Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a filter media and an ecological pond. Background Technology

[0002] As a composite biological treatment device, the ecological pond integrates multiple treatment units such as anaerobic, anoxic, and aerobic treatment, and has been widely used in municipal sewage, industrial wastewater, and decentralized rural sewage treatment.

[0003] An ecological pond includes anaerobic treatment, aerobic treatment, and filtration treatment. Wastewater enters the ecological pond and undergoes anaerobic and aerobic treatment sequentially, followed by filtration. Only after the treatment is complete is the wastewater discharged. In existing ecological ponds, filtration typically involves laying filter media such as crushed stone or carbon layers within the filtration tank. For example, patent application CN116835793A discloses a wastewater treatment system that uses a filter tank formed by laying crushed stone or carbon layers. However, this method is inefficient and difficult to standardize. Utility Model Content

[0004] This invention provides a filter media and an ecological pond, which solves the problem of low laying efficiency of existing filter media.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A filter media for use in the filtration tank of an ecological pond includes a media body comprising a plurality of particles bonded together by an adhesive to form an integrated whole; and some of the bonded particles have gaps between them to form filtration channels for water circulation.

[0007] In a preferred embodiment, the packing body includes a main body section and a secondary body section. The main body section is located at the upper part of the packing body, and the secondary body section is located at the lower part of the packing body. The main body section and the secondary body section are connected by a transition section.

[0008] In a preferred embodiment, the width of the sub-body segment is smaller than the width of the main body segment in the direction of water flow, thereby forming a buffer space below the main body segment and on both sides of the sub-body segment.

[0009] In a preferred embodiment, the two sides at both ends of the main body segment in the width direction are respectively second sides, the second sides are inclined, and the distance between the two second sides gradually increases from bottom to top.

[0010] In a preferred embodiment, the two sides at both ends of the packing body in the thickness direction are respectively the first side, the first side is inclined, and the distance between the two first side gradually increases from bottom to top.

[0011] In a preferred embodiment, the packing body is further provided with a vent pipe, one end of which extends into the interior of the packing body and the other end is located on the outside of the packing body.

[0012] In a preferred embodiment, the vent pipe has several vent holes.

[0013] In one preferred embodiment, a plurality of planting positions are provided in the recess on the upper side of the main body segment.

[0014] In a preferred embodiment, the bottom of the planting position is below the highest water level of the filtration tank.

[0015] This utility model also provides an ecological pond, which includes a filter pond in which the filter packing material is disposed; and the inlet of the filter pond is disposed below the side of the packing material body, and the outlet of the filter pond is disposed above the other side of the packing material body.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] (1) The filter media of this utility model has an integrated structure, which can be placed into the filter tank in one operation, greatly improving the efficiency of media installation. In addition, it can realize industrial pre-processing of the media body, improving the manufacturing effect of the media body itself.

[0018] (2) The filter media of this utility model includes a main body section and a secondary body section. The width of the secondary body section is smaller than that of the main body section, so that a buffer space is formed below the main body section and on both sides of the secondary body section. First, setting up a buffer space can reduce the weight and material usage of the filter media body, thus reducing costs. More importantly, the buffer space on one side of the secondary body section is connected to the inlet of the filter tank, which allows water to enter the filter tank quickly. Moreover, the buffer space is set up to accommodate water and prevent the water from being blocked in the filter tank.

[0019] (3) The filter packing of this utility model has both the first and second sides inclined. On the one hand, the side of the packing body can fit well with the inner side of the filter tank, so that the two can fit together better; on the other hand, if the packing body is made by mold, it can be demolded better.

[0020] (4) The filter media of this utility model has several planting positions recessed on the upper side of the main body. The planting positions are used to grow plants to optimize the utilization of wastewater.

[0021] (5) The ecological pond of this utility model includes the filter media and has the beneficial effects brought by the filter media. Moreover, in the filter pond, the inlet of the filter pond is set below the side of the filter media body, and the outlet of the filter pond is set above the other side of the filter media body. After the water enters the filter pond through the inlet, the water will flow through the maximum stroke to the outlet. The water can flow through a large stroke in the filter media body, which improves the filtration effect of the filter media body on the water.

[0022] Other technical problems that the filter media and ecological pond of this utility model can solve, other technical features contained in the technical solution, and the advantages brought by these technical features will be further explained in detail with reference to the accompanying drawings.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0034] This application provides an ecological pond for sewage treatment, in which the treated sewage is directly discharged or used for irrigation, etc.

[0035] like Figure 5 As shown, the ecological pond specifically includes a filtration pond 3, an anaerobic pond 1, and an aerobic pond 2. Specifically, the ecological pond has an inlet and an outlet, with the anaerobic pond 1, aerobic pond 2, and filtration pond 3 arranged sequentially between the inlet and outlet, and the outlet of the ecological pond is also the outlet of the filtration pond 3.

[0036] Wastewater typically enters the anaerobic tank 1 through the inlet of the ecological pond, then proceeds through the aerobic tank 2 and the filtration tank 3 for further treatment, before finally flowing out through the outlet of the ecological pond. The anaerobic tank 1 has a low dissolved oxygen content, primarily due to the decomposition of complex organic matter by anaerobic microorganisms. The aerobic tank 2 requires aeration to provide oxygen and increase the dissolved oxygen content, allowing aerobic microorganisms to completely decompose the organic matter. Finally, the filtration tank 3 performs a final filtration of the wastewater.

