本研究以竹炭和砾石为组合填料,开展了水平潜流人工湿地和垂直流人工湿地对生活污水净化效果的比较研究。结果表明,水平潜流人工湿地对生活污水中COD、总氮和总磷的平均去除率分别为72.2%、47.8%和59.8%,垂直流人工湿地分别为75.0%、48.1%和58.2%。两种人工湿地中COD去除率均随水力停留时间(HRT)的增加而提高,而总氮和总磷去除率分别在HRT=3.5 d和HRT=2 d最高。不同人工湿地中细菌数量为水平潜流湿地稍高于垂直流湿地,根区高于非根区,而真菌数量则相反,且细菌和真菌的数量均随着HRT的增加而增加。
本研究以竹炭和礫石為組閤填料,開展瞭水平潛流人工濕地和垂直流人工濕地對生活汙水淨化效果的比較研究。結果錶明,水平潛流人工濕地對生活汙水中COD、總氮和總燐的平均去除率分彆為72.2%、47.8%和59.8%,垂直流人工濕地分彆為75.0%、48.1%和58.2%。兩種人工濕地中COD去除率均隨水力停留時間(HRT)的增加而提高,而總氮和總燐去除率分彆在HRT=3.5 d和HRT=2 d最高。不同人工濕地中細菌數量為水平潛流濕地稍高于垂直流濕地,根區高于非根區,而真菌數量則相反,且細菌和真菌的數量均隨著HRT的增加而增加。

A small-scale experiment was conducted to compare the domestic sewage purification effects for horizontal subsurface and vertical flow constructed wetlands with bamboo charcoal and gravel fillers. The results showed that the sewage COD, total nitrogen (TN) and total phosphorus (TP) removal rate of horizontal subsurface flow constructed wetland was 72.2%, 47.8%and 59.8%, respectively, while 75.0%, 48.1%and 58.2%for vertical one, respectively. The COD removal rate was increased with increase of hydraulic retention time (HRT), while the TN and TP removal rate was highest at 3.5d and 2d HRT, respectively, in two different constructed wetlands. The bacteria number was slightly higher in horizontal subsurface flow wetland or rhizosphere than that in vertical flow wetland or non-rhizosphere, while the fungi number was opposite. And the number of bacteria and fungi was increased with increase of HRT in two different constructed wetlands.
