摘要

PROBLEM TO BE SOLVED: To maintain the oxygen concentration in a treatment tank at a suitable level for the activity of microorganisms in the decomposition treatment of waste by the use of microorganisms. SOLUTION: This treatment equipment is provided with an air supplying means for supplying an air into the treatment tank 3 and an oxygen sensor 21 for detecting the concentration of oxygen in the treating tank 3. The concentration of oxygen in the treatment tank 3 is detected by the output of this oxygen sensor 21, thereby controlling the air supplying means and maintaining the inside of the treatment tank 3 at a prescribed oxygen concentration level.
