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(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.
Abstract
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.
