Description

Technical Field

[0001] This invention relates to the field of wastewater treatment system technology, and specifically to a novel micro-power integrated wastewater treatment system. Background Technology

[0002] With population growth, accelerated urbanization, and the development of modern industry and urban construction, water pollution has become a serious problem. This has not only severely damaged the ecological environment but also led to water scarcity due to water quality issues, further exacerbating water resource shortages and seriously threatening drinking water safety and sustainable social and economic development. Although large-scale wastewater treatment plants, which require huge investments, can play an important role in central cities, wastewater collection and treatment are not only costly but also face significant challenges due to incomplete wastewater pipe networks and mixed sewage and rainwater discharge in many urban areas.

[0003] In vast rural areas, towns, and resorts with dispersed populations, the construction and maintenance of sewage collection networks are prohibitively expensive, even for developed countries like the United States and Europe. These sewage discharge points are often located near urban water sources. Therefore, vigorously researching and developing low-cost, environmentally friendly on-site sewage treatment technologies is of paramount importance for water pollution control in my country. Furthermore, on-site sewage treatment facilitates the reuse of treated wastewater, aligning with the requirements of a circular economy and the construction of a resource-saving society. Among the many on-site sewage treatment methods, land-based sewage treatment offers unique advantages in reducing treatment costs. Land-based sewage treatment methods mainly include five types: rapid infiltration, slow infiltration, surface runoff, wetland systems, and subsurface infiltration. Among these methods, subsurface infiltration systems do not impact the surface environment and landscape, making them suitable for urban areas and residential communities, and are widely used in the United States, Canada, and European countries.

[0004] However, traditional underground infiltration systems have multiple filtration layers. The top layer filters out a large portion of the impurities in the wastewater. As a result, the top layer is prone to clogging and needs to be frequently disassembled for cleaning and replacement, making it inconvenient to replace. Summary of the Invention

[0005] The problem to be solved by this invention is to provide a novel micro-power integrated sewage treatment system. By setting up several filter units and a mounting rack, when the top filter layer becomes clogged, the filter unit can be pulled out and replaced, ensuring the normal operation of the sewage treatment system.

[0006] The technical solution provided by the present invention to solve the above problems is as follows: a novel micro-power integrated sewage treatment system, comprising a treatment tank; wherein the treatment tank is provided with a covering layer, a primary water distribution layer, a first filter layer, a secondary water distribution layer, a second filter layer, a tertiary water distribution layer and a water collection layer from top to bottom;

[0007] The first filter layer includes several filter units and a placement rack. The placement rack is installed inside the treatment tank, and the filter units are detachably installed side by side inside the placement rack.

[0008] Preferably, the filtration unit includes a storage box and an adsorption filter media filled in the storage box. The bottom of the storage box is provided with a through hole, the diameter of which is smaller than the particle size of the adsorption filter media. The placement rack is provided with a plurality of spacers, the spacing between two spacers being matched with the width of the storage box. The side wall of the treatment tank is provided with a mating hole that mates with the storage box, and the storage box passes through the mating hole into the placement rack.

[0009] Preferably, the storage box is provided with a height marking plate, and the upper part of the adsorption filter packing is flush with the height marking plate.

[0010] Preferably, a partition is provided at one end of the storage box, and an overflow port is provided on the partition. The height of the overflow port is greater than the height of the adsorption filter material.

[0011] Preferably, an alert device is provided at the overflow outlet, and when water flows through the overflow outlet, the water flow drives the alert device to emit an alert sound.

[0012] Preferably, the reminder device includes a rotating shaft, a bell, and several blades. The rotating shaft is rotatably mounted at the overflow port, and the several blades are axially mounted at intervals on the outer circumferential surface of the rotating shaft. The bell is disposed at one end of the rotating shaft.

[0013] Preferably, the storage box is provided with an outer cover, which covers the upper part of the reminder device.

[0014] Preferably, the storage box is provided with a first mating plate and a second mating plate on both sides, and the first mating plate and the second mating plate of two adjacent storage boxes are mated together.

[0015] Preferably, the adsorption filter media is a mixture of river sand, calcium carbonate and activated carbon.

[0016] Preferably, the covering layer is hardened ground, dry land, loose soil, or green space.

