Method for reducing zinc electrodeposition direct current power consumption

The invention discloses a method for reducing zinc electrodeposition direct current power consumption, which specifically comprises the following steps: mixing a new solution with an electrolytic waste solution to obtain a mixed electrolyte with Zn concentration of 62.0-65.5 g/L; the mixed electrolyte is fed into an electrolytic bath to be subjected to electrodeposition treatment until the Zn concentration in the electrolyte in the electrolytic bath is 59.2-63.5 g/L, waste electrolyte is discharged, and the circulation volume of the waste electrolyte is controlled to be 24-72 m < 3 >/h; and the discharged electrolytic waste liquid returns to the system for cyclic utilization. According to the method, the mixed electrolyte with high zinc concentration is subjected to electrodeposition, process parameters in the electrodeposition process are controlled, low zinc drop is achieved, and the current efficiency can be effectively improved and the resistance voltage drop can be reduced in cooperation with a large ele
