摘　　要：针对矿化垃圾筛分后<15mm组分性质进行研究,并以该组分为填料设计制造矿化垃圾生物反应床处理渗滤液,研究表明,矿化垃圾具有较大的吸附比表面积,较强的离子交换容量,较高的有机质含量,含有种类和数量可观的微生物种群可供生物降解作用,是很好的污水处理生物介质。工程应用表明:渗滤液经过三级矿化垃圾生物反应床串联处理后,CODCr和NH4+-N的总去除率达到90%和95%以上,可稳定达到国家二、三级渗滤液排放标准。This paper is going to study the constituents of aged-refuse less than 15 mm after being sieved and design aged-refuse bioreactors to treat landfill leachate with fillers of those constituents.It is shown that aged-refuse has larger adsorption specific surface area,biggish ion exchange capacity,higher contents of organic matter and considerable microorganism species groups both on variety and quantity which are used for biodegradation.Thus it is a kind of excellent biomedium in waste water treating.It is indicated in engineering applications that the total removal rate of COD_ Cr and NH^+_4-N can be seperately high than 90% and 95% and the effluent can come up to the state landfill leachate discharging standard within the second grade or the third grade stably after being treated by three aged-refuse bioreactors in-line.
