摘要/Abstract

摘要：

作为酚类化合物的典型，苯酚在含酚废水中含量高、毒性范围大，掌握水中苯酚的有效处理方法将为含酚废水的高效处理提供技术支撑。本文通过分析5种臭氧催化剂的催化性能，选择A型催化剂作为臭氧射流曝气系统的优选催化剂。优化了系统关键运行参数，结果表明，当循环水流速、废水pH和污染物初始浓度分别为1400L/h、8和148mg/L时，基于A型催化剂的射流曝气系统对污染物具有良好的去除效果，此时废水COD平均去除率为56.7%。以不同时间节点废水的三维荧光光谱、GC-MS和好氧呼吸抑制率作为评价指标，考察了苯酚的阶段氧化进程。综合分析各评价指标，发现当反应时间为60min时，废水三维荧光光谱对应的荧光区域E_x/E_m为(300~350nm)/(420~460nm)可能是苯酚在臭氧高级氧化过程高效率降解、低好氧呼吸抑制的指示因子。

Abstract:

As a typical phenolic compound, phenol showed the characteristics of high content and wide range of toxicity in phenol-containing wastewater. Mastering effective method of phenol treatment will provide technical support for the efficient treatment of phenol-containing wastewater. By analyzing the catalytic performance of five ozone catalysts, type A catalyst was selected as the preferred catalyst in ozone jet aeration system. The key operating parameters of the system were optimized. The results showed that the jet aeration system based on type A catalyst presented the good pollutants removal performance with an average COD removal efficiency of 56.7% when the circulating water velocity, wastewater pH and initial concentration of pollutant were 1400L/h, 8 and 148mg/L, respectively. The stage oxidation of phenol at different time nodes was investigated using three-dimensional fluorescence spectra, GC-MS and aerobic respiratory inhibition rate as evaluation indexes. By comprehensive analysis of the evaluation indexes, it was found that E_x/E_m was (300~350nm)/(420~460nm) region in the three-dimensional fluorescence spectrum might be an indicator of high removal efficiency and low aerobic respiratory inhibition at the reaction time of 60min.
