Sludge treatment facility

摘要

Provided is sludge treatment facility that can spray contaminated water evenly in water-containing sludge that has been deposited in a sludge hopper. This sludge treatment facility (1) is provided with a contaminated water recovery mechanism (4) which comprises: a contaminated water recovery tank (3) for recovering contaminated water (6) resulting from cleaning either a sludge hopper (2) that stores water-containing sludge (5) transported from a sewage treatment plant by truck (8) or pipes in the sludge treatment facility (1); and a contaminated water return pipe (7) that transports the water from the contaminated water recovery tank (3) to the sludge hopper (2). The water-containing sludge (5) that is stored in the sludge hopper (2) is treated by a cement manufacturing process (13). A water spraying unit (7a) on the sludge hopper (2) side of the contaminated water return pipe (7) is disposed above the dropping position for the water-containing sludge (5) into the sludge hopper (2) from the truck (8) such that the contaminated water (6) is sprayed onto the peak (5a) of the water-containing sludge (5) that has collected within the sludge hopper (2).
