METHOD OF PROCESSING ORGANIC WASTES AND TECHNOLOGICAL LINE FOR PERFORMING THE SAME Russian patent published in 1994 - IPC

FIELD: procession of organic wastes, such as manure, bird excrement, straw, haulm, woody fibers, saw ducts, lignin, for producing fertilizer, forage additives, soils for growing mushrooms and seedlings in greenhouse conditions. SUBSTANCE: method comprises steps of processing organic wastes in biological reactors with use of stages of charging, heating up and fermentation of waste materials. Charging is being performed successively at least every other biological reactor from the last reactor, had been charged. Heating up of initial waste mass is being performed by contact-type supply of heat from other reactors through their common walls and through rear wall along an air duct. Technological line has at least two rows of biological reactors for fermentation of wastes, each reactor is provided by apertural tubes for aeration, mounted in a base. Each reactor also has a four-angle form with a ratio of its base width to its base length, equal to 1:(1.0-1.6). The biological reactors are arranged successively in such a way, that each previous reactor has a common wall with next reactor along their large side. The air duct is provided between the rows of the reactors along their rear wall. EFFECT: lowered energy consumption due to complete usage of heat of exothermic reaction of fermentation process for heating up the initial biomass in the reactor. 3 cl, 1 dwg
