摘　　要：随着水环境中抗生素污染的日益严重,开发高效、稳定的抗生素去除技术至关重要。以Bi_(2)MoO_(6)/FeVO_(4)核壳纳米材料为催化剂,超滤膜为分离手段,将超滤膜与声光催化技术相耦合而构建了声光催化膜反应器(SPMR),并探究其对水中环丙沙星(CIP)的去除效果。结果表明,SPMR对CIP的降解率随水力停留时间(HRT)增加而提高,当HRT为60 min时,降解率可达94.56%。中空纤维膜能有效截留催化剂,保证反应器中催化剂浓度稳定。在SPMR降解CIP过程中,羟基自由基(·OH)和空穴(h^(+))起主导作用。SPMR对实际水体和模拟水中的CIP均有良好的去除效果,降解率均在80%以上,证实了声光催化技术可用于去除不同水体中的CIP。As antibiotic contamination in aquatic environments intensifies,it becomes crucial to develop efficient and stable technologies for antibiotic removal.The sono-photocatalytic membrane reactor(SPMR)was investigated to use Bi_(2)MoO_(6)/FeVO_(4)core-shell nanomaterials as catalysts and ultrafiltration membranes for separation,focusing on its effectiveness in removing ciprofloxacin(CIP)from water.The degradation rate of CIP in the SPMR increased with hydraulic retention time(HRT)and reached 94.56% when HRT was 60 min.The hollow fiber membrane effectively retained the catalyst,ensuring stable catalyst concentration within the reactor.Hydroxyl radicals(·OH)and holes(h^(+))played a key role in the degradation process.The SPMR exhibited excellent removal efficiency for CIP across various real and synthetic water sources,with degradation rates consistently above 80%.This research confirms the feasibility of sono-photocatalytic technology for CIP removal in different water bodies.
