%X 通过采用水生蔬菜水芹和豆瓣菜作为生态浮床栽培材料,对其净化富营养化水体的效果及其处理后的品质等方面进行研究.结果表明,水生蔬菜不仅能在富营养化水体中正常生长,还对富营养化水体有较强净化能力,且净化能力随着处理时间的延长而提高.处理20d,水芹对富营养化水体中的TN、NH4+-N、TP、CODMn、Chl.a的去除率分别达到76.86%、69.39%、90.45%、95.03%和89.81%;豆瓣菜对富营养化水体中的TN、NH4+-N、TP、CODMn、Chl.a的去除率分别达到78.27%、67.95%、89.98%、95.38%和91.28%.水芹和豆瓣菜不仅能显著改善富营养化水体的水质,且没有产生硝酸盐及重金属富集,符合食用标准;还能产生一定的经济效益.
%X Using water dropwort and watercress as the planting stuff on ecological floating beds, the purification effectiveness of eu-trophic
water and their characteristics were investigated. The results showed that aquatic vegetable not only could grow well in eu-trophic
water bodies, but also was able to purify the eutrophic water bodies effectively, and the purification ability increased treatment time. The removal rate of TN、NH4+-N、TP、CODMn,and Chl. a reached 76.86%, 69. 39%, 90.45%, 95.03%,89.81% by water dropwort for 20d treatment, respectively. In addition, the removal rate of TN、NH4+-N、TP、CODMn,and Chl.a reached 78.27%,67.95%,89.98%,95.38% and 91.28% by watercress for20d treatment, respectively. It was dropwort and watercress had a significant effect on improving the quality of the eutrophic ment of nitrate and heavy metals in plants, so water dropwort and watercress were edible proved that water nutrition enrich-water, without producing according to food standard and could pro-dace certain economic benefits.
