采用表面流—潜流—潜流串联人工湿地模式,对排入长沙市青竹湖星月水库的污水进行处理。分别在2015年7月和11月,研究该人工湿地的水质和植物根际微生物数量。研究结果表明,在7月采样日,该人工湿地对污水中的化学需氧量、总氮、总磷和氨氮的去除率分别为81.9%、97.1%、96.0%和99.8%;在11月采样日,其去除率分别为85.7%、97.8%、96.4%和98.5%。在7月和11月采样日,各污染物含量大致上随着实验进程逐渐减小,在AII单元和AIII单元,污染物含量升高,原因是这两个单元兼顾溢洪的功能。在7月采样日,人工湿地对氨氮的去除率大于11月采样日,而在11月采样日,人工湿地对总氮、化学需氧量和总磷的去除率大于7月采...

Taking the Xingyue Reservoir of Qingzhu Lake in Changsha city as an example, we designed the sewage disposal of constructed wetlands under the mode of surface flow-subsurface flow-subsurface flow, and analyzed the water quality and the amount of rhizosphere microorganisms on sample days of July and on sample days of November of plant respectively. The results showed that the removal rates of chemical oxygen demand, total nitrogen, total phosphorus, ammonia nitrogen respectively were 81.9%, 97.1%, 96.0%, 99.8% on sample days of July, the removal rates respectively were 85.7%, 97.8%, 96.4%, 98.5...
