To provide a sludge treatment system and apparatus therefor that withdraw only excess sludge at a site steadily and form sludge reduced in moisture and high in drying degree efficiently in a short time from concd. sludge of domestic waste water housed in a container to be discharge therefrom instead of withdrawing at a time sludge having a concentration capable of being further concentrated for volume reduction and transporting the sludge by a tank truck to other place to treat the same.
Since conc. sludge D emitted from a nozzle is placed on a continuous running air and water permeable sheet 5a to be passed through a dehydrator 6 and dryer 7, moisture of sludge D is efficiently dehydrated and filtered by the dehydrater 6 and, since hot air passes through the sludge D on the air and water permeable sheet 5a in the thickness direction of the sludge in the dryer 7, sludge D1 high in drying degree can be formed.
