用活化沸石处理含铅废水的试验研究

Experimental Researches on the Treatment of Lead Containing Wastewater with Activated Zeolite.

对用活化沸石处理含铅废水进行了试验研究。探讨了活化沸石用量、废水酸度、接触时间等因素对除铅效果的影响。结果表明，在废水ｐＨ４～１２、Ｐｂ２＋０～１００ｍｇ／Ｌ范围内，按铅／活化沸石重量比为１／２００投加活化沸石进行处理，铅去除率大于９８％。

The treatment of lead containing wastewater prepared in the laboratory has been tested with activated zeolite had a high capacity of removing lead,with the efficiency coming up to more than 98%,under the conditions of 4～12 of pH,0～100mg/L of lead,1/200 of lead/activated zeolite.This method is simple and low cost,providing a new way for the treatment of lead containing wastewater.