[0017] Compared with the prior art, the advantages of the present invention are: by setting up several filter units and a placement rack, when the top filter layer is blocked, the filter unit can be pulled out and replaced, ensuring the normal operation of the sewage treatment system.

[0024] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] In the description of this invention, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0027] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0029] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0030] As shown in the accompanying drawings, a novel micro-power integrated sewage treatment system includes a treatment tank 1. The treatment tank 1 is characterized by having, from top to bottom, a covering layer 2, a primary water-spreading layer 3, a first filter layer, a secondary water-spreading layer 8, a second filter layer 7, a tertiary water-spreading layer 6, and a water collection layer 5.

[0031] The first filter layer includes several filter units and a placement rack 4. The placement rack 4 is installed inside the treatment tank 1, and the several filter units are detachably installed side by side inside the placement rack 4.

[0032] In this embodiment, the filtration unit includes a storage box 9 and an adsorption filter media 10 filled in the storage box 9. The bottom of the storage box 9 is provided with a through hole 11, the diameter of which is smaller than the particle size of the adsorption filter media 10. The placement rack 4 is provided with a plurality of spacers, the spacing between two spacers being matched with the width of the storage box 9. The side wall of the treatment tank 1 is provided with a mating hole that mates with the storage box 9, and the storage box 9 passes through the mating hole into the placement rack 4.

[0033] Specifically, due to the uneven distribution of impurities in wastewater, some parts of the filter layer may become clogged with impurities, resulting in reduced filtration capacity, while others may still have good filtration and adsorption capacity. Replacing the entire filter layer would easily lead to waste of the adsorption filter media. In the above solution, multiple storage boxes are set up and filled with adsorption filter media. When the filtration and adsorption capacity of the adsorption filter media in a certain storage box weakens, the storage box can be pulled out of the treatment tank for replacement, without having to replace the entire filter layer, thus improving the utilization rate of the adsorption filter media.

[0034] In this embodiment, a height marker plate 12 is provided inside the storage box 9, and the upper part of the adsorption filter packing 10 is flush with the height marker plate 12. Specifically, the adsorption filter packing is filled into the storage box so that its height is flush with the height marker plate, that is, there is still a certain distance between the adsorption filter packing and the top of the storage box.

[0035] The storage box 9 has a partition 17 at one end, and an overflow port 16 on the partition 17. The height of the overflow port 16 is greater than the height of the adsorption filter packing 10.

[0036] The overflow port 16 is equipped with an alert device. When water flows through the overflow port 16, the water flow drives the alert device to emit an alert sound. Furthermore, the alert device includes a rotating shaft 18, a bell 15, and several blades 19. The rotating shaft 18 is rotatably mounted at the overflow port 16, and the several blades 19 are axially mounted at intervals on the outer circumferential surface of the rotating shaft 18. The bell 15 is located at one end of the rotating shaft 18. Moreover, to prevent external airflow from affecting the alert device, an outer cover 20 is provided on the storage box 9, which covers the upper part of the alert device.

[0037] In the above embodiment, when the adsorption and filtration capacity of the filter media in the filter unit weakens due to the accumulation of impurities, causing blockage, the sewage filtration capacity decreases, and sewage accumulates in the storage box. After the sewage accumulates to a certain height, it will flow out from the overflow port. During this process, the blades and the rotating shaft will rotate. As the rotating shaft rotates, it will cause a bell to sound an alarm to remind the staff to replace the corresponding filter unit. It should be noted that the height of the overflow port can be designed based on calculations and experiments, which will not be elaborated here.

[0038] In order to improve the tight connection between two adjacent storage boxes and prevent sewage from leaking out between the two adjacent storage boxes, a first mating plate 13 and a second mating plate 14 are respectively provided on both sides of the storage box 9. The height of the first mating plate 13 is higher than the height of the second mating plate, and the lower end face of the first mating plate 13 and the upper end face of the second mating plate 14 of the two adjacent storage boxes 9 are tightly fitted together.

[0039] In this embodiment, the adsorption filter packing 10 is a mixture of river sand, calcium carbonate and activated carbon.

[0040] In another embodiment of the present invention, the covering layer 2 is a hardened ground, dry land, loose soil, or green space.

[0041] The above description only illustrates the preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
