摘　　要：本研究设计一套表面流—水平潜流—垂直潜流复合人工湿地系统,探究不同浓度污水的总磷和总氮在湿地中的去除效率。2021年11月—12月的监测结果显示,本湿地系统处理含总氮46.12 mg/L和总磷29.63 mg/L的低浓度污水时,总氮去除率达80%以上,总磷达96%以上,出水基本达标,湿地的脱氮除磷效果良好。当处理含总氮67.72 mg/L和总磷88.17 mg/L的高浓度污水时,总氮和总磷的去除率分别达60%和36%以上,总氮出水达标,但除磷效果一般。冬季低温和含磷浓度过高会显著降低处理效果。A composite constructed wetlands system which included surface flow wetland,horizontal subsurface-flow wetland and vertical subsurface-flow wetland was designed to removal total phosphorus and total nitrogen in different wastewater.The wetland system was operated from November to December,2021.The results showed that the removal rate of total nitrogen and total phosphorus is up to 80%and 96%,respectively,when low concentration wastewater(total nitrogen 46.12 mg/L and total phosphorus 29.63 mg/L)is treated.When wetlands were added with high concentration(total nitrogen 67.72 mg/L and total phosphorus 88.17 mg/L)of wastewater,the removal rate of total nitrogen is large than 60%and total phosphorus is 36%on average.The nitrogen removal of this wetland system is quite effectiveness for both high and low concentration nitrogen in wastewater,but the removal rate of high concentration phosphorus in wastewater is mild.In addition,low temperature and high phosphorus content would significantly reduce the removal rate of phosphorus in constructed wetland.
