摘　　要：采用水平-沸石潜流湿地污水处理厂二级出水进行深度处理研究。控制水力负荷分别为0.278、0.139、0.093m3/(m.2d)时取水,分析其污水处理效果。结果表明,在不同的水力负荷条件下,水平-沸石潜流湿地对污水中的COD、NH3-N、TN和TP均表现出了较好的去除效果;确定了0.093 m3/(m2.d)为优化运行水力负荷;而且,该潜流湿地表现出了随着水力负荷的逐渐减小,其对各污染物的去除率逐渐提高的性质。Horizontal zeolite subsurface wetland was applied to advanced remove secondary effluent from sewage treatment plant. Sampling under hydraulic loadings were of 0.278, 0.139, 0.093 m3/. （m2·d）, respectively. The results show that, under different hydraulic loading conditions, the horizontal zeolite subsurface wetland shows better removal effect on COD, NHa-N, TN and TP, and the best run hydraulic loading rate is 0.093 m3/（m2· d）. In addition, this subsurface wetland manifested that the removal rates of contamination was gradually increased with decreasing the hydraulic load.
