[0040] Reference Figures 1 to 3The photovoltaic micro-powered aeration integrated device suitable for rural domestic sewage treatment of the first aspect embodiment of the present application is applied to rural domestic sewage treatment. The photovoltaic micro-powered aeration integrated device suitable for rural domestic sewage treatment includes a pretreatment tank 100, an aeration component 200 and a photovoltaic panel assembly 300.

[0041] The pretreatment tank 100 is used to receive domestic sewage; the aeration component 200 is used to aerate the sewage in the pretreatment tank 100; and the photovoltaic panel assembly 300 is used to provide direct current to the aeration component 200 so that the aeration component 200 can continue to work when the photovoltaic panel assembly 300 is powered.

[0042] It is understandable that, considering the large difference in water consumption between day and night in rural areas, the pretreatment tank 100 is used to receive domestic sewage at night, and the photovoltaic panel assembly 300 is used to provide direct current to the aeration component 200 during the day to aerate the pretreatment tank 100. This not only realizes the automated sewage treatment cycle, but also eliminates the need for components such as batteries and inverters, thereby meeting the economical requirements of rural sewage treatment.

[0043] In some embodiments of the present application, the aeration component 200 includes a DC aeration pump, which directly receives the electric energy provided by the photovoltaic panel assembly 300 and is used to aerate the sewage in the pretreatment tank 100. It can be understood that the DC aeration pump is electrically connected to the photovoltaic panel assembly 300 and can directly receive the DC power input from the photovoltaic panel assembly 300 to work, thereby eliminating the setting of components such as batteries and inverters, and meeting the economic and practical requirements of rural sewage treatment without affecting the aeration effect of the pretreatment tank 100.

[0044] In some embodiments, the DC aeration pump uses an electromagnetic oscillation pump to meet usage requirements and ensure processing efficiency.

[0045] In some embodiments of the present application, the aeration component 200 includes an air lift reflux assembly, a packing area 110 is provided in the pretreatment tank 100, and the DC aeration pump aerates the packing area 110 through the air lift reflux assembly. It can be understood that the DC aeration pump can aerate the appropriate position of the pretreatment tank 100 through the air lift reflux assembly, thereby ensuring the overall aeration efficiency and quality of the pretreatment tank 100, allowing aerobic microorganisms to fully contact organic matter in the sewage, thereby achieving the purpose of improving oxygen utilization and reducing hydraulic retention time.

[0046] In some embodiments, one end of the air stripping reflux pipe 400 extends into a preset position in the pretreatment tank 100 , so that the preset position of the pretreatment tank 100 can be aerated more evenly.

[0047] In some embodiments of the present application, the air lift reflux assembly includes an air lift reflux pipe 400, the air lift reflux pipe 400 is arranged through the filling area 110, the DC aeration pump is arranged in the air lift reflux pipe 400, and the air release point of the DC aeration pump is located within the range of the filling area 110. It can be understood that the upper end of the air lift reflux pipe 400 is located above the filling area 110, and the lower end of the air lift reflux pipe 400 is located below the filling area 110. The DC aeration pump is arranged in the air lift reflux pipe 400 to achieve aeration, so that the air can rise and pass through the filling area 110 through the air lift reflux pipe, wherein the air release point of the DC aeration pump is located in the filling area 110, which can release the air in the filling, and will drive the water flow to filter the suspended matter in the water flow in the filling area 110 when it rises, and the water quality is continuously circulated and becomes clear, and the DC aeration pump receives the electric energy provided by the photovoltaic panel assembly 300 to better meet the stability and frequency of air release.

[0048] In some embodiments, on the basis that the photovoltaic panel assembly 300 can make the DC explosion pump work normally, in order to ensure the stable air release of the DC explosion pump, the air stripping return assembly includes an air pipe 410, and the air pipe 410 is connected to one end of the air stripping return pipe 400, and the other end of the air stripping return pipe 400 passes through the filling area 110 and is located at the relative bottom of the pretreatment tank 100, so that there is a preset distance between the air release point of the DC aeration pump and the other end of the air stripping return pipe 400. The air required for aeration of the DC explosion pump is provided through the air pipe 410, and the air release point of the DC aeration pump and the other end of the air stripping return pipe 400 are designed to have a preset distance, thereby ensuring sufficient air flow.

