Non-poaching-water common hot-dip galvanizing technique

The invention relates to a hot-dip galvanizing process, in particular to a common hot-dip galvanizing process without rinse water, which aims to solve the technical problems existing in prior art that after being treated, if industrial wastewater which is produced during hot-dip galvanizing is discharged reaching the standard, galvanizing needs to consume a large number of water source, and the treatment cost is greatly increased and the like. The steps of common hot-dip galvanizing process without rinse water of the invention comprises degreasing, cleaning and plating auxiliary, wherein to-be-galvanized workpieces are dipped in assisted plating solution, whose components are aqueous solution of ZnCl2 and NH4Cl, the PH valve of the assisted plating solution is adjusted through adding ammonia water, then Fe2+ on the surface of the workpiece is changed into Fe3+ through hydrogen peroxide solution, and then the Fe3+ is filtered out through a filter purification device, a layer of assisted plating film is formed on the surface of the workpiece, drying, hot-dip galvanizing, cooling and inactivating.
