PURPOSE: An electrolysis purification treatment method of wastewater is provided to minimize unnecessary power consumption, and to prevent the generation of untreated source water as the appropriate power is supplied even if the contamination load increases. CONSTITUTION: An electrolysis purification treatment method of wastewater uses an electrolysis purification facility. The electrolysis purification apparatus comprises an electrolysis processing basin(10), a direct current supply(31), and a power supply controller(30). The concentration of residual free chlorine of treated water discharged after purification by electrolysis in an electrolysis treatment basin is measured using a residual free chlorine meter(40). The electric energy supplied to DC supply is reduced using the power supply controller so as to be inversely proportional to measured concentration of the residual free chlorine. The concentration of residual free chlorine is divided into multiple sections. The respectively different electric energy is allocated to each section.
