Abstract
The experiment uses three ozone photocatalytic oxidation processes to treat diazodinitrophenol(DDNP)wastewater,namely ultraviolet(UV)/O3,UV/O3/H2O2,UV/O3/Fe(Ⅲ).The results show that in the UV/O3/H2O2 process,with the addition of H2O2,when the ratio of H2O2 to nitrophenol compounds is 3∶1,the oxidation reaction lasts for 1 h,and the effluent color and total organic carbon(TOC)meet the relevant emission standards;in the UV/O3/Fe(Ⅲ)process,with the addition of Fe(Ⅲ),when the ratio of Fe(Ⅲ)to nitrophenol compounds is 0.1∶1.0,the oxidation reaction lasts for 1 h,and the effluent color,TOC,and nitrophenol compounds all meet the relevant emission standards,and the process treatment efficiency is as high as 58%.关键词
