【摘要】 文章研究了自制的絮凝剂DFT对酸性大红GR水溶液的脱色作用。考察了单独使用絮凝剂DFT处理酸性大红GR模拟废水时的DFT投加量、pH和絮凝时间等对脱色效果的影响,以及DFT与硫酸铝配合使用时的投加顺序、投加配比和酸度等的影响,并与Y0试剂的脱色性能进行了比较,结果表明,絮凝剂DFT的脱色效果明显优于Y0试剂。更多还原

【Abstract】 In the paper, decolorization of acid brilliant red GR solution tread by flocculant DFT was studied. When the simulating wastewater of acid brilliant red GR was treated only by flocculant DFT, the influences of the dosage of DFT, pH and flocculant time were studied. And the influences of adding procedure, ratio and acidity were examined when treated by DFT with Al2(SO4)3. Compared to the reagent Y0, the decolorizing performance of DFT was much better.更多还原
