摘要
探讨了现阶段用于滤池反冲洗的几种冲洗方式，分析了单一水反冲洗不佳的原因，及先气后水工艺与气水同时冲洗工艺、悬移式气冲工艺与固定式气冲工艺的特点，进而说明悬移式气水同时冲洗工艺具有造价低、配气均匀、维修方便。
Abstract Several current filter backwash operations are discussed. The reasons that cause poor effect of backwash by water alone are explained and the specialties of backwash operations with water followed by air, simultaneous water and air suspended travel type and fixed type of air are described. Finally the authors indicate that the suspended travel type of simultaneous air water backwash has advantages of low investment, well distributed airflow, easy to maintenance and free of blockage.
