摘要
本文以铬黑T染料代替印染废水,通过实验研究活性炭在不同条件下对其吸附的效果。了解吸附时间,染料浓度,染料ph值,吸附温度等因素对活性炭吸附效果的影响,找出这些因素对活性炭吸附的影响规律。得到吸附时间,染料浓度,染料ph值,吸附温度等因素的最佳吸附值。根据这些因素的影响规律设计正交实验。通过正交实验找出吸附时间,染料浓度,染料ph值,吸附温度等活性炭最优的吸附条件的组合。并根据这些因素的影响规律对活性炭吸附法处理铬黑T染料废水的吸附脱色机理进行了探讨,为以后提高活性炭的利用率,节约能源,提供理论与实验基础。

Abstract
In this paper, with chrome black T dye instead of printing and dyeing wastewater, through the experimental study of active carbon in different conditions on the adsorption effect, understanding of adsorption time, dye concentration, dye pH, factors affecting the adsorption temperature on the adsorption effect, to find the influence factors of activated carbon adsorption, adsorption time, dye the dye concentration, pH value, the optimal adsorption factors of adsorption temperature value. According to the influence of these factors by orthogonal experimental design, find out the adsorption time, through orthogonal experiments, dye concentration, dye pH, combination as well as the adsorption temperature, activated carbon adsorption conditions of the optimal. According to the influence of these factors on the activated carbon adsorption treatment of chrome black T dye wastewater decolorization mechanism was discussed, saving energy to improve the utilization of activated carbon,, to provide theoretical and experimental basis.
Key words: Activated carbon, adsorbent, Chrome black T dye, the adsorption rate
