摘要: 采用无土栽培美人蕉、蕹菜、水稻、野生稻处理生活废水.结果表明,静态试验中COD、T-N、T-P等污染物的平均去除率,4种植物处理比对照分别高出8.7~19.8%、20.3~66.6%、23.5~61.7%.4种植物对污染物的去除能力为美人蕉、蕹菜>水稻>野生稻.3级植物塘系统中污染物去除率分别为BOD2 9.7%、COD 71.1%、T-N 66.5%、T-P 60.7%,而人工土快滤与植物塘的复合系统中则为BOD5 83.9%、COD 79.3%、T-N 64.8%、T-P 40.9%.

Abstract: The study on the domestic wastewater treatnent with soilless cultivated Canna generalis, Iponoea aauatica, Oruza sativa and O.meyeriana subsp.granulata shows that in static experiment, the average removal rate of COD and total N and P is respectively 8.7 ~19.8, 20.3~66.6 and 23.5~67.1% higher than control. The removal capacity of these plants is in the order of Canna generalis and Iponoea aquatica > Oryza sativa > O.meyeriana subsp granulata. In third grade plant lagoon system, the removal rate of BOD5,COD and total N and P is respectively 79.7, 71.1, 66.5 and 60.7%; but in artificial rapid infiltration soil and plant lagoon system, it is 83.9, 79.3, 64.8 and 40.9% respectively.
