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。

摘  要:
[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,HY 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.
