| 摘 要： | 在应用固定滤床处理污水过程中，由于过滤过程变化规律的复杂性，人们主要还是依靠实验得到的经验数据或经验准则关联式。本文直接分析均质滤料床过滤精确控制方程，合理利用方程的双曲特征，采用特征线计算法进行了数值模拟分析，消除了通常的向前差分格式引入的人工粘度造成的计算误差。结果表明特征线法数值计算稳定，空间、时间步长选取范围较大，模拟结果合理，变化趋势与实验及有关文献理论结论定性一致。

| Abstract: | In the process of sewage treatment by using fixed filtering bed, peeple relied much on the experiemental data or experiences as the complilated filtering process. The characteristics of the method was used to simulate the filtering process of the common fixed filter bed, finally indicated that by using the method of characteristics numerical calculation was stable, spatial, and stride selection scope oftime length was wide, analogue result was reasonable, the change tendency qualitative was consistent with ... |
