摘要

将新型套管式微反应器应用于苯酚溶液的臭氧氧化处理体系，考察了套管式微反应器微孔孔径、内外管环隙、苯酚溶液初始质量浓度、温度、pH值和气液比等因素对苯酚去除率的影响。结果表明，苯酚去除率随着套管微孔孔径、内外管环隙和苯酚溶液初始质量浓度的增大而减小；随着气液比和温度的增大而增大；而随着溶液pH值的增大，苯酚去除率则先增大后减小。初始质量浓度为100 mg/L的苯酚溶液在pH为11，气液比为13，套管内管孔径为10 μm，内外管环隙为250 μm,温度为25 ℃的条件下，苯酚去除率可达99%以上。

Abstract

The degradation of phenol in aqueous solution by ozone oxidation has been studied in a microporous tube-in-tube microchannel reactor (MTMCR). The results indicated that the removal percentage of phenol decreased with increasing micropore size, annular channel width and initial phenol concentration, and increased with increasing ratio of gas volumetric flow rate to liquid volumetric flow rate and reaction temperature. It was also observed that the removal percentage of phenol initially increased, and subsequently decreased with increasing pH value. A phenol removal percentage of over 99% was achieved under the following reaction conditions: initial phenol concentration of 100mg/L, micropore size of 10μm, annular channel width of 250μm, ratio of gas volumetric flow rate to liquid volumetric flow rate of 13, pH value of 11 and reaction temperature of 25℃.
