Description

Technical Field

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

[0002] Ecological ponds, as a type of composite biological treatment device, integrate multiple treatment units such as anaerobic, anoxic, and aerobic processes, and are widely used in municipal sewage, industrial wastewater, and decentralized rural sewage treatment. Among them, the anaerobic treatment unit, as the core component of the ecological pond, undertakes key functions such as hydrolysis acidification, organic matter decomposition, and denitrification, and its operational efficiency directly affects the treatment efficiency of the entire system.

[0003] In existing technologies, wastewater in traditional anaerobic tanks enters the tank through a distribution system and undergoes pollutant degradation under the action of anaerobic microorganisms. However, in actual operation, it has been found that effective interception is difficult in anaerobic tanks when treating wastewater containing large particulate impurities such as fibers, fruit shells, or inorganic gravel. Unintercepted suspended solids, moving with the water flow within the tank, easily accumulate in subsequent structural parts. For example, when the effluent enters subsequent treatment units, the particulate matter can easily cause pipe blockages. Utility Model Content

[0004] This invention provides an ecological pond that intercepts large particulate impurities in wastewater in an anaerobic pond, thus preventing them from affecting subsequent wastewater treatment.

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

[0006] An ecological pond includes an anaerobic pond, wherein an inlet is provided on one side of the anaerobic pond and an outlet is provided on the other side.

[0007] At least one filter layer is also provided in the anaerobic tank, and the filter layer is located between the inlet and the outlet of the anaerobic tank.

[0008] The filter layer includes two opposing filter surfaces, and the other sides are connecting surfaces. The filter surfaces are in contact with the wastewater, which enters the filter layer through one of the filter surfaces and then flows out through the other filter surface. One of the connecting surfaces is a connecting surface. The anaerobic tank has an opening, and the connecting surface is located close to and facing the opening of the anaerobic tank. The other connecting surfaces are close to the sides of the anaerobic tank.

[0009] As a further improvement, the filter surfaces are located at both ends of the filter layer in the thickness direction, and the thickness of the filter layer is 5-50mm.

[0010] As a further improvement, the filter layer has a number of filter holes distributed regularly or irregularly.

[0011] As a further improvement, the average size of the filter pores is 2-10 mm.

[0012] As a further improvement, when two or more filter layers are provided, the average size of the filter pores of the filter layers gradually decreases from the inlet to the outlet of the anaerobic tank.

[0013] As a further improvement, the end of the inlet near the interior of the anaerobic tank is connected to an inlet pipe, and the outlet of the inlet pipe extends to the bottom of the anaerobic tank.

[0014] As a further improvement, the anaerobic tank is also equipped with packing material, one end of which is connected to one side wall of the anaerobic tank, and the other end is connected to the opposite side wall of the anaerobic tank.

[0015] As a further improvement, the packing material includes a first packing material and a second packing material, wherein the first packing material is disposed near the inlet and the second packing material is disposed near the outlet of the anaerobic tank.

[0016] As a further improvement, the outlet of the anaerobic tank is connected to the aerobic tank, and a filtration tank is set on the other side of the aerobic tank.

[0017] As a further improvement, a cover assembly is provided at the opening of the anaerobic tank and the aerobic tank. The cover assembly includes a main cover that covers the opening of the anaerobic tank and the aerobic tank, and a ventilating pipe is connected to the main cover.

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] (1) The ecological pond of this utility model mainly sets up a filter layer in the anaerobic pond to filter and clean large particulate impurities in the sewage that are difficult to decompose. Moreover, after the filter layer is set in the anaerobic pond, the connection surface close to the side of the anaerobic pond is close to the side of the anaerobic pond, so that the sewage flowing in through the inlet can be filtered by the filter layer to the greatest extent.

[0020] (2) The ecological pond of this utility model has a filter layer thickness that takes into account both the effect of filtering sewage and the reduction of the impact on sewage treatment efficiency.

[0021] (3) The ecological pool of this utility model has several filter holes distributed in the filter layer. While filtering impurities, the filter holes can also contain and adsorb impurities.

