摘要: Abstract The high removal efficiencies of traditional biological aniline-degrading systems always lead to accumulation ammonium. In this study, simultaneous aniline, nitrogen and phosphorus in a single sequencing batch reactor was achieved by using anaerobic/aerobic/anoxic (A/O/A) operational process. COD, NH 4 + -N, TN, TP were over 95.80%, 83.03%, 87.13%, 90.95%, respectively most cases with 250 mg L −1 initial aniline at 6 h cycle when DO 5.5 ± 0.5 mg L . Aniline able be completely degraded concentrations less than 750 mg L When increased, the rate -N slightly increased along moderate decrease TN. variation HRT had obvious influence on performance pollutants. system showed COD nutrients during operating conditions, which might contribute disposal aniline-rich industrial wastewater.
