泰兴市非饱和带与饱和带间固液界面传质模型的推导
Derivation of solid-liquid interfacial mass transfer model between unsaturated zone and saturated zone in Taixing
摘要
Abstract
Unsaturated zone and saturated zone are closely related,and the establishment of solid-liquid interface mass transfer model at the junction of them can provide a theoretical basis for unsaturated zone coupling saturated zone model,and is also meaningful for better predicting groundwater pollution trend.Taking Taixing,Jiangsu Province as the research object,four kinds of solid-liquid interfacial reactions,namely adsorption and desorption,particle film diffusion,distribution and dilution were combined with the characteristics of unsaturated zone and saturated zone.A solid-liquid interfacial mass transfer model was derived which linked the unsaturated zone and saturated zone together.Matlab was used to simulate the change of pollutant concentration in groundwater when model parameters change.The results showed that the model was feasible,while the polluted sites and pollutant types may affect the simulation results.关键词
