Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to a multi-energy synergistic power supply system and method for the recycling and treatment of yellow water resources. Background Technology

[0002] Yellow water usually refers to mixed sewage containing urine and flushing fluid. This sewage mainly comes from toilet wastewater and is rich in nutrients such as nitrogen (about 80 wt%), phosphorus (about 50 wt%), and potassium (about 60 wt%). If it is directly discharged into the aquatic environment, the nitrogen, phosphorus, potassium and other nutrients in the yellow water will cause eutrophication of the water body, causing algae and other organisms in the water to reproduce abnormally and consume more dissolved oxygen. Fish and other organisms in the water will die due to lack of oxygen, further disrupting the ecological balance of the water body.

[0003] Traditional methods of treating toilet wastewater increase the load and operating costs of wastewater treatment plants, and also waste nutrients such as nitrogen, phosphorus, and potassium, which can be used as high-quality fertilizers for plant growth. Therefore, effectively treating yellow wastewater while simultaneously extracting its nutrients is of great significance for resource utilization.

[0004] Patent CN110407358A discloses a method and apparatus for resource-based treatment of source-separated yellow water, which includes a nanofiltration device and a struvite crystallization device. The source-separated yellow water passes through a security filter group, reducing the risk of nanofiltration membrane clogging. After nanofiltration, ammonia nitrogen and phosphorus are concentrated, while pathogenic microorganisms and other harmful substances are trapped and separated. The nanofiltration effluent serves as the influent for the struvite crystallization device, where nitrogen, phosphorus, and magnesium react chemically with added magnesium and phosphorus sources to form magnesium ammonium phosphate precipitate. After filtration, washing, and drying, this precipitate can be used as a slow-release fertilizer for the fields. However, this patent requires the addition of additional chemicals, and the membrane modules are prone to fouling, resulting in high operating costs.

[0005] Patent CN216972052U discloses a solar evaporation device for treating laboratory wastewater. This patent uses a concave mirror to absorb and focus light energy to heat the water in the evaporation chamber. It does not require any power supply. However, the disadvantage is that it cannot achieve the sustainability and efficiency of wastewater resource recovery in areas with insufficient power supply or drastic weather changes.

[0017] A method for recycling and treating yellow water resources, employing the aforementioned multi-energy synergistic yellow water resource recycling and treatment system, includes the following steps:

[0018] S1. Control the original liquid booster pump to transport the original yellow water source to the original liquid chamber. The original yellow water is filtered through the filter screen to remove suspended solids and coarse particulate impurities, and the resulting yellow water filtrate is stored in the filtrate chamber. When there is sufficient sunlight, the solar collector tube absorbs solar energy and converts it into heat energy to heat the yellow water filtrate, thus preparing for the evaporation and solidification of the yellow water filtrate.

[0019] S2. Control the filtrate lifting pump to transport the yellow water filtrate in the filtrate chamber to the spray component and spray it onto the evaporation and solidification surface. At the same time, control the spray component to move downwards to the correct position and then upwards to the initial position to spray the yellow water filtrate onto the entire evaporation and solidification surface. When there is sufficient sunlight, the evaporation and solidification surface absorbs solar energy and converts it into heat energy. When there is insufficient sunlight, the evaporation and solidification surface absorbs heat energy generated through the heating resistance wire interlayer to heat the yellow water filtrate sprayed onto the evaporation and solidification surface, causing the yellow water filtrate to evaporate, solidify, crystallize, and form yellow water crystals.

