摘　　要：选取微废在线循环使用切削液作为研究对象,采用电絮凝/臭氧杀菌工艺作为切削液修复的处理方法,研究了直流条件下电极间距、电流密度、通电时间、倒极时间等因素对SS去除率、COD的影响.确定了最优的试验条件:电流密度为15 mA/cm_2、极板间距为10 mm、通电时间为20 min、倒极周期为15 s时,切削液的SS去除率可92.12%.臭氧曝气时间为10 min,杀菌率达到99.96%.经过电絮凝/臭氧杀菌工艺修复和添加新切削液后,其消泡性、防锈性、防腐性等指标得到明显改善,可以继续进行在线循环使用.本研究为工业大批处理机械加工切削液的新方法及新工艺提供了技术参数依据.The quasi scrip recycling online used cutting fluid is selected as the research object,and the process of electric flocculation and ozone sterilization is used as pretreatment method of restoring cutting fluid,which examines the influence of the electrode spacing,current density,electric time and time of replacing the electrode on the removal rate of suspended solids,chemical oxygen demand and under conditions of direct current.The optimal experiment conditions are determined as the current density of15mA/cm2,electrode distance of10mm,electric time of20min and pole switching time of15s.The removal efficiency of suspension solids of the cutting fluid reachs up to92.12%.When ozone aeration time is10min,the bactericidal rate can be as high as99.96%.After purification regeneration for cutting fluid by the process of electric flocculation and ozone sterilization and adding new cutting fluid,its antifoaming performance,anticorrosive performance,antirust and other performances are improved obviously,and it can continue to be used online circulation.
