金边麦冬人工湿地对含铅废水的处理研究

Study on the effect of Phnom Penh Ophiopogon artificial wetlands on the treatment of lead-bearing wastewater

研究了以土壤为基质材料所构建的金边麦冬人工湿地对含铅废水的净化效率,并探讨了含铅废水的流量对铅去除效率的影响。实验结果表明:金边麦冬人工湿地对含铅废水中的铅具有较好的去除效果,在流量为3 L/d时,金边麦冬人工湿地对铅的去除率最高,可达到98.30%;在流量为18 L/d时,去除率仍可达到82.63%。

The influence of Phnom Penh Ophiopogon artificial wetland, which is based mainly on soil as its sub- strate material, on the purification efficiency has been studied. The influence of the flow rate of lead-bearing wastew- ater on the removing rate of lead has been discussed. The results show that the Phnom Penh Ophiopogon has pretty good lead removing effectiveness on lead-bearing wastewater. When the flow rate is 3 L/d,its lead removing rate is the highest, reaching 98.30%; while its flow rate is 18 L/d, the lead removing rate can still reach 82.63%.
