摘要
为了解季节变化对潜流人工湿地脱氮除磷效果的影响,以红砖作为基质、美人蕉作为湿地植物构建了潜流人工湿地,并对其不同季节的脱氮除磷效果进行了测定。结果表明:该人工湿地对NH4+-N和TP的去除效果随季节变化而变化,在夏季达到最高,二者均约为80%左右,冬季最低,其中NH4+-N去除率约为10%,TP去除率约为20%;NH4+-N和TP的去除率随季节变化由高到低的顺序均为夏季>秋季>春季>冬季。
In order to understand the effect of seasonal changes on purification efficiency of subsurface constructed wetland, a new constructed wetland is built with red brick as media and canna as plant, and then nitrogen and phosphorus removal efficiency is meas- ured. The results show that the removal efficiency of both NH＋-N and TP are very clear seasonal changes, both of their maximum values are about 80~ in summer and minimum values are about 10~//00 and 20~ respectively in winter, and the sequence of seasonal average removal efficiency is summer^autumn）spring^winter.
