Abstract

PURPOSE: To prevent the use of municipal water and industrial water for washing water as far as possible in a dehydrator using a belt press type dehydrating machine by washing filter cloth belts with the filtrate obtd. in the gravity dehydration part of the dehydrating machine and utilizing the waste water of said washing for uniform supplying of sludge.
CONSTITUTION: Sludge is mixed with a cationic high polymer flocculating agent then with an anionic one and the mixture is supplied onto a gravity dehydration part A with a sludge supplying device 7. Since the solids in the sludge have been grown to large flocs, a large amt. of water is filtered out into a receiving box 6. This is stored in a storage tank 15, and is fed to nozzles 3, 8 so that it is used for washing of main and auxiliary belts 1, 2. In the initial period of operation, there is no filtrate in the tank 15 and therefore municipal water or the like is put therein and is used. The waste water of the washing after washing the belts is gathered in a receiver 11 for the filtrate to be filtered out by the pressurizing part B of the dehydrating machine and this water is supplied together with the filtrate to the device 7 or a conduit 14 which conducts the sludge to this. In this way, the sludge is diluted and lends itself to the supply of the sludge by the device 7 to the entire width of the belt 1 at uniform thickness.
