Abstract

The invention relates to a process for anaerobic fermentation of distillery waste.The process, according to the invention, includes the preliminary neutralization of distillery waste by mixing with an alkaline reagent and subsequent anaerobic fermentation with the production of biogas, at the same time as alkaline reagent for neutralization of distillery waste is used limestone flour, obtained as natural limestone cutting waste, which is mixed with the hot distillery waste with the temperature of 70…90°C up to pH=6…7 in a quantity of 5…20 kg, recalculated to CaO, per 1 m3 of distillery waste. The mixing process is carried out in cavitation mode with continuous agitation, with the subsequent separation of the suspended solids by settling and/or centrifugation. The liquid phase decanted and cooled to the temperature of 33°C is subjected to anaerobic fermentation, which is carried out in expanded and/or fluidized bed of granular particles.
