城市径流水质已经成为农业面源污染的主要来源之一,根据武汉市径流的水质和水量特征,采用多级串联的表面流人工湿地系统对其进行了径流净化研究。对人工湿地不同运行阶段模拟径流的净化效果进行了对比,分析化学耗氧量COD_(Cr),生物耗氧量BOD_5,固态悬浮物SS,总氮TN,总磷TP,铵氮NH^+_4-N在湿地系统中的沿程变化,探讨人工湿地对城市径流污染的去除效应。结果表明:各指标在人工湿地中的去除效应大小依次为NH^+_4-N>COD_(Cr)>BOD_5>TN>SS>TP,其中对NH^+_4-N的去除效应显著高于其他指标的去除效应(p0.05)。通过对湿地系统沿程氮磷浓度衰减的拟合及回归分析,建立了与湿地系统进口浓度有关的COD_(Cr),BOD_5,SS,TN,TP,NH^+_4-N浓度的沿程衰减模型,相关分析表明其最佳的拟合模型均为指数衰减模型。该湿地系统在整个试验时期内均表现出了良好的净化效果,有效地减轻了城市径流水质对外界水环境的破坏,可用于城市地面径流污染的控制和利用,指数衰减模型的建立也为后续湿地设计及排水水质预测提供了理论分析依据。
