Abstract:

提出了一种改进型波形潜流人工湿地(improvedwavysubsurfaceflowconstructedwetland,IW-SFCW)并研究了该湿地系统在5个水力停留时间(hydraulicretentiontime,HRT)(2、3、4、6和8d)下对猪场废水的处理效果。结果表明,该湿地系统对猪场废水中各污染物有较好的去除效果。在水力停留时间为4d,进水COD、TN、NH4+-N和TP浓度分别为511、120、110和10mg/L左右时,该湿地系统对COD、TN、NH4+-N和TP的去除率分别为86.0%、54.4%、70.1%和91.6%。此外,该湿地系统对废水中COD、TP的去除效率随水力停留时间的延长逐渐提高,在HRT=8d时去除效果最好,去除率分别达到92.7%和96.8%;但对TN、NH4+-N的去除率却随水力停留时间的延长出现先上升后下降的趋势,在HRT=4d时去除率最高,分别为54.4%和70.1%。
