为探索高效节能的以苯系物为主的工业异味气体处理工艺,在前期实验基础上,确定了针对苯系物有机废气的Fenton 氧化-光降解-碱洗组合工艺,并建设了废气处理示范工程。结果表明,在进气口甲苯浓度为163.50 mg/ m3情况下,示范工程排气口甲苯浓度为37.30 mg/ m3,对车间废气中甲苯去除率达77.19%,满足大气污染物综合排放标准(GB16297-1996)对苯系物最高允许排放浓度为60 mg/ m3的要求,具有一定推广意义。%In order to explore a high efficiency & energy saving process for industrial benzenes odor gas treatment, the combined process of Fenton oxidation - photodegradation - alkali washing was determined which based on the pre experiments, and the demonstration project was constructed. The result showed that the project’s removal rate for toluene can reach 77. 19% , and the exhaust outlet toluene concentration was 37. 30 mg / m3 in the cases of inlet toluene concentration of 163. 50 mg / m3 , which accorded with the requirement o fmaximum benzene allowable emission concentration standard (60 mg / m3 ) of air pollutants (GB16297-1996).
