Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0029] See also Figure 1-6 The present invention provides a technical solution: a filling pipeline wastewater recovery device of the present invention includes: a temporary storage tank 1, which is used to store the extracted wastewater; a first sedimentation tank 2, which is connected to the temporary storage tank 1 through a conduit, and the first sedimentation tank 2 is used to perform preliminary sedimentation treatment on the wastewater discharged from the temporary storage tank 1; a second sedimentation tank 3, which is connected to the first sedimentation tank 2 through a conduit, and the second sedimentation tank 3 is used to further sedimentate the wastewater discharged from the first sedimentation tank 2; a filtering mechanism 4, which is connected to the inside of the second sedimentation tank 3; a first storage box 5, which is connected to one side of the second sedimentation tank 3 through a conduit, and the first storage box 5 is used to recover the wastewater treated in the second sedimentation tank 3; a purification mechanism 6, which is connected to the other side of the second sedimentation tank 3 through a conduit, and the purification mechanism 6 is used to purify the wastewater treated in the second sedimentation tank 3 again; a second storage tank 7, which is connected to the purification mechanism 6 through a conduit.

[0030] In this embodiment, the temporary storage tank 1 is used to receive and store the wastewater drawn out from the filling pipe, which serves as the starting part of the entire wastewater recovery system, ensuring that the wastewater can undergo subsequent treatment processes. The wastewater discharged from the temporary storage tank 1 is subjected to preliminary sedimentation treatment through the first sedimentation tank 2 to remove larger particles and impurities. The larger particles and sediments in the wastewater can be effectively removed through the first sedimentation tank 2, providing a cleaner water source for subsequent treatment and improving the subsequent treatment effect. The wastewater discharged from the first sedimentation tank 2 is further subjected to sedimentation treatment through the second sedimentation tank 3 to remove fine particles and suspended matter. Multi-stage sedimentation can further purify the water quality, ensuring that the particulate matter content of the wastewater reaches a lower level, providing cleaner water for filtration and purification.

The wastewater is stored in the first storage tank 5. The water that has undergone preliminary treatment can effectively improve the utilization efficiency of water resources and provide guarantees for future use. The chemical, physical and biological purification treatments are carried out through the purification mechanism 6 to further deeply purify the wastewater. Deep purification can effectively remove harmful substances in the wastewater, so that the wastewater meets higher usage standards and is suitable for more application scenarios. The purified water is stored in the second storage tank 7 for reuse or other purposes, further improving the reuse rate of wastewater and optimizing the utilization efficiency of water resources. By adopting multi-stage treatment methods such as preliminary sedimentation, secondary sedimentation, filtration and deep purification, particulate matter, suspended matter and dissolved pollutants in the water are effectively removed to ensure the thoroughness of wastewater treatment. This not only solves the problems of poor wastewater treatment effect and serious waste of water resources in the existing technology, but also improves the efficiency of water resource recovery and wastewater treatment effect through efficient multi-stage treatment and intelligent design, and has good economy and environmental protection.

[0031] Among them, control valves and pump boxes are installed on the conduit. The conduit system is used to connect various processing units. The control valves and pump boxes are used to adjust the water flow, control the direction and flow rate of the water flow. Through the control valves and pump boxes, the water flow rate can be accurately adjusted to ensure the efficiency and stability of each processing link.

[0032] Specifically, a large amount of sludge in the wastewater entering the temporary storage tank 1 has been removed, and all components and control valves and pump boxes are centrally and automatically controlled by the control box.

[0033] like Figure 2 and Figure 4 As shown, a first partition plate 201 and a second partition plate 202 are provided inside the first sedimentation tank 2, and a plurality of through holes are provided on the upper parts of the first partition plate 201 and the second partition plate 202; the wastewater entering the first sedimentation tank 2 can be initially settled through the first partition plate 201 and the second partition plate 202, and the height of the first partition plate 201 is higher than that of the second partition plate 202.

[0034] like Figure 1 and Figure 3 As shown, a first buffer plate 31, a second buffer plate 32 and a third buffer plate 33 are provided inside the second sedimentation tank 3, a plurality of buffer columns 34 are provided on the first buffer plate 31, and a pusher assembly 35 is provided between the second buffer plate 32 and the third buffer plate 33; the wastewater entering the second sedimentation tank 3 is buffered by the first buffer plate 31, the second buffer plate 32 and the third buffer plate 33, and the buffer column 34 further buffers the wastewater impacting the first buffer plate 31, thereby enhancing the stability of the wastewater flow and improving the sedimentation effect.

