摘要
卫生填埋是当今消除城镇固体废物常见方法之一。由此产生的垃圾渗滤液是一种高浓度有机物废水。即便少量此类渗滤液也会对地表水和地下水造成严重威胁。因此,垃圾渗滤液必须进行无害化处理,达标排放。在过去的几年中,厌氧膜生物反应器(AnMBR)技术由于相对与其他处理方式有着显著的优势而被认为是垃圾渗滤液处理优先考虑的方法并已经进行了广泛而深入的研究,特别是在各种类型的厌氧反应器与膜结合使用等方面。本文综述了厌氧膜生物反应器技术在城市垃圾渗滤液处理中的潜力。对实验室小试规模中各种因素对AnMBR生物和过滤性能的影响进行评述。
Nowadays, Sanitary landfill is one of the common ways to eliminate municipal solid waste. Landfill leachate is a high concentration organic wastewater. Even a small amount of such leachate poses a serious threat to surface water and groundwater. Therefore, landfill leachate must be treated innocuous and discharged. In the past few years, the anaerobic membrane bioreactor(AnMBR) technology had been considered as a priority method for landfill leachate treatment and widely and deeply studied because of its remarkable advantages over other treatments.,especially in various types of anaerobic reactors and membrane combination. In this paper, the potential of anaerobic membrane bioreactor for landfill leachate treatment was reviewed. The effects of various factors on the biological and filtration properties of AnMBR in the laboratory scale were reviewed.
