垃圾渗滤液废水站设计摘 要渗滤液是一种作为渗流通过废物的雨水和水分而形成于堆填区高强度污染废水。在垃圾渗滤液，有机物质的形成是从废物转移到液体容纳体中，造成危害的接收水体。垃圾渗滤液具有 NH3-N 高、COD 浓度高等特点，传统的处理工艺往往存在较大的压力，出水水质难以得到保证。MBR 工艺很好地解决了这方面的问题，在先进的生物处理工艺中，膜生物反应器（MBR）是最重要的过程，模块和膜一般含有高混合液悬浮固体活性污泥（污泥）生物反应器组成一个比 10，000mg / L 更大的系统时，膜生物反应器作为物化后处理中的应用可以达到预期的高水质标准。MBR 工艺对污染物去除率高，对污水变化适应性也很强，系统启动速度快，另外，该工艺节约占地，操作、维护简单。逐步成为国内外垃圾渗滤液处理的主流工艺之一。关键词：膜生物反应器；垃圾渗滤液；纳滤AbstractLeachate is a high strength waste water formed as a result of percolation of rain-water and moisture through waste in landfills．During the formation of leachate， organic and in organic compounds are transferred from waste to the liquid medium and pose a hazard to the receiving water bodies．Treatment technique of garbage seeping filtrates is characterized in high NH3-N and COD concentration.Traditional treatment technique tends to have some treatment pressure and can not guarantee the effluent water quality.MBR technique solves this problem ideally and has the advantages of high rate of removal of pollutants， Among advanced biological treatment processes，membrane bio-reactor (MBR) is the most important process ，which consists of a membrane module and a bioreactor containing generally activated sludge with high mixed liquor suspended solids (MLSS) of greater than10 ，000mg/l．The application of membrane bioreactor as a main treatment after physicochemical application seems to be promising due to the expected high effluent quality．MBR technique high adaptability to sewage change and quick syste...
