摘要
反硝化过程是废水生物脱氮的关键,低温下废水生物处理的反硝化效率显著降低。本文从低温对微生物反硝化处理效果的影响、低温对反硝化微生物的影响机制以及低温下反硝化效果的强化策略等方面的研究展开综述,并提出了可能的研究方向,以期为微生物低温反硝化进一步的机理研究与技术强化提供参考。
Denitfification is the key process of biological removal of nitrogen of wastewater and temperature is an important factor influencing the biological nitrogen removal. , The denitfification efficiency significantly decreases at low temperature. In this article, the impact of low temperature on denitrification efficiency, the mechanism of low temperature effect on denitrifying microorganism and the intensifying measures of denitrificafion efficiency at low temperature were summarized. Besides, the possible research trend was also proposed, provided reference for further study of the impact mechanism and the technology enhancements.
