[0044] like Figure 1-7 As shown, an ecological filtration dam of the utility model comprises a dam body 1, which is arranged in a pond 2, and its width is not less than 2m. A sedimentation tank, an aeration tank, and a biological purification tank are also arranged in the pond 2, wherein the dam body 1 is arranged between the sedimentation tank and the aeration tank, or between the aeration tank and the biological purification tank;

[0045] The dam body 1 includes four retaining walls 11, an adsorption unit 12 and an aisle plate 13, wherein:

[0046] Four retaining walls 11 are connected end to end to form a square frame 101, two of which are against the pond embankment 201, that is, the retaining walls 11 here are built close to the pond embankment 201, and the other two retaining walls 11 span the construction water area and are built with porous bricks 111. Figure 2 As shown, the hole direction of the porous brick 111 is parallel to the water flow direction, wherein the size of the porous brick 111 is 240mm×115mm×90mm. This structure effectively improves the structural strength of the dam body 1, making the ecological filtration dam suitable for use in ponds with larger spans.

[0047] In addition, in order to improve the supporting capacity of the square frame 101, the retaining wall 11 across the construction water area is built with two rows of porous bricks 111. At the same time, a steel concrete foundation 14 is set at the bottom of the retaining wall 11, wherein the steel concrete foundation 14 is cast at the bottom of the pond 2, and the retaining wall 11 is built on the top of the corresponding steel concrete foundation 14.

[0048] The adsorption unit 12 is placed inside the square frame 101 to absorb debris in the water. The adsorption unit 12 includes the following two embodiments.

[0049] Embodiment 1: The adsorption unit 12 includes a plurality of ceramic filling units 121, and the plurality of ceramic filling units 121 are stacked inside the square frame 101, wherein the ceramic filling unit 121 includes a rectangular nylon woven bag 1211 and ceramic particles 1212, and the ceramic particles 1212 are filled in the nylon woven bag 1211, and the particle size thereof is 15 to 30 mm. When the ceramic filling unit 121 in the square frame 101 needs to be replaced and maintained, each ceramic filling unit 121 is taken out one by one, and then corresponding replacement or maintenance operations are performed, and then the ceramic filling unit 121 is restacked in the square frame 101.

[0050] Embodiment 2: The adsorption unit 12 includes a plurality of ceramic filling units 121 and a mesh basket 122, wherein the plurality of ceramic filling units 121 are stacked inside the mesh basket 122; the mesh basket 122 is placed inside the square frame 101, and a plurality of second hanging holes 1201 are provided on the top of the mesh basket 122. When it is necessary to replace and maintain the ceramic filling units 121 in the square frame 101, the hook of the external crane is hung on the second hanging hole 1201, and the mesh basket 122 together with the ceramic filling units 121 therein are lifted out of the square frame 101 by the crane, and then the ceramic filling units 121 are replaced or maintained from the mesh basket 122, and then the ceramic filling units 121 are stacked again in the mesh basket 122, and the mesh basket 122 is placed into the square frame 101 by the crane.

[0051] The above two embodiments are convenient for replacing and maintaining the ceramic filler unit 121 in the square frame 101. In addition, in the above two embodiments, the ceramic particles 1212 can be replaced by one or more of volcanic rocks, fine sand, crushed stone, brown flakes and activated carbon.

[0052] In order to facilitate the passage of people or vehicles across the water area, an aisle plate 13 is set on the top of the square frame 101. The aisle plate 13 is a steel concrete structure. The aisle plate 13 provides conditions for the passage of people or vehicles, facilitates agricultural vehicles to transport agricultural supplies, and makes the ecological filtration dam more suitable for use in ponds with larger spans.

[0053] Meanwhile, in order to facilitate the replacement and maintenance of the ceramic filler unit 121 , the aisle plate 13 is detachably arranged on the top of the square frame 101 .

[0054] The aisle plate 13 includes a steel concrete plate 131 and a hook 132, wherein the steel concrete plate 131 is placed on the top of the square frame 101, and a plurality of first hanging holes 1301 are arranged on the top of the steel concrete plate 131; one hook 132 is fixed in each of the first hanging holes 1301. When the aisle plate 13 needs to be disassembled, the hook of the crane is hooked with the first hanging hole 1301, and then the aisle plate 13 is lifted off the dam top by the crane. After maintenance, the aisle plate 13 is placed on the dam top by the crane.

[0055] The use method of an ecological filter dam of the utility model is as follows:

[0056] When constructing the pond 2, two retaining walls 11 are built at the bottom of the pond 2 and near the pond bank 201, and then the other two retaining walls 11 are built in the direction across the water area using porous bricks 111. The four retaining walls 11 are surrounded to form a square frame 101, and then the adsorption units 12 are stacked in the square frame 101, and finally the aisle plate 13 is placed on the top of the square frame 101.

[0057] During use, below the normal water level, the ceramic packing units 121 are placed horizontally one by one. Above the normal water level, the ceramic packing units 121 can be appropriately reduced according to the increase and duration of the water level during the annual flood season. This can reduce construction and material costs while ensuring the filtering effect, thereby saving investment.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
