摘    要:对5个典型人工湿地进行分析,结果表明:人工湿地对各水质指标的去除率分别为:SS为70%~80%,TN及NH3-N约为30%~50%,TP约为20%-40%,CODcr约为40%~50%;TN、NH3-N及TP去除率基本上是随着进水浓度的上升而逐渐下降。CODcr及SS则是随着进水浓度的下降而逐渐下降;人工湿地的TN削减量为28~33kg/d,NH3-N为5.3-7.34kg/d,TP为1.4~1.7kg/d,CODcr为250—320kg/a,SS为120~300kg/d;人工湿地的污染物表面负荷平均去除量TN为2.00g/m^2。d,NH3-N为0.53g/m^2·d,TP为2.32g/m^2·d,CODcr,为19.24g/m^2·d,SS为374.71g/m^2·d。

Abstract:The research results about five typical constructed wetlands show that : their removal rate of different water quality indicators are respectively : SS : 70 - 80%, TN and NH3 - N : 30 - 50%, TP : 20 - 40%, CODcr : 40 - 50%. The removal effect of TN, NH3 - N and TP is decreasing with the increasing influent concentration. It is an opposite situation for CODcr and SS. The pollution reduction of TN is 28 -33kg/d, NH3 -N 5.3 -7.34kg/ d, TP 1.4 - 1.7kg/d, cODcr 250 - 320kg/d and SS 120 - 300kg/d. The average reduction of surface pollution load of the constructed wetlands is respectively: TN 2.00g/m2 . d, NH3 - N 0. 53g/m2 . d, TP 2.32g/m2 . d, CODcr 19. 24g/m2 . d and SS 374.71g/m2 . d.
Keywords:plateau lake  constructed wetland  removal rate  reduction  pollution load  Yunnan
