摘要
The present invention relates to a method for reducing the excess sludge and high concentration organic wastewater by the aerobic and anaerobic complex digestion tank and a method for high temperature extinguishing and an apparatus therefor, In the aerobic oxidation tank, heat energy generated in the oxidation process of the organic matter of the high concentration organic wastewater is transferred to the anaerobic digestion tank, It is possible to maintain the proper temperature of the high temperature anaerobic digestion tank by self-heating energy without any external heat source, thereby maximizing the decomposition efficiency of the organic matter, The pressure of the circulation pump of the gas dissolving apparatus in the aerobic oxidizing tank is maintained at about twice the atmospheric pressure to continuously circulate the gas to the inside of the aerobic oxidizing tank to weaken the cell walls and to increase the strength of the cell walls of the microorganisms in the aerobic oxidizing tank Weakened and easily destroyed, The concentration of microorganisms in the anaerobic digestion tank is always maintained at a high level to increase the treatment efficiency by installing a floatation concentration apparatus for solid-liquid separation inside or outside the anaerobic digestion tank. It is possible to reduce the residence time by about 50% as compared with the mesophilic anaerobic digestion so that the digestion tank can be reduced in volume by half and the digestion efficiency can be greatly increased, The initial facility investment cost can be greatly reduced and operation time and maintenance cost can be greatly reduced by reducing the operation time.
