| 摘 要： | 本文通过一个小型复合流式和一个推流式人工湿地的设计及实验，监测了CODMn、NH3-N、N03^-N、N02^N等指标，比较了两种湿地对有机物的去除效果。结果表明，复合式人工湿地对CODMn、N03^-N的去除效果比推流式的好；而对NH3^-N的去除效果没有推流式的好；在两种湿地中增加污染负荷和延长水力停留时间都能增加污染物的去除率。

| Abstract: | The technology of constructing wetland has good disposal effect and low operation cost, which is a new technology in wastewater treatment. Some parameters, such as CODMn, NH3 - N, NO3 - N, NO2 - N, were measured within two - month operation of compound flow in constructing wetland and pushing flow in constructing wedand. The removal rate of organisms in both is also compared. It shows that the former of the efficiency of removing CODMn and NO2 - N is better, but the latter of that of removing NH3 - N is better; removal efficiency improved can be improved in both with increasing pollution load and hydraulic retention time. |
