Abstract:

A new kind of water purifying agent,dithiocarbamate,has successfully been synthesized with polyamine,adipic acid,carbon disulfide. The action mechanism of the agent is discussed. The experimental results show that when 50 mg/L of the agent is added to the polymer-containing wastewater,the oil removing rate is 63%,turbidity removing rate 90%,suspended solids removing rate 87%,and removing rate of COD 54%. Furthermore,the agents have certain corrosion inhibition and sterilization capacities.

Key words: dithiocarbamate, polymer-containing wastewater, water purifying agent

摘要：

利用多乙烯多胺、己二酸、二硫化碳等合成了二硫代氨基甲酸盐型净水剂,并对药剂作用机理进行探讨。实验结果表明:向含聚污水中投加50 mg/L该药剂,除油率达63%,除浊率可达90%,悬浮物去除率达87%,COD去除率达54%,且具有一定的杀菌缓蚀性能。
