Abstract

The present invention relates to a sludge dewatering system for continuously dewatering sludge mixed in wastewater produced in factory. More particularly, the invention comprises: upper and lower side compressive belts having caterpillar shape and made by compressing wool, hair or fur into flat; inner side compressive belts each installed inside of the upper and lower side compressive belts, and each having dewatering guides attached to caterpillar type chains, with said dewatering guides 2c being of porous pipe shape; and a pressurizing apparatus comprising pressurizing plates and oil pressure cylinders, wherein said system enables water of sludge contained in wastewater to be dewatered effectively.
