Inactivation of Bacteria in Sewage Sludge by Ionizing Radiation,Heat,and Thermoradiation.

摘要

For purposes of animal feeding or fertilizer usage on edible crops,sewage sludge must be free of pathogenic organisms. Bacterial inactivation by a combination of heat and irradiation is shown to be effective. These results must be viewed in conjunction with those from studies of parasite egg inactivation,virus inactivation,and physical-chemical benefits in order to make a fair assessment of the value of the thermoradiation treatment compared to other possible sludge treatment processes.
