Abstract

Gamma-irradiation of treated piggery slurry was studied as a possible way of posttreatment. Biologically non-degradable substances (cellulose, lignin, etc.) were almost completely oxidized at 90–100 kGy radiation doses. TOC values indicated complete oxidation of organic carbon to CO2. Radiation doses of 10 and 50 kGy have not changed the biodegradability of irradiated substances. By γ-irradiation after chemical and biological treatment it is possible to get highest quality effluent with COD values lower than 40 mg.l−1.
