<p>PURPOSE:To control the treatment of activated sludge with high capacity by estimating CODcr.ATP load being one of the expression systems of an F/M ratio in the treatment of activated sludge from the ORP of an aeration tank and estimating of the CODcr of inflow water and that of treated water from the estimated CODcr.ATP load and the ATP concn. measured value of the aeration tank. CONSTITUTION:CODcr.ATP load is estimated by the operation based on the ORP of an aeration tank and, on the basis of this estimated CODcr load, the inflow water to the aeration tank and the ATP concn. and MLSS of the mixed liquid in the aeration tank, predetermined operation is executed and an F/M ratio factor is estimated on the basis of this operation result.</p> |
