A recuperation treatment method of penetrating and discolor logs belongs to wood processing technology field. It is characterized by the following steps: 1) oxygenizing the penetrating and discolor logs in hydrogen dioxide solution which concentration is of 5 ~ 10 g / L and pH is 10-11, the treating temperature is 80 ~ 98 degree C and soaking time is 1 ~ 3h; 2) deoxidizing the treated penetrating and discolor logs in step 1) in deoxidization enzyme solution which concentration is 0.4~0.6g / L and pH is 5.5-6.5, the temperature is 55 to 65 degree C and soaking time is 0.8 ~ 1.2h. The invention method recuperates penetrating and discolor logs, can recovery the penetrating and discolor logs thin slices to original natural fresh cut-state, and its main components such as cellulose structure are not damaged, so the logs thin slice can be colored in the process of dyeing uniformly. The program has low dealing cost and the reduction action is obvious, it can be used in the mass production of wood processing.
