Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment equipment, and in particular to a filter press equipment for multi-source sludge. Background Art

[0002] Typical domestic industries such as chemical industry, electroplating, pickling, printing and dyeing will produce a large amount of sludge during the wastewater treatment process. According to the requirements of the technical specifications for hazardous waste identification, these sludges need to be sampled separately from the sludge produced in different process links during the identification of hazardous characteristics according to the environmental governance and pollution control process flow.

[0003] However, in the actual operation of enterprises, the sludge generated in the wastewater treatment process is often filtered together, which makes sampling difficult; at the same time, the existing filter press equipment for sludge treatment has low filter press efficiency, and the mud cake after filtration still contains a large amount of water, which is not conducive to the subsequent treatment of the sludge and increases the sludge treatment cycle; moreover, the sludge is very easy to clog the filter holes of the filter cartridge under pressure, which makes manual cleaning difficult and affects the working efficiency of the equipment.
