摘要
本文采用复合垂直流人工湿地进行了生活污水中磷的去除效果试验研究。试验结果表明,在水力负荷为222 mm/d的条件下,总磷的去除率可高达80%以上,而且去除效果随水力负荷的降低而增加,总磷的去除主要发生在下行流池中,而在上行流池中存在磷的释放现象;温度和溶解氧对磷的去除效果影响不显著。
The integrated vetical flow constructed wetland was applied to study the phosphorous removal from sewage.The results showed that in the condition of 222 mm/d,the total phosphorous removal efficiency is 80%,and the removal efficiceny increases with the decrease of hydraulic loading.In the wetland system,the removal of phosphorous mainly occurred in the down flow wetland,and the phosphorous released from the up flow wetland.The influence of temperature and dissovled oxygen to the phosphorous removal is not obvious.
