摘　　要：针对切削废液的处理成本高、难度大的问题,从切削废液再生、回用的角度出发,研究采用UV+O_2高级氧化法对铝合金切削废液进行处理,并从细菌含量、润滑性、pH、防腐性等方面来对比处理后的切削废液与新鲜切削液。结果表明,UV协同O_2高级氧化法处理铝合金切削废液,能够快速有效的杀死切削废液中的细菌,处理3 h后,杀菌率达到99.27%;同时能够改善切削废液的润滑性能,提高pH,处理3 h后的pH为9.74,略低于新鲜切削液;处理后的切削液中,铝合金的自腐蚀电位明显正移,切削液的防锈性能显著提高。处理后的切削液各项性能基本得到恢复,并且达到回用的效果,是一种绿色环保高效的处理切削废液的方法。The cutting liquid waste has high treatment cost,and is difficult to treat.In order to regenerate and reuse the cutting liquid waste,the advanced oxidation method was used to treat aluminum alloy cutting liquid waste.The bacteria content,lubricity,pH and rust-preventing characteristics of treated cutting liquid waste were compared with those of fresh cutting fluid.The results indicated that UV/O2advanced oxidation process could quickly and effectively kill the bacteria in the cutting liquid waste,and the bactericidal rate reached99.27%after treated for3h.Meanwhile,the lubrication performance of cutting liquid waste was greatly improved and the pH increased to9.74slightly lower than fresh cutting fluid after3h treatment.The corrosion potential of aluminum shifted positively and the antirust property of cutting fluid was improved.After treatment by UV/O2advanced oxidation process,the properties of cutting liquid waste were recovered and closed to those of fresh cutting fluid and the cutting liquid waste could be reused.It is a green and efficient way to treat liquid fluid waste.
