摘　　要：[目的]模拟静态人工湿地环境,移栽灌木柳,研究其对污水中氮元素的净化效率。[方法]在时效试验中设立半年栽组(HY组)、半月栽组(HM组)和无柳对照组(C组),在量效试验中设置3棵/箱组、6棵/箱组、9棵/箱组和无柳对照组,来检测污水浸入后氨氮、硝氮的变化趋势。[结果]时效试验中HY组效果最好,灌木柳扦插期越长,对氨氮的净化率越高。量效试验中6棵组和9棵组的净化率均达95%净化目标。[结论]最佳量效和最短时效分别为17棵/m2(6棵/箱)和1 d。[ Objective] To simulate static artificial wetland environment, transplant shrub willow, the purification efficiency on nitrogen in sewage was studied. [ Method] In aging test, setting half year group（ HY group）, half month group（ HM group） and blank control group（ C group）, in dose response test, setting 3 trees/box, 6 trees/box, 9 trees/box and blank control group, the variation trend of NO4-N and NO3- N was determined. [ Result] In aging test, FIY group has the best effect, the longer of shrub willow cottage period the NO4-N removal rate is higher. In dose response test, the purification rate of 6 trees/box, 9 trees/box can up to 95%. [ Conclusion] The best planting density was 17 trees/m2（6 tree/box） and the shortest purification time was one day.
