摘要
生态除磷技术相比于化学法除磷、A2/O生物排泥除磷,不但廉价高效,还能将水体净化与环境景观美化结合起来,具有广阔的发展前景。综述了生态除磷技术中动植物吸收除磷、生物载体附着微生物群吸附除磷、厌氧与好氧相结合的微环境产磷化氢除磷3种除磷方式,及通过构建生态浮床强化富营养化水体生态除磷技术的研究现状。该研究成果对生态除磷工程的设计和调控具有指导意义。
Compared with chemical dephosphorization and A^2/O biological sludge discharge dephosphorization,ecological dephosphorization technology not only is cheap and efficient,but also combine the water body purification with environmental beautifying,thus it has broad development prospect.In this paper,three ecological dephosphorization technologies were introduced,namely,phosphorus absorption by animals and plants,phosphorus absorption by biological carrier attached microbes,and phosphorus removal by the phosphine produced from anaerobic and aerobic combined micro environment.Through building an ecological floating bed,the studies on the ecological dephosphorization technology of eutrophic water were further enhanced.The study results guided the design and reualtion of ecological dephosphorization engineering.
