backwash water 中文意思是什麼
backwash water
解釋
反沖水-
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 。 -
The results showed : fiber ball has the highest efficiency among the three, its water - consumption is small in backwash and it is more wear - resisting ; the comprehensive property of quartz grain filter material is poorer ; manganese grain has an effective removal of fe ( superscript 2 + ) and mn ( superscript 2 + ) but water - consnmption is big
結果表明纖維球濾料除鐵濾速高，反沖洗耗水量小且耐磨損；石英砂濾料綜合性能次之；錳砂雖然除鐵效果較好，但反沖洗耗水量大。 -
Pilot - scale experimental results showed that, comparing to conventional gravity filtration, the up - flow filtration has greater capacity in containing removed suspended solid and producing filtrate under the test conditions. coarse media with particle diameter ranging 0. 63 - 2. 00mm were used in order to apply relatively higher backwash rate of 21 l / ( m2. s ) for achieving better media clean - up after a filtration run. under the test conditions, the media thickness ranging 82 - 85 iron, water temperature ranging 6 - 27, and influx turbidity of 30 ntu, it achieved the results of the average filtration rate ranging 16 - 18 m / h, the average effluent turbidity of 1 ntu, and action cycle ranging 14 - 24h
中試研究結果表明，粗石英砂濾料上向流過濾比傳統的重力流過濾具有更大的含污能力和產水量，為適用較高的反沖洗強度（ 21l （ m ~ 2 ? s ） ）以便濾料清洗更干凈，採用粒徑范圍為0 . 63 2 . 00mm的粗石英砂濾料，濾層厚82 85cm ，水溫6 27 ，進水濁度為30ntu左右等情況下，能獲得平均濾速為16 18m h 、平均濾后水濁度為1ntu左右、周期達14 24小時的好效果。 -
