Source and Fate of Particles in Wastewater and Sludge Treatment Facilities

9312825迪克这是一个为研究提供支持的奖项，其目的是确定废水和相关处理过程中出现的细颗粒的来源和去向，作为改进过程设计和操作以控制这些排放的第一步。研究人员计划开发程序，对进入该过程的颗粒物进行标记，并追踪它们在组成废水处理系统的各种单元操作中的路径。追踪将被调查的颗粒物的技术包括中子激活、荧光标记、放射性标记、元素和化学分析、颗粒尺寸测量和显微镜检查。该项目的结果预计将比目前更好地了解废水中存在的细颗粒和处理过程中产生的细颗粒的去向。这一更好的认识反过来可望为改进废水处理工艺和系统的工程设计和操作以及管理这些处理工艺产生的剩余淤泥提供基础。

9312825 Dick This is an award to provide support for research, the objective of which is to determine the source and fate of fine particles emerging from wastewater and associated treatment processes as an initial step toward improved process design and operation to exercise control over these discharges. The investigator plans to develop procedures for tagging particles that enter the process and tracing their path through the various unit operations that comprise a wastewater treatment system. Techniques for tracking the particles that will be investigated include neutron activation, fluorescent marking, radiolabeling, elemental and chemical analyses, particle size measurement and microscopic examination. Results of this project are expected to provide a better understanding than now exists for the fate of fine particles that are present in wastewater and those produced during the treatment processes. This improved understanding in turn is expected to provide the basis for improvement of engineering design and operation of processes and systems for wastewater treatment and for managing the residual sludges derived from these treatment processes.
