摘　　要：东北地区4季变化明显,冬季寒冷,冰冻期较长,渗滤液的产生具有明显的不连续性.为了考查该气候条件下渗滤液产生量的变化情况以及回灌对渗滤液产生量的影响,在室外建立2个处理同类生活垃圾的模拟垃圾填埋场,其中1个渗滤液不回灌做为对照,另1个带有渗滤液回流装置,进行全年渗滤液产生量的跟踪监测.在对垃圾渗滤液产生量预测模型进行综合比较的基础上,基于全年降雨量和渗滤液产生量的实测数据,采用线性回归确定了经验公式法的模型参数,通过模型预测值与现场实测值的对比,分析了预测模型的可靠性与准确性,从而为寒冷地区垃圾填埋场渗滤液产生量的预测、收集和处理系统的设计以及渗滤液回灌技术的推广应用提供科学依据.Leachate production is evidently discontinuous in the chilly northeast areas because of the distinct 4-seasons conversion and long frozen time. In order to investigate into the leaehate production variability and the impact of leaehate recireulation on sanitary landfill, two simulated landfill reactors were constructed outdoors, which were filled with the same municipal solid waste. One reactor was provided with leaehate reeireulation and the other without as a control. On the basis of the obtained leaehate production data and evaluation of the available leaehate predictive models, the empirical model was recommended and the parameters within the formula were determined through linear regression analysis, which was proved to be reliable and practical. The results provided a scientific basis for the prediction of leaehate production, design of leaehate collection and treatment system. Besides, this study indicated that leachate reeireulation was feasible for leaehate treatment in the cold areas.
