摘要
将好氧MBR处理垃圾渗滤液装置中的污泥混合液进行合理分离,通过死端过滤实验和膜污染阻力测定实验,以确定MBR中造成膜污染的优势污染物和优势污染阻力。实验结果表明,上清液中的胶体物质和大分子粘性有机物是造成膜污染的优势污染物;膜污染阻力主要由凝胶极化阻力和外部污染阻力构成,二者之和占总污染阻力的95%以上。
The aim of the study on a landfill leachate treatment was to determine the dominated pollutants and fouling resistance of the membrane in membrane bioreactor（MBR）by the separation of sludge separation,dead and filter test and membrane fouling resistance measurement test.The results indicated that the colloidal materials and macromolecules viscous organisms in supernatant liquid of the sludge mixed liquor were the dominated pollutants which caused membrane fouling;and the membrane fouling resistance was composed mainly of gelatification and polarization resistance and external fouling resistance,which were more than 95% of the total fouling resistance.
