摘要
采用模拟生活污水,在相同的运行条件下,对比研究了膜-生物反应器(MBR)与序批式活性污泥法(SBR)对10种典型药品和个人护理品(PPCPs)的去除效果.研究结果表明,两种反应器对不同目标物PPCPs的去除效果存在一定的差异:MBR和SBR对甲氧苄氨嘧啶(TRM)和红霉素(ERY)的去除无明显差别;苏必利(SLP)和卡马西平(CBZ)在两反应器中均不能得到有效去除;但对于其他目标物,尤其是咖啡因(CAF)、酮洛芬(KTP)、避蚊胺(DEET),MBR的去除率明显高于SBR.总体上,MBR在出水的安全性和稳定性上存在着一定的优势.
Comparisons between membrane bioreactor （MBR） and sequencing batch reactor （SBR） on the removal of ten typical pharmaceuticals and personal care products （PPCPs） were caried out. The two bioreactors were operated stably using simulated domestic wastewater under the same condition. The results showed that the removal efficiencies varied with the target compounds. There was no significant difference between the two bioreactors on the removal of trimethoprim （TRM） and erythromycin （ERY）. Sulpiride （SLP） and carbamazepine （CBZ） were barely effectively removed. The most abundant compounds among the selected PPCPs were effectively removed in MBR, especially the removal of caffeine （CAF）, ketoprofen （KTP） and N,N-diethyl-m-toluamide （DEET） was more effective in MBR than SBR. On the whole, MBR has certain advantages on the safety and stability of the effluent over SBR.
