| 摘 要： | 提出了一种改进型波形潜流人工湿地(improved wavy subsurface flow constructed wetland,IW-SFCW)并研究了该湿地系统在5个水力停留时间(hydraulic retention time,HRT)(2、3、4、6和8 d)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4 d,进水COD、TN、NH4+-N和TP浓度分别为511、120、110和10 mg/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=8 d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=4 d时去除率最高,分别为54.4%和70.1%。

| Abstract: | An improved wavy subsurface flow constructed wetland(IW-SFCW) was proposed. The effect of this wetland system on the treatment of swine wastewater in five hydraulic retention time(HRT) was studied. The results showed that: COD, TP, TN and NH4+-N of swine wastewater can be removed well with this system.In the HRT 4 d, influent COD, TN, NH4 +-N, TP concentrations were 511 mg/L, 120 mg/L, 110 mg/L, 10 mg/L or so, the removal efficiencies of COD, NH4+-N, TN and TP were 86.0%, 54.4%, 70.1% and 91.6%, respectively. Besides, the removal efficiency of COD and TP improved gradually with the HRT extension. In the best adapt HRT 8 d,the removal efficiencies of COD and TP reached 92.7% and 96.8%, respectively. But the removal efficiency of TN and NH4+-N increased firstly and then decreased with the HRT extension. In the best adapt HRT 4 d, the removal efficiencies of TN and NH4+-N in the wetland system were 54.4% and 70.1%, respectively. |
