中文摘要：

将污泥基活性炭（SBAC）与膜生物反应器（MBR）联用对垃圾渗滤液进行处理，既可以降低活性炭的使用成本，同时又实现了污泥基活性炭的应用。采用SBAC／MBR工艺处理垃圾渗滤液，并与MBR工艺进行对比，研究了两反应器内污泥混合液中EPS、SMP以及膜表面EPS的含量和组成，分析了其对TMP的影响。在整个运行过程中，SBAC／MBR内污泥混合液中的EPS、SMP以及其中的蛋白质和多糖含量均随运行时间先升高后降低，在一个操作周期内，膜表面EPS及其蛋白质、多糖含量均随运行时间逐渐上升，TMP随运行时间呈先缓慢上升后快速上升的变化规律。SBAC可以有效降低污泥混合液中EPS和SMP的含量和组成比例，改善膜表面泥饼层的性质和结构，减缓膜表面泥饼层的形成和增长以及膜孔内的堵塞现象，从而减轻了膜污染。在一个操作周期内，投加SBAC主要是延长了TMP的缓慢上升阶段，从而使膜组件的清洗周期由17d延长至21d。

英文摘要：

Landfill leachate was treated by sludge-based activated carbon （SBAC） and membrane bioreactor （ MBR）, which could reduce the cost of activated carbon and at the same time realize the ap- plication of SBAC. SBAC/MBR and MBR were compared for treating landfill leachate, and the contents and components of EPS and SMP in sludge mixed liquor, the contents and components of EPS on the sur- face of membrane, and their influence on TMP were investigated. The results showed that EPS, SMP, proteins and polysaccharides in the sludge mixed liquor of SBAC/MBR first increased and then decreased with operation time. EPS, proteins and polysaccharides on the surface of membrane in SBAC/MBR in- creased gradually with time, and TMP in SBAC/MBR increased with time first gradually and then rapidly in an operation cycle. SBAC could reduce contents and components of EPS and SMP, improve properties and structure of the cake layer on the surface of membrane, slow down the formation and growth of cake layer, reduce clogging in the membrane pores and decrease the membrane fouling. In an operation cycle,the slow increase period of TMP in the reactor was prolonged by adding SBAC, which extended the clean- ing cycle of membrane module from 17 d to 21 d.
