摘要
同步硝化反硝化(SND)是目前国内外污水脱氮技术研究领域的新热点。基于其高效低能耗特性,从宏观环境理论、微环境理论和生物学理论方面探讨同步硝化反硝化的脱氮机理,分析有机碳源、溶解氧、活性污泥絮体结构和pH值等因素对同步硝化反硝化所产生的影响。提出有待进一步解决的问题及深入研究的技术,从而达到节能降耗并提高工艺稳定性的目的。
The synchronous nitrification and denitrification is new hot point for field of polluted water denitrogen technology research.The denitrogen mechanism of synchronous nitrification and denitrification are discussed from the aspects of macro-environment theory,micro-environment theory and biological theory,based on characteristics of high efficiency and low energy consumption.
