Abstract

PURPOSE: To carry out sewage treatment stably by constituting the titled apparatus from an operator for a return sludge concn. and an accumulated amount of activated sludge in a final precipitation basin and a controller calculating an operation deviation amount of a return sludge amount to keep treatment effect due to the activated sludge high.
CONSTITUTION: Concentrated sludge precipitated in a precipitation basin is collected in a hopper 5 by a scraper 4 and sludge withdrawn through a withdrawing pipe 6 is stored in a sludge storage tank 8. A signal measured by a flow meter 2 and a MLSS meter 13 in an aeration tank is sent to a first operator 14 for calculating a return sludge concn. and a precipitation basin sludge accumulation amount. A first controller 15 for adjusting a return sludge flow amount from deviation of the value of the precipitation basin sludge accumulation amount calculated by the first operator 14 and an objective value thereof and a second controller 16 for adjusting the return sludge flow amount so as to minimize deviation from an indication value of the MLSS meter of the aeration tank and a set value thereof are installed.
