METHOD FOR PREPARING PREPARING A BIRD'S LITTER FOR ITS USE IN THE COMPOSITION OF MULTI-COMPONENT LOADING MATERIALS OF ONE-CHAMBER BIOGAS INSTALLATION (BSU)

摘要

The method of preliminary preparation of bird droppings for its subsequent use as part of a multicomponent feedstock of a single-chamber biogas plant, including microbiological treatment of bird droppings and the introduction of bioadditives in liquid form, the implementation of biological heating and fermentation of the mixture, characterized in that 20- effluent is used as a bioadditive 25% of the total weight of bird droppings, which includes mineral fertilizers - N: P: K in an amount of 0.1: 0.16: 0.18%, respectively, and native microflora with a density of microorganisms of 260 × 10 CFU / ml, after which the resulting substrate is aged for 7-9 days under anaerobic conditions, and then fed to the reactor of the biogas plant in the amount of 15% of the loading mass.
