PURPOSE: A facultive anaerobic hydrolysis/acid-fermentation and anaerobic digestion apparatus of a spiral structure is provided to improve the mixing efficiency of anaerobic microorganisms by preventing the non-uniform mixing of hydrolyzing materials. CONSTITUTION: A facultive anaerobic hydrolysis/acid-fermentation and anaerobic digestion apparatus of a spiral structure includes a hydrolysis and acid-fermentation bath(100) and an anaerobic digestion bath(200). The upper side of the hydrolysis and acid-fermentation bath is opened. The anaerobic digestion bath is air-tightened. Spiral ascending water channels(133, 233) are formed in the hydrolysis/acid-fermentation bath and the anaerobic digestion bath. The spiral ascending water channels expands the surface area of sludge to accelerate the hydrolysis and acid-fermentation of organic materials and the anaerobic fermentation of organic materials contained in the sludge. The sludge is transferred along the spiral ascending water channels. |
