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(R1)和传统膜生物反应器(R2)用于处理磺胺甲恶唑(SMX)抗生素废水.结果表明,相比于R2反应器,R1反应器对COD、NH4+-N、PO43--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,R1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.
Study on efficiency of algal-bacterial membrane bioreactor treating antibiotic wastewater and membrane fouling thereof
In order to explore the efficiency of algal-bacterial membrane bioreactor treating antibiotic wastewater and the membrane pollution status,algal-bacterial membrane bioreactor(R1)and traditional mem-brane bioreactor(R2)were constructed and used to treat sulfamethoxazole(SMX)antibiotic wastewater.The re-sults showed that,the average removal rates of COD,NH4+-N、PO43--P and SMX were 0.48%,10.45%,42.16%and 38.81%higher respectively in R1than that in R2,which indicated that the treatment efficiency of R1 reactor was superior to R2 reactor.According to the analysis on transmembrane pressure difference(TMP)and extracel-lular polymer(EPS),it could be found that,compared to R2 reactor,R1 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.
