Sludge treatment equipment, sludge treatment system and sludge treatment method

摘要

PROBLEM TO BE SOLVED: To provide a sludge treatment apparatus, a sludge treatment system and a sludge treatment method capable of stably reducing the water content of dehydrated sludge and saving energy in sludge treatment. SOLUTION: In order to solve the above problems, a sludge treatment device including a mixing unit for producing a mixture of sludge and wood chips and a crushing unit for crushing the mixture produced in the mixing unit, and the sludge treatment device. A sludge treatment system including the above, and a sludge treatment method by this sludge treatment device are provided. According to the present invention, by first mixing sludge and wood chips and crushing them in a wet state, it is possible to suppress the generation of dust and suppress the decrease in the mixing efficiency of sludge and wood chips. As a result, when the finely divided wood chips are dispersed in the sludge, the energy saving of the device can be achieved. In addition, the wood chips can effectively function as a dehydrating agent or a dehydration aid, and the water content of the dehydrated sludge can be stably reduced. [Selection diagram] Fig. 1
