Methane fermentation treatment method for high concentration organic wastewater and methane fermentation tank for carrying out the same

摘要

The present invention relates to a methane fermentation method for treating a high concentration organic wastewater with an anaerobic microorganism and a methane fermentation tank for carrying out the method. The granular activated tannadia layer (3) is provided around the dispersing device (2) The sludge blanket forming space 4 is provided between the mediator layer 3 and the first layer separating means 5 and the primary separating means 5 is provided in the intermediate portion of the fermentation tank, It is possible to prevent the microorganisms from being overloaded at the inlet of the fermentation tank and maintaining a high concentration in the tank and to prevent the organic wastewater from being secondarily The anaerobic fermentation treatment not only improves the treatment efficiency but also ensures the prevention of inflow of sludge and gas into the treated water channel, thereby achieving the safety of treated water.
