  1. 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

    經多組實驗正交分析結果后得出了塗鐵陶粒濾池反沖洗實驗的最佳參數組合：氣沖強度15l / s ? m2 ，水洗強度5l / s ? m2 ，單氣預沖1min ，氣水同時反沖洗5min ，單水漂洗5min 。
  2. The ratio of the length to the depth of scour hole decreases with the increasing scour depth, in spite of the reason is the increase of the air concentration, the decrease of the jet velocity or the decrease of the jet thickness. 5. governing equations of the aerated jet flow are established

    摻氣對沖坑形態並沒有實質性的影響，沖坑的寬深比隨沖坑深度的減小而增大，無論造成沖坑深度減小的原因四） 1大學i學博士學位論文是摻氣、降低流速還是減小入射水舌厚度，其變化規律都可用相同的直線關系表示。
  3. The relationship between the air concentration and the scour depth can be expressed as an exponential function. aeration does not affect the shape of scour hole

    摻氣濃度c _對沖坑深度的影響，可表達為摻氣濃度與沖坑無量綱深度的冪函數關系。
