有机高分子螯合剂在氰化废水治理中的应用研究

Research progress and application of organic polymer chelating agent in cyanidation wastewater

用一种新型有机高分子螯合剂处理含氰废水中的Pb2+、Hg2+等重金属离子,对其处理效果与无机沉淀剂Na2S进行了比较。结果表明,该螯合剂对氰化废水中的Pb2+、Hg2+等重金属离子的捕集效率高,处理后的废水可排放,且成本低、设备简单。

A new organic polymer chelating agent and a inorganic precipitant Na2S removed the heavy metal ions Ag＋、Cu、Pb2＋、Hg2＋in cyanidation wastewater respectively.The report showed that the cyanidation wastewater handled by the organic polymer chelating agent was better and up to discharge standards.It was low cost and simple equipment.
