CNC机加工切削液净化再生与失效液处理

      CNC机加工切削液中的污染物主要为：金属切屑颗粒、油污杂质、乳化油、微生物菌群、磨削泥、金属离子、添加剂降解物及悬浮胶体杂质，为固液复合类污染。

切削液净化再生可高效去除各类污染物，恢复使用性能，核心优点：大幅降低新液采购成本，减少废液排放量；循环复用保障加工润滑冷却效果，提升加工精度与刀具寿命；减少危废产生量与清运处置费用，节约生产能耗与物料损耗。对不可再生的失效切削液，采用减量化+无害化+无废化工艺处理，可浓缩减量降低危废体量与处置成本，深度降解污染物杜绝环境风险；同步实现基础油、导轨油资源化回收提纯回用，固液废全量合规处置，全程契合环保法规，兼具降本与绿色生产双重效益。

Brief Introduction to Purification and Regeneration of CNC Machining Cutting Fluid and Treatment of Spent Fluid

       The main pollutants in CNC machining cutting fluid include metal chip particles, oil impurities, emulsified oil, microbial flora, grinding sludge, metal ions (Fe, Al, Cu, etc.), additive degradation products and suspended colloidal impurities, belonging to solid-liquid composite pollution.

Purification and regeneration of cutting fluid can efficiently remove various pollutants and restore service performance, with core advantages: significantly reduce the procurement cost of new fluid and waste fluid discharge; cyclic reuse ensures machining lubrication and cooling effect, and improves machining accuracy and tool life; reduce hazardous waste generation, transportation and disposal costs, and save production energy and material consumption.

       For non-regenerable spent cutting fluid, reduction-harmlessness-zero waste treatment is adopted, which can realize concentration reduction to cut hazardous waste volume and disposal cost, and deep degradation of pollutants to eliminate environmental risks. Meanwhile, it realizes resource recovery, purification and reuse of base oil and guide rail oil, as well as compliant disposal of all solid and liquid waste, fully complying with environmental regulations and achieving dual benefits of cost reduction and green production.
