| Abstract: | The influence of the pulse power and the direct current power on the power consumption and the COD removal in wastewater electrolysis process was studied, and the causes of energy conservation and high efficiency of pulse-electrolysis in wastewater treatment were analyzed. The result shows that the pulse-current is more efficient than the direct-current to slow down the polarization of electrode, reduce the over voltage of electrode, and then reduce 15%~35% of the power consumption. And contrast to the direct current electrolysis, the pulse-electrolysis can make electrolysis decontaminating efficiency increase by 5%~7%, because the current efficiency is stabile and the Fe2+ can spread to the wastewater effectively. |
