2 . 0快滤技术的引进 |
| 2. | Removal of anionic surfactant in artificial rapid infiltration land treatment system
在人工快滤系统中的去除 |
| 3. | Fast filtration also performed better than slow filtration at purification
对于浊度的去除，快滤法亦较慢滤法为佳。 |
| 4. | The biggest difference between the slow and rapid filtration methods was in their speed
快滤法与慢滤法最主要的差别在于过滤的速率。 |
| 5. | At that time the water companies of many developed countries also began building rapid filtration plants
当时各先进国家的自来水事业，也纷纷兴建快滤场。 |
| 6. | The rapid filtration plant had a filtration speed of over 100 meters per day , taking only 2 hours to turn raw water into clean water
快滤场每日滤速在100公尺以上，原水变成清水约需2 - 4小时。 |
| 7. | Since then all of our departments new water purification facilities have used rapid filtration technology , providing the water supplies of our precincts with dependable sources of clean water
尔后本处新增之净水场悉数采用快滤技术，为辖区供水提供坚实可靠的基础。 |
| 8. | Compared with conventionally rapid filter , upflow filtration is a more sensible filter method , which is characterized by large capacity for storage of solids , small head loss and long filter run
上向流过滤是一种理想的过滤方式。与传统快滤池相比具有滤层截污量大，水头损失小，过滤周期长等特点。 |
| 9. | Abstract : the effects of adding purifying agent during the process of water purification were studied . the best opportunity for applying purification agent to water during purification process was obtained
文摘:对水质净化过程中投加净化剂的效果进行了研究，得出了在冬春低温低浊季节，水力循环澄清池-快滤池净化过程投加净化剂脱混的最佳选择。 |
| 10. | Through sedimentation , filtration and disinfection , the process of turning raw water into clean water required around 48 hours . though the filtration speed was slow , it provided a stable quality of water until its later replacement by faster working rapid filtration plants
原水经沉淀过滤消毒，最后变成清水，约需48小时，费时虽长，却能供应水质稳定的自来水，日后已被滤速更快的快滤场取代。 |
