9525059 Waite This is an award to support research, the objective of which is to determine the parameters for design of electron beam radiation processes to treat wastewater and intermediate products of treatment system components. Specific examples of research to be investigated include use of ionizing radiation of the electron beam for modification of process residuals to improve their biodegradability when subjected to aerobic and anaerobic digestion, processing of anaerobic digester supernatant fluids to improve their biodegradability and to reduce their disruptive effect when recycled to the treatment system for additional exposure to biotreatment processes, improvement of sludge dewaterability by modification of their fluid properties and acceleration of biostabilization processes such as composting and soil injection. The project involves an initial workshop to be conducted in January of 1997 conducted in cooperation with the International Atomic Energy Agency for guidance in conduct of the pilot and engineering-scale research. Electron beam radiation has been found to be effective in disinfection of sludges produced during treatment of domestic wastewater. The ionizing radiation of a beam of energized electrons has been shown to be effective in destruction of organic compounds of pollutional significance. Indications are that electron beam radiation could be utilized productively within existing wastewater treatment plants to improve the efficiency of other treatment system components. This project will utilize an existing 1.5 MeV electron beam accelerator located at the Miami-Dade Wastewater Treatment Plant on Virginia Key to obtain engineering-design parameters. This engineering-scale operation will be guided by results from pilot-scale research using a 4 MeV linear accelerator being installed at the University of Miami's Laboratory for Pollution Control Technologies. ***

小行星9525059 这是一个支持研究的奖项，其目的是确定电子束辐射工艺设计的参数，以处理废水和处理系统组件的中间产品。 研究的具体例子包括：利用电子束的电离辐射对工艺残留物进行改性，以改善其在需氧和厌氧消化过程中的生物降解能力;处理厌氧消化池上清液，以改善其生物降解能力，并减少其在再循环到处理系统以进一步暴露于生物处理过程时的破坏性影响;通过改变污泥的流体性质和加速堆肥和土壤注入等生物稳定化过程来改善污泥的脱水性能。 该项目包括与国际原子能机构合作于1997年1月举办一个初步讲习班，以指导进行试点和工程规模的研究。 已发现电子束辐射在对生活污水处理过程中产生的污泥进行消毒方面是有效的。 已经证明，一束高能电子的电离辐射在破坏具有污染意义的有机化合物方面是有效的。 有迹象表明，电子束辐射可以有效地利用现有的废水处理厂，以提高其他处理系统组件的效率。 该项目将利用现有的1.5兆电子伏电子束加速器位于迈阿密戴德污水处理厂弗吉尼亚州的关键，以获得工程设计参数。 这一工程规模的操作将由使用安装在迈阿密大学污染控制技术实验室的4 MeV线性加速器进行的中试规模研究的结果指导。***
