Description

Technical Field

[0001] This invention relates to the field of rural domestic sewage treatment technology, specifically to an integrated rural domestic sewage treatment equipment. Background Technology

[0002] Rural domestic sewage refers to wastewater generated during residential life. The main technologies are divided into two categories: natural treatment systems and biological treatment systems. Natural treatment systems achieve purification through soil, plants, and microorganisms, while biological treatment systems include aerobic and anaerobic biological treatment processes. Common methods include constructed wetlands and soil infiltration purification. Existing rural domestic sewage treatment equipment mostly adopts a simple direct dosing mode. The water in the sedimentation tank has poor flow and the sewage is almost stagnant. After the flocculant is added, it cannot spread and mix quickly, and it is easy for the flocculant to accumulate locally. It is difficult to fully capture the fine suspended impurities in the water. The generated flocs are loose, small in size, and have poor settling performance. Ultimately, the solid-liquid separation effect of the sedimentation tank is not good, which affects the purification effect of rural domestic sewage. Summary of the Invention

Multiple ultraviolet lamps are provided, and the multiple ultraviolet lamps are arranged in a circle around the disinfection tank.

[0014] The present invention has the following beneficial effects: This invention's wastewater treatment component comprises a series of multiple tanks connected in series: an equalization tank, an anaerobic tank, an anoxic tank, an aerobic tank, a sedimentation tank, and a disinfection tank. It is further equipped with a perforated baffle plate, a distribution pipe, a circular pipe, an overflow rack, a baffle overflow rack, a fixed pipe overflow rack, a sludge discharge device, a sludge pump, a transfer pump, an inlet pipe, a sealing cover, and a discharge pipe, forming a complete A² / O treatment process. The perforated baffle plate inside the equalization tank buffers the impact of intermittent rural wastewater discharge on water volume and quality, ensuring homogeneous and balanced water intake. The inlet of the transfer pump is located on the side of the equalization tank near the anaerobic tank, stably drawing homogeneous water and protecting the stable survival of the downstream biological bacteria. Inside the anaerobic tank, a circular pipe connecting to the outlet of the transfer pump, along with symmetrically arranged distribution pipes, distributes water at multiple points, continuously flushing the tank. To prevent sludge accumulation, the hinged sealing cover at the top of the anaerobic tank maintains a closed anaerobic environment, fully completing the anaerobic hydrolysis of macromolecular pollutants and reducing the load on subsequent treatments. The anaerobic, anoxic, and aerobic tanks rely on overflow racks one, two, and three to achieve stratified gravity flow. The bottom of the baffles inside the aerobic tank and the bottom of the tank are reserved with a gap to extend the water flow path and accurately distinguish between the three reaction environments of anaerobic, anoxic, and aerobic, achieving complete denitrification and phosphorus removal, and efficiently degrading COD, ammonia nitrogen, and total phosphorus. The sedimentation tank relies on overflow rack four to achieve stable overflow of the upper clear liquid. The sludge discharge device at the bottom of the sedimentation tank, together with the sludge pump, continuously pumps out the settled sludge to prevent sludge from floating and causing turbidity in the effluent. The supernatant in the sedimentation tank finally flows into the disinfection tank to complete the final deep purification.

[0015] This invention's aeration component uses a blower as the core air source, working in conjunction with a control valve, a bend-pipe check valve, and an aeration pipe / air outlet pipe. Air produced by the blower is delivered via the control valve, bend-pipe check valve, and air outlet pipe to the aeration pipe at the bottom of the aerobic tank. Multiple air outlet pipes are symmetrically arranged on the surface of the aeration pipe, continuously releasing gas upwards, creating a uniform aeration environment throughout the aerobic tank with no oxygen dead zones. This continuously provides sufficient dissolved oxygen for aerobic microorganisms, significantly improving the degradation efficiency of organic pollutants. The check valve in the middle of the pipeline prevents sewage from backflowing into the blower, avoiding water ingress and corrosion damage to the aeration power equipment, and extending the overall service life of the machine. A transfer pipe connected to the side of the control valve enables air source diversion. A single blower can supply oxygen to the aerobic tank and also provide turbulent airflow to the sedimentation tank / disinfection tank, reducing the construction cost and power consumption of rural sewage treatment plants.

