摘　　要：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。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.
