Disinfection Using High-Intensity Pulsed-Ultraviolet Irradiation 高强度脉冲紫外线消毒
发布日期: 1998-01-01
本研究展示了脉冲紫外辐射分批和流动实验的结果。进行了以下实验:证明异养平板计数(HPC)细菌和雄性特异性(MS-2)大肠杆菌噬菌体的消毒效率;提供初始消毒副产品(DBP)生产结果;并确定脉冲紫外线的近似全尺寸运行成本。在批量试验中,发现脉冲紫外线很容易使自然产生的HPC细菌失活(>4-log失活)。MS-2暴露于脉冲紫外线导致>8对数失活。流动水测试——模拟水在全尺寸运行期间非常接近闪光灯的情况——显示醛类和羧酸(从48%增加到1132%)以及可生物降解的溶解有机碳(BDOC)(从53%增加到119%)。一个完整项目的平均运营成本(不包括耗材的维护或更换)- 计算得出,能够以至少2.4 log MS-2大肠杆菌噬菌体失活处理0.72立方英尺每秒(cfs)的规模单位为每英亩英尺6.58美元。
This study presents results from batch and flowing experiments with pulsed-UV radiation. Experiments were conducted to: demonstrate disinfection efficiency with heterotrophic plate count (HPC) bacteria and male-specific (MS-2) coliphage; provide initial disinfection byproducts (DBP) production results; and, determine approximate full-scale operating costs for pulsed UV. In batch tests, pulsed UV was found to easily inactivate naturally occurring HPC bacteria (>4-log inactivation). Exposure of MS-2 to pulsed UV resulted in >8-log inactivation. Flowing water tests - simulating water passing extremely close to the flash lamp during full-scale operation - showed increases in aldehydes and carboxylic acids (from 48 to 1,132 percent) and biodegradable dissolved organic carbon (BDOC) (from 53 to 119 percent). The average operating costs (not including maintenance or replacement of consumable items) for a full-scale unit that could treat 0.72 cubic feet per second (cfs) with a minimum 2.4-log MS-2 coliphage inactivation were calculated to be $6.58 per acre-foot.
