摘要:内蒙古某城市污水处理厂主要处理工上游企业污水和生活污水,但由于上游企业出现生产事故,进水总氮负荷持续偏高,导致部分反硝化菌受抑制,出水总氮不达标。鉴于此情况该污水厂拟采用微生物增强技术恢复反硝化菌的活性快速恢复反硝化系统。本文阐述了通过投加生物倍活反硝化菌种以增强系统对总氮的去除能力。投加2d 后,出水总氮开始降低,4d 后出水总氮达到排放标准。
关键词:反硝化菌种;出水总氮;总氮负荷

Abstract:A municipal sewage treatment plant in Inner Mongolia mainly deals with the wastewater from upstream enterprises and domestic sewage. However, due to the production accidents of upstream enterprises, the total nitrogen load of the influent water is on the high side, which results in the inhibition of some denitrifying bacteria and the total nitrogen of the effluent water is not up to the standard.In view of this situation, the plant plans to adopt microbial enhancement technology to restore the activity of denitrifying bacteria and quickly restore the denitrification system.In order to enhance the removal ability of total nitrogen, this paper describes adding biological double active denitrifying bacteria. After adding 2 days, the total nitrogen of effluent began to decrease, and 4 days later, the total nitrogen of effluent reached the discharge standard.
Keywords:Denitrifying bacteria; effluent total nitrogen; total nitrogen load
