摘　　要：探讨了自制有机高分子重金属捕集絮凝剂CU3#对铜离子、铅离子的捕集机理，研究了其处理含铜离子、铅离子废水的处理条件，并研究了其他物质和离子对铜离子和铅离子去除效果的影响。研究结果表明，在pH7～14范围内，快速搅拌时问2min，慢速搅拌3min，CU3#对含铜离子的污水处理后其上清液中所含铜离子为1．2mg/L，对铜离子的去除率达到99．4％，完全达到国家排放标准；在pH7～14范围内，快速搅拌时间3min，慢速搅拌3min，CU3#对含铅离子的污水处理后其上清液中残余铅离子0.8mg/L，去除率99.6％，达国家一级排放标准。In this paper, the chelating mechanics of self-made organic macromolecule heavy metal trapping flocculant CU3# with Cu^2＋ and Pb^2＋ were studied. The effects of removing Cu（ Ⅱ ） and Pb（ Ⅱ ） with heavy metal chelating agent CU3# were studied in wastewater and the effects of the other things and metal ions were also studied. When the range of pH value is 7 ～ 14, faster stirring time is 2 minutes and slower stirring time is 3 minutes, the residual dosage of Cu（Ⅱ） treated by heavy metal chelating agent CU3# is less than 1.2 mg/L and the removal rate of Cu（ Ⅱ ） from wastewater is more than 99.4%. When the range of pH value is 7 ～ 14, faster stirring time is 3 minutes and slower stirring time is 3 minutes, the residual dosage of Pb（Ⅱ） treated by heavy metal chelating agent CU3# is less than 0.8 mg/L and the removal rate of Pb（Ⅱ） from wastewater is more than 99.6%.
