FIELD: agriculture and municipal economy.
SUBSTANCE: the invention is intended for use in agricultural and municipal economy for a fermentation of solid non-ground organic waste materials of cities and settlements as well as a dung and droppings of cattle-breeding and poultry farms, a vegetable wastes of agricultural production, different organic waste materials of agricultural estates and country houses with production out of them of the high-quality fluid mineralized organic fertilizers decontaminated from the pathogenic microflora, helminths, their eggs and seeds of weeds and with a high share of humus and a combustible biogas used for power needs. Fermentation of solid organic waste materials without their grounding and sorting is realized in a separately enclosed with a perforated fence sour zone of the first phase of the anaerobic fermentation with use of products of their splitting/hydrolyzing/in the second phase of an alkaline fermentation with formation in it of the liquid mineralized organic fertilizers and a combustible biogas, which is used before its withdrawal from the methane tank for stirring of fermentable waste products in it. At the side of the methane tank in its upper part there is a demountable drag-chain elevator, two horizontally located one over another and counter-directionally operating branches of which have a perforated fence located between and outside them and are introduced into the throat. The technical effect is provision of full disintegration of the waste products and formation of both a combustible biogas used for the power needs and the liquid mineralized organic fertilizers being more efficient, than a dung of animals and droppings of hens.
EFFECT: the invention ensures full disintegration of the waste products and formation of both a combustible biogas used for the power needs and the liquid mineralized organic fertilizers being more efficient, than a dung of animals and droppings of hens.
