摘    要:针对五里湖富营养化水体,在同等条件下开展了3种类型人工湿地处理效果的比较研究,试验采用现场中试规模,水力负荷为0.8 m3/(m2·d).结果表明,垂直流、潜流和表面流3种人工湿地对氨氮的平均去除率分别为33.2%、27.4%和14.1%;对总氮的平均去除率分别为52.3%、50.1%和19.2%;对总磷的平均去除率分别为58.8%、57.9%和26.3%;对锰酸盐指数的平均去除率分别为37.2%、38.3%和14.8%;对叶绿素a的平均去除率分别为86.9%、96.1%和55.3%.可见,垂直流人工湿地对氨氮、总氮和总磷的去除效果最好,潜流人工湿地对高锰酸盐指数和叶绿素a的去除效果最好,但垂直流和潜流人工湿地之间的差异较小,表面流人工湿地对各污染物的去除效果均远低于前两者.从出水水质稳定性来看,垂直流人工湿地出水水质最稳定,潜流次之,表面流最差.

关 键 词:垂直流人工湿地  潜流人工湿地  表面流人工湿地  五里湖  富营养化水体

Abstract:Comparison research of different constructed wetland types to treat lake Wulihu water was carried out. Under the condition of the loading rates 0.8 m3/(m2·d), the removal efficiencies of the vertical flow wetland(VFW), subsurface flow wetland(SFW) and free surface wetland(FSW) had the following results: To ammonia nitrogen (NH+4-N) the average removal rates were 33.2%, 27.4% and 14.1%, respectively; To total nitrogen (TN) the average removal rates were 52.3%, 50.1% and 19.2%, respectively; To total phosphorus (TP) the average removal rates were 58.8%, 57.9% and 26.3%, respectively; To permanganate index the average removal rates were 37.2%, 38.3% and 14.8%, respectively; To chlorophyll a (Chl-a) the average removal rates were 86.9%, 96.1% and 55.3%, respectively. Obviously, VFW and SFW are more effective than FSW at treating eutrophicated water such as Lake Wulihu which with characters of low organically pollution and with high nitrogen and phosphorus pollution, and the VFW is the most effective on the removal of NH+4-N, TN and TP. SFW is the most effective on the removal of permanganate index and Chl-a. The effluent stability of VFW is better than SFW, and the SFW is better than FSW.
Keywords:vertical flow wetland  subsurface flow wetland  free surface wetland  lake Wulihu  eutrophicated water
