Abstract

PURPOSE: To raise the efficiency of post tretment of sludge by treating excessive sludge alone obtained in a separation tank in the outside of treatment system in a water treatment method in which treated water from an oxidation treatment tank is further treated in a separation tank, a retreatment tank, and a sedimentation tank.
CONSTITUTION: Treated water from the oxidation treatment tank 1 is supplied to the separation tank 2 to recover the floating sludge, and then part of the floating sludge is returned through the first return path R1 to the oxidation treatment tank 2 and also its excessive sludge is tanke out to the outside and then introduced into the post treatment apparatus 3, where dehydration and incineration are conducted. On the other hand, the treated water from the separation tank 2 is supplied to the denitrification tank 4 to reduce nitrogenous components by activated sludge and then sent to the sedimentation tank 5 to sediment and remove sludge from the treated water, where the separated sludge is all recovered and returned to the oxidation treatment tank 1. Also, the excessive enriched sludge alone recovered from the separation tank 2 is discharged to the outside and then treated.
