| 摘 要： | 用煤灰渣人工土壤和风车草组成的垂直流人工湿地系统对化粪池出水中总磷和无机磷的去除率分别达到75 %— 92 %和 73%— 92 % ,其处理出水中总磷和无机磷浓度大部分低于 1mg/L ,达到了城市污水二级生化处理的二级排放标准。垂直流煤灰渣人工湿地系统对磷的去除作用主要有 :物理作用、化学吸附与沉淀作用和微生物同化作用以及植物摄取等作用 ,其对化粪池出水中总磷的去除率分别为 2 2 .8%、5 0 %— 6 5 %和 1%— 3%。

| Abstract: | The removal rates of total phosphorus (TP) and inorganic phosphorus (IP) were 75%-92% and 73%-92%, respectively by means of vertical-flow constructed wetlands composed of cinder slag and Cyperus alternifolius for treating septic tank effluent. The concentrations of TP and IP in the treated effluent of four columns were low than 1 mg/L, and met with the secondary level of secondary biological treatment plant discharge standard. The removal mechanisms of phosphorus by vertical-flow constructed wetland include: physical, adsorption and chemical precipitation and microorganism assimilation, and plant uptake. The removal rates of TP by means of these removal mechanisms were accounted for 22.8%, 50%-65% and 1%-3%, respectively. |
