This invention provides a multi-stage
environmentally friendly water-based
cutting fluid regeneration process, belonging to the field of
industrial wastewater treatment and recycling technology. This multi-stage
environmentally friendly water-based
cutting fluid regeneration process includes S1, a gravity
sedimentation coarse
filtration stage: waste
cutting fluid is subjected to long-term gravity
sedimentation under specific hydrostatic conditions, specifically for removing heavy, large-particle impurities, providing pretreatment for subsequent precision
filtration. By setting up multi-stage progressive and functionally specialized physical purification stages, the process systematically solves the problem of efficiently removing complex pollutants from waste
cutting fluid. Compared to traditional single-treatment methods, this process first utilizes gravity
sedimentation to specifically target heavy, large particles, then uses a specific mesh filter to selectively trap lightweight abrasives, subsequently uses
centrifugal force to efficiently separate fine
metal powders, and finally uses a
nanofiber membrane to achieve deep removal of submicron-level impurities and colloids.
