摘　　要：为探究新兴污染物PFBS是否会对活性污泥硝化脱氮系统的性能产生影响,通过构建短期序批式反应器(SBR),研究不同质量浓度条件下PFBS对该系统的影响。结果表明,一定量PFBS的存在会降低系统的氨氮去除率。PFBS质量浓度低于250 mg/L时,对生物脱氮效能的影响并不显著。当PFBS质量浓度达到250 mg/L时,对生物脱氮效能的影响程度急剧升高。PFBS的存在会降低氨氧化菌的生物活性,阻碍氨氮的转化,最终对活性污泥系统的脱氮效能产生一定的负面影响。In order to investigate whether the emerging pollutant PFBS affects the performance of the activated sludge nitrification and denitrification system,a short-term batch reactor(SBR)is constructed to investigate the effect of PFBS on this system under different mass concentration conditions.Results indicate that the presence of a certain amount of PFBS can reduce the removal rate of ammonia nitrogen.When the mass concentration of PFBS is less than 250 mg/L,no significant effect is shown on the biological nitrogen removal efficiency,whereas when the mass concentration of PFBS reaches 250 mg/L,the influence degree on the biological nitrogen removal efficiency increases sharply.Presence of PFBS reduces the biological activity of ammonia oxidising bacteria,hindering the conversion of ammonia nitrogen,and ultimately shows a certain negative effect on the the nitrogen removal efficiency of the activated sludge system.
