Description

Technical Field

[0001] This utility model relates to a buried sewage treatment device, and more particularly to a buried sewage treatment device with organic matter degradation function applied in the field of sewage treatment technology. Background Technology

[0002] With the acceleration of urbanization and industrialization, the discharge of domestic and industrial wastewater has increased significantly, putting enormous pressure on the environment. This has led to a growing demand for improvements in traditional wastewater treatment methods and for environmentally friendly technologies. Traditional wastewater treatment facilities often occupy large areas, requiring dedicated buildings to house the treatment systems, and may produce odors, affecting the aesthetics of the surrounding environment and the quality of life for residents. Underground wastewater treatment equipment, employing mature technologies such as biological contact oxidation, offers advantages such as high integration, small footprint, automated control, and low maintenance requirements. It is particularly suitable for densely populated areas, areas with limited land, or areas with high requirements for environmental aesthetics. Through optimized design, underground wastewater treatment equipment not only improves wastewater treatment efficiency but also reduces operating costs, becoming an important development direction in the modern wastewater treatment field.

[0003] Patent CN213924410U discloses an underground integrated sewage treatment device, including a box body and a crushing box, as well as a sludge-holding chamber, a reaction chamber, and a clear water chamber located inside the box body. The front and rear ends of the box body are provided with water inlets and drain outlets. A sludge-holding screen is inserted and installed in the sludge-holding chamber. A first crushing roller and a second crushing roller are rotatably arranged inside the crushing box. The bottom of the crushing box is fixedly set to the box body through a base bracket. A feeding hopper is provided on the crushing box. A motor is installed on the crushing box.

A conveying pipe is connected to one end of the crushing box facing the box body. A valve is installed on the conveying pipe. The left end of the conveying pipe is connected to the reaction chamber.

[0004] In the application of this underground sewage treatment equipment, solid matter in the sewage accumulates on the filter screen, which can easily cause blockage and affect the smooth flow of water. During pipeline transportation, scale sticks to the pipe openings, causing poor water flow and reducing sewage treatment efficiency. The sewage treatment process is limited to a single treatment method, and the sludge return treatment effect is poor, which affects the sewage treatment effect. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that solid matter in sewage accumulates on the filter screen, which easily causes blockage and affects the smooth flow of water. During pipeline transportation, scale sticks to the pipe opening, causing poor water flow and reducing sewage treatment efficiency. In the sewage treatment process, the treatment method is singular and the sludge return treatment effect is poor, which affects the sewage treatment effect.

[0006] To address the aforementioned problems, this utility model provides a buried sewage treatment device with organic matter degradation capabilities, comprising a pretreatment tank and a biodegradation tank. A drain pipe is connected to the top of the pretreatment tank. Multiple filter plates are installed sequentially from top to bottom within the pretreatment tank's interior. An inclined conveying trough is connected to the bottom of the pretreatment tank, with the other end of the conveying trough connected to a circulation tank. A circulation pipe is connected to the bottom of the inner wall of the circulation tank, with the other end of the circulation pipe connected to the side wall of the pretreatment tank. A sewage pipe penetrating the biodegradation tank is connected to the bottom of the pretreatment tank near the connection between the conveying trough and the pretreatment tank. A ring of electromagnetic drain valves is installed on the side wall of the biodegradation tank. The biodegradation tank is installed at the bottom of the interior of a waste collection tank. A spring hose cooperating with the electromagnetic drain valves is installed at the bottom of the interior of the biodegradation tank. A scraper blade inserted into the interior of the biodegradation tank is installed at the top of the spring hose. Multiple conveying pipes penetrating the waste collection tank are sequentially connected to the side wall of the biodegradation tank from top to bottom. An electromagnetic valve is installed at the connection between each conveying pipe and the biodegradation tank.

