Abstract

PURPOSE: To obtain dehydrated sludge cake having a low moisture content and lesser ash content even after incineration by the procedure in which hydrogen peroxide and activated carbon are added to concentrated sludge, stirred, and then dehydrated.
CONSTITUTION: Sewage supplied to the sewage treatment apparatus 1 is treated to the sludge 3 containing approx. 1% solids and then sent to the concentration tank 4. And the sludge 3 is further concentrated in the tank 4 and then separated into the concentrated sludge 5 containing approx. 4% solids and the supernatant 6. Then, the sludge 5 is sent into the hydrogen peroxide mixing tank 10 and sufficiently stirred 15 with an appropriate amount of the hydrogen peroxide 12 from the storage tank 11. Then, the hydrogen peroxide-containing sludge 16 is supplied to the activated carbon mixing tank 19 and stirred sufficiently, whereupon nascent oxygen is generated from the hydrogen peroxide 12 to decompose and solubilize organic colloids, etc., present among the solids of the sludge 16. And, the solubilized and concentrated sludge 24 is dehydrated by the dehydrator 27, the dehydrated sludge cake 30 is taken out 31, and the separated liquid 28 is discharged to the outside.
