Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment device with mixed energy supply. Background Technology

[0002] With the increasing emphasis on resource conservation and ecological balance, domestic wastewater needs to be treated before discharge or recycling. Existing wastewater treatment equipment mainly uses aeration, mechanical stirring, and filtration. During the wastewater flow process, pumps and other power sources are required to drive it. The continuous operation of this power equipment consumes a large amount of electricity, resulting in high energy consumption. Furthermore, power outages can interrupt the wastewater treatment process, affecting its efficiency. To ensure that domestic sewage can flow into the wastewater treatment system after being discharged underground, underground pipe networks need to be laid. Pipe network construction requires significant financial and labor costs. Moreover, in rural environments, houses are scattered, and the area is large, making pipe network laying difficult. Utility Model Content

[0003] This utility model provides a wastewater treatment device with hybrid energy supply, which aims to solve the technical problems of high energy consumption, high cost of underground pipeline laying, and unsuitability for rural areas in existing wastewater treatment systems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a wastewater treatment device with mixed energy supply, comprising: The treatment tank includes a sequentially connected facultative anaerobic zone, aerobic zone, sedimentation zone and clear water zone, as well as an inlet pipe located in the facultative anaerobic zone and an outlet pipe located in the clear water zone. The treatment tank is intended to be buried underground. An aeration assembly is provided in the aerobic zone, and the aeration assembly has an air inlet pipe extending into the ground; The packing material is located in the aerobic zone; A power pump is located in the clean water area and is connected to the inlet side of the outlet pipe; A solar power module is installed on the ground, and the solar power module has a battery that is electrically connected to the power pump.

[0005] In one possible implementation, the top of the treatment tank is provided with at least one inspection well, which is connected to one or more of the facultative anaerobic zone, the aerobic zone, the sedimentation zone, and the clear water zone.

[0006] In one possible implementation, there are multiple inspection wells, and each of the multiple inspection wells corresponds one-to-one with the facultative anaerobic zone, the aerobic zone, the sedimentation zone, and the clear water zone.

[0007] In one possible implementation, the air intake pipe extends into the ground through the maintenance well.

[0008] In one possible implementation, water passage holes are provided on the sidewalls between the anaerobic zone and the aerobic zone, and on the sidewalls between the aerobic zone and the sedimentation zone, with a grid fixedly connected inside the water passage holes.

[0009] In one possible implementation, the solar power module further includes: Photovoltaic panels; The charging controller is electrically connected to the photovoltaic panel; The inverter is electrically connected to the battery; The photovoltaic panel generates electricity to charge the battery through the charging controller.

[0010] In one possible implementation, the aeration assembly further includes a blower located on the ground-level portion of the air inlet pipe, the blower being electrically connected to the battery.

[0011] In one possible implementation, the hybrid-powered wastewater treatment device further includes a control cabinet electrically connected to the battery and used to control the start and stop of the blower and the power pump.

[0012] In one possible implementation, the filler is one of high-density polyethylene, polyethylene, polypropylene, or modified materials.

[0013] In one possible implementation, the aeration assembly includes: A coil is connected to the air inlet pipe, and the coil is located in the aerobic zone and at the bottom of the packing material; A bubble generator is located at the top of the coil and communicates with the inside of the coil, and is used to generate bubbles.

[0014] Compared with the prior art, the preliminary construction of this application includes burying the treatment tank underground, placing the aeration components in the aerobic zone, filling the packing material, and connecting the power pump to the battery. After construction is completed, the inlet pipe is connected to the sewage outlet pipe for use. During use, the sewage automatically flows into the treatment tank through gravity potential energy and passes through the facultative anaerobic zone, aerobic zone, sedimentation zone, and finally enters the clear water zone. The water in the clear water zone is relatively clear and can be reused. The treatment tank in this application uses gravity potential energy to make the sewage flow in automatically, replacing the traditional method of using a water pump to transport sewage to the sewage treatment device, saving energy. Although the clear water zone uses a power pump to extract clear water, the power pump is powered by the battery in the solar power module. The battery's power comes from solar energy, making full use of natural energy and reducing the consumption of electrical energy, achieving cost-free / low-cost operation. This application can be used directly by burying it underground. Compared with the traditional construction process of complex pipe networks, the time and labor costs in the construction process of this embodiment are significantly reduced.

