<p><P>PROBLEM TO BE SOLVED: To provide an excretion treatment apparatus capable of applying aeration to a fluid of excretions more efficiently than before to obtain an aerated fluid of excretions having predetermined characteristics. <P>SOLUTION: First and second aerating tanks 1 and 2 are equipped with output devices 13,14, 34 and 35 for applying aeration to fluids of excretions and defoaming foams generated in the tanks by aeration to output the defoamed fluids of excretions, flow rate sensors 202 and 212 for measuring the flow rates of the defoamed fluids outputted from the output devices 13, 14, 34 and 35 and pH value sensors for measuring the pH values of the fluids of excretions in the first and the second aerating tanks 1 and 2. A controller 8 drives an air feed means on the basis of the values obtained by the flow rate sensors 202 and 212 so as to set the pH values of the first and the second aerating tanks 1 and 2 to desired values. <P>COPYRIGHT: (C)2003,JPO</p> |