[0049] In some embodiments of the present application, in order to achieve precise aeration control of sewage treatment and to make full use of solar energy to improve the aeration efficiency per unit time, this photovoltaic micro-power aeration integrated device suitable for rural domestic sewage treatment also includes a driving component and an information monitoring unit. The driving component is used to drive the other end of the gas lift return pipe 400 to move in a three-dimensional direction. The information monitoring unit is arranged on the gas lift return pipe 400 and is used to obtain sewage information in the pretreatment tank 100. The driving component can realize negative feedback control of the other end of the gas lift return pipe 400 according to the information of the information monitoring unit, and the DC aeration pump can adjust the working state according to the information of the information monitoring unit.

[0050] It is understandable that the air lift return pipe 400 is driven by the driving component to move in the three-dimensional directions of horizontal, longitudinal and vertical directions in the pretreatment tank 100, so that the other end of the air lift return pipe 400 can reach various positions in the pretreatment tank 100, and the sewage situation in the pretreatment tank 100 is detected by setting an information monitoring unit, so that the other end of the air lift return pipe 400 can reach the place where aeration is most needed to achieve aeration, and ensure that the aeration efficiency can be maintained when using direct current, so as to fully utilize the conversion of solar energy into electrical energy within a limited time. The DC aeration pump can also adaptively adjust its own working parameters such as aeration power and different power duration according to the sewage situation in the pretreatment tank 100, so that the sewage in the pretreatment tank 100 can be treated in time, so that the DC aeration pump can also have a good aeration effect after receiving the electrical energy provided by the photovoltaic panel assembly 300.

[0051] In some embodiments, the information monitoring unit includes but is not limited to sludge concentration, dissolved oxygen, ammonia nitrogen monitoring sensors, etc., and the type and number of sensors set can be adaptively adjusted according to actual usage needs in rural areas.

[0052] In some embodiments, the driving component may be a commonly used driving component capable of multi-degree-of-freedom mechanical motion, such as a robotic arm, a three-way screw driving component, a slide module, etc., which will not be described in detail herein.

[0053] In some embodiments of the present application, the clean water tank is used to collect treated clean water, which can not only be directly used by rural users during the day, but also can be used by rural users at night by collecting a sufficient amount.

[0054] In some embodiments, the filler area 110 combines the dual effects of plant oxygen supply and enhanced natural reoxygenation to achieve efficient removal of organic matter.

[0055] In some embodiments of the present application, a control device, a light detection unit and a clean water tank are also included. The clean water tank is used to collect the effluent after being treated by the pretreatment tank 100. The control device is configured to control the working parameter information of the aeration component 200 according to the water volume information in the clean water tank and / or the detection information of the light detection unit, so that the water volume in the clean water tank can be within a preset range. It can be understood that the control device is used to monitor and control the entire system in real time, so that rural domestic sewage can achieve organic matter removal after combining with photovoltaic micro-power aeration, and the integrated device can meet the needs of rural domestic sewage treatment. In some embodiments, liquid level control systems are respectively set in the clean water tank and the pretreatment tank 100, so that more precise control can be achieved in conjunction with the control device.

[0056] In some embodiments of the present application, the method of controlling the aeration component 200 can be determined according to different light intensities, so that the aeration component 200 can make full use of solar energy to achieve sufficient aeration per unit time, ensuring that the amount of water in the clean water tank can be quickly maintained within a suitable range. In this regard, the control device is configured to control the working parameter information of the aeration component 200 according to the detection information of the light detection unit, including:

[0057] A plurality of solar illumination intervals are defined by the control device, and different control modes for the aeration component 200 are set according to different solar illumination intervals;

[0058] The control device receives the real-time solar illumination detected by the light detection unit, and determines the corresponding control mode according to the real-time solar illumination;

[0059] The control device adjusts the working parameter information of the aeration component 200 according to the corresponding control mode, so that the aeration component 200 is in a preset working state, and the water volume in the clean water tank can be within a preset range.

[0060] It can be understood that the aeration component 200 of the present application directly receives direct current from the photovoltaic panel assembly 300, and therefore only works for aeration when there is sunlight. Based on this, the working frequency of the aeration component 200 is adjusted according to different light intensities, so that the aeration component 200 works normally at normal light intensity, and the working frequency of the aeration component 200 is increased as much as possible at lower light intensity, so as to achieve sufficient aeration per unit time, and ensure that the water volume in the clean water tank can be quickly maintained within a suitable range, so as to meet the condition that water can still be supplied normally for a certain period of time when there is no sunlight in the future.

