| 中文摘要: |
| 研究了壳聚糖与无机絮凝剂的复合效果,实验结果表明,复合絮凝能够相互促进壳聚糖与无机絮凝剂各自的絮凝性能,显著提高浊度与有机物的去除效果.在壳聚糖絮凝剂分别与三种常用无机絮凝剂(硫酸铝、氯化铁和聚合铝铁)的复合絮凝的效果表明,其中聚合铝铁跟壳聚糖的复合絮凝取得了更好的效果,在最佳条件下,其浊度、CODMN和UV254的去除率分别达到了97%、44%和55%.另外,无论是壳聚糖单独使用还是与聚合铝铁复合使用,在最佳的情况下,都使出水中的残留铝浓度小于检测方法的检出限. |

| In this paper,the combined flocculation of chitosan and inorganic flocculant was tested.The experiment results show that the combined flocculation can reciprocally promote each flocculant behavior,remarkably enhance the effect of removing turbidity and organic matter.The combined flocculation effect of chitosan flocculant and three inorganic flocculant(aluminium sulfate,ferric chloride and polymeric aluminium-ferric)show that the combined flocculation effect of chitosan flocculant and polymeric aluminium-ferric is best,under optimum conditions,the rate of removing turbidity,CODMN and UV254 is 97%,44% and 55% respectively.In addition,no matter chitosan combined with inorganic flocculation or not,on the best conditions,the residual aluminum concentration is less than the examination methods limit in effluent water. |
