紫外/过氧化氢对含氮染料废水的处理

Treatment of nitrogen-based waste dye water with UV/H_2O_2

纺织印染废水的降解主要是针对含氮染料废水的处理,利用UV/H2O2的工艺方法处理含氮活性染料活性黑5号(Reactive B lack 5(RB5))的印染废水,研究染料RB5降解过程中过氧化氢浓度及紫外光强度对染料RB5废水降解程度的影响.结果表明,印染废水的降解分为脱色和分解两步进行.

The degradation of waste dye water is mainly the treatment of nitrogen - based waste dye water. UV/ H2O2can be used to treat waste dye water containing RB5 （ Reactive Black 5, a kind of activated carbon material）. Experiments were made to study the effect of H2O2 density of and UV rays on the RB5 - based dye water, and result demonstrated that the degradation is of two steps, i.e. colorless - treating and disintegration.
