【摘要】 反冲洗是保证曝气生物滤池正常运行的重要环节。通过试验,确定曝气生物滤池的反冲洗方式采用气、水联合反冲洗效果较好,水冲洗强度为5～7L/(m2·s),气冲强度为13～17L/(m2·s),反冲洗周期为24h,反冲洗时间10～15min。滤池冲洗后需要5～6h能恢复到最佳处理状态。更多还原

【Abstract】 Backwash is very important for ensuring the successful performance of biological aerated filter (BAF).Through the experiment, combined air-water backwash mode was taken in BAF backwash and water backwash were 5～7 L /(m2·s) and air backwash 13～17 L /(m2·s) with the backwash period 24 h and the backwash time 15 min. It took 5～6 h to recover to the optimal performance after backwash.更多还原
