the floater recovery tank is connected with the floater discharge pipe and is used for storing floaters discharged by the floater discharge pipe;

the sediment recovery tank is connected with the sediment discharge pipe and is used for storing sediment discharged by the sediment discharge pipe.

3. The water treatment device of claim 1, further comprising a ball float and a ball float;

one end of the ball lever is connected with the side surface of the first cavity, and the other end of the ball lever is connected with the floating ball;

the floating ball is arranged below the water inlet, and when the water level in the first cavity rises to the top surface of the first cavity, the floating ball is in contact with the water inlet and is used for blocking the water inlet.

4. The water treatment device of claim 3, wherein a rotating shaft is arranged on the side surface of the first cavity;

the rotating shaft is connected with one end of the ball-cock stem.

5. The water treatment device of claim 4, wherein the rotating shaft is disposed above the float discharge port.

6. The water treatment device of claim 1, further comprising a second drain pipe;

7. The water treatment device of claim 6, further comprising a self-regulating valve;

one end of the automatic control valve is connected with the water inlet pipe, and the other end of the automatic control valve is connected with the second water drainage pipe;

the automatic control valve is used for discharging the water in the water inlet pipe into the second water discharge pipe when the pressure of the water in the water inlet pipe exceeds a first pressure threshold value.

8. The water treatment device of claim 1, further comprising a control valve, a first drain valve, a second drain valve, and a third drain valve;

the control valve sets up on the inlet tube, first blow-off valve sets up on the first blow-off pipe, the second blow-off valve sets up on the floater discharge pipe, the third blow-off valve sets up on the sediment discharge pipe.

9. The water treatment device of claim 1, further comprising a fan;

the fan is arranged in the first cavity and used for blowing the floater to the floater discharging pipe.

10. A water treatment system comprising a production facility and a water treatment apparatus as claimed in any one of claims 1 to 9;

and a third discharge port is arranged on the production equipment and is connected with the water inlet pipe.
