【摘要】 通过构建水耕生态系统来改善太湖水源地水质,中试实验结果表明:当停留时间为1d时能高效去除饮用水中污染物,还可以提高运行能力和效益。系统对TN、NH4+-N、NO3--N、NO2--N、TP、PO4--P的去除率最高可分别达89.85%、88.69%、82.64%、77.73%、90.65%、67.11%,对总有机物污染物的去除率可以达到54.92%。因此水耕生态系统对太湖水源地水质有明显的改善作用。更多还原

【Abstract】 Pilot test was made to improve water quality in Taihu Lake through the construction of hydroponic ecological system.The result shows that 24 hours of HRT has the highest removal rate and capacity and benefit.Under the condition,the system has the removal rates for TN,ammonia nitrogen,nitrate nitrogen,nitrite nitrogen,TP,phosphatic phosphor,chl a were 89.85%,88.69%,82.64%,77.73%,90.65% and 67.11%respectively.Removal rate for organic pollutant reached to 54.92%.It is evident that water quality in Taihu Lake can be significantly improved by the construction of hydroponic ecological system.更多还原
