摘要
研究以宽叶香蒲 (Typhalatifolia )为优势种的人工湿地系统对广东省韶关市凡口铅 /锌矿采矿废水净化效能 .研究结果表明 :宽叶香蒲人工湿地生态系统能有效地净化铅 /锌矿废水 .经系统处理后 ,COD、固体悬浮物、Pb、Zn、Cu和Cd的去除率分别为92 19%、 99 62 %、 93 98%、 97 0 2 %、 96 87%和 96 39% ,水质得到明显改善 .主要污染物TSS、Pb、Zn、Cu和Cd等均达到工业标准 ,并接近农灌标准 .
The efficiency of Typha latifolia Linn man made wetland to treat the wastewater from a Pb/Zn mine at Shaoguan, Guangdong Province, was evaluated by monitoring water quality. The results show that the Pb/Zn mine wastewater could be effectively purified by the man made wetland. After passing through the system,the water quality was obviously improved. The total suspended solids (TSS) reduced by 99 62%, COD by 92 19%,Pb by 93 98%,Zn by 97 02%,Cu by 96 87%,Cd by 96 39% respectively. With the restoration of wetland, the effectiveness of wetland on wastewater purification was also significantly improved.
