摘　　要：以Amirtharajah的关于气水反冲洗的理论为基础,通过对其理论及经验公式的分析和研究,并结合当前运行良好的水厂滤池的生产数据,进一步确定和验证了气水反冲洗的相关控制指标,并得出了气水反冲洗过程中水的强度与气的强度关系的新的经验公式。结果表明,为获得滤池反冲洗的较佳状态,应根据L/D在0.30～0.50内对V/Vmf酌情取值。Based on air-water backwash theory of Amirtharajah,the relative control parameters of air-water backwash were determined and verified through analysis by theoretical and experiential formula.Combined the filter operation data under good conditions,the new experiential formulas of air and water strength related in filter air-water backwash process were established.The result showed that value selection of V/Vmf should be 0.30～0.50 according to L/D,in order to get better filter backwash condition.
