论文摘要
在有资金来补贴过滤器的初始成本，用于使用和维护的可用培训，本地可用的沙子以及能够移动过滤器的运输网络的情况下，慢砂过滤是最合适的。由于缓慢过滤的实验研究需要很长时间，因此理论分析，建模和仿真研究变得很重要。缓慢过滤的理论模型尚未充分发展。有几个原因是阻碍建模和模拟：由于水与污染与过滤器的相互作用的复杂性以及基本过程中动力学系数的详细值缺乏详细值。使用COMSOL建模的多物理模型，其中一组复杂的Navier-Stokes方程是在数值上求解的，并且使用分子意识，对动力学系数的分子意识用于研究各种几何形状和缓慢过滤的构造类型。
Slow sand filtration is most appropriate where there is funding to subsidize the initial cost of the filter, available training for use and maintenance, locally available sand, and a transportation network capable of moving the filter. Since the experimental study of slow filtration is taking a long time, theoretical analysis, modelling and simulation studies become important. Theoretical models of slow filtration are not yet sufficiently developed. Several reasons are hindering modelling and simulation: due to the complexity of the interaction of water and pollution with filters and the lack of detailed values for the kinetic coefficients in elementary processes. Multiphysics modelling using Comsol, where a complex set of Navier-Stokes equations is numerically solved together, with the molecular awareness for the kinetic coefficients, was used to studying various geometries and construction types of slow filtration.
