本powerpoint演示文稿首先简要概述了亚利桑那州斯科茨代尔市水处理厂，重点介绍了水回收厂（WRP）和高级水处理设施（AWT）。潜在问题化合物（CPC）包括:该市监测的40多个CPC；一种化合物被确定为优先 污染物为N-亚硝二甲胺（NDMA），基于CDPH 10纳克/升的公共通知水平。AWT的扩建包括:目前正在设计扩建至20毫克/日 进行中的评估NDMA的发生和 实施NDMA缓解策略，包括流程优化和附加处理流程。本文介绍了全尺度采样结果、WRP和AWT工厂概况以及其他水质参数的影响。 提供了台架试验结果，以及氯氨比、预氯胺化、游离氯接触时间和pH值。给出了全尺寸试验的总结，包括试验的游离氯接触时间=5-15分钟 在添加氨之前，NDMA的形成量大大减少 （75%）不超过TTHM限值。包括表格，数字。

This powerpoint presentation begins by providing a brief overview of the City of Scottsdale, Arizona Water Campus, specifically focusing on the water reclamation plant (WRP) and the advanced water treatment facility (AWT). Compounds of potential concern (CPC) include: more than 40 CPCs monitored by the City; one compound identified as priority contaminant is N-Nitrosodimethylamine (NDMA), based on CDPH public notification level of 10 ng/L. Expansion of AWT includes: design of expansion to 20 mgd is currently underway; and, evaluate the occurrence of NDMA and implement NDMA mitigation strategies, including process optimization and additional treatment processes. Full scale sampling results are presented, along with WRP and AWT plant profiling and the impact of other water quality parameters. Bench scale test results are provided, along with chlorine to ammonia ratio, preformed chloramination, free chlorine contact time, and pH. A summary of full scale testing is presented, including free chlorine contact time tested = 5 -15 min prior to ammonia addition, and the formation of NDMA was substantially reduced (75%) without exceeding TTHM limits. Includes table, figures.