[0007] In the above-mentioned buried sewage treatment equipment with organic matter degradation function, the circulation transport of sewage through the conveying tank and circulation pipe can circulate the sewage for treatment, improve the sewage utilization rate and treatment efficiency, the microorganisms in the biodegradation tank adsorb and degrade organic pollutants, effectively remove nitrogen pollution, and the sludge plate scrapes off the scale on the chamber wall and discharges it through the electromagnetic drain valve, reducing the impact of scale adhesion on sewage treatment.

[0008] As a further improvement of this application, a trigger button is installed at the bottom of the inner cavity of the biodegradation box, a trigger rod that cooperates with the trigger button is installed at the bottom of the scraper, and multiple disc aerators are installed at the top of the scraper.

[0009] As a further improvement of this application, a filter screen is provided at the connection between the circulation pipe and the bottom of the inner cavity of the circulation treatment tank, a filter screen is provided at the connection between the sewage pipe and the primary treatment tank, and a filter screen is provided at the connection between the conveying pipe and the biodegradation tank.

[0010] As a further improvement of this application, a support frame is installed at the bottom of the primary treatment tank, and the other end of the support frame is fixed to one side of the biodegradation tank. Multiple support columns are installed at the bottom of the circulating treatment tank, and the sludge scraper is made of waterproof and high-toughness material.

[0011] As another improvement of this application, the other end of each conveying pipe is connected to a sedimentation tank. A water supply pipe is connected to the side wall of the sedimentation tank. A filter screen is installed at the connection between the water supply pipe and the sedimentation tank. An expansion joint is installed on the inner wall of the sedimentation tank. A baffle that cooperates with the water supply pipe is connected to the output end of the expansion joint. The baffle is made of waterproof and high-toughness material.

[0012] As a further improvement to this application, the other end of the water supply pipe is connected to a purification box, a water purifier is installed on the top of the purification box, a high-pressure water purification pipe is installed around the bottom of the water purifier, and a water purification delivery pipe is connected to the side wall of the purification box.

[0013] In summary, wastewater is transported to the primary treatment tank through the sewage pipe, where it undergoes preliminary filtration through a filter plate. A portion of the wastewater containing large particles that are not completely filtered enters the circulation treatment tank via a conveying trough and is then transported back to the primary treatment tank for further filtration through a circulation pipe. This process improves wastewater utilization and treatment efficiency. After filtration, the wastewater is transported to the biodegradation tank through a sewage pipe. Microorganisms in the biodegradation tank adsorb and degrade organic pollutants, while simultaneously undergoing nitrification and denitrification, effectively removing nitrogen pollution. After the wastewater is conveyed out of the conveying pipe, the spring hose moves the sludge plate upwards, scraping away scale from the chamber walls and discharging it through the electromagnetic drain valve. This effectively reduces the impact of scale adhesion on wastewater treatment. The sludge discharged by the electromagnetic drain valve is collected in the waste collection tank, improving the effectiveness of the reflux treatment and reducing environmental pollution.

[0021] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] First implementation method:

[0023] Figures 1-3 This invention illustrates a buried sewage treatment device with organic matter degradation capabilities, comprising a primary treatment tank 1 and a biodegradation tank 2. A drain pipe 101 is connected to the top of the primary treatment tank 1, through which sewage is transported to the primary treatment tank 1 for preliminary filtration. Multiple filter plates 102 are installed sequentially from top to bottom within the inner cavity of the primary treatment tank 1, filtering out most large particles of waste. An inclined conveying trough 103 is connected to the bottom of the primary treatment tank 1, with the other end of the conveying trough 103 connected to a circulation treatment tank 3. A circulation pipe 104 is connected to the bottom of the inner wall of the circulation treatment tank 3. The other end is connected to the side wall of the primary treatment tank 1. A portion of the wastewater that has not been completely filtered to remove large particles enters the circulating treatment tank 3 through the conveying trough 103, and is then transported back to the primary treatment tank 1 for circulating filtration via the circulating pipe 104. This greatly improves wastewater utilization and treatment efficiency. A wastewater pipe 105, penetrating the biodegradation tank 2, is connected to the bottom of the primary treatment tank 1 near the connection point between the conveying trough 103 and the primary treatment tank 1. The filtered wastewater enters the biodegradation tank 2 through the wastewater pipe 105. A ring of electromagnetic drain valves 201 is installed on the side wall of the biodegradation tank 2 to discharge sludge from the wastewater. Installed at the bottom of the inner cavity of the waste collection tank 21, the biodegradation tank 2 has a spring hose 202 that cooperates with the electromagnetic drain valve 201. A scraper 203, inserted into the inner cavity of the biodegradation tank 2, is installed at the top of the spring hose 202. After wastewater enters the biodegradation tank 2, the spring hose 202 contracts under pressure, causing the scraper 203 to move downwards. Microorganisms present in the biodegradation tank 2 adsorb and degrade organic pollutants carried in the wastewater, while simultaneously carrying out nitrification and denitrification, effectively removing nitrogen pollution. Multiple through-waste valves are connected sequentially from top to bottom to the side wall of the biodegradation tank 2. The waste collection tank 21 has a conveying pipe 204. Each conveying pipe 204 is connected to the biodegradation tank 2 and is equipped with a solenoid valve. After degradation is completed, the solenoid valve is opened to discharge the degraded wastewater through the conveying pipe 204. During the degradation process, scale may remain on the inner wall of the biodegradation tank 2. After the degraded wastewater is discharged, the pressure on the spring hose 202 gradually decreases, and the elasticity is restored, which drives the scraper 203 to move upward. During the process, the scale on the inner wall of the biodegradation tank 2 is scraped off and discharged by the solenoid drain valve 201. The discharged scale is collected by the waste collection tank 21, which reduces pollution and improves the effect of reflux treatment.

[0024] Please see Figure 3A trigger button 205 is installed at the bottom of the inner cavity of the biodegradation tank 2. A trigger rod 206 that cooperates with the trigger button 205 is installed at the bottom of the scraper 203. When the trigger rod 206 moves downward with the scraper 203 and contacts the trigger button 205, the timing is started to control the organic matter degradation stage and the sewage pipe 105 is shut off to transport sewage into the biodegradation tank 2. Multiple disc aerators 207 are installed on the top of the scraper 203 to provide oxygen to the microorganisms in the biodegradation tank 2 and promote the activity of the biofilm.

[0025] Please see Figure 2 and Figure 3 A filter screen is installed at the connection between the circulation pipe 104 and the bottom of the inner cavity of the circulation treatment tank 3, a filter screen is installed at the connection between the sewage pipe 105 and the primary treatment tank 1, and a filter screen is installed at the connection between the conveying pipe 204 and the biodegradation tank 2. The filter screen is installed to filter impurities in the sewage during the sewage conveying process, thereby improving the sewage treatment efficiency.

[0026] Please see Figure 1 and Figure 3 The bottom of the primary treatment tank 1 is equipped with a support frame 106, and the other end of the support frame 106 is fixed to one side of the biodegradation tank 2 for fixing the primary treatment tank 1. The bottom of the circulating treatment tank 3 is equipped with multiple support columns 301 for fixing the circulating treatment tank 3. The sludge scraper 203 is made of waterproof and high-toughness material. The waterproof material greatly reduces the corrosive effect of sewage on the sludge scraper 203, and the high-toughness material reduces the damage caused by sewage impact on the sludge scraper 203, improves durability, and reduces costs.

