Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to an integrated treatment system for domestic wastewater. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards in my country, the discharge of domestic sewage is increasing day by day, putting increasing pressure on the water environment. However, my country has a vast territory and significant differences in economic development levels among different regions, resulting in an imbalance in the construction and development of domestic sewage treatment facilities. The sewage treatment rate in developed coastal cities is much higher than that in inland provinces, and the problem of domestic sewage treatment is particularly prominent in rural areas.

[0003] The invention disclosed in CN119430493A, entitled "A High-Concentration Ammonia Nitrogen Rural Domestic Sewage Treatment System," includes an equalization tank, basic sewage treatment equipment connected to the equalization tank, and sequentially connected anaerobic, an anoxic, aerobic, and sedimentation tanks. A first sludge return pipe connects the anaerobic and sedimentation tanks, and a second sludge return pipe connects the aerobic and anoxic tanks. A first driving source is installed on the first sludge return pipe, and a second driving source is installed on the second sludge return pipe. The first driving source is used for driving... The system involves two main components: a first sludge return pipe to drive fluid flow into the anaerobic tank, and a second drive source to drive fluid flow into the anoxic tank via the second sludge return pipe. A wastewater enhancement treatment system, connected between the basic wastewater treatment equipment and the equalization tank, includes a biological treatment tank, an aerobic tank, and an anoxic tank within the biological treatment tank, all interconnected. An aeration system is used to aerate the anoxic tank, aerobic tank, anoxic tank, and aerobic tank. A bacterial inactivation system is used to inactivate nitrifying bacteria within the second sludge return pipe. While this system improves the stability of wastewater treatment, the aforementioned high-concentration ammonia nitrogen rural domestic wastewater treatment system still suffers from a lack of compactness, resulting in a large footprint.

[0030] This utility model discloses an integrated treatment system for domestic sewage. It integrates an anaerobic unit, an aerobic unit, a sedimentation unit, and a disinfection unit. When domestic sewage needs treatment, it is transported to the anaerobic unit. Under anaerobic conditions, anaerobic microorganisms in the anaerobic unit hydrolyze and acidify pollutants in the sewage, decomposing large organic molecules. The sewage, after anaerobic treatment, is then discharged to the aerobic unit. Under sufficient oxygen conditions, aerobic microorganisms in the aerobic unit utilize oxygen to oxidize organic matter, ammonia nitrogen, and nitrates in the sewage, ultimately producing water and nitrogen. The synergistic cooperation of the anaerobic and aerobic units achieves efficient degradation and removal of organic matter and pollutants such as nitrogen and phosphorus in the sewage. The sewage, after aerobic treatment, is then transported to the sedimentation unit, where it settles to separate sewage from sludge. Finally, the sewage, after sedimentation treatment, is discharged. The wastewater is disinfected within the disinfection unit. After disinfection, the wastewater meets discharge standards and can be discharged to the outside through the outlet of the disinfection unit. The anaerobic, aerobic, and disinfection units are arranged around the sedimentation unit, resulting in a compact layout that effectively utilizes space and reduces floor space, making it particularly suitable for situations with limited space. Furthermore, it shortens the water flow transmission distance, reducing the length of connecting pipes between units and thus lowering energy consumption and operating costs. The shorter transmission distance also reduces hydraulic retention time, contributing to improved overall treatment efficiency. The centralized arrangement of the units facilitates monitoring and maintenance by operators, reducing inspection time. Additionally, the compact layout reduces civil engineering work, saving construction costs. Finally, the centralized arrangement makes the integrated treatment system neater and more aesthetically pleasing.

[0036] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0037] See Figure 1 This invention illustrates a preferred embodiment of an integrated treatment system for domestic sewage, comprising:

[0038] Anaerobic device 1, the inlet of anaerobic device 1 is used to connect with an external domestic sewage treatment device (not shown in the figure), and anaerobic device 1 is used to hydrolyze and acidify pollutants in domestic sewage.

[0039] Aerobic device 2, the inlet of aerobic device 2 is connected to the outlet of anaerobic device 1, aerobic device 2 is used to degrade organic matter in wastewater treated by anaerobic device 1.

