摘要
研究了狐尾藻、水蕴草、轮叶黑藻、长叶久冠和铜线草等水生植物吸收水体中N、P的能力。结果表明狐尾藻、水蕴草、轮叶黑藻和长叶久冠对水体中的氮磷有较强的去除能力,且植物对水体中氮磷的去除率与植物质量之间呈相关关系;同时狐尾藻、水蕴草、轮叶黑藻和长叶久冠均有较好的环境适应性,而铜线草的环境适应性较差。由此推断可以利用狐尾藻、水蕴草、轮叶黑藻和长叶久冠水生植物在生态塘污水处理系统中构建水生植物系统来处理生活污水。
Several hydrophytes named Myriophyllum Verticillatum, Elodea densa （Planch.） Casp. , Hydrilla Verticillata, Echinodorus Uruguayensis and Paspalum pospaloides（ Michx. ）Scribn were used to investigate the ability of removal of nitrogen and phosphor in the sewage. The results show that MyriophyUum Verticillatum, Elodea densa （Planch.） Casp. , Hydrilla Verticillata and Echinodorus Uruguayensis have a remarkable effect on removal of N and P, and the removal rates of hydrophytes on N and P have correlation to weight of hydrophytes. Myriophyllum Verticillatum, Elodea densa （Planch.） Casp., Hydrilla Verticillata and Echinodorus Uruguayensis have good environment adaptability, by which hydrophytes-based treatment system for ecological pond sewage treatment system can be constructed.
