摘　　要：为解决人工湿地在冬春季节去污能力下降的问题,对人工湿地的布水方式进行了优化,探究了8种不同物候期水生植物在不同季节去除营养盐和COD的效率。研究结果表明,优化布水方案能促进8种植物的根系生长,有利于改善系统的去污能力。不同植物组成的人工湿地在不同季节的去污能力不同,同时在人工湿地中种植夏秋组和冬春组湿地植物,或许是解决人工湿地在冬春季节污染物去除率偏低这一问题的有效途径。In order to solve the problem of the decline of decontamination ability of constructed wetland in winter and spring,we optimized the water distribution of constructed wetland,and explored the nutrition-and-COD-removing efficiency of 8 species of aquatic plants that had different phenophases. The results showed that the optimized water distribution could promote the growth of the roots of all the 8 species,and could improve the decontamination ability of constructed wetland. Constructed wetland with different plants had different decontamination ability in different seasons. Planting plants of different phenophases together might be an effective way to solve the problem of the low decontamination efficiency of constructed wetland in winter and spring.
