The invention discloses a wet recovery method of a waste aluminum substrate and a heavy metal waste liquid concentration process thereof. The wet recovery method of the waste aluminum substrate and the heavy metal waste liquid concentration process thereof comprise the steps that the waste aluminum substrate is discharged; the aluminum substrate after discharge treatment is disassembled, and copper foil and aluminum foil of the aluminum substrate are disassembled and unfolded; the disassembled copper foil is immersed in a temperature-controlled water washing pool to obtain the copper foil, thealuminum foil and waste water containing a large amount of impurities; waste water containing the impurities is recovered; waste water containing a large amount of heavy metal is concentrated; and concentrated liquid is electrolyzed. According to the wet recovery method of the waste aluminum substrate and the heavy metal waste liquid concentration process thereof, the waste aluminum substrate isdecomposed in a recycling mode, by using the working procedures of discharge, disassembly, pulverization, sorting and the like, the working procedures in the process are researched optimally, the process flow is integrated and reduced, the complexity of process operation is reduced, recovery cost is reduced, cleaner production is carried out, and certain economic benefits are further created.
