【摘要】 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。更多还原

【Abstract】 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.更多还原