[0020] S3. When the yellow water crystals on the evaporation and curing surface reach a certain thickness, control the scraping component to move upward to scrape off the yellow water crystals on the evaporation and curing surface. After the scraping component moves upward into place, control the scraping component to move downward to the initial position and repeat steps S2-S3. The multi-energy clean power supply unit supplies power to the drive source of the original liquid lifting pump, the filtrate lifting pump, the resistance wire jacket, the spray component, and the scraping component.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The multi-energy synergistic power supply system for yellow water resource recycling and treatment in this invention includes a pretreatment unit, an evaporation and solidification collection unit, and a multi-energy clean power supply unit. During the recycling and treatment of yellow water resources, a raw liquid booster pump is first controlled to transport the raw yellow water from the source to the raw liquid chamber. The raw yellow water is filtered through a filter screen to remove suspended solids and coarse particulate impurities, resulting in yellow water filtrate, which is stored in the filtrate chamber. When there is sufficient sunlight, solar collectors absorb solar energy and convert it into heat energy to heat the yellow water filtrate, preparing it for evaporation and solidification. The filtrate booster pump is then controlled to transport the yellow water filtrate from the filtrate chamber to the spraying component and spray it onto the evaporation and solidification surface. The spraying component is controlled to move downwards to its designated position and then upwards back to its initial position to spray the yellow filtrate onto the entire evaporation and curing surface. When there is sufficient sunlight, the evaporation and curing surface absorbs solar energy and converts it into heat energy. When there is insufficient sunlight, the evaporation and curing surface absorbs heat energy generated through the heating resistance wire interlayer to heat the yellow filtrate sprayed onto the evaporation and curing surface, causing the yellow filtrate to evaporate, solidify, and crystallize to form yellow filtrate crystals. When the yellow filtrate crystals on the evaporation and curing surface reach a certain thickness, the scraping component is controlled to move upwards to scrape off the yellow filtrate crystals on the evaporation and curing surface. After the scraping component moves upwards to its designated position, it is controlled to move downwards back to its initial position, and the above operation is repeated. This system allows the solar collector tube to absorb solar energy and convert it into heat to heat the yellow water filtrate, thus preheating it for evaporation and solidification. This improves the evaporation and solidification efficiency of the yellow water filtrate. Furthermore, the transparent shell allows light to pass through, and it features a resistance wire interlayer and a heat-conducting layer on its inner surface, forming an evaporation and solidification surface. Under sufficient sunlight, this surface directly absorbs solar energy and converts it into heat. When sunlight is insufficient, the surface absorbs heat generated by heating the resistance wire interlayer, heating the yellow water filtrate sprayed onto it. This causes the filtrate to evaporate, solidify, and crystallize, forming yellow water crystals. Therefore, the resistance wire interlayer allows for continuous evaporation and solidification of the yellow water filtrate sprayed onto the surface, significantly improving evaporation and solidification efficiency and the number of crystals. Additionally, the multi-energy clean power supply unit enables the combined supply of various clean energy sources. Attached Figure Description

Detailed Implementation

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0030] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for 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. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and 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.

[0032] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0033] like Figure 1 and Figure 2 As shown, a multi-energy synergistic power supply system for the recycling and treatment of yellow water resources includes a pretreatment unit, an evaporation and solidification collection unit, and a multi-energy clean power supply unit. The pretreatment unit includes a solar collector tube 2 with an internal filter screen 1. The filter screen 1 divides the inner cavity of the solar collector tube 2 into a raw liquid chamber 201 and a filtrate chamber 202. The raw liquid chamber 201 is connected to the yellow water source through a raw liquid booster pump 3. The evaporation and solidification collection unit includes a light-transmitting shell 4 sleeved on the outside of the solar collector tube 2. The light-transmitting shell 4 has a resistance wire interlayer and a resistance wire layer on its inner surface. A heat-conducting layer is formed to create an evaporation and curing surface 402. A spray component and a scraping component that can move up and down are provided between the solar collector tube 2 and the light-transmitting shell 4. The spray component is connected to the filtrate chamber 202 through a filtrate lift pump and is used to spray the yellow water filtrate in the filtrate chamber 202 onto the evaporation and curing surface 402. The scraping component is used to scrape off the yellow water crystals on the evaporation and curing surface 402. A multi-energy clean power supply unit is used to supply power to the original liquid lift pump 3, the filtrate lift pump, the resistance wire jacket, the spray component, and the scraping component.

[0034] When recycling and processing yellow water resources, the raw liquid lift pump 3 is first controlled to transport the raw yellow water from the source to the raw liquid chamber 201. The raw yellow water is filtered through the filter screen 1 to remove suspended solids and coarse particulate impurities, resulting in yellow water filtrate, which is stored in the filtrate chamber 202. When there is sufficient sunlight, the solar collector tube 2 absorbs solar energy and converts it into heat energy to heat the yellow water filtrate, preparing it for evaporation and solidification. The filtrate lift pump is then controlled to transport the yellow water filtrate in the filtrate chamber 202 to the spray component and spray it onto the evaporation and solidification surface 402. Simultaneously, the spray component is controlled to move downwards to its designated position and then upwards back to its initial position to further process the yellow water. The water filtrate is sprayed onto the entire evaporation and curing surface 402. When there is sufficient sunlight, the evaporation and curing surface 402 absorbs solar energy and converts it into heat energy. When there is insufficient sunlight, the evaporation and curing surface 402 absorbs the heat energy generated through the heating resistance wire interlayer to heat the yellow water filtrate sprayed onto the evaporation and curing surface 402, causing the yellow water filtrate to evaporate, solidify, and crystallize to form yellow water crystals. When the yellow water crystals on the evaporation and curing surface 402 reach a certain thickness, the scraping component is controlled to move upward to scrape off the yellow water crystals on the evaporation and curing surface 402. After the scraping component moves upward into place, it is controlled to move downward to the initial position, and the above operation is repeated.

