The invention discloses a broke disposal and recovery technology and system. Broke can be thoroughly disintegrated into clean broke pulp containing no broke scraps, and the accident that pulp blocks equipment can be effectively avoided due to reasonable design and smooth operation. The broke disposal and recovery technology comprises steps as follows: different kinds of broke are pumped into a broke pulp tower after being stirred and broken; broke pulp is pumped to a high-concentration sand remover for sand removal, broke pulp with heavy impurities removed is discharged from the high-concentration sand remover and enters a disintegrater, and broke scraps in the broke pulp are thoroughly disintegrated into pulp through dissociation by the disintegrater; the broke pulp containing no broke scraps enters a pressure screen under the effect of pulp discharging pressure, and accept obtained by screening with the pressure screen enters a broke pulp tank. The broke disposal and recovery system comprises a hydrapulper,