[0035] like Figure 3 and Figure 5 As shown, the filtering mechanism 4 includes a filter screen 41, which is connected to the third buffer plate 33, and a cleaning component 42 is connected above the filter screen 41, and the cleaning component 42 is detachably connected to the second sedimentation tank 3, and the cleaning component 42 includes a fixing plate 43, which is connected to the second sedimentation tank 3, and a driving motor 44 is provided on the fixing plate 43, and the driving motor 44 is connected to one end of the first driving rod 45, and the first driving plate 46 is threadedly connected to the first driving rod 45, and the first driving plate 46 is connected to the brush plate 47 below; the wastewater in the second sedimentation tank 3 can be filtered through the filter screen 41, and by controlling the operation of the driving motor 44, the first driving rod 45 can be driven to rotate, and the first driving plate 46 and the brush plate 47 below it can be driven to move back and forth, and the filter screen 41 can be cleaned through the brush plate 47 to avoid clogging of the mesh of the filter screen 41 and improve the filtering effect.

[0036] Among them, a limiting slide rod 48 is set on one side of the first driving rod 45, and a sliding hole adapted to the limiting slide rod 48 is opened on the first driving plate 46; the first driving plate 46 can be limited by the limiting slide rod 48, thereby enhancing the stability of the first driving plate 46 and the brush plate 47 during movement.

[0037] like Figure 1 and Figure 2As shown, the purification mechanism 6 includes a chemical reaction tank 61, a biological reaction tank 62 and a purification tank group 63. One end of the chemical reaction tank 61 is connected to the second sedimentation tank 3 through a conduit, and the other end of the chemical reaction tank 61 is connected to the biological reaction tank 62 through a conduit. One end of the biological reaction tank 62 is connected to the purification tank group 63 through a conduit, and one end of the purification tank group 63 is connected to the second storage tank 7. The chemical reaction tank 61 is the first step in wastewater treatment. It mainly reacts with pollutants in the wastewater by adding chemical agents to cause chemical changes in the pollutants to form easily removable precipitates. The chemical reaction tank 61 is connected to the second sedimentation tank 3 through a conduit. The precipitates in the reaction tank will be further removed by the sedimentation tank, thereby reducing suspended matter and large particle pollutants in the water. The biological reaction tank 62 mainly uses microorganisms to decompose organic pollutants in the water through biodegradation. There is usually a specific microbial community in this pool, which can effectively decompose biodegradable organic matter in the water. The biological reaction tank 62 receives the treated water from the chemical reaction tank, further removes soluble organic matter, and optimizes the water quality through biodegradation and adsorption. Through the coordination of the chemical reaction tank, the biological reaction tank and multiple purification tanks, multi-level and multi-dimensional treatment of wastewater is achieved to ensure that the treated water quality meets the standards.

[0038] Commonly used chemical agents include flocculants, oxidants, and reducing agents, which can effectively remove toxic substances and dissolved pollutants (such as heavy metal ions, ammonia nitrogen, and oils) from water, forming settleable solids that facilitate subsequent physical removal. These microorganisms can convert organic matter (such as ammonia nitrogen and dissolved organic matter) in water into harmless substances, usually carbon dioxide and water.

[0039] Specifically, the purification tank group 63 includes a physical adsorption tank 631, a chemical adsorption tank 632, a fine filtration tank 633 and a membrane filtration tank 634 connected in sequence; the physical adsorption tank 631 uses activated carbon or other adsorption materials to remove organic pollutants, pigments, volatile substances, etc. in the water through physical adsorption, and the chemical adsorption tank 632 uses chemical adsorption materials, such as ion exchange resins or special adsorbents, to remove heavy metal ions, inorganic substances and other harmful substances in the wastewater. The fine filtration tank 633 uses microfiltration or sand filtration technology to further remove suspended matter, tiny particles and residual sediment in the water. The membrane filtration tank 634 uses ultrafiltration (UF), nanofiltration (NF) or reverse osmosis (RO) membrane technology to completely remove fine particles, bacteria, viruses and soluble salts in the water. The four-fold purification process of physical adsorption, chemical adsorption, fine filtration and membrane filtration can efficiently remove various pollutants in the water, including large particle pollutants, dissolved organic matter, heavy metal ions, bacteria, viruses, etc.

