| 摘 要： | 以多孔陶瓷作为载体,并分别以葡萄糖和苯甲酸作为碳源培养生物膜,在好氧条件下比较不同生物膜去除COD和氨氮的速率.借助于微电极技术对两种生物膜微观结构的研究表明：以葡萄糖为碳源所培养的生物膜对氧的利用率高于苯甲酸.动力学分析结果表明：葡萄糖培养的生物膜其最大氧消耗速率为80 mg O2/（gVSS.h）,远大于苯甲酸培养的生物膜20 mg O2/（gVSS.h）]的氧消耗速率.分子生物学分析结果表明,以葡萄糖为碳源培养的生物膜内的微生物种类数是苯甲酸培养的生物膜内的1.5倍.

| Abstract: | Glucose and benzoic acid,as carbon source,were respectively used to culture biofilm based on porous ceramic carrier,and the two carbon sources were compared in COD and ammonia nitrogen removal under aerobic condition.By means of microelectrode,the microstructures of the biofilms were analyzed according to kinetics to get that maximum oxygen consumption rate was 80 mg O2/(gVSS·h) in the biofilm cultured by glucose,which was much more than that by benzoic acid with 20 mg O2/(gVSS·h).The number of microbial species in the biofilm cultured by glucose was as 1.5 times as that by benzoic acid according to molecular biological analysis. |
