Abstract

PURPOSE: To avoid an increase of equipment cost and to give a fixed head in descent flowing passage, by controlling to shut the opening and shutting value only when detected value of pressure in closed duct is higher than a set up value.
CONSTITUTION: The apparatus 15 detecting the inner pressure of closed duct passage of upper stream side from connected place of the pipe 5 for the closed duct passage C, is equipped and the control mechanism 16 is provided for putting the opening and shutting valve 14 in closed state automatically and reversively based on the information that the pressure detected value by the pressure detection apparatus 15 is higher than the set up value. The oxygen contained gas supply flowing passage 11 is connected with the upper side of the down flowing passage A and the water to be treated containing activated sludge, is circulated extending over the up and down flowing passages A, B and the passage C. The flowing passage for gas discharge D, is shut based on the pressure rise at the passage C at the ascending time of the water to be treated in the pipe 6 when the level of the water to be treated is raised accompanied by the load fluctuation and gushing of the water to be treated is eliminated.
