Study on Treatment of Waste Emulsion with Pulse-Electrolysis

Abstract:

The waste emulsion after recycling,Which was acted as cooling and lubrication in the mechanicalProcessing,can be discharged when it reaches the goal of envirmental protection.The emulsion contains a large number of surfactants and other additives,so this Emulsifying Wastewater is quite stable.However, There is the higher cost in the existing approach of processing.It was reported that The pulse electrolytic process can be used to carry on the treatment the waste emulsion in the text.So the influence on the waste emulsion chemical oxygen demand(COD) elimination rate effect by the factorsof pulse electrolysis were investigated ,such as the electric current size, width pole plate spacing and pH value. The results shown that the shown that: the electrolytic effect of the acidic and neutral media is better than alkaline conditions, electrode spacing can improve the electrolytic effect, and appropriate duty cycle, pulse frequency can play a pulse, not only enhance the electrolytic effect, but also eliminate the passivation effect; it will be effective to take suitable current density.
