摘　　要：通过蒸发实验确定两种垃圾渗滤液的氨氮含量和浓缩液粘度等,提出了双效机械蒸汽再压缩蒸发+冷凝液厌氧/好氧处理的联合处理工艺。建立数学模型,研究了蒸发温度、蒸发温差和浓缩倍数与系统总的蒸发面积和压缩机功率的关系。The ammonia nitrogen and viscosity of two kinds of landfill leaehate were determined by evaporationexperiments. A combined process of double-effect mechanical vapor re - compression＋anaerobic/aerobic process wasproposed. By establishing mathematical model, the relationship between evaporation temperature, evaporation temperaturedifference and concentration muhiple and total evaporation area and compressor power were studied.
