| 摘 要： | 以净化城市受污染河水为目标,对Living Machine系统进行改进而构建了植物浮床生态箱/植物浮床生态箱/人工湿地/沉水植物生态箱系统,在系统中引入了多种植物以及鱼类、螺蛳、虾等物种,并以间歇方式运行,平均水力停留时间为2 d.结果表明,经过该系统处理后河水的DO含量提高了100%,对NH4--N的去除率为82.4%,对TN的去除率为23.4%,对TP的去除率为50.2%,对COD的去除率为28.1%;出水DO、NH4+-N、TN、TP、COD分别为5.20、0.42、9.78、0.34、12.72 mg/L.

| Abstract: | A modified Living Machine system was constructed to investigate the purification of polluted urban river water.It consists of two planted floating beds,a constructed wetland and a submerged plant bed.Several kinds of plants,fishes,snails and shrimps are cultured in the system which is operated in sequencing batch mode with hydraulic retention time of 2 days.The results show that after the treatment of the system,DO in the river water is increased by 100%,and the removal rates of NH+4-N,TN,TP and COD are 82.... |
