摘要
采用气相色谱-质谱联用仪GC-MS对焦化废水中的一股污染源——苯加工废水进行了有机成分分析,并采用紫外光催化纳米TiO2颗粒、臭氧氧化、超声波法以及它们之间的联合技术对焦化苯加工废水进行处理研究,得出了单独使用这些技术时苯加工废水的COD去除规律,并对采用这些技术以及它们之间的联合作用对COD的去除效果进行了比较.
The organic component in the wastewater from benzene extraction process of coke plant was analyzed by GC-MS apparatus. The different treating methods like ultraviolet nano-catalytic TiO2 particles,ozone oxidation,ultrasound operation and the combined technique were adopted to treat the wastewater. The regularity of COD removal was obtained and the effects of those methods and their united techniques were compared.
