NOVELTY - Processing organic waste water, by converting polymeric organic compound sludge into low molecular weight compound, by facultative anaerobes, contacting concentrated liquid pollutant material and aerobic microbe, degrading low molecular weight organic matter to organic acid and alcohol, separating liquid pollutant material into sludge and supernatant, contacting supernatant with aerobic microbes on carrier, degrading supernatant containing organic acid and alcohol into water and carbon dioxide using aerobic microbes, adsorbing decomposition resistant compound.    USE - For processing organic wastewater from milking parlor (both claimed), agricultural farm, livestock, etc.    ADVANTAGE - The pH, biological oxygen demand, and chemical oxygen demand, SS, T-N and T-P can be maintained easily below standard value. There is minimal generation of surplus sludge or bad smell.    DETAILED DESCRIPTION - Processing organic waste water, involves concentrating the isolated organic waste water into a solid pollutant and liquid pollutant material, converting the polymeric organic compounds that exist in precipitating sludge into low molecular weight structural unit, by facultative anaerobes, carrying out aeration and circulation of liquid pollutant material, immobilizing aerobic microbes on a carrier, contacting the liquid pollutant material and aerobic microbe, oxidizing and degrading the low molecular weight structural unit organic matter of the polymeric organic compound contained in the liquid pollutant material, to organic acid and alcohol, separating the concentrated liquid pollutant material into sludge and supernatant, exfoliating from the carrier, contacting the supernatant with aerobic microbes that is immobilized to porous carrier under oxygen enriched conditions, oxidizing and degrading the supernatant containing organic acid and alcohol into water and carbon dioxide using aerobic microbes, continuously performing adsorption and purification of decomposition resistant compound that cannot be oxidized and decomposed by the aerobic microbes on the porous carrier, within an airtight container.
