БИОГАЗОВАЯ ТЕХНОЛОГИЯ - ЭФФЕКТИВНЫЙ СПОСОБ ПЕРЕРАБОТКИ НАВОЗА СЕЛЬСКОХОЗЯЙСТВЕННЫХ ЖИВОТНЫХ

Abstract

The renewable energy sources (VIE) widespread using makes it possible the fossil fuels’ consumption that pollute the environment reducing significantly. One of the VIE types is biomass, which tends the agricultural production, especially livestock intensification growing. The main type of biomass is manure; at it processing by biogas technology using, it provides biogas, biofertilizer and electric energy, that are necessary for soil fertility and energy supply to rural consumers increasing. At the same time, biogas technology helps the manure disinfection’s problems solving, since fresh manure is an environmental pollutant by harmful gases (methane, ammonia, hydrogen sulfide, etc.) emitting. The livestock methane emissions’ amount is about 16%. The authors have developed small sized biogas manure processing installation, to the small agricultural enterprises’ conditions adapting. Distinctive features of the installation are: sawdust from reed plants for manure preparation loading into the bioreactor; of an external energy source from renewable resources (sun, wind, etc.) to heat the bioreactor in cold weather using; biofertilizer into dry residue and liquid separating; manure different types to carbon and nitrogen at C /N = 20 ratio mixing. These features make it possible the quality of biofertilizer, since reed plants contain vitamins C, carotene, starch, carbohydrates and proteins improving, as well as the crust formation to prevent; of biogas by observing the temperature regime inside the reactor and the ratio C /N = 20 output increasing; manure next fresh portion is accelerated by liquid part feeding of the biofertilizer back into the bioreactor’s process fermentation.
