摘要
PROBLEM TO BE SOLVED: To provide an anaerobic fermentation method of waste water, a microorganism carrier for the anaerobic fermentation, and an anaerobic fermentation treatment apparatus, enabling excellent water quality to be obtained only by the anaerobic fermentation.SOLUTION: The anaerobic fermentation method of waste water is provided in which waste water 14 is supplied from a position of a reaction tank 12 lower than a fixed filter bed 22 disposed inside the reaction tank 12 and treated water 18 is discharged from an upper portion of the reaction tank 12 while treating the waste water 14 by anaerobic fermentation with a sludge composed of microorganism in the reaction tank 12. In the anaerobic fermentation method of waste water, the treated water 18 is solid-liquid separated to recover the sludge and the sludge is solidified to form a microorganism carrier 46, followed by disposing the microorganism carrier 46 on an upper portion of the fixed filter bed (fixed filter bed 22a).SELECTED DRAWING: Figure 1
