摘　　要：渗滤液成分复杂,采用单一的处理方法不能满足其处理要求,需要通过不同方法进行优化组合与灵活应用。年轻填埋垃圾渗滤液具有良好的生化处理可行性,一般采用生物(包括好氧、厌氧或好氧与厌氧相结合)法,或以生物法为主结合前处理和物化深度处理的手段进行处理;而老龄填埋场渗滤液B/C逐渐降低可生化性差、氨氮浓度逐渐升高、难降解污染物质成分复杂且浓度高。针对老龄填埋场的渗滤液的水质特性,选择适宜的物化与生物相结合的手段对其处理,即提高B/C和降低氨氮浓度,又达到去除难降解有机物的目的。The composition of leachate is complex, adopted one kind of treatment method can not qualify its disposal requirement. Various measure methods must be applied in a optimal and agility way. Leachate of young landfill possess good biological degradation ability, and can be deal with biological treatment or combine with deepness treatment; While to leachate of aged landfill, its B/C reduced gradually, possess poor biological degradation ability, high NH3-N and refractory organic. It is important to aim at improving B/C of leachte, decreasing NH3-N and refractory organic by selecting appropriate physical-chemical treatment combine with biological treatment.