[0035] In this way, the solar collector tube 2 can absorb solar energy and convert it into heat energy to heat the yellow water filtrate, thus preheating it for evaporation and solidification, thereby improving the evaporation and solidification efficiency of the yellow water filtrate. Moreover, since the light-transmitting shell 4 is light-transmitting, it is equipped with a resistance wire interlayer and a heat-conducting layer on its inner side, forming an evaporation and solidification surface 402. In this way, when there is sufficient sunlight, the evaporation and solidification surface 402 directly absorbs solar energy and converts it into heat energy. When there is insufficient sunlight, the evaporation and solidification surface 402 absorbs the heat energy generated by heating the resistance wire interlayer to heat the yellow water filtrate sprayed onto the evaporation and solidification surface 402, causing the yellow water filtrate to evaporate, solidify, and crystallize to form yellow water crystals. Therefore, the setting of the resistance wire interlayer allows the yellow water filtrate sprayed onto the evaporation and solidification surface 402 to continuously evaporate and solidify for 24 hours, which can significantly improve the evaporation and solidification efficiency of the yellow water filtrate and the number of yellow water crystals. In addition, the multi-energy clean energy supply unit can realize the combined power supply of various clean energy sources.

[0036] The multi-energy clean energy supply unit includes a solar power generation component and a biogas power generation component. The solar power generation component includes a solar photovoltaic panel 7, a first power management component, and a battery. The solar photovoltaic panel 7 is electrically connected to the raw liquid lift pump 3, the filtrate lift pump, the drive source of the spray component, and the drive source of the scraping component through the first power management component. The solar photovoltaic panel 7 is also connected to the input end of the battery. The output end of the battery is electrically connected to the raw liquid lift pump 3, the filtrate lift pump, the resistance wire jacket, the drive source of the spray component, and the drive source of the scraping component through the second power management component. The biogas power generation component includes a biogas generator set 9 and a third power management component. The biogas generator set 9 is connected to the anaerobic biogas digester and is electrically connected to the raw liquid lift pump 3, the filtrate lift pump, the resistance wire jacket, the drive source of the spray component, and the drive source of the scraping component through the third power management component.

[0037] In one embodiment, the multi-energy clean power supply unit further includes a light sensor, a power supply control component, and a power switching switch. The light sensor is connected to the signal input terminal of the power supply control component, and the power supply control component controls the on / off state of the first power supply management component, the second power supply management component, and the third power supply management component via the power switching switch. Figure 3 Preferably, the power supply control component is a PLC controller.

[0038] In this way, the light intensity at the location of the multi-energy collaborative power supply system for the yellow water resource recycling and treatment is detected by a light sensor and transmitted to the power supply control component. The power supply control component compares the received light intensity with a pre-stored light intensity threshold. When the received light intensity is greater than the light intensity threshold, it indicates that the light is sufficient. The power supply control component then controls the first power supply management component to be turned on via a power switching switch. The solar photovoltaic panel 7 absorbs solar energy and converts it into electrical energy to power the drive source of the raw liquid lift pump 3, the filtrate lift pump, the spray component, and the scraping component. Excess electrical energy converted by the solar photovoltaic panel 7 is stored in the battery. When the received light intensity is less than the light intensity threshold, it indicates that the light is insufficient. The power supply control component then controls the second and third power supply management components to be turned on via a power switching switch. The biogas generator set 9 generates electrical energy from biogas generated in the anaerobic biogas digester and uses the electrical energy stored in the battery to power the drive source of the raw liquid lift pump 3, the filtrate lift pump, the resistance wire jacket, the spray component, and the scraping component.

