| 摘 要： | 选取水烛、石菖蒲和黄菖蒲三种挺水植物作为无土栽培系统的培养物,通过动态试验进行农村生活污水处理对比研究。结果表明:相对对照系统,三种植物对农村生活污水均具有较好的适应性,生长量石菖蒲>黄菖蒲>水烛;处理系统对COD、NH+4-N和TN的去除效果依次为石菖蒲>黄菖蒲>水烛>对照;对TP的去除率依次为水烛>黄菖蒲>石菖蒲>对照。同时,通过对处理系统去除氮磷途径的分析,发现植物吸收作用是主要去除方式,沉淀吸附也起着重要的作用。综合三种植物的净化能力,认为石菖蒲更适合无土栽培处理系统。

| Abstract: | Typha augustifolia L.,Acorus calamus and Iris pseudacorus L.were chosen as main emerged plants in hydroponics system for the treatment of rural domestic wastewater.Results showed that removal efficiency of COD,NH4+-N and TN was ranked in the order of Acorus calamus,Iris pseudacorus Linn and Typha augustifolia L.,while the compositor was Typha augustifolia L.,Iris pseudacorus Linn and Acorus calamus for the removal efficiency of TP.It was found that plants absorption,biodegradation and sedimentation were sup... |
