Description

Technical Field

[0001] The utility model relates to the field of household sewage treatment equipment, in particular to household sewage treatment equipment. Background Art

[0002] As for domestic sewage, it contains a lot of organic matter. If these organic matter are discharged directly into the ditch environment without treatment, the microorganisms in the ditch will multiply in large numbers, which will cause the phytoplankton in the ditch to multiply in large numbers, and then lead to nutrient enrichment in the ditch, which will damage the ecological environment of the local water system in the ditch. At present, the treatment method of domestic sewage is mostly through sewage treatment plants. However, it is inconvenient to lay sewage pipelines in rural communities. Centralizing sewage to sewage treatment plants for treatment will waste a lot of material and financial resources, and there are many uncertain factors, which does not meet the needs of long-term sustainable development. At present, most of the methods of treating domestic sewage are direct dumping, which cannot achieve effective sewage treatment, thereby causing pollution to the local environment and groundwater system, which is not conducive to the subsequent exploitation and use of water resources.

[0003] Based on the above problems, it is necessary to set up a household sewage treatment equipment that can treat domestic sewage so that the treated sewage can be used for irrigation needs such as watering flowers. Even if the treated sewage is discharged, it will not have a major impact on the local water system, and thus will not cause environmental pollution problems. Utility Model Content

[0004] The purpose of this utility model is to provide a household sewage treatment device, which can process domestic sewage so that the discharged domestic sewage meets the treatment requirements after treatment, thereby avoiding causing local environmental pollution and ensuring the development requirements of sustainable development.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] A household sewage treatment device comprises a shell, in which an anaerobic sedimentation zone, an aeration zone, a sedimentation zone, and an adsorption zone are arranged. The anaerobic sedimentation zone and the aeration zone are separated by a first partition plate, the aeration zone and the sedimentation zone are separated by a second partition plate, and the sedimentation zone and the adsorption zone are separated by a third partition plate. Connecting pipes are provided on the first partition plate, the second partition plate, and the third partition plate. When sewage enters the shell, it passes through the anaerobic sedimentation zone, the aeration zone, the sedimentation zone, and the adsorption zone in sequence under the connection of the connecting pipes to be purified.

[0007] The communicating pipe includes a first communicating pipe, a second communicating pipe, and a third communicating pipe. The first communicating pipe is arranged at the second partition plate position; the second communicating pipe is arranged at the second partition plate position; and the third communicating pipe is arranged at the third partition plate position.

[0008] The anaerobic precipitation zone is connected to a water inlet pipe, which is a T-shaped elbow. The lower end opening of the T-shaped elbow is arranged near the bottom end of the anaerobic precipitation zone; the water inlet position of the water inlet pipe is higher than the height position of the shell.

[0009] An aeration fan assembly is provided in the aeration zone, and the sewage in the aeration zone is aerated by the aeration fan assembly.

[0010] The first communicating pipe is an L-shaped elbow, and the communication between the anaerobic precipitation zone and the aeration zone is achieved through the L-shaped elbow.

[0011] The second communicating pipe is a T-shaped elbow, and the lower end opening of the T-shaped elbow is arranged close to the bottom end of the sedimentation zone.

[0012] The third communicating pipe is an L-shaped elbow, and the communication between the precipitation zone and the adsorption zone is achieved through the L-shaped elbow.

[0013] Adsorption material is provided in the adsorption area, and the pollutants in the adsorption area are adsorbed and cleaned by the adsorption material.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] During the installation of this device, the task of cleaning sewage is accomplished by setting up an anaerobic sedimentation zone, an aeration zone, a sedimentation zone, and an adsorption zone. The anaerobic sedimentation zone is designed for the growth conditions of anaerobic bacteria. Anaerobic bacteria can decompose organic matter in the absence of oxygen, so the mechanism by which this pool treats sewage and removes pollutants primarily relies on the action of anaerobic bacteria. The aeration zone is a process that forces oxygen from the air to transfer into the liquid. Its purpose is to obtain sufficient dissolved oxygen, thereby ensuring that the microorganisms in the pool have sufficient dissolved oxygen to oxidize and decompose organic matter in the sewage. The sedimentation zone and adsorption zone are respectively capable of precipitating and adsorbing sediment in the sewage, thereby achieving the task of cleaning sewage.

[0020] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0021] For household sewage treatment, it is necessary to consider the convenience of sewage treatment and the cost of sewage treatment. Therefore, it cannot be the same as the mechanized sewage treatment method. It is necessary to consider household problems, so the following structure is set:

[0022] A household sewage treatment device includes a shell 1, in which an anaerobic sedimentation zone 2, an aeration zone 3, a sedimentation zone 4, and an adsorption zone 5 are arranged. The anaerobic sedimentation zone 2 and the aeration zone 3 are separated by a first partition plate 6, the aeration zone 3 and the sedimentation zone 4 are separated by a second partition plate 7, and the sedimentation zone 4 and the adsorption zone 5 are separated by a third partition plate 8; connecting pipes are provided on the first partition plate 6, the second partition plate 7, and the third partition plate 8. When sewage enters the shell 1, it passes through the anaerobic sedimentation zone 2, the aeration zone 3, the sedimentation zone 4, and the adsorption zone 5 in sequence under the connection of the connecting pipes to be purified.

