The production and processing of pyrotechnics produce aniline wastewater， which causes a great pollution to the environment. To provide an efficient strain resource for aniline degradation， a strain Q6 with aniline as the only carbon source and energy growth was isolated from the activated sludge in the aerobic aeration tank of the chemical wastewater treatment plant. Through morphological observation， physiological and biochemical characteristics and 16S rDNA gene sequence phylogeny analysis， the strain was identified as Acidovorax sp. The effects of inoculum amount， temperature， pH value and additional carbon and nitrogen sources on aniline degradation by strain Q6 were studied. Meanwhile， the degradation kinetics of aniline at different initial concentrations and the growth kinetics of strain Q6 were fitted. The results showed that under the conditions of temperature 23-37 ℃ and pH 5-8， strain Q6 could degrade aniline efficiently， and ammonium chloride was the best co-metabolizing nitrogen source to promote the degradation of aniline.The optimum conditions of 33 ℃， pH 7 and inoculation amount of 10%， the degradation rate of aniline at different initial concentrations （200-3000 mg·L^-1） was above 95.0%， and the degradation process of aniline showed first-order and zero-order kinetics. The growth process of Q6 conformed to the Haldane equation with a maximum specific growth rate μ_max of 0.130 h^-1， a half-satiation constant K_s of 190 mg·L^-1 and the inhibition constant K_i of 8497 mg·L^-1. The results show that strain Q6 has unique potential in the treating industrial wastewater containing high concentration of aniline.
