摘要
反硝化过程中的亚硝酸盐(NO2--N)积累不但会对人体健康产生严重威胁,而且会对生物水处理工艺的正常运行造成破坏,因此对温度、溶解氧、碳源类型、pH值、硝酸盐、C/N比以及微生物种群组成等影响NO2--N积累的因素进行了分析,并对亚硝酸盐积累的原理进行了研究和探讨。
Nitrite （NO2--N） accumulation during denitrification not only do harm to the health of human being but also may damage the water treatment process. Influencing factors of nitrite accumulation during denitrification are analyzed, including temperature, dissolved oxygen, carbon source, pH, nitrate, C/N Ratio and the composition of the microbial community. The principle of nitrite accumulation during denitrification is also discussed.
