摘要
Abstract
Based on percolation theory and network model, an equation describing the relationship between filtration coefficient and pore size distribution (PSD) of filter media was established. Using this equation, PSD parameters of the filter medium could be obtained from experimental data. Moreover, the result was also compared with PSD parameters estimated by other methods and other data in the literature. In order to validate this method, the obtained PSD parameters were used in the simulation of straining-dominant filtration, and the simulation result was consistent with experimental data. The filtration model based on percolation theory for PSD parameter estimation was relatively accurate and effective.关键词
