摘　　要：为探究藻菌膜生物反应器处理抗生素废水的效能及膜污染状况,构建了藻菌膜生物反应器(R_(1))和传统膜生物反应器(R_(2))用于处理磺胺甲恶唑(SMX)抗生素废水。结果表明,相比于R_(2)反应器,R_(1)反应器对COD、NH_(4)^(+)-N、PO_(4)^(3-)-P和SMX的平均去除率分别提高了0.48%、10.45%、42.16%、38.81%,藻菌膜生物反应器的处理效能明显优于传统膜生物反应器。通过对跨膜压差(TMP)、胞外聚合物(EPS)等的分析发现,R_(1)反应器的清洗周期更短,EPS含量比R2反应器增加52.77%,说明藻菌膜生物反应器的膜通透性降低,膜污染状况加重。In order to explore the efficiency of algal-bacterial membrane bioreactor treating antibiotic wastewater and the membrane pollution status,algal-bacterial membrane bioreactor(R_(1))and traditional membrane bioreactor(R_(2))were constructed and used to treat sulfamethoxazole(SMX)antibiotic wastewater.The results showed that,the average removal rates of COD,NH_(4)^(+)-N、PO_(4)^(3-)-P and SMX were 0.48%,10.45%,42.16%and 38.81%higher respectively in R_(1)than that in R_(2),which indicated that the treatment efficiency of R_(1)reactor was superior to R_(2)reactor.According to the analysis on transmembrane pressure difference(TMP)and extracellular polymer(EPS),it could be found that,compared to R_(2)reactor,R_(1)reactor revealed shorter cleaning cycle,and the EPS content was 52.77%higher,which indicated that the membrane permeability of algal-bacterial membrane bioreactor decreased and its membrane fouling was aggravated.
