摘要
采用新型的复合聚铁硅絮凝剂处理生活污水 ,通过混凝实验探讨了复合聚合硫酸铁硅PFSS、聚硅酸铁PSFS的脱色除浊、COD去除及氮、磷去除效果 ,并与常用的聚合硫酸铁PFS进行絮凝效果及经济成本的对比分析。结果表明 ,用复合型聚铁硅絮凝剂处理生活污水絮凝效果好 ,除浊率达 99%以上 ,脱色率 6 5 %～ 70 % ,COD去除率 70 % ,而且氮、磷去除效果好 ,成本低廉 。
Compsite polyferric silicate sulfate was utilized to treat domestic sewage, its flocculating effects were studied by coagulating test, meanwhile its flocculating effect and cost were compared between this new type of flocculant and ployferric sulphate used widly. The results showed that the domesic sewage treatment with compsite polyferric silicate sulfate has excellent flocculating effects, tuebidity removal rate is beyond 99%, color removal rate is 65%～70% and COD removal rate is about 70%. In addition, it has good removal effect of nitrification and phosphrization, the cost of this new flocculant is also lower, showing good potential application.
