THE HYBRID BIOGAS-LIQUID FERTILIZER SYSTEM

摘要

PURPOSE: A hybrid biogas-liquid fertilizer producing system is provided to maintain the proper digestion temperature of an anaerobic tank using a heat source of a self-exothermic aerobic tank. CONSTITUTION: A hybrid biogas-liquid fertilizer producing system comprises the following: a solid-liquid separator(100) separating solid portions from liquid portions of inflowing wastewater; a water storage tank(200) equalizing the concentration and the flow amount of processed wastewater; an anaerobic tank(300) anaerobic-decomposing the processed wastewater, and supplying bio-gas produced from the anaerobic-decomposing process to a generator as an energy source; a self-exothermic aerobic tank(400) supplying heat generated from anaerobic-decomposing organic components of the wastewater to the anaerobic tank; and a liquid-fertilizer storage tank(500).
