Abstract

Abstract:

The effect of reflux time on treatment efficiency of the intermittent anaerobic-aerobic reactor has been studied. The results show that reflux does not have obvious influence on nitrifying process. Under three kinds of conditions, all of the removing rates of NH₄⁺-N can be higher than 98%. However, if the reflux times are not many, the denitrification process is easy to be affected by the effluent loading. Increasing reflux time is good for denitrification electronic objects(NO₃^--N) deoxidizing to transfer, and make use of the organisms in influent completely for the denitrification process, so as to the denitrification rate. At the same time, the denitrification speed has increased with the increase of reflux times.

Key words: reflux, anaerobic, aerobic, denitrification rate

摘要：

研究了回流次数对间歇厌氧-好氧反应器处理效果的影响。结果表明,回流对硝化过程没有明显影响,3种条件下NH₄⁺-N去除率均能达98%以上。而在回流次数较少的情况下,反硝化过程易受进水负荷的影响。增加回流次数有利于反硝化电子受体(NO₃^--N)的转移,并充分利用进水中的有机物进行反硝化过程,提高脱氮率。同时,反硝化速率也随回流次数的增加而增加。
