| 摘 要： | 利用复合垂直流人工湿地对城镇污水厂尾水进行深度处理，研究了湿地系统对水中营养元素及微量雌激素的去除效果。结果表明：复合垂直流人工湿地对污水厂尾水具有良好的处理效果；水力负荷、填料种类、植物、季节等因素影响湿地处理效果。复合垂直流湿地系统对污染物的去除作用主要发生在下行池前1/6段，种植芦苇的沸石湿地系统处理效果最佳；在水力负荷为0.12 m3·（m2·d）-1时，运行良好的复合垂直流湿地出水水质指标达到《城市污水再生利用景观环境用水水质》标准（GB/T 18921-2002）。

| Abstract: | An integrated, vertical-flow constructed wetland was used for the advanced treatment of urban tailwater. The results indicate that nutrient elements and estrogens in the tailwater were efficiently removed by the constructed wetland. Removal efficiency was primarily determined by hydraulic loading rate, packing types, plant species, and season. Removal mainly occurred in the down-flow pool that comprised one-sixth of the constructed wetland. The highest removal efficiency was achieved in the zeolite wetland system with Phragmites australis. At a hydraulic loading rate of 0.12 m3·(m2·d)-1, the water quality index of wetland effluent met the standard for The Reuse of Urban Recycling Water-Water Quality Standard for Scenic Environment Use (GB/T 18921-2002). |
