中文摘要:
      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
英文摘要:
      Quaternary ammonium salt of chitosan derivatives N-(glycidyltrimethylammonium) chitosan chloride(GTCC) is synthesized by reacting chitosan with glycidyltrimethylammonium chloride. It is proved that the coagulation of GTCC features small dosage and effective turbidity and oil removal by a series of coagulation experiments of treatment of oil refining wastewater. In addition, the amount of SRB in the oil refining wastewater and liquid after coagulation by GTCC was tested. It is proved that GTCC has a high ability of killing SRB. So a cooperative theory of coagulation-sterilization is proposed.
