Abstract

PURPOSE: To reduce load on installation as well as enable treatment to be performed even if the properties of sludge vary by the procedure in which the purification tank sludge is put directly in a dehydrator for dehydration without passage through storage tank, and then the filtrate is charged into an aeration tank.
CONSTITUTION: Raw night soil A is as usual charged into the digestion tank 3 through the residue remover 1 and the storage tank 2 and afterwards treated likewise. But, the purification sludge B is charged directly in the dehydrator 11 without passage through the digestion tank 3, and then the filtrate f is put into the dilution water tank 5 to dilute it with the dilution water a to a proper concentration, as usual, and then sent to the aeration tank 6. Then, dehydrated cake obtained after dehydration is, as usual, incinerated or thrown away.
