The problem of salinity accumulation of reverse osmosis(RO) concentrate to domestic waste landfill was discussed.The prediction model for the change of leachate conductivity was established,and the simple calculation formula of leachate conductivity with time was deduced.Combined with the prediction results,the optimization scheme of the depth treatment process of the leachate treatment station was put forward,which can provide the basis for the prediction of the leachate water quality and process selection in the design process.%对反渗透(RO)浓缩液回灌生活垃圾填埋堆体的盐分累积问题进行了探讨,建立了渗沥液电导率变化的预测模型,推导出渗沥液电导率随时间变化的简便计算公式,并结合预测结果提出渗沥液处理站深度处理工艺的优化方案,为设计过程中的渗沥液水质预测和工艺选型提供依据.