[0016] The auxiliary components of this invention include a transfer pipe, a dosing device, a control valve, a one-way valve, a dosing pipe, a rectangular tube, a central frame, a side pipe, and swirl fan blades. Utilizing a blower-driven air supply and a flocculant dosing system, the solid-liquid separation effect of the sedimentation tank is enhanced. The dosing device, installed on the top of the bottom plate, delivers flocculant to the central frame above the sedimentation tank via a dosing pipe. Wastewater transported through a fixed pipe inside the sedimentation tank simultaneously flows into the central frame. The flocculant and wastewater flow together into the side pipe. The water flow impacts the swirl fan blades fixed to the inner wall of the side pipe, automatically creating forced swirling agitation. This allows the flocculant to fully contact and fuse with the fine suspended solids in the wastewater, rapidly generating dense, large flocs, reducing the amount of flocculant used and improving flocculation and sedimentation efficiency. The airflow from the transfer pipe passes through the one-way valve and enters the rectangular tube at the bottom of the sedimentation tank, continuously releasing micro-airflow. This slightly disturbs the water in the tank, preventing floc compaction and sludge accumulation in dead corners, extending the equipment's sludge removal cycle, and also driving water flow, allowing incompletely aggregated small particles to be continuously captured and flocculated, further reducing suspended solids and turbidity in the effluent.

[0017] The sterilization component of this invention consists of an installation pipe, a bottom pipe, an annular pipe, an auxiliary pipe, a quartz glass sleeve, an ultraviolet lamp support ring, and a dosing device. It employs a triple-synergistic sterilization mode combining airflow disturbance, ultraviolet disinfection, and chemical oxidation. Gas from the transfer pipe flows into the installation pipe via a control valve, then is delivered to the bottom pipe via a one-way valve. The bottom pipe extends into the disinfection tank and connects to the annular pipe. Multiple auxiliary pipes are connected to the inner ring of the annular pipe, releasing airflow from the bottom of the disinfection tank in all directions to continuously circulate the water, solving the problem of blind spots in static water sterilization and ensuring that all wastewater passes through the ultraviolet irradiation area. Multiple ultraviolet lamps are arranged in a circular pattern around the disinfection tank. The system consists of a cloth and an external quartz glass sleeve. An ultraviolet lamp is fixed to the surface of the disinfection tank via a support ring. The quartz glass sleeve isolates the water and reduces scale buildup. The long-term, stable output of ultraviolet light destroys the genetic material of bacteria and microorganisms, achieving physical sterilization. A dosing device at the top of the tank allows for the addition of sodium hypochlorite disinfectant, which uses chemical oxidation to kill residual ultraviolet bacteria. This complementary combination of physical and chemical disinfection methods significantly improves the removal rate of fecal coliform pathogens, ensuring stable compliance of effluent microbial indicators. A one-way valve in the pipeline prevents backflow of water into the disinfection tank, protects the upstream fan pipeline, and enhances the stability of equipment operation.

