摘要
同步硝化反硝化工艺同传统的生物脱氮工艺相比,可以节省碳源,减少曝气量,降低设备运行费用等优点,具有很大的发展前途。文章结合国内外研究,从微环境理论、微生物学理论和中间产物理论方面对同步硝化反硝化的产生机理进行了综述,并分析了同步硝化反硝化的实现条件和影响因素。最终提出了目前同步硝化反硝化尚待研究解决的问题。
Compared with traditional biological nitrogen removal process,simultaneous nitrification and denitrification(SND)reduces not only the oxygen requirements for the oxidation,but also the amount of added organic matter for denitrification and the operating cost requirements. SND has the very big development in the wastewater treatment. Based on thedomestic and foreignresearches, this paper summarizes theproduction mechanism of SND from the microenvironment theory, the microbiology theory and the intermediary product theory. Then the paper analyzes realization conditionsand the influence factors of SND. Finally, the paper proposes present problemsof SND.