[0022] (4) The ecological pool of this utility model can be equipped with multiple filter layers to filter impurities in sewage in a layered manner and improve the sewage purification effect.

[0023] (5) The ecological pond of this utility model is further provided with a first packing material and a second packing material in the anaerobic pond, so that the sewage on both sides of the filter layer has biological carriers.

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

[0035] Combined with the diagram Figure 1-3 As shown, this embodiment provides an ecological pond for sewage treatment, where the treated sewage is directly discharged or used for irrigation, etc.

[0036] Specifically, the ecological pond includes an anaerobic pond 1, with an inlet 10 on one side and an outlet on the other. The outlet connects to an aerobic pond 2, and a filter pond 3 is located on the other side of the aerobic pond 2, meaning the outlet of the aerobic pond 2 connects to the filter pond 3. The ecological pond also has an outlet 30, which is specifically located on the filter pond 3.

[0037] Wastewater typically enters the anaerobic tank 1 through inlet 10, then proceeds through the aerobic tank 2 and the filter tank 3 for further treatment, finally exiting through outlet 30. 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 filter tank 3 contains silt or gravel for final filtration of the wastewater.

[0038] To achieve proper sealing of the ecological ponds and improve their appearance, a cover assembly 4 is installed at the openings of the anaerobic pond 1 and the aerobic pond 2. The cover assembly 4 includes a main cover that covers the openings of the anaerobic pond 1 and the aerobic pond 2, and a ventilator pipe 41 is connected to the main cover. The main cover is a single unit that can simultaneously cover the openings of the anaerobic pond 1 and the aerobic pond 2, improving the convenience of sealing the ecological ponds.

[0039] Since gases are produced when microorganisms decompose in anaerobic tank 1 and aerobic tank 2, a vent pipe 41 is installed on the main cover for the exhaust of gases.

[0040] Furthermore, the cover assembly 4 also includes a sub-cover 43 and a filter cover 42. Specifically, observation holes are respectively opened on the main cover at positions corresponding to the openings of the anaerobic tank 1 and the aerobic tank 2, and a filter cover 42 is installed at each observation hole. A sub-cover 43 is installed on the outside of the filter cover 42. The filter cover 42 is perforated, and opening the sub-cover 43 allows observation of the internal conditions of the anaerobic tank 1 and the aerobic tank 2. At the same time, the filter cover 42 can also block external impurities, such as branches and leaves.

[0041] In this embodiment, the cover assembly 4 includes a main cover and a sub-cover 43. During normal operation of the ecological pond, if observation is required, only the sub-cover 43 needs to be opened. The main cover is only opened when the ecological pond is being maintained. The design of the cover assembly 4 improves the flexibility and convenience of observing or maintaining the ecological pond and reduces workload.

[0042] See details Figure 2 and Figure 3 As shown in the diagram, in this embodiment, the anaerobic tank 1 of the ecological pond is further provided with a filter layer 11, which is located between the inlet 10 and the outlet of the anaerobic tank. Specifically, the filter layer 11 includes two opposing filter surfaces, with the other sides serving as connecting surfaces. The filter surfaces are in contact with the wastewater, which enters the filter layer 11 through one of the filter surfaces and then flows out through the other filter surface. One of the connecting surfaces is a connecting surface 111. The anaerobic tank 1 has an opening 101, and the connecting surface 111 is positioned close to and facing the opening 101 of the anaerobic tank 1. The other connecting surfaces are close to the sides of the anaerobic tank 1. When the other connecting surfaces are close to the sides of the anaerobic tank 1, they can be pressed together or have a certain gap.

[0043] like Figure 4 As shown in the illustration, in one specific embodiment, the filter layer 11 is rectangular in shape and has a height direction, a width direction, and a thickness direction. Two opposing filter surfaces are located at both ends in the thickness direction for the inflow and outflow of wastewater. It should be noted that when the filter layer 11 is installed in the anaerobic tank 1, and the connecting surface is in close contact with the side of the anaerobic tank 1, all wastewater flowing in through the inlet 10 can be filtered through the filter layer 11.

