HIGH RATE METHANC PRODUCTION SYSTEM USING ANAEROBIC ARCHAEA

摘要

A high efficiency livestock wastewater treating digestion system which improves removal efficiency of organic matters and improves recovery ratio of methane by separating a single UASB(upward-flow anaerobic sludge blanket) reactor into two phases of a hydrolysis/acid generating reactor and a methane generating reactor in an anaerobic digestion of high concentration livestock wastewater, and a high efficiency livestock wastewater treating digestion method using the same are provided. A high efficiency livestock wastewater treating digestion system comprises: a hydrolysis/acid generating reactor(100) into which raw livestock wastewater flows through a raw water inflow pipe(101); an agitator(102) installed in the hydrolysis/acid generating reactor to generate an organic acid solution by smoothly contacting raw livestock wastewater with microorganisms; a retention tank(200) for storing the organic acid solution for a short time and flowing the organic acid solution into the methane generating reactor by a metering pump(510); a methane generating reactor(300) for finally generating methane gas using an organic acid generated in the hydrolysis/acid generating reactor and discharging the organic acid solution through a discharge pipe of the methane generating reactor; a gas collector(302) for collecting the generated methane gas; and an anaerobic archaea injector(400) installed at an inlet part of the methane generating reactor to maximize the generation of methane gas by quantitatively injecting archaea into the methane generating reactor.
