The embodiment of the invention discloses a building refuse treatment regeneration system, including a classification stacking, sorting processing system, a classification processing system and a plurality of storage bins, wherein, the classification processing system includes at least two parallel crushing screening process production lines and water circulating systems, each crushing screening process production line includes a feeder, crusher, as well as a screening machine connected in series in sequence, and a plurality of outlets of the screening machine are respectively connected to the plurality of storage bins through conveyor belts. By adoption of the building refuse treatment regeneration system of the embodiment of the invention, bricks, tiles, dust and sand and concrete blocks and the like in the building refuse can be divided into at least two production lines for parallel processing, which greatly enhancing the production efficiency and the purity of recycled aggregates, so that the recycled aggregates can be applied to a variety of uses, reproduced into a variety of high-quality recycled products, reducing the waste of resources and minimizing pollution that will be probably caused to the environment.
