SLUDGE DEHYDRATION SYSTEM

摘要

The present invention relates to a sludge dewatering system; a sludge dewatering system (10) includes a concentration apparatus (12) that concentrates sludge while conveying the sludge on a top surface (16a) of a filter cloth belt (16) and a dewatering apparatus (14) that subjects the sludge discharged from the concentration apparatus (12) to pressure dewatering; and the concentration apparatus (12) includes a filtering unit (18) that subjects the sludge added with a first chemical agent to gravity filtration, a second chemical feeder (36) that adds a second chemical agent to the sludge conveyed in the filtering unit (18), and a moving mechanism (30) that moves the sludge added with the second chemical agent to a direction intersecting a conveyance direction of the filter cloth belt (16).