The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Please refer to the following: Figure 1 The present invention provides a mixed-energy wastewater treatment device. The mixed-energy wastewater treatment device includes a treatment tank 10, an aeration assembly 20, a packing material 30, a power pump 40, and a solar power module 50. The treatment tank 10 includes a sequentially connected anaerobic zone 11, an aerobic zone 12, a sedimentation zone 13, and a clear water zone 14, as well as an inlet pipe 15 located in the anaerobic zone 11 and an outlet pipe 16 located in the clear water zone 14. The treatment tank 10 is to be buried underground. The aeration assembly 20 is located in the aerobic zone 12 and has an air inlet pipe 21 extending into the ground. The packing material 30 is located in the aerobic zone 12. The power pump 40 is located in the clear water zone 14 and is connected to the inlet side of the outlet pipe 16. The solar power module 50 is located above ground and has a battery 54 electrically connected to the power pump 40.

[0021] Specifically, the treatment tank 10 is an integrated device that can be directly buried underground. The material can be fiberglass or carbon steel, and the top surface of the treatment tank 10 is not lower than the freezing line.

[0022] The states of wastewater in the facultative anaerobic zone 11, aerobic zone 12, sedimentation zone 13, and clear water zone 14 are explained as follows: After the wastewater enters the facultative anaerobic zone 11, the facultative microorganisms in the facultative anaerobic zone 11 use nitrate instead of oxygen as an electron acceptor in the hypoxic and low-oxygen environment to decompose organic matter and produce nitrogen. After the water in the facultative anaerobic zone 11 enters the aerobic zone 12, the aeration components 20 in the aerobic zone 12 bring in external gases. The packing material 30 provides a carrier for the aerobic bacteria to attach and grow, which is conducive to the survival of the aerobic bacteria. The aerobic bacteria use the organic matter in the wastewater as a carbon and energy source, and with the participation of oxygen, they completely decompose it into harmless carbon dioxide and water. Autotrophic nitrifying bacteria oxidize the ammonia nitrogen in the wastewater in two steps (the first step is that nitrite bacteria oxidize NH4+).+ Oxidized to NO2 - In the second step, nitrifying bacteria will convert NO2 - Further oxidation to NO3 - ); After the water in the aerobic zone 12 enters the sedimentation zone 13, the water remains still here. The impurities floating in the water gradually settle to the bottom. As the water in the aerobic zone 12 gradually flows in, the water level in the sedimentation zone 13 gradually rises, and the clear water at the top of the sedimentation zone 13 gradually overflows into the clear water zone 14. The clean water in the clean water zone 14 is stored here and is drawn out by the power pump 40 when needed.

[0023] It should be noted that aerobic bacteria can include nitrosomonas, nitrifying bacteria, etc., facultative anaerobic bacteria can include denitrifying bacteria, etc., and anaerobic bacteria can include sulfate-reducing bacteria, etc.

[0024] Optionally, the power pump 40 can be a commonly used type of water pump, such as a centrifugal pump.

[0025] Compared with the prior art, the mixed-powered sewage treatment device provided in this embodiment requires less initial construction, including burying the treatment tank 10 underground, placing the aeration component 20 in the aerobic zone 12, filling the packing material 30, and connecting the power pump 40 to the battery 54. After construction is completed, the inlet pipe 15 is connected to the sewage drain pipe for use. During use, domestic sewage automatically flows into the treatment tank 10 through gravity potential energy, and sequentially passes through the facultative anaerobic zone 11, the aerobic zone 12, the sedimentation zone 13, and finally enters the clear water zone 14. The water quality in the clear water zone 14 is relatively clear and can be reused. The treatment tank 10 in this embodiment... The system utilizes gravitational potential energy to allow sewage to flow in automatically, replacing the traditional method of using water pumps to transport sewage to the sewage treatment device, thus saving energy. Although the clean water zone 14 uses a power pump 40 to extract clean water, the power pump 40 is powered by a battery 54 in the solar power module 50. The battery 54 is powered by solar energy, making full use of natural energy and reducing electrical energy consumption, achieving zero or low-cost operation. This application can be used directly by burying it underground. Compared with the traditional construction process of complex pipe networks, the time and labor costs in the construction process of this embodiment are significantly reduced.

[0026] In specific implementation, the filler 30 can be one of high-density polyethylene, polyethylene, polypropylene, or modified materials.

[0027] In some embodiments, an improved implementation of the processing pool 10 described above may employ, as follows: Figure 1 The structure shown. See also Figure 1 The top of the treatment tank 10 is provided with at least one inspection well 17, which is connected to one or more of the facultative anaerobic zone 11, aerobic zone 12, sedimentation zone 13 and clear water zone 14.

