Presidential Young Investigators Award: Characterization andRemoval of Recalcitrant Organic Matter From Water

该奖项旨在支持对水中有机污染物的表征和去除的研究，这些污染物难以通过用于处理人类消费用水的常规水处理工艺去除。本项目正在进行的研究包括对未通过使用或不使用臭氧的混凝、沉淀和过滤去除的有机物质的化学特性，以及确定去除残余有机物质的最佳物理/化学过程系统，包括可能的臭氧中间处理。高级氧化、离子交换和吸附工艺。由这位总统青年调查员发起的研究涉及与处理受污染的地表水和地下水的过程有关的问题，以使它们可供人类消费。常规的物理和化学处理工艺不能去除可能通过化学消毒转化为有害物质的有机物。这项研究的结果很可能用于系统的工程设计，以产生比现在更可接受的质量的水。

This is an award to support research on the characterization and removal from water of organic pollutants that are recalcitrant to being removed by conventional water treatment processes used to treat water destined for human consumption. Research being conducted in this project involves the chemical characterization of organic matter not removed by coagulation, sedimentation and filtration with and without the use of ozone and determination of the best physical/chemical process-system for removal of the residual organic matter including possible intermediate treatment with ozone, advanced oxidation, ion exchange and adsorption processes. Research being initiated by this Presidential Young Investigator addresses a problem associated with the processes of treating polluted surface and groundwaters to make them acceptable for human consumption. Conventional physical and chemical treatment processes may not remove organic substances that may be converted into harmful substances by chemical disinfection. Results of this research are likely to be utilized in engineering design of systems to produce water of more acceptable quality than is now possible.
