Wastewater treatment device, docking station and cleaning system

A docking station for a cleaning robot, wherein the docking station comprises a wastewater treatment device, the wastewater treatment device comprising:

• a wastewater tank, wherein a bottom surface of the wastewater tank comprises a discharge opening;
• a discharge channel disposed below the wastewater tank and in communication with the discharge opening to discharge waste generated by wastewater distillation;
• a waste treatment component comprising:
• a first blade disposed above the bottom surface of the wastewater tank, wherein the first blade is configured to crush the waste on the bottom surface when rotating around a rotation axis;
• a second blade fixed relative to the first blade and at least partially disposed in the discharge channel, wherein the second blade is configured to crush the waste on an inner wall of the discharge channel when rotating around the rotation axis.
