| dc.description.abstract | This study was performed to investigate the removal ability of dyeing wastewater containing C.I. Acid Red 114 by ozonation and electrocoagulation in batch mode. In ozonation, the effects of some parameters: ozone gas flowrate, pH, temperature and initial dye concentration on color, dye and COD removal efficiencies were evaluated. And the gas holdup by ozone gas, volumetric mass transfer coefficient of ozone, enhancement factor and energy consumption were determined. In electrocoagulation, the effects of current density, initial dye concentration, pH and conductivity on color, dye and COD removal efficiencies were determined. Energy consumption and sludge production were evaluated. The results showed that the removal efficiencies of color and dye were higher than 95% with 50 min ozonation and 90% with 20 min electrocoagulation. The COD removal efficiencies were 79% and 89.3% in ozonation and electrocoagulation, respectively. In ozonation, the removal efficiency was affected by the ozone gas flow rate, pH, temperature and initial dye concentration. And in electrocoagulation, the treatment performance was significantly affected by current density and initial dye concentration. Ozonation consumed more energy than electrocoagulation, but it produces no sludge. Both methods are feasible for application in the treatment of dyeing wastewater containing C.I. Acid Red 114. | |
