The invention relates to a method for recycling and treating the salt water of pickled krault and is realized by the following steps: after the salt water is coarsely and then finely filtered, the residue is dried and used as boiler fuel, the filtrate enters into triple effect concentration, the saturated salt solution of the condensed juice is pumped into a crystallizer for crystallization, and salt is obtained after centrifugal separation, and the liquid after centrifugation is hydrolyzed, discolored, deodorized, filtered, prepared, filled and sterilized to obtain vegetable amino acid. The invention has simple operation and no regeneration of waste, the recycled residue can be used as the boiler fuel, the salt and the vegetable amino acid can be used as food and chemical fuel, thus eliminating the pollution of the salt water of pickled krault to environment.
