摘　　要：采用好氧活性污泥与曝气生物滤池(BAF)联合工艺去除活性艳红X-3B厌氧中间产物苯胺类化合物。结果表明,经过活性污泥HRT=12h与曝气生物滤池HRT=4 h的连续降解,能将厌氧产生的苯胺彻底去除;进水ρ(苯胺)>6mg/L时开始对苯胺降解菌产生毒害作用,而进水COD>800 mg/L时,苯胺对降解酶竞争处于劣势,均会对苯胺的降解产生不利影响。对苯胺活性污泥降解进行动力学模拟,得到拟合性较好的一级反应动力学方程;用GC-MS分析得出苯胺被好氧微生物氧化生成苯酚,并进一步降解为烃类、醇类、脂类化合物以及CH4、CO2、H2O的终产物。The combined process of aerobic activated sludge and BAF was used to remove reactive red X-3B anaerobic intermediates of aniline. The results showed that after continuous degradation by aerobic activated sludge with HRT=12 h and BAF with HRT=4 h, aniline could be degraded completely; initial concentration aniline of 6 mg/L above was toxic to aniline degradation bacteria, and aniline had a competitive disadvantage in degrading enzymes when organics concentration was 800 mg/L above, both of which would adversely affect the degradation of aniline. Dynamics simulation of aniline activated sludge degradation would get fitting well with first order kinetics equation. Analyzing from GC-MS, aniline was oxidized to phenol, and further decomposed to hydrocarbons, alcohols, lipids compound and CH4, CO2, H2O by aerobic microorganisms.