[0039] This invention connects a biogas generator set 9 to the anaerobic biogas digester of a rural sewage treatment plant or a rural household toilet, reducing dependence on external power and realizing the resource utilization of organic waste. At the same time, biogas, as a green energy source, has the characteristics of low carbon emissions, further enhancing the environmental friendliness of the system.

[0040] In one embodiment, the multi-energy collaborative power supply system for yellow water resource recycling and treatment further includes a main control unit electrically connected to the first power supply management component, the second power supply management component, and the third power supply management component; a water level sensor 5 is installed in the filtrate chamber 202, the water level sensor 5 is electrically connected to the signal input terminal of the main control unit, and the signal output terminal of the main control unit is electrically connected to the raw liquid booster pump 3. Figure 4 A crystal sensor 6 is installed on the light-transmitting housing 4 to detect the thickness of the yellow water crystals crystallized on the evaporation and curing surface 402. The crystal sensor 6 is electrically connected to the signal input terminal of the main control unit, and the signal output terminal of the main control unit is electrically connected to the drive source of the scraping component. See [link to documentation]. Figure 5 And by controlling the drive source of the scraping component, the scraping component is moved up and down.

[0041] The water level sensor 5 detects the water level in the filtrate chamber 202 and transmits it to the main control unit. The main control unit compares the received water level with the pre-stored highest and lowest water levels in the filtrate chamber 202. When the received water level is lower than the lowest water level, the yellow filtrate in the filtrate chamber 202 is below the lowest water level line 204. The main control unit controls the original liquid lift pump 3 to operate, so as to replenish the yellow filtrate in the original liquid chamber 201. When the received water level is higher than the highest water level, the yellow filtrate in the filtrate chamber 202 is above the highest water level line 205. The main control unit controls the original liquid lift pump 3 to stop operating, so as to stop replenishing the yellow filtrate in the original liquid chamber 201.

[0042] Furthermore, the thickness of the yellow water crystals crystallized on the evaporation and curing surface 402 is detected by the crystal sensor 6 and transmitted to the main control unit. The main control unit compares the received thickness of the yellow water crystals with the pre-stored thickness threshold of the yellow water crystals. When the received thickness of the yellow water crystals is greater than the thickness threshold, the main control unit controls the drive source of the scraping component to move upward and scrape off the yellow water crystals on the evaporation and curing surface 402. After the scraping component moves upward into place, the main control unit controls the drive source of the scraping component to reverse and move the scraping component downward to the initial position.

[0043] In one embodiment, the solar photovoltaic panel 7 is foldable and supported and fixed by the support frame 8. The support frame 8, the biogas generator set 9 and the raw liquid lifting pump 3 located outside the light-transmitting shell 4 are all detachably connected to the light-transmitting shell 4 through quick-connect interfaces. The outer side of the light-transmitting shell 4 is provided with a handle 10 and the bottom surface is provided with universal casters 11.

[0044] The foldable solar photovoltaic panel 7, along with the handle 10 and omnidirectional casters 11, facilitates the transportation and assembly of this yellow water resource recycling and treatment system, and allows for rapid deployment in different application scenarios. The support frame 8 is made of carbon fiber composite material, making the equipment lightweight, high-strength, and corrosion-resistant, thus reducing maintenance costs.

[0045] In one embodiment,

[0046] The light-transmitting housing 4 is a vertical cylindrical shape with an open top. The solar collector tube 2 is a vertical cylindrical shape and is located in the middle of the inner bottom surface of the light-transmitting housing 4. The filter screen 1 is horizontally arranged inside the solar collector tube 2. The raw liquid chamber 201 is located above the filter screen 1, and the filtrate chamber 202 is located below the filter screen 1. The spray component includes a spray ring 1201, which is a horizontal annular shape. The vertical center line of the spray ring 1201 coincides with the vertical center line of the solar collector tube 2. Multiple atomizing nozzles 120 are provided on the outer surface of the spray ring 1201. 2. The spray ring 1201 is driven to move up and down relative to the solar collector tube 2 by the first lifting component; the scraping component includes a scraper 1301, which is a vertical and hollow frustum shape with an upper port diameter larger than the lower port diameter. The vertical center line of the scraper 1301 coincides with the vertical center line of the spray ring 1201. The lower port diameter of the scraper 1301 is larger than the outer diameter of the spray ring 1201. Multiple scrapers 1302 are provided on the outer side of the scraper 1301. The scraper 1301 is driven to move up and down relative to the solar collector tube 2 by the second lifting component.

