title: [Prediction of landfill leachate production in cold area conversion].
abstract: 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 leachate production variability and the impact of leachate recirculation on sanitary landfill, two simulated landfill reactors were constructed outdoors, which were filled with the same municipal solid waste. One reactor was provided with leachate recirculation and the other without as a control. On the basis of the obtained leachate production data and evaluation of the available leachate 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 leachate production, design of leachate collection and treatment system. Besides, this study indicated that leachate recirculation was feasible for leachate treatment in the cold areas.
