| 中文摘要 |
| 本文提出了以固定混合器作为促进混合效果装置的快速混合法,并以E. Coli作为指示微生物、液氯作为消毒剂进行了研究。结果表明,均匀快速而剧烈的初始混合作用,可大大改善灭菌效果。在短至5秒的接触时间内即可达到99.99%以上的灭活效率。投氯量和接触时间对E. Coli灭活率的影响随混合程度的提高而减弱。与传统法相比,灭活率可提高100倍以上,投氯量可下降4—8倍,接触时间可大大缩短。 |
| 英文摘要 |
| Rapid Mixing chlorination process for water disinfection was developed with astatic mixer as the mixing device. Experimental results show that inactivation of E. Coli, which was chosen as the indicator of disinfection, by chlorine can be greatly improved by initial rapid strong mixing. 99.99% of E. Coli Killing efficiency can be obtained within 5 sec. of contact time. Effects of chlorine dosage and contact time on inactivation efficiency become less important with the increase of mixing strength. Compared with traditional chlori-nation processes, this method is 100 times more effective. In addition, both chlorine dosage and contact time Can be greatly decreased. |