[0040] Sedimentation device 3, with its inlet connected to the outlet of aerobic device 2, is used to settle the wastewater treated by aerobic device 2 to separate the wastewater from the sludge; and

[0041] Disinfection device 4, the inlet of disinfection device 4 is connected to the outlet of sedimentation device 3, disinfection device 4 is used to disinfect the sewage output from sedimentation device 3, and the outlet of disinfection device 4 is used to output the disinfected water.

[0042] Among them, the anaerobic device 1, the aerobic device 2 and the disinfection device 4 are arranged around the sedimentation device 3.

[0043] This utility model discloses an integrated treatment system for domestic sewage. It integrates an anaerobic unit 1, an aerobic unit 2, a sedimentation unit 3, and a disinfection unit 4. When domestic sewage needs treatment, it is transported to the anaerobic unit 1. Under anaerobic conditions, anaerobic microorganisms within the anaerobic unit 1 hydrolyze and acidify pollutants in the sewage, decomposing large organic molecules. The sewage treated by the anaerobic unit 1 is then discharged to the aerobic unit 2. Under sufficient oxygen conditions, aerobic microorganisms in the aerobic unit 2 utilize oxygen to oxidize organic matter, ammonia nitrogen, and nitrates in the sewage, ultimately producing water and nitrogen. The synergistic cooperation of the anaerobic unit 1 and the aerobic unit 2 enables efficient degradation and removal of organic matter and pollutants such as nitrogen and phosphorus from the sewage. The sewage treated by the aerobic unit 2 is then transported to the sedimentation unit 3, where it settles to separate sewage from sludge. Finally, the sewage treated by the sedimentation unit 3 is discharged. The wastewater is then disinfected within the disinfection device 4. After disinfection, the wastewater meets discharge standards and can be discharged to the outside through the outlet of the disinfection device 4. The anaerobic device 1, aerobic device 2, and disinfection device 4 are arranged around the sedimentation device 3, resulting in a compact layout that effectively utilizes space and reduces floor space, making it particularly suitable for situations with limited space. Furthermore, it shortens the water flow transmission distance, reducing the length of connecting pipes between devices and thus lowering energy consumption and operating costs. Shorter transmission distances also reduce hydraulic retention time, contributing to improved overall treatment efficiency. The centralized arrangement of the devices facilitates monitoring and maintenance by operators, reducing inspection time. The compact layout also reduces civil engineering work, saving construction costs. Finally, the centralized arrangement makes the integrated treatment system neater and more aesthetically pleasing.

[0044] In one embodiment, the anaerobic device 1 has an anaerobic chamber that connects to an external domestic sewage treatment plant and an aerobic device 2. The anaerobic chamber contains an anaerobic sludge bed and anaerobic microorganisms located on the anaerobic sludge bed.

[0045] In one embodiment, the aerobic device 2 has an aerobic chamber that connects to the anaerobic device 1 and the sedimentation device 3. The aerobic chamber contains an aerobic sludge bed and aerobic microorganisms located on the aerobic sludge bed.

[0046] In one embodiment, the sedimentation device 3 has a sedimentation chamber that is connected to the aerobic device 2 and the disinfection device 4. The sedimentation chamber is used to allow the wastewater that has been degraded by the aerobic device 2 to settle and separate the wastewater from the sludge.

[0047] In one embodiment, the disinfection device 4 has a disinfection chamber connected to the sedimentation device 3, and the disinfection chamber is used to mix the wastewater output from the sedimentation device 3 with disinfectant water (such as sodium hypochlorite water).

[0048] See Figure 1 In one embodiment, the integrated treatment system for domestic sewage further includes:

[0049] The inlet of the inlet regulating device 5 is connected to the external domestic sewage device, and the outlet of the inlet regulating device 5 is connected to the inlet of the anaerobic device 1. The inlet regulating device 5 is used to mix domestic sewage from different sources, so that the domestic sewage from different sources is fully mixed, which plays a role in balancing water quality and improving the hydrolysis and acidification efficiency of the anaerobic device 1 for domestic sewage.

