Radiation technology for environmental conservation

Miscellaneous:

Abstract

This paper reviews research and development of radiation technology application for environmental conservation. Our group in cooperation with Ebara Mfg. co., Ltd. first found and studied removals of sulfur dioxide and nitrogen oxides from flue gases by electron beam irradiation. Most of sulfer dioxide and nitrogen oxides are converted to ammonium sulfate and nitrate by radiation with the addition of ammonia. Feasibility studies of this technology by pilot scale experiments have been carried out in Japan, USA and Germany for flue gases from iron-ore sintering furnace and coal fire power station. About 90 % of CO{sub 2} and NO{sub X} are removed with 15 kGy. Organic pollutants in wastewater, drinking water and ground water have been found to be reduced by radiation technology. Synergetic effect of radiation and ozone to remove pollutants was also found. Disinfection of water effluent from sewage water treatment plant by radiation instead of using chlorine to avoid formation of chlorinated organic compounds has been studied by our group. Efficient composting of sewage sludge using radiation disinfection followed by fermentation has been developed and produced compost can be used as fertilizer. In conclusion, radiation technology can provide new efficient treatment method for wastes. (author).
