很好的处理效果 ,且节省絮凝剂用量 ,当投加量为 75 0 mg/L时 ,脱色率达 99% ,沉清液基本无色 ,具有脱色率高 ,沉淀污泥少 ,絮凝颗粒大 ,沉淀速度快等优点

Several kinds of inorganic/ organic complex flocculents were studied for chrome tanning waste water treatment.We get the suitable complex flocculent and dosage of it.After the treatment with complex flocculent, the solution is of no color. This method has the advantages of less sludge,large flocculation particle and rapid precipitating velocity ,at the same time,the removal rate of Cr(Ⅵ) is 96.19%?

研究了几种无机、有机絮凝剂和 4种无机 /有机复合絮凝剂对铬鞣废水的处理效果。并确定了比较合适的复配方式和复配关系。当投加的量确定时 ,澄清液无色 ,具有沉淀污泥少、絮凝颗粒大、沉降速度快等特点 ;Cr( )的去除率可达 99.96 %。

The wastewater of papermaking was regarded as researching object. The wastewater was cleaned by several flocculants,the result was compared. The best flocculent was elected and used. The best flocculent is complex flocculent PAC, PFS and CPAM. The pure liquor will be oxidized, the pure liquor will be used circularly behind oxidization. So the way enormous water resource can be saved.

以造纸废水为研究对象,采用几种絮凝剂对其进行处理,对几种絮凝剂的处理结果进行了比较,筛选出最佳的絮凝剂,用选出的最佳絮凝剂即复合絮凝剂——聚合氯化铝、聚合硫酸铁和阳离子聚丙烯酰胺,将上清液进行氧化,氧化后的清夜可以循环利用,节约了大量的水资源。
