摘　　要：试验结果表明组合基质人工湿地在水力负荷较小时表现出较高的有机物和氮磷去除效率,当水力负荷提高后去除率明显降低,而煤渣基质人工湿地在低水力负荷时去除率相对较低,但对水力负荷的变化有较好的抗冲击能力。人工湿地的前端对有机物去除的贡献率在50%以上。The study indicated that the removal efficiency of organics,nitrogen and phosphorus in composite constructed wetland was higher under a lower hydraulic loading,and the removal efficiency reduced obviously when the hydraulic loading was increased.In cindery substrate constructed wetland,the removal efficiency of organics,nitrogen and phosphorus was comparative lower when operating under the lower hydraulic loading,which was not influenced deeply by the changing of hydraulic loading.More than 50% of organics can be removed in the front of the constructed wetland.