[0028] In the treatment tank 10, two adjacent zones are separated by a partition. The partition is provided with water passage holes to connect the two adjacent zones. The water passage hole between the facultative anaerobic zone 11 and the aerobic zone 12 is close to the top of the treatment tank 10, the water passage hole between the aerobic zone 12 and the sedimentation zone 13 is close to the bottom of the treatment tank 10, and the water passage between the sedimentation zone 13 and the clear water zone 14 is close to the top of the treatment tank 10.

[0029] If the treatment tank 10 does not want to be mixed with external water during normal operation, the top of the inspection well 17 can be sealed with a well cover to avoid damaging the facultative and aerobic environments inside the treatment tank 10. If it is desired to mix external rainwater and domestic sewage together for treatment, an inlet can be set on the well cover of the inspection well 17 corresponding to the facultative zone 11. External rainwater flows into the treatment tank 10 and mixes with domestic sewage for treatment, thereby increasing the sewage treatment capacity.

[0030] When maintenance is required on the treatment tank 10 (such as replacing the packing material 30, repairing the aeration component 20, or cleaning the treatment tank 10), the manhole cover of the inspection well 17 can be opened and the treatment tank 10 can be entered through the inspection well 17, which facilitates maintenance of the treatment tank 10, improves maintenance efficiency, and reduces labor intensity.

[0031] Specifically, there are multiple inspection wells 17, each corresponding to one of the facultative anaerobic zone 11, aerobic zone 12, sedimentation zone 13, and clear water zone 14. Each zone corresponds to one inspection well 17, facilitating zoned maintenance. When only one zone needs maintenance, access is only required through the corresponding inspection well 17, preventing the exposure of other zones and thus avoiding disruption to the wastewater treatment process. Furthermore, each inspection well 17 targets a single zone, resulting in a shorter access path for maintenance personnel and improved maintenance efficiency.

[0032] The aforementioned maintenance well 17 can be cylindrical or square, and the well wall is made of corrosion-resistant material to extend its service life.

[0033] In some embodiments, a specific implementation of the above-described intake pipe 21 may employ the following method: Figure 1 The structure shown. See also Figure 1 The air intake pipe 21 extends into the ground through the inspection well 17. The air intake pipe 21 is located within the inspection well 17, which communicates with the aerobic zone 12. When the top of the inspection well 17 is covered, the pipe can extend through holes in the cover, facilitating the entry of external oxygen into the aerobic zone 12. In this embodiment, the air intake pipe 21 is easy to install, eliminating the need for excavating a dedicated channel for its pre-installation. Furthermore, if the air intake pipe 21 is damaged and needs replacement, it can be easily accessed by opening the corresponding inspection well 17, improving convenience.

[0034] As an improved embodiment of the air inlet pipe 21, a seal can be provided between the air inlet pipe 21 and the manhole cover to prevent sewage from entering, and a filter device can be provided at the air inlet end of the air inlet pipe 21 to prevent dust in the air from clogging the aeration component 20.

[0035] In some embodiments, an improved implementation of the processing pool 10 described above may employ, as follows: Figure 1 The structure shown. See also Figure 1 Water passage holes are provided on the side walls between the facultative anaerobic zone 11 and the aerobic zone 12, and on the side wall between the aerobic zone 12 and the sedimentation zone 13. A grid 18 is fixedly connected inside each water passage hole. Since the aerobic zone 12 contains packing material 30, by installing grids 18 on the two side walls of the aerobic zone 12, the packing material 30 can be prevented from flowing into the facultative anaerobic zone 11 or the sedimentation zone 13 under the action of water flow, ensuring the wastewater treatment effect of the aerobic zone 12 and preventing the loss of packing material 30, which would increase operating costs.

[0036] Optionally, the grille 18 can be made of stainless steel or high-strength plastic, and the grille 18 can be fixed to the inner wall of the water passage by welding, bonding, screwing or other methods.

[0037] In some embodiments, a specific implementation of the solar power module 50 described above can adopt the following approach: Figure 1 The structure shown. See also Figure 1 The solar power module 50 also includes a photovoltaic panel 51, a charging controller 52, and an inverter 53. The charging controller 52 is electrically connected to the photovoltaic panel 51; the inverter 53 is electrically connected to the battery 54. The electrical energy generated by the photovoltaic panel 51 charges the battery 54 through the charging controller 52. The photovoltaic panel 51 generates electricity under the action of solar energy and is controlled by the charging controller 52. The charging controller 52 uses pulse width modulation or maximum power point tracking to improve the energy collection efficiency and prevent the photovoltaic panel 51 from reversing the charging to the battery 54. The inverter 53 is electrically connected to the battery 54 and can convert the DC power output from the battery 54 into AC power. The inverter 53 has overvoltage, overcurrent, and short circuit protection functions to ensure the safety of the battery 54 during the charging process. The battery 54 can be a lithium battery or a lead-acid battery, which has a large capacity energy storage function and can supply power to the power pump 40 when there is no sunlight.

