Inactivation of Waterborne Microorganisms by a High-Energy Electron Beam: A Large Scale Study 高能电子束灭活水性微生物的大规模研究
发布日期: 1999-08-29
研究了高能电子束对水性微生物的影响。电子束技术已被广泛应用于生物、医学、化学和物理等领域。作为一种水处理技术,电子束对环境友好,不产生有毒废物或残余辐射,而且非常节能。这项电子束研究是在佛罗里达州迈阿密的弗吉尼亚基污水处理厂进行的大规模研究。初步研究表明,电子束剂量为500克拉时,大肠杆菌噬菌体和总大肠菌群的废水数量减少了3 log[10]。这项研究显示了类似的失活。水动力试验表明,4-6微米的乳胶球均匀分布在4000加仑脱氯自来水中。在400克拉时,观察到terrigena克雷伯氏菌和PRD1沙门氏菌噬菌体的失活率分别为4.01和4.74 log[10]。 这项研究的初步结果表明,电子束技术可用于水处理,以减少活微生物的数量,并可用于常规水处理。包括13个参考文献、表格、图表。
A study was undertaken to examine the effect of a high-energy electron beam on waterborne microorganisms. Electron beam technology has been used for a wide variety of applications, including biological, medical, chemical and physical. As a water treatment technology, electron beams are environmentally friendly, produce no toxic wastes or residual radiation, and are very energy efficient. The electron beam study was conducted on a large scale at the Virginia Key Wastewater Treatment Plant, Miami, Florida. Preliminary studies suggested that a wastewater population of coliphage and total coliforms were reduced by 3 log[10] at an electron beam dose of 500 krads. This study showed a similar inactivation. Hydrodynamic tests showed that 4-6 um latex spheres were homogeneously distributed in 4,000 gallons of dechlorinated tap water. At 400 krads, 4.01 and 4.74 log[10] inactivations for Klebsiella terrigena and PRD1 Salmonella phage were observed, respectively. The preliminary findings of this study suggest that electron beam technology can be used to treat water to reduce the number of viable microorganisms, and may have application for routine water treatment. Includes 13 references, table, figures.
