摘要
在人工模拟条件下,利用室内试验箱培育,研究了挺水植物芦苇、慈姑和浮叶植物睡莲、荇菜对人工配置污水的净化效果。结果表明,4种水生植物均能有效吸收污水中过剩的氮、磷营养物质,经过20d植物处理,对水体中氮素去除率表现为芦苇(77.25%)>慈姑(76.16%)>荇菜(75.13%)>睡莲(71.69%),对磷素去除率表现为芦苇(78.97%)>慈姑(75.76%)>荇菜(75.23%)>睡莲(73.09%);4种水生植物对污水中的氮磷去除效果均比较明显,在相同条件下脱氮除磷效果最好的是挺水植物芦苇。
In order to investigate hydrophytes role on the purification of pond effluent which was eutrophic,four hy-drophytes(Nymphaea alba,Sagittaria,Phragmites australis,Nymphoides peltatum)were grown and as a none plantto compare effectiveness of nutrient removal. It can be concluded that all the hydrophytes had a good performance onremoval nutrients from treated water rather than without hydrophytes. After growing the four hydrophytes 20 days,thetotal nitrogen(TN)was removed by P. australis(77.25%)Sagittaria(76.16%)〉O.Kuntze(75.13%)〉Nymphaea alba(71.69%). The total phosphorus(TP)was removed by P.australis(78.97%)Sagittaria(75.76%)〉O. Kuntze(75.23%)〉Nymphaea alba(73.09%);Four hydrophytes to remove the effect of nitrogen and phosphorus in the sew-age. For the four hydrophytes growing under the same condition P.australis was the most effective hydrophytes for TNand TP removal.
