8. The mixed liquid reflux device of the biochemical pond as claimed in claim 1, wherein the submersible water impeller is arranged in the anaerobic pond (5), the anoxic pond I (2), the anoxic pond II (3) and the anoxic pond III (4) and is arranged near each water through hole.
9. The method for using the mixed liquid reflux device of the biochemical pond as claimed in claim 1, wherein the method comprises:
the flow direction of the water flow is as follows: an anaerobic tank (5) → an anoxic tank I (2) → an anoxic tank II (3) → an anoxic tank III (4) → an aerobic tank (1);
water flow firstly flows into the anoxic tank I (2) from the anaerobic tank (5) through a first water through hole (10.1) between the anaerobic tank (5) and the anoxic tank I (2);
the water flow in the anoxic tank I (2) flows into the anoxic tank II (3) through a second water through hole (10.2) and a third water through hole (10.3) between the anoxic tank I (2) and the anoxic tank II (3);
the water flow in the anoxic tank II (3) flows into the anoxic tank III (4) through a fourth water through hole (10.4) between the anoxic tank II (3) and the anoxic tank III (4);
and finally, water flow in the anoxic tank III (4) flows into the aerobic tank (1) through a fifth water through hole (10.5) between the anoxic tank III (4) and the aerobic tank (1).
10. The method of claim 9, further comprising: refluxing the mixed solution: aerobic pool (1) → anoxic pool i (2); anoxic tank iii (4) → anaerobic tank (5);
the mixed liquor in the aerobic tank (1) flows back to the anoxic tank I (2) from the aerobic tank (1) through a reflux pump (8) and a first reflux pipe (7.1);
the mixed liquid in the anoxic tank I (2) flows into the anoxic tank II (3) through a second water through hole (10.2) and a third water through hole (10.3) between the anoxic tank I (2) and the anoxic tank II (3);
the mixed liquid in the anoxic tank II (3) flows into the anoxic tank III (4) through a fourth water through hole (10.4) between the anoxic tank II (3) and the anoxic tank III (4);
the mixed liquid in the anoxic tank III (4) flows back to the anaerobic tank (5) from the anoxic tank III (4) through the two reflux pumps (8), the second reflux pipe (7.2) and the third reflux pipe (7.3).
