backwash rate meaning in English

反衡速率

Examples

  1. 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
    中试研究结果表明,粗石英砂滤料上向流过滤比传统的重力流过滤具有更大的含污能力和产水量,为适用较高的反冲洗强度( 21l ( m ~ 2 ? s ) )以便滤料清洗更干净,采用粒径范围为0 . 63 2 . 00mm的粗石英砂滤料,滤层厚82 85cm ,水温6 27 ,进水浊度为30ntu左右等情况下,能获得平均滤速为16 18m h 、平均滤后水浊度为1ntu左右、周期达14 24小时的好效果。
