  • 摘要: 针对活性炭催化臭氧化降解低质量浓度含氰废水体系,研究了活性炭吸附、催化作用在催化臭氧化体系中的作用,提出了吸附-催化臭氧化协同作用机理。在活性炭-臭氧体系中,活性炭吸附CN-的能力很弱,活性炭在反应体系中主要起了吸附、催化臭氧的作用。活性炭-臭氧体系降解CN-的过程是臭氧直接氧化、活性炭吸附臭氧与活性炭催化臭氧产生·OH自由基间接氧化三者共同作用的结果。
    Abstract: According to the degradation of low consistency cyanide wastewater with activated carbon catalytic ozonation,effect of the adsorption and catalytic capability of activated carbon in the catalytic ozonation system was investigated. Furthermore, an adsorption-catalytic ozonation synergistic mechanism was proposed. The experimental results indicated that the adsorption capability of CN- by activated carbon was very weak but the adsorption capability of ozone was stronger. The activated carbon mainly played the role of adsorbing and catalyzing ozone in the wastewater treatment system. It was proved that the CN- removal process by activated carbon catalytic ozonation was the homo-result of ozone direct oxidization,activated carbon adsorption and indirect oxidization of hydroxyl radical.
