| 摘 要： | 采用序批式反应器,研究了好氧颗粒污泥处理畜禽养殖沼液中传统和新兴污染物的去除特性,以及系统的微生物群落结构演变情况.结果表明,畜禽沼液所含高浓度污染物不会对好氧颗粒污泥结构产生显著毒性胁迫,好氧颗粒污泥系统可实现对沼液所含有机物和氨氮的稳定去除.系统出水平均化学需氧量和氨氮浓度分别为(267±81) mg·L~(-1)和(62±12) mg·L~(-1),去除效率分别为73%±8%和91%±2%.同时,也可实现对沼液所含四环素类和磺胺类抗生素的有效去除,去除效率分别为65%±16%和98%±2%.但对磷素的去除效率较低,约为16%±2%.好氧颗粒污泥系统处理沼液过程中微生物群落结构稳定,但其中功能微生物菌群丰度会受到水质的作用影响,从毛单胞菌科Comamonadaceae(相对丰度约为16. 66%)为污泥中的主导微生物群落.

| Abstract: | This research investigated the performance of an aerobic granular reactor treating biogas slurry from pig farm. Results indicated that the granular structure of aerobic sludge was not affected by the high pollution concentrationsin the biogas slurry. Although a low removal rate of phosphate was found in this study (about 16%±2%), organic matter and ammonia nitrogen showed stable removal and transformation in the granular system, and the effluent concentrations of those components were (267±81)mg·L-1 and(62±12)mg·L-1, respectively. In addition, the removal rate of sulfamethazine and tetracycline was 98%±2% and 65%±16%, respectively. During the process biogas slurry treatment, bacterial communities in the aerobic granular reactor remained stable, and Comamonadaceae was the dominant bacteria (relative abundance ofapproximately 16.66%). |
