外文摘要：This paper analyzed the effects of granular activated carbon mesh size, absorption temperature and time, dye wastewater pH value and concentration, and structure of disperse dye on the decolorization rate of activated carbon in dye wastewater, which can be used to investigate the adsorption effect of granular activated carbon for the dye wastewater. The research results show that the decolorization rate of cocoanut activated carbon used to adsorb disperse dye increases at a quadratic function with the increase of the granular activated carbon mesh size and absorption temperature, and it also increases exponentially with the extension of absorption time. However, the decolorization rate of cocoanut activated carbon used to adsorb disperse dye decreases at a quadratic function with the increase of dye wastewater pH value, and it also decreases exponentially with the increase of dye wastewater concentration. Furthermore, the decolorization rate of cocoanut activated carbon is lower when the number of polar groups of disperse dye is larger.
