Research on the treatment of hard degradation organic in fermantative wastewaterby UV/O_3 catalytic oxidation

以UV/O3氧化法降解生化处理后的发酵有机废水为处理体系,研究了活性炭、二氧化钛对废水中难降解有机物的UV/O3催化活性,考察了催化剂用量以及活性炭和二氧化钛的协同催化效果。结果表明,活性炭与二氧化钛均能明显加快反应速率,提高CODcr去除率并缩短反应时间,且活性炭与TiO2协同催化效果更好,二者以最佳比例(6∶1)作用,反应4h后,废水的CODcr去除率达到85%以上。

By UV/O_3 catalytic oxidation to treat fermentative wastewater,a research on the effect of active carbon,titanium dioxide on the catalytic activity of hard degradation organic compounds is carried out.Catalytic consumption and cooperative catalytic effect of active carbon and titanium dioxide are studied.It is found that the active carbon and titanium dioxide can obviously increase the reaction rate and COD_(cr) clean efficiency,decrease reaction time.
