近紫外光-AgCl体系脱色处理活性艳红K-2BP染料废水

 以近紫外光为光源，AgCl为催化剂，考查了染料初始浓度、催化剂用量、pH值、不同光源等因素对活性艳红K-2BP染料废水脱色的影响。结果表明，当染料初始浓度为50mg/L，催化剂浓度为1000mg/L，pH值为4.0时，活性艳红K-2BP模拟染料废水脱色率达到72.1％。在该工艺条件下，用于实际染料废水，脱色效果也很明显。在此基础上，建立了活性艳红K-2BP降解的动力学方程，分析了活性艳红K-2BP降解机制，确定了K-2BP降解过程中一些被取代的芳香化合物的结构组成以及反应的中间产物和最终产物，并由此推测出其降解路线。

Treatment for Decoloring Reactive Brilliant Red K-2BP Dye Wastewater By Near UV-AgCl

The dye wasterwater has some unique features:high CODCr,high intensity of color,high salinity,hard to degradation,great changes in water quality and quantity and so on.It becomes oxidation resistant and anti-bio-degradable,which makes it difficult to be treated.The general aim of treatment is to remove COD and to decolor,which is more difficult.Color is the most important indicator to check whether the printing and dyeing wastewater treatment can meet the emission standards.With the traditional method of wa...
