[0002] Harmless treatment, an academic term in environmental science, means: making garbage no longer pollute the environment and can be used, turning waste into treasure, removing moisture from flowing primary, concentrated or digested sludge, and converting it into semi-solid or solid mud blocks. A sludge treatment method. After dehydration, the sludge moisture content can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dehydration equipment. Further dehydration of sludge is called sludge drying. The moisture content of dried sludge is less than 10%.
