DETAILED DESCRIPTION

[0028] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of this utility model, "a plurality" means more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Rural areas lack professional operators and maintenance personnel for sewage treatment equipment, and are unable to afford the high operating costs, resulting in relatively backward sewage treatment technology and ineffective sewage treatment. This is because rural domestic sewage treatment is scattered, numerous, small-scale, complex, and difficult to predict. Currently, a mature investment return mechanism has not yet been established, and social capital participation is not very enthusiastic. In addition, the farmer payment system for sewage treatment is still in the exploratory stage. Funding for rural sewage treatment is largely dependent on financial investment at all levels, especially at the county level. As a result, rural areas are more sensitive to sewage treatment costs.

[0033] Because rural domestic sewage treatment is scattered and small-scale, the amount of sewage fluctuates greatly. During certain periods of time, no sewage enters the sewage treatment facilities. If no measures are taken to regulate this, the microorganisms used in sewage treatment will die, resulting in poor treatment results when sewage levels reach peak levels again. In this case, it is necessary to re-cultivate microorganisms and increase their number to ensure that sewage treatment meets the standards.

[0034] Reference Figure 1 As shown, a clean power biofilm purification tank according to an embodiment of the present invention includes a tank body 100 , a linkage shaft 200 , a plurality of filler turntables 300 , a fan assembly 400 , a switching mechanism 500 , a motor assembly 600 and a photovoltaic assembly 700 .

[0035] The tank body 100 has a water inlet and a water outlet. The sewage is introduced into the tank body 100 through the water inlet for biological treatment, including anaerobic, anoxic and aerobic reactions, to achieve the removal of COD, BOD, ammonia nitrogen and SS in the sewage. The treated sewage is then discharged through the water outlet. Preferably, the water outlet is set at a height higher than the water inlet, and the upper clear liquid is discharged by overflow. It should be understood that in order to ensure that there is enough oxygen in the tank body 100 for the microorganisms to carry out aerobic reactions, the sewage introduced into the tank body 100 should not fill the internal space of the tank body 100, and a certain amount of air should be retained inside the tank body 100.

[0036] The linkage shaft 200 is horizontally passed through the tank body 100, and the linkage shaft 200 is provided with a plurality of stuffing turntables 300, and the plurality of stuffing turntables 300 are distributed at intervals along the axial direction of the linkage shaft 200. Therefore, the stuffing turntables 300 can rotate in the tank body 100 only by driving the linkage shaft 200 to rotate. Because the linkage shaft 200 is horizontally passed through the tank body 100, and there is space for air in the upper part of the tank body 100, when the stuffing turntable 300 rotates, the microorganisms attached to the stuffing turntable 300 can periodically come into contact with the air. In addition, the rotating stuffing turntable 300 can also stir the sewage in the tank body 100, so that the organic matter in the sewage can fully come into contact with the stuffing turntable 300, that is, the sewage can fully come into contact with the microorganisms, thereby improving the treatment effect.

[0037] Within tank 100, an anoxic environment is created within the wastewater. The submerged packing disc 300 undergoes anoxic and / or anaerobic reactions, while the packing disc 300 above the wastewater surface, exposed to air, creates an aerobic environment where microorganisms undergo aerobic reactions. As the linkage shaft 200 rotates, the packing disc 300 continuously shifts the position of the microorganisms, periodically alternating between anaerobic, anoxic, and aerobic reactions within tank 100, effectively breaking down pollutants and purifying the water.

[0038] The fan assembly 400 is in driving connection with the first end of the linkage shaft 200. The fan assembly 400 is driven by wind. A switching mechanism 500 is also provided between the fan assembly 400 and the linkage shaft 200. The switching mechanism 500 is used to connect or disconnect the transmission between the fan assembly 400 and the linkage shaft 200. The fan assembly 400 uses wind power to generate kinetic energy, which is transmitted to the linkage shaft 200 to drive the linkage shaft 200 to rotate. As a clean energy source, wind power can reduce energy expenses for sewage treatment and lower operating costs. During most periods of time, wind power can be used to drive the linkage shaft 200 to rotate.

