摘　　要： 研究了以宽叶香蒲(Typha latifolia)为优势群落的净化塘系统来处理广东韶关凡口铅/锌矿选矿废水。经5年多的监测结果表明,该系统能有效地净化铅/锌石广废水。在进入净化塘系统前,未处理的废水合有高浓度的悬浮物(4 635mg/L)和重金属[Fb(1.61mg/L)、Zn(1.96mg/L)和Cd(0.022mg/L)]等,经过净化后,水质明显改善,pH从8.03下降到7.74,总悬浮物去除率达99％,Pb去除率为90％,Zn和Cd去除率为84％,其它重金属如Cu、Fe和Al等也都有不同程度的降低。 The results show that Pb/Zn mine wastewater can be effectively purified by the system. Before entering the system, the untreated wastewater contains rather high concentration of total suspended substance (4 635mg/L), Pb (1.61mg/L), Zn (1.96mg/L) and Ca(0.022mg/L), its pH is 8.03. After passing through the system, the water quality is obviously improved, with pH dropping to 7.74, suspended substance reduced by 99%, Pb by 90%, Zn by 84% and Cd by 84%; other heavy metals such as Cu,Fe, Al etc.are reduced in different degrees.
