Construction waste treatment line and treatment method

The invention provides a construction waste treatment line and treatment method. The construction waste treatment line comprises a feeding device, a primary crushing device, a primary vibrating screen, a positive-pressure winnowing impurity removing device, an artificial picking device, a transition bin, a secondary crushing device and a negative-pressure winnowing impurity removal device which are arranged sequentially from front to back in the direction of the treatment scheme, and all the devices are connected through a conveying device. According to the treatment line and the treatment method, four impurity removing processes of muck screening, positive pressure winnowing, manual picking and negative pressure separation are sequentially carried out, the positive pressure winnowing is used for blowing down impurities in the large materials after the primary crushing and before the secondary crushing, a negative pressure separation technology is applied to the impurity removal of regenerated finished produc
