<p>PROBLEM TO BE SOLVED: To keep the capacity of a deodorizing apparatus well by facilitating the control thereof. SOLUTION: In a microbial deodorizing apparatus circulating water to deodorizing tanks A, B to sprinkle the same to perform deodorizing treatment, the pH of recovered water is measured by activity evaluating devices 9, 19 in water tanks 6, 16 and, from the relation of the measured pHs with preliminarily calculated pH and bacterial activity, the microbial activities in the deodorizing tanks A, B are evaluated. By this constitution, the microbial activities of the deodorizing tanks can be easily evaluated and the maintenance and control of the deodorizing apparatus become easy and the efficiency of the deodorizing apparatus is easily held to a high state.</p> |
