Abstract

PURPOSE: To prevent the production of a high SS separated liquid while compacting a treating device by concentrating organic sludge by a heat treatment after mechanical concentration.
CONSTITUTION: After coarse foreign matter is removed from raw sludge from a part A, the raw sludge is thrown into the longitudinal concentrating machine 2 or lateral concentrating machine 3, where it is treated to an about 5W6% solid separation rate and sent to a sludge storage tank 4. This sludge is heated by the 1st heat exchanger 5 and further heated up to a prescribed temperature by a reaction can 7. Separate gas is conducted in a direction B to be treated, and the heat-treated sludge is introduced into the 2nd heat exchanger 6 to be cooled and further cooled sufficiently by a cooler 8. Then, it is carried to a heat-treatment sludge storage tank 10, and a dehydrater 11 performs solid-liquid separation. Consequently, the capacity of the treatment is decreased to compact the devices or the like, and the cost of the heat treatment is reduced while an SS component in a separated liquid is reduced to about 200W300mg/l.
