The improved sedimentation tank comprises a No. 1 improved sedimentation tank and a No. 2 improved sedimentation tank, and aims to expand capacity and improve fault tolerance. The fault tolerance rate means that when one of the reforming sedimentation tanks fails, the other reforming sedimentation tank in the system works so as not to break down the system. The No. 1 modified sedimentation tank and the No. 2 modified sedimentation tank are mainly characterized in that a quadrangular pyramid-shaped concrete structure is arranged at the bottom of the sedimentation tank and used for slowing down the agglomeration speed of the underground wastewater after sedimentation, as shown in fig. 2.

The 3# standby sedimentation tank and the 4# common sedimentation tank are conventional sedimentation tanks which are not subjected to any transformation, and underground wastewater is connected with the 1# transformation sedimentation tank, the 2# transformation sedimentation tank and the 3# standby sedimentation tank through sewage pipelines; the 3# standby sedimentation tank is mainly used for storing mud water into the standby sedimentation tank when the underground mud water is large and the reforming sedimentation tank cannot be stored; the 4# common sedimentation tank mainly stores supernatant liquid from the 1# modified sedimentation tank, the 2# modified sedimentation tank and the 3# standby sedimentation tank and filtrate of muddy water treated by the plate-and-frame filter press.

The sludge tank is connected with the No. 1 modified sedimentation tank and the No. 2 modified sedimentation tank through sludge pipelines and is mainly used for receiving muddy water with higher mud content at the bottoms of the No. 1 modified sedimentation tank and the No. 2 modified sedimentation tank.

the underground wastewater enters a 1# reconstruction sedimentation tank and a 2# reconstruction sedimentation tank (the 1# and the 2# can be opened at the same time or can be prepared according to the wastewater amount), and as the underground wastewater has larger mud content and higher turbidity, the sediment is faster after entering, a high-pressure air pipe is connected, and the mud-water mixture of the sedimentation tank is stirred by using the air outlet of the air outlet hole on the air supply pipe 2 so as to slow down the natural sedimentation speed of mud water, and simultaneously ensure that the mud-water content of the mud water supplied to the mud tank is maintained above a certain concentration; because the sludge pipeline interfaces of the No. 1 modified sedimentation tank and the No. 2 modified sedimentation tank are positioned below the clear water pipeline interfaces, supernatant liquid with relatively low turbidity in the tanks automatically flows or is pumped to the No. 4 common sedimentation tank for secondary sedimentation through the clear water pipeline, lower-layer slurry with relatively high turbidity is pumped to the sludge tank for temporary storage through the sludge pipeline, is transferred to the plate-frame filter press for extrusion filtration after being transferred to the sludge tank, and the filtrate returns to the No. 4 common sedimentation tank for continuous sedimentation, is then sent to a water sump together with supernatant liquid of the No. 4 common sedimentation tank and is pumped to the ground surface for discharge; the mud blocks generated by the plate-and-frame filter press fall into a rail small mine car at the bottom of the plate-and-frame filter press, and when the mud blocks are filled into a car hopper, the rail small mine car utilizes the existing conveying system to convey the mud blocks to a waste rock yard on the ground surface.
