本powerpoint演示文稿首先简要概述了康特拉科斯塔水区的一个项目:评估select的处理效果 污水处理中试技术 去除微量有机化合物，包括 NDMA， EDC， PPCP，以及 农药；和 评估随后形成的 管制和非管制消毒 台式研究中的副产品。实验计划包括文献回顾和筛选取样、处理技术测试、中试设置和测试、第1列和第2列——臭氧氧化和生物降解 过滤（5gpm）；第3列——NF膜 （20 gpm）。总结和结论如下: 为了理解这个问题，研究已经完成 现有治疗的有效性 流程和高级（未来） 微量有机物技术； 微量有机化合物的选择 发生时，之前的研究，以及 模型表示； 已完成试点研究，以评估 臭氧+BAF， 臭氧/过氧化氢+BAF，以及 NF；结果表明，臭氧能有效地去除臭氧 （e90%）大多数化合物在1mg/L臭氧剂量下； 较低的臭氧剂量可在一定程度上去除臭氧 微量有机物； 抗臭氧化合物 以前的研究； 臭氧/过氧化氢没有提供额外的保护 与单独使用臭氧相比，去除效果更好；和 NF有效去除了微量有机物，但去除了卤水 必须处理/处置。包括表格、数字。

This powerpoint presentation begins by providing a brief overview of a project by the Contra Costa Water District to: evaluate treatment efficacies of select treatment technologies at pilot scale for the removal of trace organic compounds, including NDMA, EDCs, PPCPs, and pesticides; and, to evaluate subsequent formation of regulated and unregulated disinfection byproducts in a benchtop study. The experimental plan included a literature review and screening sampling, testing of treatment technologies, pilot setup and testing, Trains 1 and 2 - Ozonation and Filtration (5 gpm); and, Train 3 - NF Membranes (20 gpm). Summary and conclusions indicate the following: research completed to understand the effectiveness of existing treatment processes and advanced (future) technologies for trace organics; trace organic compounds selected based upon occurrence, previous studies, and model representation; pilot study completed to evaluate ozone + BAF, ozone/peroxide + BAF, and NF; results show that ozone effectively removes (e90%) most compounds at 1mg/L ozone dose; lower ozone dose provides some removal of trace organics; ozone resistant compounds common to previous studies; ozone/peroxide did not provide additional removal as compared to ozone alone; and, NF effectively removed trace organics, but brine must be treated/disposed.
