摘要:
摘要 对单种和多种植物人工湿地对污水的净化效果和植物生长生物量进行了研究. 结果表明,两种湿地对有机物CODcr的净化效果差异不明显,但多种群落湿地对TP的净化效果优于单种群落湿地,而单种群落湿地对TN的净化效果又强于多种群落湿地.风车草在单种群落里生长旺盛,而在多种群落里生长稍差,单种群落的群落覆盖度明显高于多种群落的群落覆盖度;单种群落地上部分生物量为2 395.6 g/m2, 比多种群落的地上部分生物量多1倍强,而多种群落的地下部分生物量为688.0 g/m2,比单种群落的地下部分生物量多80%强;植物根系主要分布在0~5 cm表层,该层根系生物量占根系总生物量的60%强. 图1 表2 参12
Abstract:
Abstract The effect of monospecies and polyspecies constructed wetlands on wastewater urification and plant biomass increment was studied. The results indicated that purification efficiency of CODcr by monospecies wetland was almost the same as that by polyspecies wetland; the removal rate of TP by polyspecies wetland was higher than that by monospecies wetland, while the removal rate of TN by the former was lower than that by the latter. Cyperus alternifolius Linn. grew better in monospecies wetland with much higher community coverage than that in poly species wetland. The above-ground biomass in the monospecies wetland was more than that in the polyspecies wetland, but the underground biomass in the former was much less than that in the latter. In addition, the roots of the species mostly distributed in the layer of 0~5 cm, where more than 60% roots were found. Fig 1, Tab 2, Ref 12
