SBBR系统中SND试验研究

Experimental study on SND in SBBR system

主要介绍序批式生物膜反应器及国内外研究情况,研究了在SBBR反应器中出现的同时硝化反硝化现象,针对SND现象的影响因素DO和C/N比进行了详细分析,试验得出结论如下:当溶解氧浓度在0.8~1.4mg/L时,碳/氮比在12~13范围时,能够取得较好的同步硝化反硝化效果。

This paper mainly introduces the sequencing batch biofilm reactor and the research situation at home and abroad, and studies the simultaneous nitrification and denitrification phenomenon in the SBBR reactor. The DO and C/N ratios of the SND phenomenon are analyzed in detail. The conclusions are as follows： When the dissolved oxygen concentration is 0.8-1.4 mg/L, the carbon/nitrogen ratio is in the range of 12-13, and the better simultaneous nitrification and denitrification effect can be obtained.
