摘要
采用新型组合式人工湿地对湖北省宜昌市猇亭区污水处理厂的尾水进行了处理并进行了监测分析。运行结果表明,该套系统对废水中COD、SS、NH_4^+-N和TN平均去除率分别达53.6%、80.6%、85.1%和71.9%,其中,前端水平潜流人工湿地对污染物去除贡献率最大,湿地最终出水水质达到该工业园区的回用水水质标准。此外,对湿地中植物量的大小与污染物的去除效果进行了相关性分析,结果表明,湿地中植物生物量的大小与污染物的去除率并未有显著性相关关系。
The new hybrid constructed wetland was used for the treatment of tail-water from Xiaoting wastewater treatment plant of Yichang, Hubei province. The experimental results indicate that the average removal effieiencies of COD, SS, NH2--N, and TN were achieved 53.6%, 80.6%, 85.1%, and 71.9%, respectively. The horizontal subsur- face flow wetland made greatest contributions to the removal of all pollutants and the water quality of effluent reached the reuse water quality standard of industrial park. The correlations between plant biomass and the removal efficiencies of pollutants were analyzed and the results showed that there were no significant correlations between them.
