摘　　要：针对缺水地区污染性城市河流的治理,采用河流附近材质,组建4组不同的人工湿地系统:芦苇碎石水平潜流湿地(H-1)、碎石水平潜流湿地(H-2)、芦苇碎石垂直潜流湿地(V-1)、芦苇炉渣垂直潜流湿地(V-2),对河流污染物进行处理研究。结果表明,通过H-1与H-2系统来考察植物对污染物去除贡献的比较,植物有一定的强化作用;基质填料不同V-2与V-1系统的比较,炉渣比碎石更为适宜作为人工湿地基质填料;湿地类型不同的V-1与H-1的比较,垂直潜流湿地更适宜作为处理污染性城市河流的湿地类型。综合分析得选用种植植物,以炉渣为基质的垂直潜流湿地作为处理污染性河流污水的最优人工湿地工艺技术。In order to study the pollutants removal efficiencies in different constructed wetlands for treatment of polluted fiver water in the water-shortage cities, four different constructed wetlands systems, reed gravel horizontal subsurface-flow constructed wetland （H-l）, gravel horizontal subsurface-flow constructed wetland （H-2）, reed gravel vertical-flow constructed wetland （V-1）, and reed slag vertical-flow constructed wetland （V-2）, were built according to the material near the river. All the four type of systems were applied to treat the polluted river water. The study results showed that plants played a strengthening role in contaminant removal mechanism through the contrast of contaminant removal rate by H-1 and H-2. Compared V-2 with V-1, which had different substrates, slag was better than gravel as substrate. Compared V-1 with H-1, results showed that vertical-flow constructed wetland was better than horizontal subsurface-flow constructed wetland. Through comprehensive analysis, plant slag vertical-flow constructed wetland was optimization constructed wetland process to treat polluted river water.
