摘要
低温废水普遍存在,生物脱氮工艺对温度变化敏感,低温将会影响脱氮效率。概述了低温对硝化工艺、反硝化工艺以及厌氧氨氧化工艺的影响,并重点探讨了在低温下保持较高脱氮效率的应对策略,主要包括菌种流加、接种耐冷菌、生物固定化、驯化等。
Low temperature wastewater exists widely. Biological denitrification process is sensitive to temperature changes. The effects of low temperature on nitrification, denitrification and anaerobic ammonia oxidation processes are summarized. The countermeasures for keeping denitrificaton efficiency at low temperature are discussed emphatically, mainly including sequential biocatalyst addition, and acclimation. seeding with psychrotrophs,biological immobilization,