[0033] In operation, rural domestic sewage enters the equalization tank 10 through the inlet pipe 11. Multiple porous baffles 12 are installed inside the equalization tank 10 to buffer the sewage and reduce its impact. The transfer pump 20 is then started, transporting the sewage from the equalization tank 10 to the anaerobic tank 13 for anaerobic treatment. Anaerobic bacteria ferment the sewage, breaking down grease, large organic molecules, and recalcitrant pollutants into smaller, biodegradable substances. To reduce the treatment pressure in the subsequent aerobic tank, a circular pipe 23 and a diversion pipe 22 are installed at the output end of the transfer pump 20. Rural domestic sewage is discharged through the circular pipe 23 and the diversion pipe 22. The surface of the diversion pipe 22 is provided with multiple discharge holes, thereby using the circular pipe 23 and the diversion pipe 22 to flush the bottom of the inner wall of the anaerobic tank 13, preventing impurities in the rural domestic sewage from accumulating inside the anaerobic tank 13. When the rural domestic sewage inside the anaerobic tank 13 reaches a certain water level, the rural domestic sewage will enter the overflow rack 24, which will then be used to flush the wastewater. Rural domestic sewage is transported to the anoxic tank 15 for anoxic treatment. Once the sewage reaches a certain level in the anoxic tank 15, it flows into the overflow rack 25 and then into the aerobic tank 16 for aerobic treatment, thus purifying the sewage. When the sewage in the aerobic tank 16 reaches a certain level, it flows into the sedimentation tank 17 through the overflow rack 27. In the sedimentation treatment, impurities in rural domestic sewage will settle inside the sedimentation tank 17. A sludge discharge device 30 is installed at the bottom of the sedimentation tank 17 to discharge the settled impurities. The sludge pump 19 will transport the impurities discharged by the sludge discharge device 30 for centralized treatment. When the rural domestic sewage in the sedimentation tank 17 reaches a certain water level, the rural domestic sewage will enter the disinfection tank 18 through the overflow rack 29 for disinfection treatment, thereby completing the purification treatment of rural domestic sewage. After rural domestic sewage enters the aerobic tank 16, the blower 40 is started to operate. During operation, the blower 40 transmits gas to the aeration pipe 44 through the bend pipe 42. The gas enters the rural domestic sewage through the aeration pipe 44 and the air outlet pipe 45 to aerate the rural domestic sewage. A one-way valve 43 is installed at the end of the aeration pipe 44 to prevent the rural domestic sewage in the aerobic tank 16 from flowing back into the blower 40. The aeration pipe 44 and the air outlet pipe 45 are used to continuously oxygenate the interior of the aerobic tank 16, and the aerobic bacteria are used to degrade the rural domestic sewage, thereby achieving the purification treatment of rural domestic sewage. When rural domestic sewage in aerobic tank 16 flows into sedimentation tank 17 through fixed pipe 28, dosing device 51 is activated. Dosing device 51 adds flocculant to collection rack 56 through dosing pipe 54. Rural domestic sewage also enters collection rack 56 through fixed pipe 28, thus mixing with flocculant. Rural domestic sewage and flocculant then enter sedimentation tank 17 through side pipe 57. Swirl fan blades 58 are installed inside side pipe 57. The rural domestic sewage and flocculant flow within side pipe 57... When the pump is in motion, it impacts the swirl fan blades 58, thereby mixing the domestic sewage and flocculant together and improving the mixing effect. The flocculant is used to separate and treat the fine impurities in the domestic sewage. The blower 40 is connected to the transfer pipe 50 through the control valve 41. The transfer pipe 50 transmits the gas to the rectangular pipe 55. The gas is discharged into the sedimentation tank 17 through the rectangular pipe 55. After the gas enters the sedimentation tank 17, it impacts the domestic sewage and flows inside the sedimentation tank 17, further improving the mixing effect of the domestic sewage and flocculant. After sedimentation, the rural domestic sewage enters the disinfection tank 18. The ultraviolet lamp 62 in the quartz glass sleeve 61 performs ultraviolet sterilization on the rural domestic sewage. At this time, the transfer pipe 50 is connected to the bottom pipe 65 by the control valve 2 52. The gas in the transfer pipe 50 is transmitted to the ring pipe 63 through the bottom pipe 65. The ring pipe 63 and the auxiliary pipe 64 discharge the gas into the disinfection tank 18. The gas impacts the rural domestic sewage in the disinfection tank 18, causing the rural domestic sewage to flow in the disinfection tank 18, which improves the sterilization effect of the ultraviolet lamp 62 on the rural domestic sewage. The dosing device 2 60 adds sodium hypochlorite to the disinfection tank 18 to kill the bacteria in the sodium hypochlorite and improve the purification effect of the rural domestic sewage.
