Description

Technical Field

[0001] This utility model belongs to the technical field of mud separation equipment, specifically relating to a mud separation and treatment system with an integrated pressure filter structure. Background Technology

[0002] Slurry separation and disposal systems are key equipment used in the engineering field to handle high-moisture-content slag and slurry generated in scenarios such as shield tunneling and foundation excavation. Their core function is to effectively separate solid particles and liquid components in slurry through physical separation technology, thereby achieving slag reduction, harmlessness and resource utilization. Such systems have wide application value in fields such as construction waste treatment, river dredging and underground engineering.

[0003] However, existing sludge separation and treatment systems still have some shortcomings in practical applications. Traditional separation and treatment systems mostly adopt open water treatment processes, with the filtrate discharged from the filter press being directly discharged or reused after simple sedimentation. This results in the inability to effectively remove residual fine particulate matter and dissolved pollutants in the water, causing water waste and potentially secondary pollution. Furthermore, the replacement of filter media in the filtrate treatment module is complex. For example, components such as activated carbon filter cartridges are usually fixed with bolts or nested installations, requiring system interruption and disassembly with specialized tools for replacement, which is time-consuming and affects continuous treatment capacity. To address these issues, the applicant proposes a sludge separation and treatment system with an integrated filter press structure. Utility Model Content
