Abstract

The rational technology biotreatment of agricultural waste, including next operations: pre-preparation of raw materials, acid stage fermentation of the substrate and alkaline stage was developed. Advantage is manifested in the fact that in each phase are optimal conditions for the development and life activity of the microbial population, which is necessary to improve the efficiency of fermentation of biomass. The biogas plant with a double – chamber bioreactor was developed, scale tests conducted and their results were shown. A method of calculating the basic parameters of the technological equipment for processing waste were developed.
