固体废弃物渗滤液组分动态变化预测

Prediction of Leachate Component Variation in Municipal Solid Waste Landfill

渗滤液(Leachate)是城市固体废物填埋场(MSWLF)污染环境的主要来源之一,因此掌握其水质变化规律是研究填埋场对环境污染的首要问题。渗滤液的主要来源是大气降水,使用垃圾淋滤的方法模拟大气降水,利用实验结果建立模拟模型,揭示了渗滤液组分随降水的变化规律。可以预测垃圾填埋后渗滤液污染组分的浓度变化。为研究填埋场渗滤液组分变化及确定其处理对策提供了理论依据。

Leachate is one of the major pollution sources in municipal solid waste (MSW) landfills, so, to the environmental pollution, what matters most seems to master changing laws of water quality of the leachate. Leachate is mainly from precipitation. The study grasps the changing rules of several leachate components that alter in terms of precipitation with leaching the waste, and establishes predictive model on the basis of lab data, successively anticipating concentration variance of pollutants that are going to be eluviated into leachate after landfilling. Convincing data for studying and treating the landfill leachate are provided.
