摘　　要：对20LSBR生物反应器处理高氨氮废水的活性污泥菌相进行了初步研究,成功地分离出了硝化菌、反硝化菌和异养菌,测定了工艺过程中各种成分和活性污泥细菌浓度的变化,为进一步研究活性污泥的活性,提高SBR生物脱氮效率奠定了基础。The group of bacteria in active sludge for the treatment of high strength ammonia wastewater was studied in 20 L SBR reactor. Nitrifying bacteria, denitrifying bacteria and heterotrophic bacteria were separated with their morphology observed. The content of various constituents and the number of various bacteria in the denitrification process were measured. This study may be valuable for improving the activity of active sludge and the denitrification efficiency in SBR biodenitrification.
