摘　　要：采用微波辐射对切削液废水进行预处理,在不同微波功率下(150,300,450,600,700,900 W)使切削液废水达到不同温度范围(40~50,50~60,60~70,70~80,80~90,90~100℃).将辐射后废水分为上、中、下3层(上层160 mL、中层300 mL、下层100 mL),并检测各层废水的COD和粒径,以探究能耗、有机物挥发量,并确定最佳破乳参数(微波功率、辐射后废水温度).实验结果表明:各功率下,微波辐射后温度在70~80℃范围内时,破乳效果最佳;微波功率为600 W时,有机物挥发量和能量损耗最小,故微波功率600 W,预处理温度为70~80℃之间,为微波预处理切削液废水的最佳操作条件.The cutting fluid wastewater was pretreated by microwave radiation under different microwave power(150,300,450,600,700,900 W)in the different temperature ranges(40-50,50-60,60-70,70-80,80-90,90-100℃).The radiated wastewater was divided into upper,middle,and lower layers(upper layer:160mL,middle layer:300 mL,and lower layer:100 mL),and the COD and the droplet size of each layer of wastewater were detected to explore the energy consumption and quantity of the organic volatilization,and to determine the best demulsification parameters(microwave power and temperature of the radiated wastewater).The experimental results show that under different microwave power,the demulsification effect is the best when the radiated wastewater temperature is in the range of 70-80℃;when the microwave power is 600 W,the quantity of organic volatilization and lost energy are the least;therefore,the microwave power is 600 W and the radiated wastewater temperature is between 70-80℃,which are the best operating condition for microwave pretreatment of cutting fluid wastewater.
