%X The mixed wastewater containing aniline and nitrobenzene was treated through combining adsorption and bioaugmentation. Tests were conducted to investigate the inhibition of aniline and nitrobenzene on another biodegradation, the condition of adsorption separation, the biodegradation process through bioaugmentation and the variation of resin performance. The experimental results showed that aniline and nitrobenzene interactional inhibited another biodegradation. Adjusting pH to 4 and absorption velocity to 110 mL/h, the mixed wastewater of aniline (330 mg/L) and nitrobenzene (44 mg/L) passed through the adsorption column containing 10 mL resin NDA-150 (7.2 g). In the adsorption effluent the nitrobenzene concentration was not more than 4 mg/L and aniline concentration had no change. The residual aniline in effluent could be degraded through bioaugmentation. During this process about 597 mg nitrobenzene had been adsorbed by resin, in which 224 mg could be desorbed and biodegraded through bioaugmentation. The volumetric loading to nitrobenzene was 315 mg/(L·d). Through bioregeneration the adsorption capacity of resin NDA-150 could be recovered partly, which extent was limited by the bioavailability to nitrobenzene. After about 70 d recycled experiment the performance of resin NDA-150 was stable.
