| 摘 要： | 在排放酸性重金属废水的铁矿排土场建设人工湿地处理系统,面积130m~2,废水流量0.5m~3/h,经过两个月的运行测试结果表明:人工湿地系统能有效地处理酸水.酸水pH值由2.6升高到6.1;铜离子由25.79×10~(-6)减少到0.099×10~(-6),去除率为99.7%;铁离子由36.50×10~(-6)降到0.031×10~(-6),去除率为99.8%;锰离子从393.6×10~(-6)降低到107.20×10~(-6),去除率为70.9%.

| Abstract: | A constructed wetland eco-system built on a waste stonepile in an iron mine which was used to drain acidic heavy metal wastewater with an area of 130 m2 and a wastewater discharge of 0.5m /h. Results of two months's operation and experiment showed that the constructed wetland eco-system could effectively trreat acidic wastewater. The pH value of acidic wastewater raised to 6.1 from 2.6; Cu ion reduced to 0.099 × 10-6 from 25.79 × 10-6 and the ratio of removal was 99.7% ;Fe ion reduced to 0.031 × 10 - 6 from 36.5 × 10-6 and the ratio of removal was 99.8 % ; Mn ion reduced to 107.26 × 10 -6 from 393.6 × 10 - 6 and the ratio of removal was 70.90 % . |
