摘　　要：O3-BAC工艺运行多年后,活性炭滤池炭层厚度逐渐降低。对部分活性炭滤池补充颗粒活性炭,并分析了其与未补炭的活性炭滤池在实际生产运行中对氨氮和亚硝酸盐氮的去除效果。结果表明,两组活性炭滤池对氨氮的去除效果基本相同,但补炭的活性炭滤池对亚硝酸盐氮的去除效果略差。After years of operation of the O 3-BAC process,the thickness of carbon layer in activated carbon filters decreased gradually.Granular active carbon was supplemented to some filters,and the filter removal effects on ammonia nitrogen and nitrite nitrogen with and without carbon supplement were analyzed.The results showed that the two groups of filters had the same removal effect on ammonia nitrogen,but the removal effect on nitrite nitrogen by the filter with carbon supplement was slightly poor.
