宽叶香蒲人工湿地对铅锌矿废水净化效能的研究
摘要: 研究以宽叶香蒲(Typha latifolia)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%、97.02%、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. Abstract: 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. 作 者: 作者单位: 期 刊: 深圳大学学报(理工版) ISTICEIPKU Journal: JOURNAL OF SHENZHEN UNIVERSITY SCIENCE & ENGINEERING 年,卷(期): 2000, 17(2) 分类号: X703 关键词: 宽叶香蒲 人工湿地 铅/锌矿废水 废水处理 Keywords: Typha latifolia man-made wetland mine wastewater purification【宽叶香蒲人工湿地对铅锌矿废水净化效能的研究】相关文章:
