摘要: 探讨了植物在人工湿地系统处理污水中的作用,并分析了影响植物生长的主要环境因素,结合实例分析了湿地植物吸收氮磷在不同生长期的变化和其在去除氮磷营养物中的贡献,认为通过秋冬季的植物收割去除的氮磷量比较低,植物可以作为冬季保温材料而不收割,提出通过组合技术来改善人工湿地氮磷去除能力的思路。

Abstract: In this paper,the functions of macrophyte in constructed wetland wastewater treatment system were approached,with the major environmental factors affecting macrophyte growth analyzed.The results showed that macrophyte during its growth period had different nitrogen and phosphorous assimilation,and the removal of nitrogen and phosphorous through harvesting in autumn or winter was rather low.It was considered that macrophyte should not be harvested but used as thermo-keeping material in cold winter.Some ideas of adopting integrated treating technologies were proposed to improve the removal efficiency of nitrogen and phosphorous in constructed wetlands.
