The treatment of mixed wastes presents numerous problems for the generator as well as for anyone interested in site remediation largely due to its classification as both a radiological and hazardous waste. The goal of this project was to develop a treatment process that could be used to destroy the hazardous organic compounds in a continuous stream of low-level mixed waste. Once the toxic organic compound(s) is destroyed, the waste would be classified only as a radiological waste and could be treated using known technology. Electron beam irradiation has proven to be an effective technology for removing hazardous organic compounds in aqueous streams. The removal results from the action of highly reactive chemical species (OH{center_dot}, e{sup {minus}}{sub aq}, H{center_dot}) generated when high energy electrons penetrate water. Since e{sup {minus}}{sub aq} and H{center_dot} are reducing radicals and OH{center_dot} is an oxidizing radical, the process is effective against a wide range of individual organic compounds as well as mixtures of compounds commonly found in low-level mixed waste. Pilot scale (100 gpm) studies, on simulated low-level mixed waste, were conducted at the Electron Beam Research Facility (EBRF) located in the Central District Wastewater Treatment Plant in Miami, Florida. The electron beam system used for these studies utilizes a 1.5 MeV, 50 mA continuous beam accelerator. This paper will present a brief overview of the technology, and selected results from the simulated low-level mixed waste experiments.