[0044] It should also be noted that in other embodiments, the filter layer 11 may also be in other shapes, as long as the connecting surface can be close to the side of the anaerobic tank 1.

[0045] It should also be noted that in other embodiments, the number of filter layers 11 can be other, such as two or three.

[0046] In this embodiment, a filter layer 11 is also provided in the anaerobic tank 1 to filter out large particulate impurities in the sewage that are difficult to decompose, thereby cleaning up the impurities and preventing them from affecting the sewage treatment effect.

[0047] Preferably, the filter surfaces are located at both ends of the filter layer 11 in the thickness direction, thereby increasing the filter area of ​​the filter surface and improving the filtration effect of wastewater.

[0048] The filter layer 11 serves to filter impurities, but it also affects the flow rate of wastewater. To balance the filtration function of the filter layer 11 with minimizing its impact on wastewater flow rate, the thickness of the filter layer 11 is 5-50 mm. Preferably, the thickness of the filter layer 11 is 10-45 mm. More preferably, the thickness of the filter layer 11 is 15-40 mm. This ensures that the filter layer 11 provides good filtration for wastewater while minimizing its impact on wastewater treatment efficiency.

[0049] As a further improvement, the filter layer 11 has a number of filter holes 110 distributed regularly or irregularly. These filter holes 110 not only filter impurities but also contain and adsorb them. This allows impurities in the wastewater to be collected by the filter layer 11, which can then be removed for cleaning and reuse, or replaced. Once the filter layer 11 is removed, the impurities leave the anaerobic tank 1, preventing them from settling at the bottom and causing cleaning difficulties.

[0050] When the filter holes 110 are regularly distributed, the filter layer 11 is easier to process. When the filter holes 110 are irregularly distributed, each filter hole 110 is of a different size. These filter holes 110 of different sizes are randomly distributed in the filter layer 11, but the average diameter of the filter holes 110 per unit area of ​​the filter layer 11 is roughly the same, so that the filtration effect of the filter layer 11 at different positions is roughly the same, thereby improving the filtration effect of wastewater.

[0051] Furthermore, the average size of the filter pores 110 is 2-10 mm. This allows for the filtration and collection of the vast majority of impurities.

[0052] In some cases, when more than two filter layers 11 are installed, the average size of the filter pores in the filter layer 11 gradually decreases from the inlet 10 to the outlet of the anaerobic tank. This allows for layered filtration of impurities in the wastewater, improving the wastewater purification effect.

[0053] See Figure 2As shown, both the inlet 10 and the anaerobic tank outlet are located near the opening above the anaerobic tank 1. To prevent the wastewater in the lower part of the anaerobic tank 1 from having difficulty flowing, the end of the inlet 10 closest to the interior of the anaerobic tank 1 is connected to an inlet pipe, and the outlet of the inlet pipe extends to the bottom of the anaerobic tank 1. This allows the wastewater in the anaerobic tank 1 to flow from the bottom of the anaerobic tank 1 to the opening above, ensuring that all the wastewater in the anaerobic tank 1 can pass through the filter layer 11.

[0054] In a preferred embodiment, the anaerobic tank 1 is further provided with packing material. One end of the packing material is connected to one side wall of the anaerobic tank 1, and the other end is connected to the opposite side wall of the anaerobic tank 1. Specifically, the packing material includes a first packing material 12 and a second packing material 13. The first packing material 12 is located near the inlet 10, and the second packing material 13 is located near the outlet of the anaerobic tank. The first packing material 12 is typically a three-dimensional biological packing material used as a microbial carrier. The second packing material 13 is typically a biological rope packing material. The biological rope is suspended in the anaerobic tank and can spread evenly in all directions, allowing water and biofilm to fully mix and exchange, maintaining good activity and porosity variability. Moreover, it can obtain an increasingly larger specific surface area during operation and can carry out good metabolism.

[0055] In this scheme, a filter layer 11 is mainly installed in the anaerobic tank 1 to filter and remove large particulate impurities in the wastewater that are difficult to decompose. The first packing material 12 and the second packing material 13 installed in the anaerobic tank 1 provide biological carriers for the wastewater on both sides of the filter layer 11.

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.

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.
