摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating high concentration waste water capable of satisfactorily and stably performing waste water treatment even for high concentration waste water including high concentration organic material and reducing an operation cost by suppressing heating energy to the utmost. SOLUTION: The apparatus for treating high concentration waste water is provided with a methane fermentation anaerobic treatment tank 1 which introduces high concentration waste water 2 and reduces BOD concentration to a first set concentration or below by the methane fermentation, a sulfate reduction type anaerobic treatment tank 5 which introduces waste water 2a of the methane fermentation anaerobic treatment tank 1, degrades organic material in the waste water according to sulfate respiration of anaerobic micro-organism and reduces BOD concentration to a second set concentration or below, an aerobic treatment tank 6 which introduces waste water 2b of the sulfate reduction type anaerobic treatment tank 5, turns BOD concentration into the final BOD concentration by the use of aerobic micro-organism and oxidizes hydrogen sulfide and sulfide in the waste water to obtain sulfate ion and a pipe path 11 which returns final treated water 2c including the sulfate ion obtained in the aerobic treatment tank 6 to the waste water introduction side of the sulfate reduction type anaerobic treatment tank 5.