[0050] See Figure 1 In one embodiment, the inlet regulating device 5 is provided with an inlet regulating chamber 52 and a baffle 53. The inlet regulating chamber 52 is connected to the inlet of the external domestic sewage device and the anoxic device 1. The baffle 53 is used to extend the residence time of domestic sewage in the inlet regulating chamber 52, so that domestic sewage from different sources is mixed evenly in the inlet regulating chamber 52 to improve the water quality balance effect.

[0051] See Figure 1 In one embodiment, the partition 53 is located between the inlet 51 of the water inlet regulating device and the outlet of the water inlet regulating device 5. The partition 53 divides the water inlet regulating chamber 52 into at least two sub-inlet sections 521. The inlet and outlet of the sub-inlet section 521 are located at opposite ends of the length of the sub-inlet section 521.

[0052] In two adjacent sub-inlet sections 521, the inlet of one sub-inlet section 521 is connected to the inlet 51 of the inlet regulating device, and the outlet of the sub-inlet section 521 is connected to the inlet of the other sub-inlet section 521. The outlet of the other sub-inlet section 521 is connected to the outlet of the inlet regulating device 5. In this way, after the domestic sewage output from the domestic sewage treatment device enters the inlet regulating device 5, the domestic sewage flows along the sub-inlet section 521 closest to the inlet 51 of the inlet regulating device until it flows to the next sub-inlet section 521, and then flows along the sub-inlet section 521 to the anoxic device 1. This increases the flow time of domestic sewage in the inlet regulating device 5, which is conducive to the uniform mixing of domestic sewage from different sources, thereby playing a role in balancing water quality.

[0053] See Figure 1 In this embodiment, there are two partitions 53, which are staggered to further increase the flow time of domestic sewage in the inlet regulating device 5, so that domestic sewage from different sources is mixed more evenly.

[0054] In other embodiments, the inlet regulating chamber 52 is divided into at least two sub-inlet sections 521 by a partition 53. The partition 53 has multiple water passages, which are spaced apart and connect two adjacent sub-inlet sections 521. This can also prolong the residence time of domestic sewage in the inlet regulating chamber 52, so that domestic sewage from different sources is mixed evenly in the inlet regulating chamber 52, thereby improving the water quality balance.

[0055] In other embodiments, the partition 53 divides the inlet regulating chamber 52 into at least two sub-inlet sections 521. A water passage gap is left at the bottom of the partition 53 and the inlet regulating chamber 52. In this way, the residence time of domestic sewage in the inlet regulating chamber 52 can also be extended, so that domestic sewage from different sources can be mixed evenly in the inlet regulating chamber 52, thereby improving the water quality balance effect.

[0056] See Figure 1 In one embodiment, the integrated treatment system for domestic sewage further includes:

[0057] 6. Sludge storage device;

[0058] The sludge conveyor 7 has its inlet connected to the sedimentation device 3 via the inlet pipe 8, and its outlet connected to the sludge storage device 6 via the outlet pipe 9. The sludge conveyor 7 is used to transport the sludge in the sedimentation device 3 to the sludge storage device 6, so as to realize the timely output of the sludge in the sedimentation device 3 to the sludge storage device 6 for storage, and ensure that the sedimentation device 3 can separate the sludge from the wastewater.

[0059] In this embodiment, the sludge conveyor 7 can be a pump, which can be used to smoothly and reliably transport the sludge in the sedimentation device 3 to the sludge storage device 6. At the same time, the pump has the advantages of stable operation, low failure rate and low maintenance cost, which can improve the operational stability and operating cost of the integrated treatment system.

[0060] Of course, in other embodiments, the sludge conveyor 7 can also be a structure such as an ejector, a siphon, or a screw conveyor.

[0061] See Figure 1 In one embodiment, the integrated treatment system for domestic sewage further includes:

[0062] The medicine storage container 10 is used to store disinfectant (such as sodium hypochlorite solution);

[0063] The dosing conveyor 20 has its inlet connected to the storage container 10 and its outlet connected to the disinfection device 4 via the dosing pipe 30. The dosing conveyor 20 is used to transport the disinfectant solution in the storage container 10 to the disinfection device 4 so that the sewage in the disinfection device 4 can be mixed with the disinfectant solution to achieve disinfection treatment of the sewage.

