Description

technical field [0001] The invention relates to the field of waterless treatment, in particular to a sludge dewatering machine. Background technique [0002] In industrial production in the field of fermentation, sewage treatment is one of the main environmental problems. Under normal circumstances, through industrial wastewater treatment stations, but the wastewater treatment stations will produce sludge, and the sludge produced generally contains a lot of inorganic sludge, which contains chemical components in the production wastewater, which belongs to the category of hazardous waste and still needs further treatment. . The most basic treatment of industrial sludge is dehydration. [0003] It is known that there are many methods for sludge treatment. The existing sludge dewatering machines mainly include the following: [0004] 1. Plate-and-frame sludge dewatering machine: In a closed state, the sludge driven by the high-pressure pump is squeezed by the plate and frame...
