Abstract

PURPOSE: An apparatus used in sewage treatment plant in which drawing pump is controlled according to the concentration and flow rate of concentrated sludge, sludge of stable concentrations is drawn out with optimum timing, and treatment in the next process is performed effectively.
CONSTITUTION: The sludge 1 and the excess sludge 2 are concentrated, extracted through the pump 4, and measured by the concentration measure 5. Then, a signal is sent to the controller 6 by which as preset concentration signal is received, operating start command is sent to the sludge pump 7. Then, the concentrated sludge is sent to the next process 8. On the other hand, since the treating performance of the sludge treatment process is determined, the amount of sludge drawn is measured by the measurer 9, the integrated amount is calculated by the apparatus 10, and when it reaches more than set value, operating command signal for the pump 7 is stopped.