[0040] like Figure 3 and Figure 6As shown, the debris pushing component 35 includes a servo motor 351, the servo motor 351 is connected to the second sedimentation tank 3, the servo motor 351 is connected to one end of the second driving rod 352, the second driving rod 352 is provided with a second driving plate 353, and the second driving plate 353 is connected to the bottom of the scraper 354; by controlling the operation of the servo motor 351, the second driving rod 352 can be driven to rotate, and the second driving plate 353 and the scraper 354 connected thereto can be driven to move horizontally, so that the debris deposited between the second buffer plate 32 and the third buffer plate 33 inside the first tank body 1 can be pushed to the cleaning door on one side of the second sedimentation tank 3, so as to facilitate the treatment of the sediment.

[0041] A method for using a filling pipe wastewater recovery device, the method steps specifically include: S1, wastewater flows into a temporary storage tank 1, and the temporary storage tank 1 stores wastewater from the filling pipe; S2: the wastewater passes through a first sedimentation tank 2 for preliminary sedimentation to remove larger particles and impurities; S3: the water after preliminary sedimentation flows into a second sedimentation tank 3 to further settle fine particles and suspended matter; S4: the wastewater after secondary sedimentation passes through a filtering mechanism 4 to remove fine impurities in the water; S5: the first storage tank 5 stores the filtered wastewater for standby or reuse; S6: part of the wastewater in the second sedimentation tank 3 is further purified and enters a purification mechanism 6 for deep treatment. The purified wastewater flows into a second storage tank 7 and can be used for reuse or other purposes after storage.

[0042] In this embodiment, through the sedimentation steps of the first sedimentation tank 2 and the second sedimentation tank 3, large particles are first removed, and then fine particles are further removed, reducing the suspended matter content in the water, laying a good foundation for the subsequent filtration and purification steps. The filtering mechanism 4 removes fine impurities in the water through a fine filter mesh, improves the water quality, and ensures that the purification process is more efficient. After multi-layer treatment, the wastewater is stored in the first storage tank 5 and the second storage tank 7 respectively, providing a backup water source or for reuse. After purification, the water 6 can be further used for industrial production or other purposes, maximizing the recycling rate of wastewater and reducing dependence on fresh water sources. Water storage at different stages can be used flexibly according to demand. For example, filtered water can be temporarily stored for emergency use, while water after deep purification can be directly used for reuse or other high-demand application scenarios. Wastewater recycling and purification can reduce the demand for external water sources and reduce water bills. By adopting a highly efficient recycling and treatment method, wastewater discharge and pollution are reduced, and environmental protection costs are also saved. Through this wastewater recovery device method, while ensuring efficient treatment, it is possible to maximize the recovery and utilization of wastewater resources, not only saving water resources, but also reducing the impact of wastewater discharge on the environment, meeting the needs of sustainable development. Through multi-stage purification, automated design, deep purification treatment and other measures, this method not only improves water quality, but also reduces operating and maintenance costs, which is of great significance to environmental protection.

[0043] Working principle: The wastewater drawn from the filling pipe is received and stored by the temporary storage tank 1, and the wastewater discharged from the temporary storage tank 1 is subjected to preliminary sedimentation treatment through the first sedimentation tank 2 to remove larger particles and impurities. The larger particles and sediments in the wastewater can be effectively removed by the first sedimentation tank 2, providing a cleaner water source for subsequent treatment and improving the subsequent treatment effect. The wastewater discharged from the first sedimentation tank 2 is further subjected to sedimentation treatment by the second sedimentation tank 3 to remove fine particles and suspended matter. The filtering mechanism 4 removes fine impurities in the water through the filter net, further cleans the wastewater, improves the water quality, and removes tiny impurities. The water that has undergone preliminary treatment is stored in the first storage tank 5, which can effectively improve the utilization efficiency of water resources and provide guarantees for future use. The purification mechanism 6 performs chemical, physical and biological purification treatments to further deeply purify the wastewater. Deep purification can effectively remove harmful substances in the wastewater, so that the wastewater meets higher usage standards and is suitable for more application scenarios.
