摘要
研究炼油废水生化系统受到冲击后,投加硝化菌种快速恢复硝化系统NH_(3)-N去除效果的能力。结果表明:使用生物倍活硝化菌种后,出水NH_(3)-N平均浓度由25 mg/L降低至1 mg/L以内,保证生化系统出水稳定达标排放。同时生化系统中活性污泥絮体增大、结构紧密、微生物活性显著增强。
After impact appeared in the biochemical system for refinery wastewater treatment,usage of nitrifying bacteria to fast recovery of NH 3-N removal effect of the nitrification system was studied.The results showed that after adopting the polyploid nitrifying bacteria,the average concentration of NH_(3)-N in the effluent was reduced from 25 mg/L to less than 1 mg/L,which ensured the stable discharge up to standard of the effluent in biochemical system.At the same time,the activated sludge flocs in the biochemical system was enlarged,the structure was compact,and the microbial activity was significantly enhanced.
