光、电催化氧化降解染料废水的研究

Study on the Degradation of Dye Wastewater by Photo-Electric-Catalyzed Oxidization

在光催化剂的参与下,光催化产生·OH、·O2-等自由基,电催化产生·OH、OH-等自由基,这些自由基是水系中存在的氧化能力最强的氧化剂。本实验将光、电协同催化应用于直接深兰L废水的处理上,研究了影响染料废水脱色(降解)的有关因素。表明了在电场作用下,光催化氧化的效果将得到加强,从而大大提高了染料废水的降解速率。

By the action of photocatalyzer, it produced free radicals, such as ·OH、·O2^-with photocatalysis and ·OH, OH^- with electrical catalysis, which oxidizability is the strongest in the water system. This experiment applied photo - electric - catalyzed to treat substantive mazarine （L） wastewater. It researched the relative factors which affected the decolorized degradation of dye wastewater. It showed that with the role of the electric field it improved the effect of photo - catalyzed oxidization, so it immensely enhanced the degradation rate of dye wastewater.
