[0040] The working principle of the above embodiment is:

[0041] (1) Before using the purification equipment, the concrete production wastewater can be passed through a grid to remove large particles of impurities in the wastewater, and then a high-efficiency sedimentation tank is used for physical precipitation to remove suspended matter in the wastewater.

[0042] (2) The filter screen 6 provided can filter out fine particles and colloidal substances after the flocculant and sewage are mixed, and the activated carbon layer 7 provided can perform adsorption treatment. When the filter screen 6 and the activated carbon layer 7 are to be replaced, the threaded rod 84 can be rotated, and the rotation of the threaded rod 84 drives the movable plate 82 to move toward the side close to the fixed plate 83.
