The invention relates to the technical field of machine-made sand production, in particular to a machine-made sand washing system and method capable of recovery wastewater. The sand washing system comprises: a sand washing subsystem comprising a sand washing device; a sewage recovery subsystem comprising a first sedimentation tank, a second sedimentation tank and a recovery tank which are connected in sequence, wherein a first feeding device for feeding a flocculating agent and a second feeding device for feeding a deflocculating agent are arranged above the first sedimentation tank and the second sedimentation tank respectively, the first sedimentation tank is connected with the drainage end of the sand washing device, and the recovery tank is connected with the water inlet end of the sand washing device, so that sewage generated by the sand washing device sequentially flows through the first sedimentation tank and the second sedimentation tank to be treated, then is discharged to the recovery tank and is ci
