二氧化硫脲对高色度活性染料废水预处理的应用探讨

摘要

This article discusses the pretreatment of high color reactive dye wastewater with thiourea dioxide. The experimental results show that under the conditions of alkalescence, room temperature, less than 0. 1％ thiourea dioxide dosage and more than 2 h process time, the thiourea dioxide has a good decolorization effect on the high color wastewater of some commonly reactive dyes. It can be used as a reagent for pretreating decolorization of high color active wastewater.%本文探讨了二氧化硫脲预处理高色度活性染料废水,实验表明:微碱性、室温、低于0.1％药剂量、维持2 h以上条件下,二氧化硫脲对一些常用活性染料的高色度废水均有良好的脱色效果,可以作为高色度活性染料废水预处理脱色的药剂.
