[0036] Working principle:

[0037] The sludge water is discharged into the sludge water separation tank through the drainage channel 10. Part of the drainage of the sludge dewatering machine enters the sludge water separation tank through the drainage channel 10. After the sludge is discharged, the push-flow agitator 1 is started. Because the drainage of the sludge dewatering machine contains a flocculating agent, the flocculating agent can be fully mixed and uniformly distributed with the sludge water after the agitator is agitated. After a certain period of agitation, the agitator can be closed. After a period of time, the moisture in the sludge gradually decreases, and the particles gradually coagulate to form concentrated sludge that settles at the bottom.

[0038] The mud-water separation tank is provided with a partition wall 3, and the partition wall 3 is provided with a plurality of drainage valves 5.

[0039] After the upper clarified liquid is discharged, the drainage electric valve can be closed, the concentrated sludge in the sludge tank is transported to the stacked screw sludge dewatering machine by a sludge pump 7 for disposal, and meanwhile, the plug flow agitator 1 can be opened to assist the sludge pump 7 to discharge sludge more uniformly and stably.

[0040] In summary, the underground mud-water separation tank has a small area, the drainage pump, the agitator and the drainage valve 5 can be automatically controlled remotely during operation, flocculation can be directly performed by using part of the drainage of the sludge dewatering machine, the consumption of chemicals is reduced, in addition, the mud-water separation effect can be achieved by using part of the drainage of the sludge dewatering machine without arranging a large amount of auxiliary equipment, and the valve at different positions of the partition wall 3 can discharge and recycle clean water according to the actual sludge height.
