摘　　要：人工湿地中磷是通过基质、微生物和植物的共同作用击除的,其中基质对磷的吸附和沉淀是人工湿地除磷的主要方面。构筑两个以碎石和细砂为填料的人工湿地模拟单元,一个种上芦苇,另一个不种任何植物,研究湿地对磷的处理效果。前期试验表明,种芦苇的湿地总磷去除率可以达到92％,其中,总磷的67．35％在湿地上部就得以去除,有相当一部分磷是由湿地中植物、微生物和基质的协同作用加速去除的。最后对人工湿地除磷存在的主要问题及对策进行了探讨。Phosphorus is removed by the filler, microorganism and plant in wedand, the adsorb and precipitate of the filler are the main removal aspects of phosphorus. In order to research the removing effect of phosphorus in constructed wetland. We constructed two imitated unit with detritus and thin sand for filler, and one unit plant reed, another plant nothing. The experiment explained that the first unit can removal 92% of the total phosphorus ,67.35% of total phosphorus was removed depend on the upper filler, a lot of total phosphorus was removed by the conjunction of plant, microorganism and filler, which accelerated the remove speed of phosphorus. The main problem and counterplan of phosphorus removal in wedand are discussed at last.