[0039] Of course, taking into account the situation of no wind or insufficient wind, the motor assembly 600 and the photovoltaic assembly 700 are still provided. The motor assembly 600 is connected to the second end of the linkage shaft 200 in a transmission manner. The motor assembly 600 is also connected to the photovoltaic assembly 700, which provides energy for the motor assembly 600. The photovoltaic assembly 700 converts solar energy into electrical energy, which is used to drive the motor assembly 600 to rotate, and can drive the linkage shaft 200 to rotate. Similarly, solar energy is also a clean energy source that can reduce the energy expenditure of sewage treatment and reduce operating costs. The motor assembly 600 serves as an auxiliary drive for the fan assembly 400. Only when the fan assembly 400 cannot work, the power source is switched to the motor assembly 600. When the motor assembly 600 is working, in order to prevent the fan assembly 400 from being driven in reverse by the motor assembly 600 and doing useless work, the transmission of the fan assembly 400 and the linkage shaft 200 can be disconnected by the switching mechanism 500. When the fan assembly 400 regains the ability to drive the linkage shaft 200 to rotate, the motor assembly 600 stops working, and the switching mechanism 500 connects the fan assembly 400 to the linkage shaft 200 again.

[0040] It should be understood that the switching mechanism 500 is a relatively mature application. For example, a clutch or a movable coupling can be used. Alternatively, a simpler method can be used, where a gear transmission is used between the fan assembly 400 and the linkage shaft 200. By controlling the gear to move on the transmission key, the meshing relationship between the gear sets can be adjusted. For example, when the gear set is in a meshing state, the fan assembly 400 and the linkage shaft 200 are in a transmission connection; when the gear set is in a non-meshing state, the fan assembly 400 and the linkage shaft 200 are disconnected.

[0041] In the above examples, COD (Chemical Oxygen Demand) refers to chemical oxygen demand, which measures the amount of organic matter in water that can be oxidized by chemical oxidants. The COD value reflects the degree of organic contamination in the water. A higher COD value indicates a higher amount of organic matter in the water and a more severe contamination.

[0042] BOD (Biochemical Oxygen Demand) refers to biochemical oxygen demand or biochemical oxygen consumption, and is an important indicator for measuring the degree of organic pollution in water. The higher the BOD value, the more organic matter there is in the water, and the worse the water quality.

[0043] SS (Suspended Solids) refers to the solid matter in suspended state in sewage.

[0044] Reference Figure 2As shown, it can be understood that the fan assembly 400 includes a first transmission shaft 410 and a plurality of blades 420, the first transmission shaft 410 is horizontally arranged, the plurality of blades 420 are distributed around the circumference of the first transmission shaft 410 and are connected to the first transmission shaft 410, and the first transmission shaft 410 is transmission-connected to the linkage shaft 200.

[0045] Specifically, a gear set can be provided between the first transmission shaft 410 and the linkage shaft 200 for transmission, and the transmission ratio can be changed by the gear set. The gear set can be a speed reduction mechanism. Generally, the speed of the linkage shaft 200 is lower than the speed of the first transmission shaft 410.

[0046] For example, refer to Figure 2 or Figure 3 As shown, a second transmission shaft 430 is provided between the first transmission shaft 410 and the linkage shaft 200 , a bevel gear set is provided between the first transmission shaft 410 and the second transmission shaft 430 , and another bevel gear set is provided between the second transmission shaft 430 and the linkage shaft 200 .

[0047] The linkage shaft 200 and the tank body 100 are arranged at a low position to reduce the power consumption required for sewage to enter the tank body 100. The higher the tank body 100, the more gravitational potential energy the sewage needs to overcome. It is understandable that at a high position, there are no buildings or other obstacles blocking it, the wind energy is relatively greater, and it is easier to capture wind power. When the linkage shaft 200 is arranged horizontally, the linkage shaft 200 is connected to the second transmission shaft 430 through a bevel gear set, and the second transmission shaft 430 can be arranged vertically to increase the height of the other end of the second transmission shaft 430. The second transmission shaft 430 is connected to the first transmission shaft 410 through a bevel gear set. The first transmission shaft 410 can continue to be arranged in a horizontal state to increase the windward area of the blades 420 as much as possible and improve the efficiency of converting wind energy into mechanical energy.

[0048] Reference Figure 3 As shown, it can be understood that the photovoltaic assembly 700 includes a photovoltaic panel 710 and an energy storage mechanism 720 , the photovoltaic panel 710 is electrically connected to the energy storage mechanism 720 , and the energy storage mechanism 720 is electrically connected to the motor assembly 600 .