[0047] By controlling the filtrate lift pump, the yellow water filtrate in the filtrate chamber 202 is transported to the spray ring 1201 and sprayed onto the evaporation and curing surface 402 through multiple atomizing nozzles 1202. The atomizing nozzles 1202 are arranged at an upward angle, preferably 20°. The diameter of the yellow water filtrate sprayed by the atomizing nozzles 1202 is controlled to be 150 μm to minimize the droplet formation and flow of the sprayed yellow water filtrate onto the evaporation and curing surface 402 due to gravity.

[0048] The scraper 1301 is driven upward by the second lifting component, and multiple scrapers 1302 on the outer surface of the scraper 1301 move upward along with the scraper 1301, scraping off the yellow water crystals on the evaporation and curing surface 402. The scrapers 1302 are arranged at a downward angle, preferably 15°, to fully scrape off the yellow water crystals and improve the recovery rate of the yellow water crystals. The scraper 1301 is coated with an acrylic waterproof coating.

[0049] By designing the solar collector tube 2 as a cylindrical shape, it can absorb solar energy from all directions in 360°, thereby improving the preheating efficiency of the yellow water filtrate. By designing the light-transmitting shell 4 as a cylindrical shape, it is easy for the evaporation and solidification surface 402 to absorb solar energy from all directions in 360°, thereby improving the evaporation and solidification efficiency of the yellow water filtrate.

[0050] Preferably, the first lifting component includes a first lead screw 2301 vertically disposed on the outer surface of the solar collector tube 2, a first nut 2302 screwed onto the first lead screw 2301, the first nut 2302 slidingly engaging with a first guide rail on the outer surface of the solar collector tube 2, and the spray ring 1201 detachably connected to the first nut 2302 via a first fixed bracket 14. The driving source for the spray component is a first motor, and the first lead screw 2301 is driven to rotate by the first motor. The first power management component, the second power management component, and the third power management component are all electrically connected to the first motor. The connection includes a second lead screw 2401 vertically disposed on the outer side of the solar collector tube 2, a second nut 2402 screwed onto the second lead screw 2401, the second nut 2402 slidingly engaging with a second guide rail on the outer side of the solar collector tube 2, a scraper 1301 detachably connected to the second nut 2402 via a second fixed bracket 15, a second motor driving the scraping component, the second lead screw 2401 being driven to rotate by the second motor, and the first power management component, the second power management component, and the third power management component all being electrically connected to the second motor.

[0051] Preferably, a crystal storage box 16 with a top opening and whose shape and size are adapted to the scraper 1301 is arranged inside the light-transmitting housing 4 directly below the scraper 1301. The gap between the inner side of the crystal storage box 16 and the outer side of the scraper 1301 forms a crystal recycling port 17. A unidirectional exhaust fan 18 is arranged inside the light-transmitting housing 4 near the top opening.

[0052] The yellow water crystals scraped off fall from the crystal recovery port 17 into the crystal storage box 16, and then the yellow water crystals in the crystal storage box 16 are collected by disassembling the scraper 1301.

[0053] The unidirectional exhaust fan 18 can remove the water vapor generated during the evaporation and solidification process of the yellow water filtrate, thus preventing excessive humidity inside the light-transmitting housing 4 and reducing the evaporation and solidification efficiency of the yellow water filtrate.

[0054] Preferably, the inlet of the raw liquid booster pump 3 is connected to the yellow water source through the yellow water suction pipe 19, and the outlet of the raw liquid booster pump 3 is connected to the yellow water inlet 203 on the top wall of the solar collector tube 2 through the yellow water delivery pipe 20. The bottom wall or side wall of the light-transmitting shell 4 is provided with a yellow water recovery port 401, which is connected to the inlet of the raw liquid booster pump 3 through the yellow water recovery pipe 21. The filtrate chamber 202 is connected to the spray ring 1201 through the yellow water filtrate pipe 22, and the filtrate booster pump is connected to the yellow water filtrate pipe 22. The light-transmitting shell 4 is made of polycarbonate. The polycarbonate hollow plate has a resistance wire interlayer inside its cavity. The inner side of the light-transmitting shell 4 is laser-engraved with multiple grooves and coated with a graphite epoxy resin coating as a heat-conducting layer. The solar collector tube 2 is made of polycarbonate. From the inside to the outside, the outer side of the solar collector tube 2 is provided with an insulation layer, a light-absorbing layer, and a corrosion-resistant layer. The insulation layer is made of SiO2 aerogel coating, the light-absorbing layer is a black chrome coating, and the corrosion-resistant layer is a transparent fluorocarbon resin. The resistance wire interlayer is a chromium alloy resistance wire interlayer. The filter 1 is a grid filter 1.

