| 摘 要： | 在HRT为4 d并进行微曝气及添加除磷材料的条件下，对复合人工湿地系统的降解过程进行了研究。结果表明，添加除磷材料后，系统最终出水比未添加除磷材料时对TP的去除率平均提高了约8.36%；TN浓度沿流程呈下降趋势， NH +4-N浓度除在水解池出水处升高外，其余均保持与TN浓度相同的沿程下降趋势； CODCr也沿程逐渐下降，湿地第一段和第二段对CODCr的去除起着主要作用，累计去除率约占系统总去除量的72.78%。

| Abstract: | Under the conditions that HRT is 4d without any measures to strengthen the system, after adding enhanced phosphorus removal materials,the system effluent TP removal efficiency increased by an average of about 8.36%; he system total nitrogen concentration with the flow direction of the wetlands has shown a downward trend, the concentration of ammonia nitrogen in the system in addition to hydrolysis at the second point is the point to increase the pool of water , the rest remain the same as the concentration of TN system flow direction showing a downward trend; the concentration of organic matter in sewage along the flow direction showing adecreasing trend, the first and the second paragraph of wetlands plays a major role to removal the concentration of organic matter, in addition to amount of 72.78% removal of total organic matter concentration. |
