Removal of Congo Red from Dyeing Wastewater by Biodegradation with Myriophyllum

Abstract:

Article Preview

In this study, Myriophyllum was used to remove Congo Red dye from wastewater. The influence of operation factors include illumination intensity, initial pH, biomass and dye concentration on the degradation rate of Congo Red were investigated. The experimental results demonstrated that Myriophyllum can effectively degradate Congo red dye. The Congo red dye was almost completely discolored in 10 days under the conditions of 5000 lx of illumination density, 7.5 of pH, 15g /L~17.5 g/L of initial biomass and less than 20 mg/L of Congo red concentration. Furthermore, the great reduction of intermediate products and COD indicated that biodegradation of Congo red dye with Myriophyllum not only produced less secondary pollution, but also mineralized azo dye into inorganic matters. Myriophyllum in pollutants degradation presented obvious technical advantages and environmental benefits.
