The utility model discloses a bidirectional filtering head of an upward flow aeration biological filtering tank. The utility model comprises an upper filtering cap (1) and a filtering rod (3), wherein the upper filtering cap (1) is connected with one end of the filtering rod (3) to form an integral body. The utility model has the structural characteristic that the other end of the filtering rod (3) is connected with a lower filtering cap (5) which forms a grid type spherical shape. The other end of the filtering rod arranged on a filtering plate of a filtering tank is provided with the lower filtering cap (5), thereby, solid suspended substances in a large quantity are intercepted outside the lower filtering cap. Consequently, the utility model has the advantages of convenient clearing, enhanced filtration effect of the upper filtering cap (1), increased production efficiency of water treatment and reduced operation cost of water treatment.
