air scour造句

• As backwash is the key of renewing and keeping up the function of filter , so some factor optimization experiments of backwash have been done . the optimum operating parameters of air scour and water backwash of ceramics media are chosen by multiple factors experiments : qa = 15 l / s ? m2 , qw = 5 l / s ? m2 , t1 = 1min , t2 = 5min , t3 = 5min
  经多组实验正交分析结果后得出了涂铁陶粒滤池反冲洗实验的最佳参数组合：气冲强度15l / s ? m2 ，水洗强度5l / s ? m2 ，单气预冲1min ，气水同时反冲洗5min ，单水漂洗5min 。
