9525059 Waite这是一个支持研究的奖项，其目的是确定用于处理废水和处理系统部件的中间产品的电子束辐射工艺的设计参数。将进行研究的具体例子包括：利用电子束的电离辐射来改变工艺残渣，以改善其在好氧和厌氧消化时的生物降解性；处理厌氧消化器上清液，以改善其生物降解性，并在循环到处理系统中以增加生物处理过程时减少其破坏作用；通过改变其流体性质来改善污泥的脱水性能；以及加速生物稳定过程，如堆肥和土壤注入。该项目包括将于1997年1月与国际原子能机构合作举办的第一期讲习班，以指导进行试验和工程规模的研究。已发现电子束辐射对生活污水处理过程中产生的污泥进行消毒是有效的。被激发的电子束的电离辐射已被证明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，电子束辐射可以在现有的废水处理厂内有效地利用，以提高其他处理系统部件的效率。该项目将利用位于弗吉尼亚州基州迈阿密-戴德污水处理厂的现有1.5 MeV电子束加速器来获得工程设计参数。这种工程规模的操作将以迈阿密大学污染控制技术实验室安装的4MeV直线加速器的试点研究结果为指导。***

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. ***
