本文报告在不耗氯介质中几种肠病毒(脊髓灰质炎1、2型,克萨奇B5,埃可12)和f2大肠菌噬菌体的氯消毒实验结果。病毒经过超速离心纯化;投氯剂量范围在2～12毫克萨升之间,接触0.5～60分钟间测定残留病毒量及各种余氯量。结果表明,肠病毒中以克萨奇B5抵抗力最强,以下依次为脊髓灰质炎2、1型、埃可12。这一结果与Liu等报告中的实验结果不同而与其以一级反应的计算结果相似。与文献相比,灭活99％病毒所需加氯剂量以本实验为最低,表明本实验条件下揭示出的是或接近是病毒本身对氯的抵抗力,没有受其它耗氯物质的干扰。
This article reports the result of chlorine disinfection of several enteroviruses (poliomyelitis type 1, type 2, saxophone B5, echoes 12) and f2 coliforms in non-chlorinated media. The virus was purified by ultracentrifugation; the dosage range of dosing chlorine was between 2 and 12 milligrams, and the remaining virus and all kinds of residual chlorine were determined after 0.5 to 60 minutes of exposure. The results showed that Enterobacteriaceae B5 was the most resistant to Enterovirus, the following were polio 2,1 type, Eke12. This result is similar to the one calculated by the first-order reaction, which is different from the experimental results in the Liu et al. Report. Compared with the literature, the amount of chlorination required to inactivate 99% of the virus is the lowest in this experiment, indicating that the virus itself is at or near the resistance of the virus to chlorine and is not disturbed by other chloride-depleting substances.
