【摘要】 研究了以天然高分子壳聚糖复配而成的新型高效复合絮凝剂在不同的工业污水处理中的应用,通过试验表明,该絮凝剂与传统絮凝剂相比,COD,SS及重金属离子的去除率均可提高10%~20%,成本下降30%~50%,且2次污染大大减少,具有明显的经济效益和环境效益。更多还原

【Abstract】 Chintin and chitosan are a kind of natural glucosamine polymers,which possess unique function and have wide use in many fields.The application of multiple fiocculant of chitosan to the treatment of different kinds of industrial wastewater was studied.The treating results showed that when compared with the traditional flocculant such as PAC,COD,SS and removal rate of this floeculant went up 10%～20%,the treating cost of this flocculant was reduced by 40%～50%,and its second pollution decreased greately.Therefore,this flocculant is of obvious economic and environmental benefits.更多还原
