Abstract

Radiation treatment using gamma-rays was investigated in order to reclaim the secondary effluent from a sewage treatment plant. The radiation treatment reduced BOD by 85% irrespective of absorbed dose, and the removals of COD, TOC and color were up to 64%, 34% and 88%, respectively, at a dose of 15 kGy. Gamma-rays effectively disinfected microorganisms and completely removed them at a dose of 0.3 kGy. The combination of gamma-rays and titanium dioxide significantly improved the treatment process. The increases of COD, TOC and color removals were 40%, 10% and 20%, respectively. As confirmed by EPR and the spin-trapping method, this increase was partly caused by the increase of hydroxyl radicals in the presence of titanium dioxide.