[0038] Specifically, the photovoltaic panel 51 is installed on the ground by a bracket. The number and specifications of the photovoltaic panel 51 can be selected according to the actual power demand. The bracket and the photovoltaic panel 51 can be hinged by a rotating shaft, so as to facilitate the rotation and adjustment of the tilt angle of the photovoltaic panel 51 according to the angle of solar irradiation, thereby improving the light energy conversion efficiency.

[0039] In some embodiments, an improved implementation of the aeration component 20 described above may employ, as follows: Figure 1 The structure shown. See also Figure 1The aeration assembly 20 also includes a blower 22 located on the ground-level portion of the air inlet pipe 21, and the blower 22 is electrically connected to the battery 54. The battery 54 in the solar power module 50 also supplies power to the blower 22. Under the operation of the blower 22, airflow is promoted into the air inlet pipe 21, thereby allowing a large amount of oxygen to enter the aerobic zone 12 and promoting the reaction of aerobic bacteria.

[0040] Optionally, the blower 22 can be a Roots blower 22, a centrifugal blower 22, etc.

[0041] In some embodiments, an improved implementation of the above-described hybrid wastewater treatment device may employ, as follows: Figure 1 The structure shown. See also Figure 1 The mixed-power wastewater treatment device also includes a control cabinet 60, which is electrically connected to the battery 54 and used to control the start and stop of the blower 22 and the power pump 40. The control cabinet 60 is installed on the ground, and the battery 54 supplies power to the control cabinet 60 (an inverter 53 and an AC distribution box are also connected between the battery 54 and the control cabinet 60). The control cabinet 60 is equipped with a controller (e.g., PLC), relays, wiring terminals, a display screen, and operation buttons. To facilitate the control of the blower 22 and the power pump 40, a dissolved oxygen sensor can be installed in the aerobic zone 12, and a water level sensor can be installed in the clear water zone 14. The controller receives signals from the above sensors and controls the start and stop of the blower 22 and the power pump 40 according to preset levels or manual operation. It can also adjust the air volume and the speed of the power pump 40. The display screen can display the operating status of the blower 22 and the power pump 40, the detection parameters of each sensor, and the remaining power of the battery 54 in real time.

[0042] This embodiment uses a control cabinet 60 to facilitate centralized control of the fan 22 and the power pump 40, replacing manual control, achieving automation, improving control accuracy, and reducing operational difficulty.

[0043] It should be noted that in the embodiment with control cabinet 60, the current transmission path is approximately as follows: photovoltaic panel 51, charging controller 52, battery 54, inverter 53, AC distribution box, control cabinet 60.

[0044] In some embodiments, a specific implementation of the aeration component 20 described above may employ, as follows: Figure 1 The structure shown. See also Figure 1The aeration assembly 20 includes a coil 23 and a bubble generator 24. The coil 23 is connected to the air inlet pipe 21 and is located in the aerobic zone 12 at the bottom of the packing 30. The bubble generator 24 is located at the top of the coil 23 and is connected to the inside of the coil 23 to generate bubbles. The coil 23 is spiral or serpentine and conforms to the cross-sectional shape of the aerobic zone 12, ensuring that the bubble generator 24 is evenly distributed at the bottom of the aerobic zone 12. One end of the coil 23 is connected to the air inlet pipe 21, and a sealing measure can be used at the joint. When gas enters the coil 23 through the air inlet pipe 21, it is converted into small bubbles by the bubble generator 24 and enters the aerobic zone 12, ensuring that the bubbles can fully pass through the gaps in the packing 30, improving the uniformity of aeration and ensuring the efficiency of the aerobic reaction.

[0045] It should be noted that the bubble generator 24 includes a conical base (hollow) fixed to the coil 23 and an elastic diaphragm covering the top of the base. When the gas passes through the elastic diaphragm, the diaphragm bulges and the aeration holes open under the action of gas pressure because the elastic diaphragm is uniformly provided with micron-sized aeration holes, which can disperse the gas into small bubbles.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
