环境污染和水体富营养化问题的尖锐化迫使越来越多的国家和地区制定严格的氮磷排放标准,这也使污水脱氮除磷技术一度成为污水处理领域的热点和难点.因此,研究和开发高效、经济的生物脱氮除磷工艺成为当前城市污水处理技术研究的热点.为遏制水体富营养化的恶化 ,氮、磷的排放标准日趋严格 ,生物脱氮除磷工艺能有效地去除水体中的氮、磷.通过对现有的生物脱氮除磷传统工艺和新近发展工艺的介绍和分析 ,指出经济、高效、低能耗是其发展的方向.同时认为今后应加强对生物脱氮除磷机理更深入的研究 ,大力开发技术成熟、高效经济又符合我国国情的新工艺

Answer 1

Environmental pollution and eutrophication of acute forced a growing number of countries and regions stringent emission standards for nitrogen and phosphorus,which sewage removal was once the sewage field hotspots and difficulties.Therefore,the research and development of effective,affordable biological nitrogen and phosphorus becomes the current study on urban waste water treatment technology.To suppress the eutrophication of deterioration,nitrogen and phosphorus emission standards are more stringent,biological nitrogen and phosphorus can effectively removal of nitrogen and phosphorus.Through biological nitrogen and phosphorus in traditional crafts and recent development process of the introduction and analysis,pointed out that the economical,efficient,low-power is its development.At the same time that should enhance biological nutrient removal mechanism more in-depth research,developing technologies mature,efficient economy and China's new technology
