不同植物对生活污水中氮、磷的去除效果研究

采用简易材料制作生态浮床系统,研究风车草、观音竹、红龙草、水芙蓉等4种植物对水体中总磷、溶解性磷、总氮、氨氮等指标的吸收情况。结果表明:当污水的总磷、溶解性磷、总氮分别为3.24—12.32、2.71~10.00、14.65~62.51mg/L时,在3-12d内,红龙草、风车草、水芙蓉、观音竹对总磷的平均去除率分别为94%、82.03%、75.11%、74%;对溶解性磷的的平均去除率分别为84.24%、78.94%、78.66%、78.14%;对总氮的平均去除率分别为86.6%、75.9%、74.8%、71.1%。红龙草对氮、磷的去除效果较好,其次是风车草、水芙蓉,观音竹的去除效果最差。...

ecological floating bed; nitrogen; phosphorus; removal rates
Using A ltemanthera ficoidea cv."Ruliginosa" Limnophila aromatica(Lam.) Merr. Bambusa multiplex cv. Fernleaf and Cyperus alternifolius as ecological floating bed plants to absorpt phosphorus and nitrogen in sewage. Total phosphorus (TP),soluble phosphorus, total Nitrogen (TN) in test sewage were 3.24-12.32 mg/L, 2.71-10.00 mg/L, 14.65-62.51mg/L respectively,the testing time were 3-12 days.The average removal rates of TP in test sewage by Altemanthera Ficoidea cv."Ruliginosa", Cyperus alternifolius, Limnophila aromatica (Lam.) Merr. Bambusa multiplex cv. Fernleaf. were 94%, 82.03%, 75.11%, 74% respectively;The average removal rates of soluble phosphorus in test swage were 84.24%, 78.94%, 78.66% and 78.14% respectively; and the average removal rates of TN w
