Radiation treatment of urban wastewater and drinking water by electron beam

In this study, the microbe's pollution of sewage, wastewater and several wells around Yazd were measured. Our study includes counting aerobic mesophilic bacteria, Coliforms and E.coli. Then the microbial resistance of the sample to ray was determined as D10 value and the optimum dose obtained to meet the desired level of pollution and disinfection the wastewater. Also, Salmonella detection tests before and after irradiating was performed on the samples. We were used irradiation method by Electron beam to decrease bioburden. Also BOD and COD of wastewater were measured and shown that BOD and COD were been decreased after irradiation regularly.
