Wherein the water body area 3 is used for accommodating water bodies, and the biological stuffing 10 is used for biological treatment.
In the scheme of the utility model, the following steps are provided: a biological treatment area 2 is arranged between the embankment 1 and the water body area 3, and can separate the embankment 1 from the water body area 3, so that pollutants entering the pond from the outside of the pond (such as the embankment 1) can be trapped or blocked in the biological treatment area 2; the biological treatment area 2 is internally provided with a biological filler 10, and the biological treatment capacity of the biological filler 10 is utilized to carry out biological purification treatment on the pollutants so as to be dissolved in the biological treatment area 2 and avoid polluting the water body area 3.
Further, by arranging the isolation component 20 at the junction of the water body region 3 and the biological treatment region 2, the isolation component 20 blocks the biological filler 10 in the biological treatment region 2, prevents the biological filler 10 and/or the pollutants from entering the water body region 3, and simultaneously allows the water body region 3 and the biological treatment region 2 to exchange fluid, so that the dissolved oxygen of the water body in the biological treatment region 2 is consistent with the dissolved oxygen of the water body in the water body region 3, thereby providing more suitable dissolved oxygen environment and larger action area for microorganisms on the biological filler 10, avoiding additional arrangement or power circulation arrangement, avoiding operation cost or operation power and simplifying maintenance management of the whole ecological restoration system 100.
Based on the analysis, the ecological restoration system 100 of the rural pond can block or digest the pollutants flowing into the biological treatment area 2 from the embankment 1, prevent the water area 3 from being polluted, does not consume power cost, and is very suitable for rural ponds.
Referring to fig. 1, the biological treatment area 2 is entirely surrounded by the water area 3. Illustratively, the plane shape of the water body area 3 is circular in the horizontal plane, and the biological treatment area 2 is annular. It should be noted, however, that the specific shape of the water body region 3 and the biological treatment region 2 according to the present utility model is not limited thereto. For example, in other embodiments, the planar shape of the body of water 3 may be square or other irregular shape.
Referring to fig. 2, in the present embodiment, the water surface of the biological treatment area 2 is located below the water surface of the water body area 3 in the vertical direction (the water depth direction). In other words. The water surface of the biological treatment area 2 is lower than the water surface of the water body area 3.
Further, the width L of the water surface of the biological treatment area 2 is 1m in the direction from the bank 1 to the water body area 3. In this way, by defining the size of the water surface width L of the biological treatment zone 2, the barrier and digestion effect of the biological treatment zone 2 against contaminants is ensured.
It should be noted, however, that the embodiment of the biological treatment zone 2 of the present utility model is not limited thereto. In a specific implementation, the width L of the water surface of the biological treatment area 2 can be adaptively adjusted according to the polluted water surface area and the water depth of the pond. For example, in some embodiments, the width L of the water surface of the biological treatment zone 2 may be greater than 1m, and in other embodiments, the width L of the water surface of the biological treatment zone 2 may be less than 1m.
In some embodiments, the biologic filler 10 includes a first filler section, a second filler section, and a third filler section arranged in sequence from top to bottom. According to the vertical distribution characteristics of the dissolved oxygen of the water body, the first filler section is configured as an aerobic layer for performing an aerobic reaction, the second filler section is configured as an anoxic layer for performing an anoxic reaction, and the third filler section is configured as an anaerobic layer for performing an anaerobic reaction.
In the actual operation process, a large number of microorganisms with the function of purifying water quality are respectively attached to the aerobic layer, the anoxic layer and the anaerobic layer through natural film hanging. At this time, under the action of microorganisms in each layer, the pollutants entering the biological treatment area 2 from the outside of the pond are purified or digested by the actions of oxidative decomposition, ammoniation, nitrification, denitrification and the like of the organic pollutants, so that the pollutants are prevented from being diffused into the water body area 3.
In particular implementations, the first, second, and third filler segments are the same material.
Further, the biological filler 10 is shale ceramsite, and the shale ceramsite is suitable for being used as a carrier of microorganisms for purifying water. Further, the particle size of the shale ceramsite is 5mm-8mm.

At this time, the roots of the hydroponic plants 40 are positioned under the water surface of the bio-filler area 2 and planted on the upper surface of the bio-filler 10.
Further, the hydroponic plant 40 is selected from hydroponic vegetables. The hydroponic vegetables can develop root systems and have good nitrogen and phosphorus absorption and removal effects, and are a common type in rural areas. For example, the hydroponic vegetables are selected from herba Lophatheri and herba Oenanthes Javanicae. It should be noted that, in order to ensure a better dirt removal effect, the seeds should be updated or reseeded in time after picking.

In practice, the bottom of the fixing member 22 protrudes beyond the bottom end of the isolation net 21 by a dimension and is specifically limited so as to ensure that the fixing member 3 is inserted into the bottom of the pond or the depth of the bank 1, so that the fixing member is not deformed or inclined when the load of people and animals exists on the biological treatment area 2.
Specifically, the isolation net 21 and the fixing member 22 are fixedly connected by a connecting member 23. The fastener 33 may be, but is not limited to, a metal rivet.
In specific implementation, the isolation net 21 is a steel wire net with good corrosion and rust prevention functions. The isolation net 21 has a cylindrical shape with both ends open. The fixing member 22 is a wooden stake. The cross section of the wood pile is circular. The diameter of the wood pile is 10cm. It should be noted that the specification or structure of the stake is not limited thereto. For example, in some embodiments, the diameter of the stake may be 9cm or 11cm in order to increase the strength of the stake.

Schematically, as shown in fig. 4, the flow-through assembly 30 includes a main conduit 31 and a plurality of extension conduits 32. The main pipe 31 is buried in the biological filler 10 and extends in the extending direction of the dividing line. The plurality of extension pipelines 32 are arranged at intervals along the extension direction of the main pipeline 31, each extension pipeline 32 is in fluid communication with the main pipeline 31 and extends along the direction from the embankment 1 to the water body area 3, one end of the extension pipeline 32 is positioned in the water body area 3, and the other end of the extension pipeline 32 is positioned in the biological treatment area 2.
