The invention discloses a PVC pipe environment-friendly collection and treatment device which comprises a work box and a belt. The top of the work box communicates with a feeding hopper. The two sides of the top of an inner cavity of the work box are fixedly connected with heating blocks. The two sides of the work box are fixedly connected with first supporting plates. One side of the top of each first supporting plate is fixedly connected with a first motor. A rotary shaft of each first motor is sleeved with a first gear. According to the PVC pipe environment-friendly collection and treatment device, through cooperative use of the work box, the belt, the feeding hopper, the heating blocks, the first motors, first rolling shafts, second rolling shafts, first crushing blades, second crushing blades, partition plates, first grinding rollers, a second grinding roller, a second motor, a second belt disc, a collecting box and a discharging opening, discarded PVC pipes can be collected and then crushed and grounded to become powder, and the discarded PVC pipes can be recycled and processed more conveniently; and therefore resources are saved, the environment cannot be polluted, and the existing green economy requirement is met.
