摘 要：為了研究微气泡臭氧氧化技术处理废水的影响因素,采用微气泡臭氧氧化技术处理酸性大红3R废水,考察臭氧投加量、酸性大红3R废水初始浓度和投加活性炭对微气泡臭氧氧化过程中脱色率、TOC去除率、pH值以及臭氧利用率的影响.结果表明,提高臭氧投加量或降低酸性大红3R废水的初始浓度,酸性大红3R废水的脱色速率和TOC去除速率均有所上升,但臭氧利用率下降.煤质活性炭对微气泡臭氧氧化具有较强的催化活性,能够显著提高酸性大红3R废水的脱色速率和TOC去除速率.臭氧投加量为48.3 mg/min、酸性大红3R废水的初始质量浓度为100 mg/L时,处理效果较好.此条件下,处理30 min时脱色率达到100%,处理120 min时TOC去除率达到78.0%,TOC去除表观反应速率常数为0.015 min-1,臭氧利用率始终高于99%.而投加5 g/L煤质活性炭后,处理15 min后脱色率达到100%,处理120 min时TOC去除率可达到912%,TOC去除表观反应速率常数提高至0.037 min-1.处理过程中出现中间产物小分子有机酸的积累并继续氧化降解,使得废水的pH值呈现先下降后升高的趋势.可见,对微气泡臭氧氧化影响因素进行优化,可提高污染物去除速率及臭氧利用率,显著改善处理性能.

Abstract： The microbubble ozonation was used to treat acid red 3R wastewater in order to investigate the influencing factors on its performance. The effects of ozone dose, initial acid red 3R concentration and activated carbon on the performance of microbubble ozonation treatment of acid red 3R wastewater are investigated. The decolorization rate, TOC removal rate, pH variation and ozone utilization efficiency in the microbubble ozonation treatment are compared under different treatment conditions. The results indicate that when increasing ozone dose or decreasing initial acid red 3R concentration, both decolorization rate and TOC removal rate of acid red 3R wastewater increase, but ozone utilization efficiency decreases. The coalbased activated carbon shows strong catalytic activity for microbubble ozonation, which could enhance the decolorization rate and TOC removal rate of acid red 3R wastewater. The better performance of microbubble ozonation treatment is achieved when the ozone dose is 48.3 mg/min and the initial acid red 3R mass concentration is 100 mg/L. Under these conditions, the decolorization efficiency reaches to 100% after treatment for 30 min, the TOC removal efficiency reaches to 78.0% after treatment for 120 min, the reaction rate constant of TOC removal is 0.015 min-1 and the ozone utilization efficiency is higher than 99%. With addition of the coalbased activated carbon of 5 g/L, the decolorization efficiency reaches to 100% after treatment for 15 min, the TOC removal efficiency reaches to 91.2% after treatment for 120 min and the reaction rate constant of TOC removal increases to 0037 min-1.The accumulation and following degradation of intermediate products of all molecule organic acid happens during treatment process, and as a result, the solution pH decreases initially and then increases. Therefore, the optimization of influencing factors for microbubble ozonation could increase both contaminant removal rate and ozone utilization efficiency, and then improve treatment performance significantly.
