摘要
采用分置式膜生物反应器(MBR)进行去除模拟废水中a-烯基磺酸钠(AOS)的实验。结果表明:MBR对阴离子表面活性剂的去除率高于99%．考察了AOS生物降解的影响因素,确定其适宜降解条件为:气体流量0．3 m3／h,活性污泥质量浓度6 648 mg／L,外加碳源COD质量浓度400 mg/L．
Using split type membrane bioreactor （MBR）can achieve effective removal of alpha olefin sulfonate （AOS）in simulant wastewater. The result demonstrated that the removal efficiency was higher than 90%. Several factors influencing alpha olefin sulfonate biodegradation were investigated. The optimal conditions were confirmed： flux of gas = 0.3 m^3/h,the activated sludge concentration = 6648 mg/L, the additive COD =400 mg/L.
