[0002] As we all know, urban domestic sludge and sludge from industrial wastewater treatment are the inevitable products of sewage treatment plants. At present, most of these sludges are transported to landfills for disposal without deep treatment. The disposal method is simple. The sludge has a high water content and contains rich nitrogen and phosphorus nutrients as well as heavy metals, difficult-to-degrade organic matter, salts, pathogenic bacteria, parasites and other harmful components. Improper treatment or disposal will cause secondary pollution problems, seriously threatening people's health and the ecological environment.

Some can only dehydrate sludge with a moisture content of 80% to about 45%, and the removal of water requires recycling energy, which increases energy consumption. Some can only dehydrate sludge from 99% to about 55%, which does not meet the new standard of moisture content below 50% set by the environmental protection department and related comprehensive utilization moisture content standards. In order to achieve a high level of deep dehydration of sludge, the properties of sludge that affect the dehydration effect must be adjusted.