[0037] This application also provides a filter media for use in a filter tank 3 of an ecological pond. The filter tank 3 has an inlet and an outlet. The filter media includes a media body 4. When the filter media is placed in the filter tank 3, the inlet of the filter tank 3 is located below the side of the media body 4, and the outlet of the filter tank 3 is located above the side of the media body 4. In a preferred embodiment, the filter tank 3 is generally rectangular, with the inlet located at the lower right and the outlet located at the upper left, and the inlet and outlet of the filter tank 3 are diagonally opposite each other. In other cases, the inlet of the filter tank 3 can also be located at the lower left and the outlet at the upper right. With this arrangement of the inlet and outlet of the filter tank 3, when water from the aerobic pond 2 enters the filter tank 3 through the inlet, the water will flow through a maximum distance to the outlet, allowing the water to travel a greater distance through the media body 4, thus improving the filtration effect of the media body 4.

[0038] Combination Figure 1 Specifically, in this embodiment, the filter media includes a median body 4, which comprises several particles bonded together with an adhesive to form an integrated whole. Furthermore, some of the bonded particles have gaps between them, forming filter channels for water flow. When water flows to the median body 4, it fills the filter channels, thus achieving water filtration and purification.

[0039] In a preferred embodiment, the particulate matter is ceramsite, which is lightweight, has strong adsorption capacity, and excellent pollution interception ability. It should be noted that in other embodiments, other granular materials can also be used, such as perlite, crushed stone, etc.

[0040] Regarding the adhesive, in a preferred embodiment, the adhesive is a cement slurry, which is mixed into the granules and stirred, and finally shaped and cured to form an integral filler body 4. The slurry can be shaped using any existing method.

[0041] In this design, the packing body 4 is an integrated structure. Compared to the existing method of laying granules, the integrated structure of the packing body 4 allows for a single, one-time placement into the filter tank 3, significantly improving the packing installation efficiency. Furthermore, it enables industrial pre-processing of the packing body 4, enhancing its manufacturing quality.

[0042] Combination Figure 1 and Figure 2As shown, the packing body 4 includes a main body section 41 and a secondary body section 43. The main body section 41 is located at the upper part of the packing body 4, and the secondary body section 43 is located at the lower part of the packing body 4. The main body section 41 and the secondary body section 43 are connected by a transition section 42. The packing body 4 is disposed in the filter tank 3, and the secondary body section 43 is supported at the bottom of the filter tank 3. In other embodiments, the main body section 41 can also be supported by the side wall of the filter tank 3.

[0043] For ease of explanation, combined with Figure 1 As shown, the packing body 4 has a thickness direction, a width direction, and a height direction. The height direction is the vertical direction in which the packing body 4 is disposed in the filter tank 3; the water flows from one side of the packing body 4 to the other side in the filter tank 3, and the horizontal direction through which the water flows is the width direction of the packing body 4; the thickness direction of the packing body 4 is perpendicular to its width and height directions.

[0044] Preferably, in the width direction of the packing body 4, the width of the secondary section 43 is smaller than the width of the main section 41, so that a buffer space 45 is formed below the main section 41 and on both sides of the secondary section 43. First, setting the buffer space 45 can reduce the weight and material usage of the packing body 4, thus reducing costs; more importantly, the buffer space 45 on one side of the secondary section 43 is connected to the inlet of the filter tank 3, which allows water to enter the filter tank 3 quickly; and the buffer space 45 is set to accommodate water and prevent water from being blocked.

[0045] Because the widths of the secondary segment 43 and the main segment 41 are inconsistent, they are connected by a transition segment 42. See Figure 2 In the middle, the sides of the transition section 42 at both ends in the width direction are inclined to connect the sub-body section 43 and the main body section 41.

[0046] In one case, see Figure 2 and Figure 3 As shown, the sides at both ends of the main body section 41 in the width direction are designated as second side surfaces 401. The second side surfaces 401 are inclined, and the distance between the two second side surfaces 401 gradually increases from bottom to top. Additionally, the sides at both ends of the packing body 4 in the thickness direction are designated as first side surfaces 400. The first side surfaces 400 are inclined, and the distance between the two first side surfaces 400 gradually increases from bottom to top. The inclined arrangement of both the first side surfaces 400 and 401 allows the sides of the packing body 4 to better fit with the inner surface of the filter tank 3, resulting in a better fit. Furthermore, if the packing body 4 is manufactured using a mold, it allows for better demolding.

[0047] like Figure 2As shown, a vent pipe 44 is also provided on the packing body 4. One end of the vent pipe 44 extends into the interior of the packing body 4, and the other end is located on the outside of the packing body 4. Several vent holes 404 are opened on the vent pipe 44. The gas released from the water in the filter tank 3 and the packing body 4 is discharged in a timely manner through the vent pipe 44.

[0048] like Figure 4 As shown, several planting positions 40 are recessed on the upper side of the main body section 41. These planting positions 40 are used for planting plants, optimizing wastewater utilization. Furthermore, the bottom of the planting positions 40 is lower than the highest water level of the filter tank 3, allowing the plant roots to fully absorb water and extend into the packing material body 4, absorbing more organic or inorganic matter from the water, further purifying the water. It should be noted that the highest water level of the filter tank 3 is related to the outlet position of the filter tank 3, and the depth of the recessed planting positions 40 can be set according to the outlet position of the filter tank 3.

[0049] In this scheme, filter media are installed in the filter tank 3 to filter and purify sewage; the filter media body 4 is an integrated structure, which greatly improves the efficiency of the filter media in the filter tank 3.

[0050] The terms "installation," "setup," "equipped with," and "connection" used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0051] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
