摘　　要：通过小试试验探讨了臭氧—生物活性炭纤维去除微污染源水中氮的变化规律。结果表明,当反应器进水氨氮浓度较低时,会出现氨氮累积现象,BACF柱适应环境的能力较BAC柱强;臭氧化工艺对亚硝酸盐氮有较强的去除能力;当反应器中亚硝化杆菌和硝化杆菌生长成熟后,炭滤柱出水中均未检出亚硝酸盐氮;2种工艺对总氮的去除率均在10%以内,但03-BACF工艺去除氮的效率稍高于03-BAC工艺。The changing law of nitrogen in slightly polluted water source treated by ozone-biological activated carbon fiber was studied through pilot test. The results showed that ammonia nitrogen accumulation phenomenon appeared when ammonia nitrogen concn. Of influent was low. The adaptability of BACF column to environment was better than that of BAC column. The ozouation process had stronger removal ability on nitrite nitrogen. When nitrite microbe and nitrate microbe in reactor matured, the nitrite nitrogen in effluent from column could not be detected out. The removal rates of 2 kinds of processes on total nitrogen were all within 10% and the remeval efficiency of O3-BACF process on nitrogen was slightly higher than that of O3-BAC process.