[0055] In this way, during the process of spraying the yellow water filtrate onto the evaporation and curing surface 402, the excess yellow water filtrate can be recycled back into the circulation through the yellow water recovery port 401 and the yellow water recovery pipe 21 in sequence.

[0056] The light-transmitting shell 4 is a hollow polycarbonate sheet with high light transmittance, reaching 85-90%, and a density of 1.2 g / cm³. 3 It is extremely lightweight, yet its impact resistance is 250 times that of glass. It is resistant to acids, alkalis, rain, and salt spray, making it suitable for long-term outdoor use.

[0057] The grooves are 200μm wide and 500μm deep, with a spacing of 1mm between adjacent grooves. By setting multiple grooves, the hydrophilicity of the evaporation curing surface 402 can be enhanced.

[0058] A graphite epoxy resin coating is used as a thermally conductive layer to form an evaporation curing surface 402. Due to the high thermal conductivity and porous structure of graphite, heat transfer and liquid vaporization can be enhanced, and it is resistant to acids, alkalis and most organic solvents. The mixed epoxy resin spraying process can enhance the adhesion and stability of the coating.

[0059] A black chrome coating is used as the light-absorbing layer on the outer surface of the solar collector tube 2. The light absorption rate of this layer is 95%~98%, and the thermal conductivity is 0.02~0.05 W / m·K. It has high absorption efficiency, low heat radiation loss, and a service life of more than 15 years.

[0060] A method for recycling and treating yellow water resources, employing the aforementioned multi-energy synergistic yellow water resource recycling and treatment system, includes the following steps:

[0061] S1. Control the original liquid booster pump 3 to transport the original liquid of the yellow water source to the original liquid chamber 201. The original liquid of the yellow water is filtered through the filter screen 1 to remove suspended solids and coarse particulate impurities, and the yellow water filtrate is obtained and stored in the filtrate chamber 202. When there is sufficient sunlight, the solar collector tube 2 absorbs solar energy and converts it into heat energy to heat the yellow water filtrate, and prepares for the evaporation and solidification of the yellow water filtrate.

[0062] S2. Control the filtrate lift pump to transport the yellow water filtrate in the filtrate chamber 202 to the spray component and spray it onto the evaporation and solidification surface 402. At the same time, control the spray component to move downwards to the correct position and then upwards to the initial position to spray the yellow water filtrate onto the entire evaporation and solidification surface 402. When there is sufficient sunlight, the evaporation and solidification surface 402 absorbs solar energy and converts it into heat energy. When there is insufficient sunlight, the evaporation and solidification surface 402 absorbs the heat energy generated through the heating resistance wire interlayer to heat the yellow water filtrate sprayed onto the evaporation and solidification surface 402, so that the yellow water filtrate evaporates, solidifies, crystallizes, and forms yellow water crystals.

[0063] S3. When the yellow water crystals on the evaporation and curing surface 402 reach a certain thickness, control the scraping component to move upward to scrape off the yellow water crystals on the evaporation and curing surface 402. After the scraping component moves upward into place, control the scraping component to move downward to the initial position and repeat steps S2-S3. When the multi-energy clean power supply unit supplies power to the driving source of the raw liquid lifting pump 3, the filtrate lifting pump, the resistance wire jacket, the spray component, and the scraping component, when there is sufficient sunlight, the solar photovoltaic panel 7 absorbs solar energy and converts it into electrical energy to supply power to the driving source of the raw liquid lifting pump 3, the filtrate lifting pump, the spray component, and the scraping component. The excess electrical energy converted by the solar photovoltaic panel 7 is stored in the battery. When there is insufficient sunlight, the biogas generator set 9 uses the electrical energy converted from biogas generated by the anaerobic biogas digester and the electrical energy stored in the battery to supply power to the driving source of the raw liquid lifting pump 3, the filtrate lifting pump, the resistance wire jacket, the spray component, and the scraping component.

[0064] This invention can switch the power supply mode according to the light intensity, ensuring that the system operates stably and continuously under different weather conditions.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
