| 摘要 |
The present invention relates to an autothermal high-temperature acid fermentation tank, and a two-phase anaerobic digestion system comprising the same. The high-temperature acid fermentation tank of the present invention comprises: a fermentation tank main body accommodating wastewater including organic waste inside, and forming a sealed treatment space so as to hydrolyze and acid-ferment organic components in organic materials; a gas circulating part circulating and supplying internal gas produced at an upper part of the fermentation tank main body along with fresh air supplied from outside; an underwater aerator simultaneously combined-spraying and circulating gas and air into the wastewater in the fermentation tank main body so as to produce micro bubbles therein; and a foam breaker stirring a slurry layer of the organic waste contained in the wastewater, and eliminating scum floating on the surface of the wastewater at the same time. |
