摘要
采用垂直流人工湿地工艺对模拟的水产养殖废水进行脱氮除磷等处理,并分析探讨该工艺的除污效率.结果表明:当预先在进水箱中进行曝气且气水体积比为1∶1、水力负荷为0.15m^3·(m^2·d)^(-1)、进水温度为10~20℃时,垂直流人工湿地对化学需氧量(chemical oxygen demand,COD)、氨氮、总氮和总磷的去除效果较好,去除率分别达到82.75%,83.68%,88.85%,84.72%,能够有效地处理水产养殖废水.
In order to achieve better nitrogen and phosphorus removal, vertical flow constructed wetland is used to treat aquaculture wastewater, and the decontamination efficiency is investi gated. Under the operating conditions (pre aeration (the ratio of air to water is 1 : 1), hydraulic load is 0.15 m^3 (m^2 · d) ^-1, water temperature is 15 ℃), the removal efficiencies of COD, NH4^+- N, TN and TP are 82.75%, 83.68%, 88.85% and 84. 72% respectively. This indicates that vertical flow constructed wetland can be applicable for the treatment of aquaculture,
