Abstract

Copper and fluoride ions were removed from wastewater by the coupling of electrocoagulation, fluidized bed and micro-electrolysis (EC/FB/ME) process. The results indicate that the use of aluminum electrode for simultaneous removal of copper and fluoride ions is better than iron electrode. By the orthogonal experiments study of the main factors influencing the efficiency of the treatment process, the best control parameters of this process were achieved in four aluminum electrodes, an initial pH of 5.0, a hydraulic retention time of 30 minutes, an applied voltage of 5V, a mass of iron-carbon (Fe/C) of 45g and the particle diameter of Fe/C of 20-27 mesh. With these conditions and the initial concentration of ions of 50mg/L, the residual concentration of copper and fluoride are 0.205 mg/L and 2.936 mg/L, respectively. The EC/FB/ME process is suitable for treatment of wastewater that fluoride concentration is less than 50 mg/L and copper concentration is less than 200 mg/L. This process was successfully applied to the treatment of a smelting wastewater sample.
