摘要：

SHARON工艺是一种用于处理高浓度、低碳氮质量比的含氨废水的新工艺,它利用亚硝酸细菌和硝酸细菌在不同条件下的生长速率的差异,通过调控温度、pH、溶解氧、水力停留时间等参数,实现短程硝化反硝化。与传统生物脱氮过程相比具有流程简单、脱氮速率快、投资和运行费用低等优点,同时给短程硝化反硝化的研究提供了一定的参考。

Abstract:

SHARON is a newprocess to treat rich ammonia wastewater with lowratio of C/N. According to the different growth rates of the nitrobacteria and nitrosomonas under different conditions, shortcut nitrification-denitrfication has been realized by adjusting the temperature, pH, dissolved oxygen and HRT. Compared with traditional process,the flowis simple, the cost of operation and investment of SHARON is pretty lowand denitrification speed is rapid. It provides definite reference to the shortcut nitrification-denitrfication.

Key words: nitrosation reactor, nitrogen removal, shortcut nitrification-denitrfication