[0049] The photovoltaic assembly 700 converts solar energy into electrical energy, which powers the motor assembly 600. The motor assembly 600 then generates power for the linkage shaft 200, driving the linkage shaft 200 to rotate. It should be understood that the motor assembly 600 is only activated when the fan assembly 400 is insufficiently powered to drive the linkage shaft 200. When the motor assembly 600 is operating, the switching mechanism 500 disconnects the transmission between the fan assembly 400 and the linkage shaft 200.

[0050] Furthermore, a power generation assembly 800 is provided, the first transmission shaft 410 is in driving connection with the power generation assembly 800, and the power generation assembly 800 is electrically connected to the energy storage mechanism 720. When the wind turbine assembly 400 is sufficiently powerful, the power generation assembly 800 can also be used to convert wind energy into electrical energy and store it in the energy storage mechanism 720.

[0051] When the wind turbine assembly 400 is able to normally drive the linkage shaft 200 to rotate, the motor assembly 600 is not operating. At the same time, the photovoltaic assembly 700 can still convert solar energy into electrical energy. The energy storage mechanism 720 is provided to store this electrical energy and provide it to the motor assembly 600 when appropriate. The energy storage mechanism 720 can be a battery pack. The electricity generated by the photovoltaic assembly 700 charges the battery pack, and the battery pack, in combination with the inverter, can provide the battery pack's electrical energy to the motor assembly 600.

[0052] It is understandable that a control component 900 is provided, the control component 900 is electrically connected to the motor component 600 , and the control component 900 is electrically connected to the switching mechanism 500 , and the control component 900 is used to regulate the working states of the motor component 600 and the switching mechanism 500 .

[0053] The control component 900 is used to write a program to complete the transmission switching between the motor component 600 and the fan component 400. For example, it can determine whether the fan component 400 can drive the linkage shaft 200 to rotate based on the wind speed. If the fan component 400 cannot drive the linkage shaft 200 to rotate, the control is promptly switched to the motor component 600 for driving. Preferably, the control component 900 can directly obtain the speed or torque of the fan component 400. Using the speed or torque of the fan component 400 can more accurately determine whether the fan component 400 can drive the linkage shaft 200 to rotate. Another important function of the control component 900 is to control the working state of the switching mechanism 500 according to the operating state of the motor component 600. Specifically, when the motor component 600 is working, the switching mechanism 500 must disconnect the transmission between the fan component 400 and the linkage shaft 200 to prevent the motor component 600 from driving the linkage shaft 200 to rotate and reversely drive the fan component 400 to rotate, thereby doing useless work.

[0054] Reference Figure 4 As shown, it can be understood that the linkage shaft 200 is provided with a plurality of strip fillers 310, one end of the strip filler 310 is connected to the linkage shaft 200, and the other end extends outward. Several strip fillers 310 are grouped together and distributed around the circumference of the linkage shaft 200 to form a filler turntable 300.

[0055] Compared with ordinary round fillers, the gaps between the strip fillers 310 are larger. When the strip fillers 310 rotate with the linkage shaft 200, sewage can more easily move between the strip fillers 310, promoting the contact between sewage and microorganisms on the strip fillers 310 and improving reaction efficiency.

[0056] Reference Figure 5 As shown, it can be understood that each strip filler 310 includes a main branch 311 and multiple branches 312, one end of the main branch 311 is connected to the linkage shaft 200, and the other end extends outward, and the multiple branches 312 are all connected to the main branch 311, and the multiple branches 312 are cross-distributed along the axial direction of the main branch 311.

[0057] A plurality of branches 312 are distributed on the main branch 311, thereby increasing the surface area for microorganisms to attach and increasing the amount of microorganisms.

[0058] It is understandable that at least one ventilation hole 110 is provided on the upper portion of the tank body 100 .

[0059] Preferably, two ventilation holes 110 are provided, wherein one ventilation hole 110 is used for air intake and the other ventilation hole 110 is used for air discharge, which helps external air flow in the tank body 100 and brings oxygen into the tank body 100 to help microorganisms perform aerobic reactions.

[0060] It is understandable that the tank body 100 is used to carry sewage. In order to ensure that there is enough oxygen in the tank body 100 for microorganisms to perform aerobic reactions, the liquid level of the sewage is preferably between 1 / 2 and 2 / 3 of the height of the tank body 100.

[0061] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
