对比研究了7种湿地植物对沼液中的化学需氧量（COD）、总氮（TN）和总磷（TP）的净化效果．结果表明，随着处理时间的延长，大多数植物对污染的去除效果呈现先增加后趋于平缓或降低的趋势，一般在7d时各植物对污染物的去除最好，其中单一植物红掌、万年青和白掌对沼液中污染物的去除效果较好；在植物组配试验中，对COD去除效果最好的组合是万年青和红掌，去除率达到78.62％，对T N和T P去除效果最好的是万年青、红掌和白掌组合，去除率分别达到75.54％和73.08％．

Seven wetland plants were chosen to study the purification effectiveness in biogas slurry by hy‐droponic method .Results showed that the pollutants removal rates for most plants were increasd with the hydraulic retention time increasing firstly ,and then remain stable or decreased .We could get better re‐moval efficiency when the hydraulic retention time was 7 d ,the purification effect in biogas slurry of Ro‐hdea japonica ,Spathiphyllum kochii and Anthurium andraeanum were significantly higher than others .The best removal rate for COD was the combination of Rohdea japonica and Anthurium andraeanum ,which can reach 78 .62% .And the best removal efficiency on TP and TN were both in the combination of Rohdea japonica , Anthurium andraeanum and Spathiphyllum kochii ,which can reach 75 .54% and 73 .08% ,respectively .
