在分析均质滤料床过滤方程的基础上，合理选择含深度步长的参数α，从而将精确的过滤连续性方程简化． 采用有限差分法对简化方程进行离散，并用迭代法求解，得到了均质滤料床滤后出水浓度模拟结果． 经实验验证，两者吻合较好，从而为研究均质滤料床过滤运行情况提供了有效手段．
On the basis of analyzing the filter equation of homogeneous filter bed, the parameter α with depth step length is selected reasonably, which simplifies the exact filter continuity equation. The finite difference method was used to discretize the simplified equations, and iterative method was used to obtain the simulation results of the effluent concentration after filtration in the homogeneous filter bed. The experimental verification shows that the two are in good agreement, which provides an effective means for the study of the filtration operation of the homogeneous filter bed.