[0027] In summary, wastewater is transported to the primary treatment tank 1 via the sewage pipe 101 for preliminary filtration. After multiple filtration processes by the various filter plates 102 installed in the primary treatment tank 1, most large particles of wastewater are filtered out. A portion of the wastewater that does not completely filter large particles enters the circulation treatment tank 3 via the conveying trough 103, where it is filtered by the filter screen installed at the connection between the circulation pipe 104 and the circulation treatment tank 3, and then transported back to the primary treatment tank 1 for further filtration, significantly improving wastewater utilization and treatment efficiency. The filtered wastewater then passes through the filter screen installed at the connection between the sewage pipe 105 and the primary treatment tank 1 before entering the primary treatment tank 1. In the biodegradation tank 2, the spring hose 202 contracts under pressure, causing the scraper 203 to move downwards. Microorganisms within the biodegradation tank 2 adsorb and degrade organic pollutants carried in the wastewater, simultaneously undergoing nitrification and denitrification to effectively remove nitrogen pollution. When the trigger rod 206 moves downwards with the scraper 203 and contacts the trigger button 205, it starts timing to control the organic matter degradation stage and shuts off the wastewater pipe 105 from supplying wastewater into the biodegradation tank 2. Multiple disc aerators 207 mounted on the top of the scraper 203 begin operating, providing oxygen to the microorganisms in the biodegradation tank 2, promoting... The biofilm activity is enhanced; after degradation is complete, the solenoid valve at the connection between the conveying pipe 204 and the biodegradation tank 2 is opened to discharge the degraded wastewater through the conveying pipe 204. During the degradation process, scale easily remains on the inner wall of the biodegradation tank 2. As the degraded wastewater is discharged, the pressure on the spring hose 202 gradually decreases, its elasticity recovers, and it drives the scraper 203 to move upward. During this process, the scale on the inner wall of the biodegradation tank 2 is scraped off and discharged by the solenoid drain valve 201. The discharged scale is collected by the waste collection tank 21, reducing pollution while improving the effect of reflux treatment. The conveying pipe 204 and the biofilm activity are enhanced. The filter screen installed at the connection of the degradation tank 2 filters impurities in the sewage during sewage transportation, improving sewage treatment efficiency. The bottom of the primary treatment tank 1 is equipped with a support frame 106, the other end of which is fixed to one side of the biodegradation tank 2 for fixing the primary treatment tank 1. The bottom of the circulating treatment tank 3 is equipped with multiple support columns 301 for fixing the circulating treatment tank 3. The sludge scraper 203 is made of waterproof and high-toughness material. The waterproof material greatly reduces the corrosive effect of sewage on the sludge scraper 203, and the high-toughness material reduces the damage caused by sewage impact on the sludge scraper 203, improving durability and reducing costs.

[0028] Second implementation method:

[0029] Figure 1 , Figure 4 and Figure 5This invention discloses a buried sewage treatment device with organic matter degradation function. Unlike the first embodiment, the other end of each conveying pipe 204 is connected to a sedimentation tank 4. A water supply pipe 401 is connected to the side wall of the sedimentation tank 4 for conveying the settled clear water. A filter screen is installed at the connection between the water supply pipe 401 and the sedimentation tank 4 for further filtration to improve sewage treatment efficiency. An expansion joint 402 is installed on the inner wall of the sedimentation tank 4. The output end of the expansion joint 402 is connected to a baffle 403 that cooperates with the water supply pipe 401. When the residual waste in the sewage settles and the clear water is discharged, the expansion joint 402 is controlled to contract, thereby opening the baffle 403 and collecting the waste into the bottom of the inner cavity of the sedimentation tank 4. The baffle 403 is made of waterproof and high-toughness material. The waterproof material greatly reduces the corrosive effect of sewage on the scraper 203, and the high-toughness material reduces the damage caused by sewage impact to the scraper 203, improving durability and reducing costs.

[0030] Please see Figure 1 and Figure 5 The other end of the water supply pipe 401 is connected to the purification tank 5. After filtration, the wastewater is transported to the purification tank 5 through the water supply pipe 401. A water purifier 501 is installed on the top of the purification tank 5. A high-pressure water purification pipe 502 is installed around the bottom of the water purifier 501. The high-pressure water purification pipe 502 is controlled by the water purifier 501 to purify the clean water. A clean water delivery pipe 503 is connected to the side wall of the purification tank 5. After purification, the clean water is transported out of the wastewater treatment equipment through the clean water delivery pipe 503.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
