摘　　要：目的使自来水厂出水达到最新生活饮用水水质标准,满足提高整体区域水体水质的综合要求.方法利用固定化硝化细菌颗粒流化床反应器,采用连续曝气方式运行,检测进出水水质变化.结果水力停留时间(HRT)在0.5~1.5 h内变化,进水氨氮质量浓度为7.6~1.6mg.L-1,出水氨氮质量浓度为0.9~0.3 mg.L-1.结论固定硝化菌颗粒流化床系统具有较强的抗水力负荷冲击的能力,在枯水期,出水氨氮质量浓度<0.9 mg.L-1,能够达到《生活饮用水水源水质标准》(CJ3020-1993)中规定的Ⅱ级氨氮质量浓度的要求;在丰水期,出水氨氮质量浓度<0.4 mg.L-1,满足《生活饮用水卫生标准》(GB5749-2006)氨氮的要求.To catch up the new standard of the effluent quality of waterworks and to meet the requirement of getting integrated regional water stream better. With a 24 h no-stop fluidized-bed reactor filled with immobilized granular nitrifying bacteria, the variation of properties of influent and effluent are examined. The results show that the effluent ammonia - nitrogen concentration ranges from 0. 9 to 0.3 mg·L^-1, while the influent ranges from 7.6 to 1.6 mg·L^-1 when HRT ranges from 0. 5 - 1.5 h. The conclusions come out that fluidized-bed reactor filled with immobilized granular nitrifying bacteria can bear the fluctuation of HRT. And that the effluent concentration can meet the Quality Standard of Raw Water Stream（ CJ3020-1993 ） during the dry season. While during the wet season, the effluent can meet the Sanitation Standard of Drinking Water （ GB5749-2006 ）.
