摘　　要：为有针对性地原位强化污水处理中有机微污染物的微生物降解,以布洛芬为目标有机微污染物(OMPs),探究了序批式生物反应器对布洛芬强化生物降解效果及其机理。结果表明:提高污泥质量浓度和改性沸石投加能够显著增强反应器中NH4+-N和布洛芬的去除效果,去除率较对照组分别提高了129.3%和214.5%。该强化处理体系中脱氢酶含量、潜在硝化速率、比亚硝酸盐氧化速率、羟胺氧化率分别提高了2.66、1.39、1.67、1.10倍;而且富集了代尔夫特菌、硝化螺旋菌、特吕珀菌等相关功能细菌,进而提高了布洛芬的生物强化降解性能。The removal efficiency of organic micropollutants in conventional sewage treatment process is low,which has led to a potential threat to the ecosystem and human health.In this study,ibuprofen was selected as the target OMPs to investigate the enhanced biodegradation of ibuprofen and its mechanism in a sequential batch bioreactor.The results showed that the removal efficiency of NH4+-N and IBP was significantly enhanced by increasing sludge mass concentration and adding modified zeolite,the removal rates were increased by 129.3%and 214.5%respectively,compared with the control group.Dehydrogenase content,potential nitrification,specific nitrite oxidation rate and hydroxylamine oxidation rate were increased by 2.66,1.39,1.67 and 1.10 times in the enhanced treatment system,respectively.Moreover,functional microlcial community was enriched such as Delftia,Nitrospira and Thauera,thereby IBP degradation was strengthened.
