摘要
This paper contributes to the Industrial Ecology Concept by using a common urban solid waste, i.e., coffee residues, to clean industrial wastewaters polluted by basic dyes, e.g., Methylene Blue. For the data from the continuous fixed-bed column system, two common models, namely （a） Bohart and Adams and （b） Clark were implemented. The Bohart and Adams capacity was up to N = 46,166 mg.L-1 or q0 = 104.5 mg.g-1 for bed-depth 15 cm, initial dye concentration 800 mg.g-1 and flow rate 20 mL.min-1. The results revealed that the Methylene Blue is fairly adsorbed on coffee residues. Consequently, this process can be applied as a low cost technique for cleaning basic dyes from the aquatic environment.
