摘　　要：将维生素c（Vc）作为共代谢一级基质用于苯胺废水的好氧处理，考察了Vc与苯胺质量比、曝气时间、反应温度对苯胺废水处理效果的影响。在苯胺质量浓度为80mg/L、污泥沉降比（SV30）为10％～15％、Vc与苯胺质量比为1：6、曝气时间为16h、反应温度为30℃的条件下，苯胺去除率最高达99．98％；当苯胺质量浓度为800mg／L时，在常温下连续曝气26h，苯胺去除率为99．99％，达到GB8978—1996《污水综合排放标准》一级排放标准（1mg／L）。Vitamin C （Vc） was used as co-metabolism substrate in aerobic treatment of aniline wastewater. The affecting factors were studied, such as mass ratio of Vc to aniline, aeration time and reaction temperature. Under the conditions of aniline mass concentration 80 mg/L, SV30 10% -15%, mass ratio of Vc to aniline 1：6, aeration time 16 h and reaction temperature 30 ℃, the highest removal rate of aniline is 99.98% ; When the mass concentration of aniline is 800 mg/L and the aeration time is 26 h at atmospheric temperature, the removal rate of aniline is 99.99%. The concentration of aniline in the effluent can meet the first grade standard of national wastewater discharge standards （ 1 mg/L）.
