摘　　要：为了探讨不同水力条件和挺水植物布设方式对复合垂直流人工湿地污染物去除效率的影响,搭建人工湿地中试,采用单因素实验法,研究不同条件下水体中有机物、氮、磷的净化规律。结果表明:在表面积一定的前提下,进水流量较小、水深较深,脱氮除磷效果较好;有机物去除效率随着水力停留时间的增加呈现先减小后增大的趋势。综合工况条件复合垂直流人工湿地在进水流量为200 L/(m^(2)·d),水力停留时间为72 h,水深为1.5 m的条件时有机物、氨氮、总磷的去除效率可达到69.20%、73.68%、90.64%,出水水质达到《地表水环境质量标准》(GB 3838-2022)中Ⅲ类水标准。该条件下,千屈菜和芦苇的种植布设方式采用10株/m 2和6株/m 2时去除效率较高。This paper sets up a pilot test of constructed wetland in order to explore the effects of different hydraulic conditions and the planting density of water protrusion plants on the pollutant removal efficiency of complex vertical flow constructed wetland.The single factor experiment method was used to clarify the purification law of organic matter,nitrogen and phosphorus in water under different conditions.The results show that the effect of nitrogen and phosphorus removal is better under the condition that the surface area is fixed,the influent flow rate is smaller and the water depth is deeper.With the increase of hydraulic retention time,the removal efficiency of organic matter first decreases and then increases.The removal efficiency of organic matter,ammonia nitrogen and total phosphorus can reach 69.20%,73.68%and 90.64%under the conditions of influent flow of 200 L/(m^(2)·d),hydraulic retention time of 72 h and water depth of 1.5 m.The effluent water quality meets the ClassⅢwater standard in GB3838-2022.Under these conditions,the removal efficiency was higher when 10 plants/m 2 and 6 plants/m 2 were adopted.
