摘要
随着科技的发展,节能降耗的改良的脱氮除磷技术在国内外迅速发展。文章阐述了污水生物脱氮除磷的改良的技术,介绍了UCT技术、同步硝化反硝化、短程硝化反硝化、SBR改良工艺及CASS工艺等脱氮除磷技术,这些工艺运行灵活、费用低,解决因碳源不足、含NO2-或NO3-污泥回流等问题而影响脱氮除磷效果的新型技术,是今后污水脱氮除磷发展的方向。
With the development of science and technology, the improved nitrogen and phosphorus removal technology of saving energy and reducing consumption is developing rapidly at home and abroad. In this paper, the improved technologies of biological nitrogen and phosphorus removal from wastewater are introduced, such as UCT technology, simultaneous nitrification and denitrification,short-cut nitrification and denitrification, improved SBR process and CASS process. These processes are flexible in operation and low in cost, able to solve problems such as insufficient carbon source and NO2^- or NO3^- sludge backflow, which impact the effect of nitrogen and phosphorus removal, therefore it is the development direction of wastewater nitrogen and phosphorus removal in the future.
