多相催化臭氧氧化法处理甲萘酚废水

以活性炭为载体、钾为助催化剂,采用浸渍法制备了Cu-K/AC催化剂,并考察了该催化剂催化臭氧氧化处理甲萘酚废水的效能.结果表明,当甲萘酚废水的COD为3 000 mg/L、含油量为120 mg/L时,在室温、pH=3、反应时间为120 min、催化剂投量为100 g/L、臭氧流量为5.2mg/min的条件下,催化臭氧氧化对COD及油类物质的去除率分别达到了93%和98%;臭氧氧化和催化臭氧氧化对COD的降解过程均符合表观一级反应动力学方程.

Heterogeneous Catalytic Ozonation Process for Treatment of Wastewater from 1-naphthol Production

Taking activated carbon as carrier and potassium as cocatalyst, the Cu-K/AC catalyst was prepared by impregnating process. The efficiency of this catalyst for treating wastewater from 1-naph-thol production was investigated in catalytic ozonation process. The results show that the removal rates of COD and oil can reach 93% and 98% under the conditions of COD of 3 000 mg/L, initial oil concentra-tion of 120 mg/L, ambient temperature, pH of 3, reaction time of 120 min, catalyst dosage of 100 g/L and ozone of 5.2 mg/min. The degradation of COD by ozonation and catalytic ozonation conforms to the first-order reaction kinetics equation.
