将壳聚糖改性合成壳聚糖季铵盐用于炼油废水的絮凝处理 .实验表明 ,其投药量少 ,除油除浊效率高 .对絮凝后的上清液进行硫酸盐还原菌检测 ,结果表明有较好的杀菌作用 .在此基础上提出了壳聚糖季铵盐絮凝—杀菌共同作用的机理
The chitosan-modified chitosan quaternary ammonium salt was used in the flocculation treatment of refinery wastewater.The experiments showed that the chitosan-modified chitosan quaternary ammonium salt is less flocculated and the efficiency of degreasing and turbidity removal is high.The sulfate-reducing bacteria were detected in the supernatant after flocculation, The results show that there is a good bactericidal effect.On the basis of this, the mechanism of chitosan quaternary ammonium flocculation-bactericidal action
