Journal AWWA - Enterovirus Removal by a Full-Scale Tertiary Treatment Plant AWWA期刊-通过全尺寸三级处理厂去除肠道病毒
发布日期: 1983-04-01
本文总结了在加利福尼亚州奥兰治县水区21号水厂进行的一项为期四年的研究,其中对肠道病毒进行了监测。水厂21是一个56毫升/天的高级污水处理厂。该工艺包括高pH石灰处理、气提、再碳化、预氯化、多媒体过滤、颗粒活性炭吸附、反渗透脱盐和最终氯化。进水和出水平均每周取样一次。在四年期间,在含氯废水中以极低的水平检测到两种病毒,它们与典型的工厂运行、氯残留组合或高浊度有关。然后对电厂运行标准进行了修改,包括使用下行颗粒活性炭、手动添加氯以及电厂进水来源的变化。 自从这些改变实施以来,没有发现肠病毒的阳性样本。包括9个参考文献、表格、图表。
This paper summarizes a four-year study conducted at Orange County Water District's Water Factory 21 in California, in which enteroviruses were monitored. Water Factory 21 is a 56-ML/d advanced wastewater treatment plant. The process train included high pH-lime treatment, air stripping, recarbonation, prechlorination, multimedia filtration, granular activated carbon adsorption, reverse osmosis demineralization, and final chlorination. The influent and effluent were sampled on the average of once per week. Viruses were detected twice during the four-year period in chlorinated effluents at very low levels and were associated with either a typical plant operations, combined chlorine residuals, or high turbidity. Plant operating criteria were then modified to include use of downflow granular activated carbon, manual addition of chlorine, and the change in the source of the plant influent. Since these changes have been implemented, no positive samples of enteroviruses have been identified. Includes 9 references, tables, figures.
