本文通过模型试验比较了三组滤料的过滤性能，证明了气水反冲洗较单水反冲洗具有树大的优越性，得出了适合三级滤料的气水反冲洗最佳参数组合范围，为粗均粒滤料和气水反冲洗的结合使用指明了广阔的应用前景．

The filtering property of three common filtering media on the condition of air-water backwashing are compared based on the testing of the models. The results prove air-water backwashing has advantage over water backwashing. The optimal values suited to the three filtering media are obtained. Also the prospects for the wide use of coarse filter-ing media in conjunction wit...
