摘要
      使用生化甲烷电位测试，在两种氧化石墨烯浓度（每克挥发性固体0.025和0.075克氧化石墨烯）下，研究了氧化石墨烯对废活性污泥厌氧消化的影响。在厌氧处理之前和之后，在固相和液相中监测36种药物的出现。氧化石墨烯的加入提高了检测到的大多数药物的去除率，即使是那些被认为对生物降解具有持久性的药物，如阿奇霉素、卡马西平和双氯芬酸。在没有氧化石墨烯和氧化石墨烯浓度最低的情况下，没有观察到甲烷的最终比产量有显著差异，但氧化石墨烯的最高浓度部分抑制了甲烷的产生。添加氧化石墨烯不影响抗生素抗性基因的相对丰度。最后，通过添加氧化石墨烯，检测到包括细菌和古菌在内的微生物群落的显著变化。
Abstract
The effect of graphene oxide on the anaerobic digestion of waste activated sludge was investigated at two graphene oxide concentrations (0.025 and 0.075 g graphene oxide per g volatile solids) using biochemical methane potential tests. The occurrence of 36 pharmaceuticals was monitored in the solid and liquid phases before and after the anaerobic treatment. The addition of graphene oxide improved the removal of most pharmaceuticals detected, even those that are considered persistent to biological degradation, such as azithromycin, carbamazepine, and diclofenac. No significant differences were observed in the final specific methane production without graphene oxide and with the lowest graphene oxide concentration, yet the highest graphene oxide concentration partially inhibited methane production. The relative abundance of antibiotic resistance genes was not affected by the graphene oxide addition. Finally, significant changes in the microbial community including bacteria and archaea were detected with graphene oxide addition.