[0023] For the above structural setting, the following explanation is given:

[0024] Anaerobic Sedimentation Zone 2: After the shell 1 is fastened, the anaerobic sedimentation zone 2 forms a sealed environment with a relatively low oxygen content, creating conditions for the growth and reproduction of anaerobic bacteria within the zone. Anaerobic bacteria can decompose organic matter in the absence of oxygen, so the mechanism by which this tank treats wastewater and removes pollutants primarily relies on the action of anaerobic bacteria. Through anaerobic reactions, some difficult-to-degrade organic matter in the wastewater is converted into more easily degradable substances. These difficult-to-degrade substances are then precipitated over a long period of time and reach the bottom layer of the anaerobic sedimentation zone 2, achieving initial wastewater treatment.

[0025] Aeration zone 3: When setting up the aeration zone 3, an aeration fan assembly is provided in the aeration zone 3, and the sewage in the aeration zone 3 is aerated by the aeration fan assembly. Here, air is pumped into the sewage in the aeration zone 3 by the aeration air assembly, so that the oxygen content in the sewage in the aeration zone 3 is enhanced, and the dissolved oxygen content in the water is increased. In this part, aerobic microorganisms can obtain more sufficient physiological activity, so that the microorganisms can quickly oxidize and decompose organic matter, and then carry out secondary decomposition of organic matter that anaerobic bacteria cannot decompose. At the same time, during the operation of injecting air into the sewage in the aeration zone 3, the sewage will be in a state of motion in the aeration zone 3, so that more organic matter can be fully decomposed by microorganisms, and sludge and other substances produced by oxidative decomposition can be prevented from settling in the aeration zone 3, so as to ensure that the subsequent sludge can be effectively precipitated in the sedimentation zone 4.

[0026] Sedimentation zone 4: After the sewage passes through the aeration zone 3 and enters the sedimentation zone 4, it is left to stand in the sedimentation zone 4 so that the microorganisms and sludge flocculation and sedimentation occur. At this time, the sewage has been purified to a relatively clean level.

[0027] Adsorption Zone 5: When configuring the adsorption zone 5, an adsorption material 12 is disposed within the adsorption zone 5. This adsorption material 12 adsorbs and removes pollutants within the adsorption zone 5. The adsorption zone 5 is filled with adsorption material 12, namely, an inorganic active filter material. This inorganic active filter material has a large surface area, numerous active groups, high adsorption activity, and strong adsorption capacity, effectively adsorbing harmful substances in wastewater. The inorganic active filter material is a mixture of various particles with a high porosity, capable of filtering and retaining most suspended solids, complementing adsorption and enabling the filter layer to function as both an adsorption and filtration layer.

[0028] After the sewage has undergone the above treatment, the purified water can be used for applications such as watering flowers.

[0029] The specific structural settings of the connecting pipes are as follows:

[0030] The anaerobic precipitation zone 2 is connected to a water inlet pipe, which is a T-shaped bend, and the lower end opening of the T-shaped bend is arranged close to the bottom end position of the anaerobic precipitation zone 2; the water inlet position of the water inlet pipe is higher than the height position of the shell 1. First, the water inlet position of the water inlet pipe is arranged higher than the height position of the shell 1 to ensure that the liquid flow in this device can be achieved only by direct current, and the liquid flow requirements can be met without the need to set up a suction pump body. Secondly, the water inlet pipe is a T-shaped bend, and the lower end opening of the T-shaped bend is arranged close to the bottom end position of the anaerobic precipitation zone 2, so that the sewage can first enter the lower position of the anaerobic precipitation zone 2. This part has the least oxygen content and can better enable anaerobic bacteria to decompose and transform some organic matter, thereby ensuring the effectiveness of sewage treatment.

[0031] The communicating pipes include a first communicating pipe 9 , a second communicating pipe 10 , and a third communicating pipe 11 . The first communicating pipe 9 is arranged at the position of the second partition plate 7 ; the second communicating pipe 10 is arranged at the position of the second partition plate 7 ; and the third communicating pipe 11 is arranged at the position of the third partition plate 8 .

[0032] The first connecting pipe 9 is an L-shaped elbow, which realizes the connection between the anaerobic precipitation area 2 and the aeration area 3 to avoid the decomposed sediment in the aeration area 3 from flowing back into the anaerobic precipitation area 2 due to the flow of liquid inside the aeration area 3, causing more sediment to be generated in the anaerobic precipitation area 2, which is not conducive to the user's subsequent cleaning of the anaerobic precipitation area 2.

[0033] The second connecting pipe 10 is a T-shaped elbow, and the lower end opening of the T-shaped elbow is arranged near the bottom end of the sedimentation area 4; that is, it ensures that after the sewage in the aeration area 3 is transported to the inside of the sedimentation area 4, it can be directly settled at the bottom of the sedimentation area 4, avoiding contamination of the clean sewage in the upper layer of the sedimentation area 4, thereby causing secondary pollution to the sewage in the sedimentation area 4.

[0034] The third communication pipe 11 is an L-shaped elbow, and the communication between the precipitation zone 4 and the adsorption zone 5 is achieved through the L-shaped elbow.

[0035] For the water outlet pipe in the adsorption zone 5 , more adsorption materials 12 in the adsorption zone 5 should be covered as much as possible to ensure a better sewage treatment effect.

[0036] Therefore, the setting of a household sewage treatment equipment can realize the treatment of domestic sewage, so that the treated sewage can be used for irrigation needs such as watering flowers. Even if the treated sewage is discharged, it will not cause a major impact on the local water system, and thus will not cause environmental pollution problems.
