摘要
实验首次将一种新型光源—无极紫外灯应用于染料废水的降解,考察反应过程中染料脱色率,TOC去除率,pH值的变化情况,并与普通紫外光的降解情况进行了比较。实验表明,染料活性艳蓝KN-R溶液经过无极紫外光处理110min后,脱色率达73%,TOC去除率达34%,而普通紫外光对染料的脱色率只有8%,TOC基本上没有变化。
A new lamp source, electrodeless ultraviolet lamp is proposed firstly to treat dyeing wastewater reactive brilliant blue KN-R. Three variations, the dye decolorization efficency, total organic carbon (TOC) removal ratio and pH level during the reaction time were investigated.The comparison between the degradation by electrodeless ultraviolet and common ultraviolet was also carried out. Experimental results showed when treating time was110 minutes, the decolorization efficency and TOC removal ratio of dye reactive brilliant red X-3B were 73% and 34%, respectively. However, the decolorization efficency by electrode ultraviolet lamp was only 8%, and TOC was invaried basically.
