| 摘 要： | 采用实验室模拟研究了以盐碱土壤为基质的不同湿地植物人工湿地系统以及对水中低质量浓度氮和磷的去除效率。实验表明，芦苇系统、香蒲系统、车钱草系统和无植物系统均对水中低质量浓度的N具有净化效果。3种植物系统相比，香蒲系统的净化效果较其他二者较佳，芦苇系统与车钱草的净化效果相当；同时实验也表明4种湿地系统对低质量浓度的P不具有净化效果，随着水力停留时间的增加，系统中的P质量浓度反而会有所增加。 |
| 关 键 词： | 盐碱土壤基质 人工湿地 氮 磷 |

| Abstract: | Removal efficiency of low nitrogen and phosphorus concentration in four constructed wetland systems with simulated bed of plants was studied. The experiments showed that the reed bed system, cattail bed system and Herba plantains bed system all had the ability to purify nitrogen. Among the 3 systems, the cattail bed system had the highest removal efficiency and the other two sys-tems were equivalent. At the same time, the experiment showed that the four bed systems had no ability to purify the phosphorus, and conversely, as the hydrological retention lasted, the concentration of phosphorus increased as well. |
