摘 要: 以黄铁矿烧渣为吸附材料,分别对广东云浮某硫酸厂和采矿区外排含铊废水的净化处理进行初步研究。结果表明,由于在两种含铊废水中其他重金属的含量有所不同,故黄铁矿烧渣对其中铊废水的处理效果也不同。通过调节体系的pH值,Pb、Cd、Zn、Mn和Fe等大多数重金属能被烧渣有效吸附沉淀。采用该方法可有效控制工业废水铊污染的源头,且经济简捷。 Tl-bearing wastewaters from a sulfuric acid plant and a pyrite mining area were purified by using pyrite slag as adsorbent. The results show that T1 removing effects by pyrite slag are different, due to the varying contents of heavy metals besides thallium in the wastewaters. However, most heavy metals (Pb, Cd, Zn, Mn and Fe) in the wastewater can be effectively adsorbed and subsided by the pyrite slags through pH adjustment. This is a simple, economical and effective method to control T1 pollution in the source area.
