摘　　要：以空气为载体的微纳米气泡为基础,研究温度、时间、pH值等影响因素对微纳米气泡在水中的溶解氧的影响,并通过正交试验探究微纳米气泡在水中溶解度的优化条件.正交试验结果表明,以空气为载体的微纳米气泡优化条件为pH值7、时间8min、温度23℃、转速1 300r/min时溶解氧含量较高.此实验为下一步研究微纳米气泡在工业废水中的应用提供依据.In this study,base on the air carrier＇s micro-nano bubble the influencing factors of temperature, time,pH,dissolved oxygen and other gas bubbles in the water were invastigated the optimum conditions of miero-nano bubbles in water solubility were obtaired by orthogonal test. Orthogonal test results showed that the air carrier＇s micro-nano bubble optimum conditions include pH 7,time 8 min,tempera- ture 23 ℃ tspeed 1 300 r/min, under this conditions the dissolved oxygen content is higher.This experi- mental study of micro-nano bubble for the next application in industrial wastewater treatment provids evidence.
