【摘要】 采用有机高分子螯合剂与废水中的多种重金属离子发生螯合反应,生成稳定且不溶于水的金属螯合物来去除废水中的重金属离子,对四种螯合剂KS-3、KS-101、NKC-60、DTCR在不同加药量的条件下对含有Cu2+、Zn2+、Cr3+、Cd2+等重金属废水的处理效果进行了试验研究,结果表明,利用有机螯合剂的方法处理含重金属废水的效率很高,且有很好的应用前景。更多还原

【Abstract】 Using organic polymer chelating agent to chelate with several kinds of heavy metal ions in waste water, then these heavy metal ions will be removed by formed metal chelate compound featuring high stability and hardly dissolved by water. The experimental investigation is conducted on the treatment results of four kinds of chelating agents, like KS-3, KS101,NKC-60 and DTCR under the condition of adding different quantities of reagents to the waste water containing Cu2+、Zn2+、Cr3+、Cd2+etc. The result indicates that the method of heavy metal wastewater treatment with organic chelating agent provides a very high efficiency and has an excellent prospect of application.更多还原
