Effect of treating Pb/Zn mine wastewater with Typha latifolia purification pond system

Abstract

Abstract: 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 (4635mg/L), Pb (1.61mg/L), Zn (1.96mg/L) and Ca(0.022mg/L), its pHis 8.03. After passing through the system, the water quality is obviously improved, with pHdropping 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.

Key words: Typha latifolia, Purification pond system, Pb/Zn mine wastewater, Wastewater treatment
