CO-LANDFILL ANAEROBIC BIOREACTOR SYSTEM

PURPOSE: A biogas production device through a landfill anaerobic bioreactor is provided to increase productivity of LFG while improving reaction efficiency and reaction speed of methane generation, and to increase the amount of acid fermentation biomass. CONSTITUTION: A biogas production device through a landfill anaerobic bioreactor includes an acid fermentation part(10), a bioreactor(20), a spray amount controlling part(30), a landfill gas processing part(40), and a leachate recirculation part(50). The acid fermentation part includes an acid fermentation tank(11), an agitator(12), and an agitating vane(15). The agitating vane mixes organic waste(1) of the acid fermentation tank. The bioreactor includes a landfill(21), a cover(22), a gas collecting pipe(23), a valve(26), and gravel. The spray amount control part includes an injection pipe(31) and an acid fermentation liquid pump(33). A plurality of injection holes(32) are formed on an outer circumference of the injection pipe.
