深圳下坪填埋场渗滤液产生量预测研究

Prediction for Leachate Generation at Shenzhen Xiaping MSW Landfill.

对垃圾填埋渗滤液产生量预测模型进行了比较,选择经验—合理式模型作为填埋场渗滤液产生量的预测模型。综合下坪垃圾填埋场不同汇水面积、降雨量和渗滤液量的现场实测数据,采用线性回归确定了模型参数,通过模型预测渗滤液产生量与现场实测渗滤液产生量的对比分析了本模型的精度和可靠性,从而为填埋场渗滤液产生量的预测及收集处理系统的设计、管理提供科学依据。

Different prediction models for leachate generation from MSW landfills were compared in this paper,and the empiricism-rational model was recommended as the prediction model for leachate generation at Shenzhen Xiaping landfill.Combining the flow area,rainfall and leachate generation detected on site from at the landfill,the parameters in this model was determined by lineal regression analysis.The accuracy of this model was assessed by comparing with the leachate generation monitored on site,and the result indicated that the empiricism-rationl model was a compacted and practical model.It thus provides a scientific basis for environmental impact predivtion and assessment of leachate generation and for designing and management of leachate collection and treatment systems.
