SLUDGE DEHYDRATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a sludge dehydrating apparatus which has simple structure requiring no special container and can efficiently dehydrate liquid-mixed sludge.

SOLUTION: A liquid tank 25 receiving liquid 24 dropping through a mesh-like partitioning plate 21 is provided under a sludge tank 23 receiving dropping liquid-mixed sludge 22 by the mesh-like partitioning plate 21. A draining pipe 26 draining the liquid 24 is connected to a lower part of the liquid tank 25. One end of an air intake pipe 29 is opened to a space 28 above an upper limit of the set level of the liquid 24 in the liquid tank 25 kept by draining the liquid 24 by the drain pipe 26 and below a filter medium 21, and a vacuum pump 31 is connected to the other end of the air intake pipe 29.
