Abstract

Abstract: The method of three-dimensional-electrode was used to study the pretreatment of sorbic acid wastewater. The operational parameters that affected the efficiencies of the wastewater treatment were discussed, including electrode material, applied voltage, pH value, electrolysis time, and so on. The experimental results showed that the removal ratio of COD reached to 48% and the BOD/COD increased to 0.40, when the voltage was 20 V, the working electrodes distance was 11 cm, the electrolysis time was 20-30 min, the pH value of wastewater was 4.0±0.2, under the condition of stainless steel as anode, graphite as cathode and cylindrical activated carbon as particle.

Key words: three-dimensional-electrode, activated carbon padding, sorbic acid wastewater
