Document Type and Number:
WIPO Patent Application WO/2021/070545
Kind Code:
A1
Abstract:
Provided are: a monitoring system and a monitoring method that allow accurate monitoring of sludge release properties of a belt press dehydrator; and a control device for the belt press dehydrator that can appropriately control the belt press dehydrator on the basis of the results of this monitoring. This monitoring device for a belt press dehydration system includes a measurement means for an index value corresponding to the state of solids in filter cloth belt washing wastewater of a belt press dehydrator 10, wherein the measurement means includes an irradiation unit that irradiates the filter cloth belt washing wastewater with laser light and a light receiving unit that receives scattered light, and the measurement means determines the index value on the basis of change over time in a scattered light intensity signal.
