摘要：The use of electron beam to disinfect sewage water is gaining importance. The current problem on environmental health in relation to water pollution insists for the safe disposal of sewage water. In general, sewage water comprises of heterogeneous organic based chemicals as well as pathogens. EB (electron beam) treatment of the wastewater was found to be very effective in reducing the pathogens as well as organic load. EB dose of 1.5 kGy was sufficient for complete elimination of total coli forms. The experimental results elucidated that the reduction of biological oxygen demand (BOD) (30.38 and 51.7%) in both inlet and outlet sewage samples. Similarly, reduction of chemical oxygen demand (COD) was observed (37.54 and 52.32%) both sewage samples with respect to increasing of irradiation doses (0.45 to 6 kGy). The present study demonstrated the potential of ionizing radiation for disinfection of sewage and to increase the water quality of the wastewater by decreasing BOD and COD. So, the irradiation sewage water can find its application either in agriculture for irrigation or in industry sector for cooling purpose or in both the sectors.Keywords:Disinfection, electron beam accelerator, organic matter, sewage water quality
