| 摘 要： | 研究3种重金属离子处理剂对铬鞣废水的处理,确定每种处理剂的最佳应用pH和最佳投加量,以及3种处理剂的最佳复合配比.结果表明:这3种处理剂处理铬鞣废水的最佳pH均为8.5左右;捕集剂、沉淀剂、去除剂的最佳投加量分别为7.0、8.0、9.0,mL/L,铬去除率均可达到97%以上;而由3种处理剂以适当比例复配的絮凝剂,铬的去除率可达99%以上,处理后的上清液和回收的铬都可以再用于皮革生产.

| Abstract: | Three kinds of flocculants for the treatment of industrial wastewater containing chromium were studied.The pH and the agents dosage can be determined in an appropriate range for applications,at the same time the radio of the compound for the 3 kinds of treatment agents can also be found out.The experimental results show that the appropriate pH are all at 8.5.The removal of the chrome in the tanning wastewater can be up to 97% while the optimum dosage of trapping agent,precipitating agent and remover are 7.0... |
