Bromate Control During Ozonation of High-Bromide Drinking Water 高溴饮用水臭氧氧化过程中溴酸盐的控制
发布日期: 2002-11-01
本研究的目的是防止德克萨斯州埃尔帕索市的Jonathon Rogers水处理厂的溴酸盐浓度超过10 ppb MCL。进行了实验室和全植物研究。在实验室规模上,以1.0、1.5和2.0升/分钟的速度对两升原水进行臭氧氧化,时间从1分钟到10分钟不等。在每个时间间隔测量臭氧浓度,并分析相应样品中的溴酸盐。在工厂规模上,在处理过程中的不同点采集样本,包括臭氧接触器的进水和出水,并分析臭氧和溴酸盐。 这是在设计流量的35%到110%之间的工厂流量下进行的(以确保对大范围的滞留时间进行评估)。包括3个参考文献、表格、图表和附录。
The objective of this study was to prevent the bromate concentration from becoming greater than 10 ppb MCL at the 40 MGD Jonathon Rogers Water Treatment plant in the City of El Paso, Texas. Both laboratory and full plant studies were conducted. At the laboratory scale, two liters of raw water were ozonated at 1.0, 1.5, and 2.0 L/min for times ranging from 1 to 10 minutes. The ozone concentration was measured at each time interval and the respective samples were analyzed for bromates. At the plant scale, samples were collected at various points in the treatment process, including at the influent and effluent of the ozone contactor, and analyzed for ozone and bromates. This was done at plant flow rates ranging from 35% to 110% of the design flow rate (to insure that a wide range of detention times would be evaluated). Includes 3 references, tables, figures, appendices.
