人工湿地净化富营养化河水试验研究(1)——植物对氮磷污染物的净化作用
Experimental Study on Eutrophicated River Purification by Man-made Wetlands in Pilot-scale(1)——Nitrogen and Phosphrus Removal by Plants
【摘要】 在对人工湿地及其在富营养化水质净化中的研究与应用的基础上,通过中试试验研究,得出如下结论：所选用的8种植物在湿地系统中均能较好生长,植物对湿地净化氮、磷污染物的贡献率分别为6．63%～23．08%和32．23%～82．85%。
【Abstract】 Study and application of constructed wetland in eutrophicated rivers and lakes were briefly discussed in this paper.The results of experiment of pilot-scale were also presented intensively,and found that all eight plant species could grow well in the man-made wetland system through observation and chlorophyll fluorescence analysis.Nitrogen and phosphrus removal efficiencies by plant uptake varied from 6.63%～23.08% and 32.23%～82.85% respectively.
