PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating waste water, in each of which utilization of a bacillus can be maximized in waste water biological treatment while retraining a treatment cost to the minimum.SOLUTION: The method for treating waste water comprises a step of introducing organic matter-containing waste water into a treatment tank 2 so that the organic matter-containing waste water is treated biologically by using the bacillus preferentially. In the concrete, the method for treating waste water comprises the steps of: measuring the enzyme activity 13 which is derived from the bacillus contained in the waste water in the treatment tank 2; and controlling the biological treatment based on the measured enzyme activity.SELECTED DRAWING: Figure 1 |
