摘要
采用漂浮栽培美人蕉、蕹菜、水稻、野生稻等４种植物进行了处理化粪池废水的静态试验。结果表明，废水中ＣＯＤ、ＢＯＤ５、总氮、总磷等污染物得到较好的净化，污染物去除率明显高于对照。４种植物的净化能力和净化效果综合评价结果为美人蕉＞蕹菜＞水稻＞野生稻，美人蕉。
Static experiment of septic tank wastewater treatment have been carried out by adopting florating soilless culture of Garden Canna ( Canna generalis ), Swamp morningglory ( Iponoea aquatica ), Rice ( Oryza sativa ) and Wild Rice ( O. sativa ). The results showed that the COD, BOD 5 , TN and TP removal rates of the four plant treatments were all higher than that of the control. The results of an integrated assessment on the purification efficiency of the four plant species on the bases of purification capacity, lodging resistance, management, comprehensive utilization and landscape indicated that the purification efficiency of Garden Canna ranked the first followed by Swamp morningglory, rice and wild rice.
