摘　　要：采用旋转粘度计测试了CODCr浓度为 10 0 0～ 75 0 0 0mg L、温度在 5～ 70℃范围内的渗滤液粘度。实验结果表明 ,相同温度下渗滤液的粘度值与CODCr浓度呈线性关系 ;不同浓度渗滤液中溶质性质的差异是造成渗滤液比浓粘度差异的原因 ;研究填埋场水分运移时 ,可以不考虑粘度对渗滤液流动的影响。The viscosity of leachate with different COD Cr concentrations (from 1 000 to 75 000 mg/L ) from laboratory experiments was tested in different temperature (from 5 to 70 centigrade).The experimental results showed that the viscosity of leachate at similar temperatures is linear with COD Cr concentration.The different specific viscosities of leachate with different concentrations were ascribed to the solute in leachate.It is acceptable to omit the influence of viscosity when studying the moisture movement in the landfills.
