摘要

提出了水悬浮物在快速过滤条件下的非线性深床澄清的基本数学问题。有选择地介绍了用精确法求解粘附函数线性形式和用近似法求解非线性形式的结果。通过对主要过滤特性进行并行精确和近似计算,说明了得出的依赖关系。对由于原始模型简化而导致的计算误差进行了估算,结果表明近似解法具有很高的准确性。

Modeling of nonlinear clarification of aqueous suspensions at rapid filters
The basic mathematical problem of nonlinear deep bed  clarification of aqueous suspensions at rapid filters is formulated. The results of its solution using exact method for the linear form of the adhesion function and approximate method for the nonlinear form are selectively presented. The derived dependencies are illustrated by parallel exact and approximate calculations of the main filtration characteristics. An estimation of the сalculated errors due to simplification of the original model was carried out indicating the high accuracy of the approximate solution.
