大孔阳离子交换树脂治理实验室废水中铜和铅的研究

The treatment of laboratory wastewater containing copper and lead by big aperture cation exchange resin

研究了大孔型阳离子交换树脂治理含铜和铅的实验室废水.在试验过程中对三种阳离子交换树脂进行筛选,讨论了流速、废水的起始pH值、温度、树脂再生次数对各重金属离子去除效果的影响.在确定的最佳试验条件下,处理实际实验室废水中的铜和铅时,去除率均达到99%以上.

This paper had reported one method processing laboratory waste water containing copper and lead using pocket cation exchange resin. The influences of such factors as kind of cation exchange resins, speed of flow, initiative pH value, temperature and regeneration of the resin on the removal rates of copper ion and lead ion were studied. Under the optimum conditions copper ion and lead ion removal rate of 99 % could be obtained for the treatment of real laboratory wastewater.