[0061] On the basis of determining the method of controlling the aeration component 200 according to different light intensities, it is also necessary to control the working parameter information of the aeration component 200 according to the water volume information in the clean water tank. In some embodiments of the present application, the control device is configured to control the working parameter information of the aeration component 200 according to the water volume information in the clean water tank. The method includes:

[0062] A liquid level detection unit is provided in the clean water tank;

[0063] The control device determines the corresponding control mode according to the information of the liquid level detection unit;

[0064] The control device adjusts the working parameter information of the aeration component 200 according to the corresponding control mode, so that the aeration component 200 is in a preset working state, and the water volume in the clean water tank can be within a preset range.

[0065] It is understandable that the control device can combine the data of the liquid level detection unit, the light detection unit and the information monitoring unit at the same time, so as to control the working parameter information of the aeration component 200 so that the water volume in the clean water tank can be dynamically within a preset range.

[0066] In some embodiments, considering the large amount of domestic water consumption in rural areas during the day, in order to prevent the water in the clean water tank from being quickly used up, the specific water consumption is monitored in real time through the setting of the liquid level detection unit. When the water volume in the clean water tank is lower than the preset interval during the day, the control device adjusts the working parameter information of the aeration component 200 to increase the frequency of the aeration component 200, and / or cooperates with the driving component to drive the air lift return pipe 400 to move, thereby improving the aeration efficiency, until the water volume in the clean water tank is again within the preset interval, so as to meet the use needs at night. Similarly, when the water volume in the clean water tank is higher than the preset interval during the day, the control device adjusts the working parameter information of the aeration component 200 to reduce the frequency of the aeration component 200, and / or cooperates with the driving component to drive the air lift return pipe 400 to move, thereby reducing the aeration efficiency, until the water volume in the clean water tank is restored to the preset interval again.

[0067] In some embodiments, a time unit is also included. The control device determines the corresponding control mode of the aeration component 200 according to the time information provided by the time unit to ensure that the water level in the clean water tank is within a preset range as much as possible before sunset to meet the needs of night use.

[0068] In some embodiments of the present application, the control device is used to control the sewage to stay in the pretreatment tank 100 for at least 24 hours and in the clean water tank for at least 2 hours. It is understandable that the pretreatment tank 100 is designed to stay for 24 hours, which is used to simultaneously achieve the functions of separating slag and regulating water volume. The clean water tank is designed to stay for 2 hours, which is used to collect the effluent after the system treatment, and to realize the recycling of resources in time.

[0069] In some embodiments of the present application, an oil-sediment separator and a water distribution system are detachably provided in the pretreatment tank 100. It is understandable that the aerobic biological internal circulation system configured by the filling area 110 is composed of a combination of standardized assembled treatment units, a supporting water distribution system, a biological filter material system, and a dual role of plant oxygen supply and enhanced natural reoxygenation to achieve efficient removal of organic matter.

[0070] In some embodiments, the pretreatment tank 100 is provided with an oil and sediment separation facility, which can effectively separate a small amount of sediment, animal and plant oils, impurities, etc., which are smaller particles in the sewage, to prevent the aerobic biological system in the tank from being blocked and short-circuited by the impurities, thereby ensuring the treatment efficiency of the aerobic biological system. In some embodiments, the aerobic biological internal circulation system configured by the filling area 110 is filled with high-efficiency biological fillers, and the biological fillers are integrated with the aerobic biological internal circulation system and combined with the automatic water distribution system to achieve the removal of organic matter.

[0071] In some embodiments of the present application, an electric control cabinet and a mounting bracket are further included, the photovoltaic panel assembly 300 is arranged on the mounting bracket with an adjustable tilt angle, and the electric control cabinet is electrically connected to the aeration component 200, the control device and the photovoltaic panel assembly 300. It can be understood that the mounting bracket is pre-buried and installed on site, so that the photovoltaic panel assembly 300 can be reliably installed and work normally, and the electric control cabinet is used to meet the normal operation of the power system, so that the photovoltaic micro-power aeration integrated device can operate for a long time.

[0072] In some embodiments of the present application, the air supplied during aerobic treatment is used to "gas lift" the organic wastewater, generating a circulation in the tank so that aerobic microorganisms can fully contact the organic matter in the sewage, thereby achieving the purpose of improving the utilization rate of oxygen and reducing the hydraulic retention time. An automatic water distribution system is provided to ensure uniform water distribution in the enhanced pretreatment tank 100, further avoiding the occurrence of short-circuit in the tank; at the same time, it reduces the impact of the tidal changes of the incoming water on the treatment effect of the enhanced pretreatment tank 100.

[0073] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
