Abstract

The results are presented of the work on intensification of anaerobic treatment of multi-component waste waters from fermentation processes, on efficiency increasing of winery grain biochemical treatment, with the obtaining of solid precipitates to be used as protein-vitamin additive for cattle feeding. These scopes are reached due to the preliminary photocatalytical treatment of grain with the system [Co(III)/Co(II)/H2O2/UV]. Under the UV-irradiation, the photocatalytical hydrolysis of refractory polyphenol compounds occurs in treated winery wastes. On further stage, under anaerobic conditions, efficiency of wastewater treatment is thus increased. On the metanogenesis stage, this ensures an enhanced yield of biogas and active sludge formation with high contents of cyanocobalamine (vitamin В12) which is a biologically active substance
