不同湿地植物对污染水体的净化效果
|
摘要
依据实验所在地的气候条件和植物自身的生长习性,选取水芹、石菖蒲、香蒲为研究对象,设置室内模拟实验,研究不同湿地植物对污染水体的净化效果,分析不同湿地植物作用下水体NH_4~+-N、NO_3~--N、TN、TP的变化情况。结果表明,这3种湿地植物对NH_4~+-N、NO_3~--N、TN、TP均有良好的去除效果,均能显著改善污染水体水质。综合分析各项指标发现,3种植物中石菖蒲对富营养化水体的净化效果最好。
Oenanthe javanica,acorus calamus and typha orientalis have been selected as target plants,according to the local climatic conditions and growth habits of plants,and the indoor simulated experiments implemented for investigating the purifying effect of different wetland plants on polluted water bodies,and analyzing the situation of changes of water body NH_4~+-N,NO_3~--N,TN and TP,under the effect of different wetland plants,The results indicate that all of the three kinds of wetland plants exhibite excellent removing effect on NH_4~+-N,NO_3~--N,TN and TP,and improve the water quality of polluted water. It is found through integrated analysis on every index that among the three kinds of plants,the purifying effect of acorus calamus on eutrophic water body is the best.