[0064] In this embodiment, the dosing delivery device 20 can be a pump, which can smoothly and reliably deliver the disinfectant in the storage container 10 to the disinfection device 4, ensuring that the sewage in the disinfection device 4 is disinfected. At the same time, the pump has the advantages of stable operation, low failure rate and low maintenance cost, which can improve the operational stability and operating cost of the integrated treatment system.

[0065] Of course, in other embodiments, the dosing delivery device 20 can also be a structure such as an injector, a siphon, or a screw conveyor.

[0066] See Figure 1 In one embodiment, the integrated treatment system for domestic sewage further includes:

[0067] Aeration blower 40, the inlet of which is used to connect with the outside atmosphere;

[0068] Aerator 50 has its inlet connected to the outlet of aeration blower 40, and its outlet connected to aerobic device 2. Aerator 50 is specifically located at the bottom of the aerobic chamber of aerobic device 2. Since aeration blower 40 is connected to the outside atmosphere, air from the outside atmosphere can be transported to aerator 50 through a pipe. Aerator 50 disperses the air into tiny bubbles, increasing the gas-liquid contact area. As the bubbles rise, oxygen is transferred from the bubbles to the wastewater, providing oxygen for microorganisms to degrade organic matter. Furthermore, the rising bubbles can drive water flow, promoting mixing and preventing sludge sedimentation. Therefore, the combined use of aeration blower 40 and aerator 50 achieves efficient oxygenation, uniform mixing, stable operation, and energy conservation and environmental protection.

[0069] See Figure 1 In one embodiment, the integrated treatment system for domestic sewage further includes:

[0070] The equipment storage device 60 houses the sludge conveyor 7, chemical storage container 10, chemical dosing conveyor 20, and aeration fan 40. This centralized arrangement reduces the occupied area, making the overall structure of the integrated treatment system more compact and requiring less space. Furthermore, centralized management of all equipment facilitates maintenance and repair, improving work efficiency. Additionally, centralized storage avoids clutter and enhances the overall aesthetics. The integrated design simplifies transportation and installation processes, saving time and costs. Finally, centralized equipment management facilitates monitoring and troubleshooting, improving system stability.

[0071] See Figure 1 In one embodiment, the influent regulating device 5, the anoxic device 1, the aerobic device 2, the equipment storage device 60, the sludge storage device 6, and the disinfection device 4 are arranged in sequence around the sedimentation device 3. Because the influent regulating device 5, the anoxic device 1, the aerobic device 2, the equipment storage device 60, the sludge storage device 6, and the disinfection device 4 are arranged around the sedimentation device 3, the influent regulating device 5, the anoxic device 1, the aerobic device 2, the equipment storage device 60, the sludge storage device 6, the disinfection device 4, and the sedimentation device 3 are centrally located. This compact arrangement effectively utilizes space and reduces the floor space required, making it particularly suitable for situations with limited space. Furthermore, it shortens the water flow transmission distance, reducing the length of connecting pipes between devices, thereby reducing energy consumption and operating costs. Shorter transmission distances also reduce hydraulic residence time, contributing to improved overall treatment efficiency. The centralized arrangement of the devices facilitates monitoring and maintenance by operators, reducing inspection time. Additionally, the compact layout reduces civil engineering work, saving construction costs. Finally, the centralized arrangement makes the integrated treatment system neater and more aesthetically pleasing.

[0072] In one embodiment, the influent regulating device 5, the anoxic device 1, the aerobic device 2, the equipment storage device 60, the sludge storage device 6, and the disinfection device 4 are connected sequentially end to end. Furthermore, the influent regulating device 5, the anoxic device 1, the aerobic device 2, the equipment storage device 60, the sludge storage device 6, and the disinfection device 4 are all connected to the sedimentation device 3. This allows the integrated treatment system to form a modular structure, enabling it to be used immediately upon installation, thus improving ease of use and installation efficiency.

[0073] See Figure 1 In one embodiment, the integrated treatment system for domestic sewage further includes:

[0074] A stirrer 70 is installed in the anaerobic device 1. The stirrer 70 is used to stir the sewage in the anaerobic device 1 to improve the water quality balance and improve the hydrolysis and acidification efficiency of the anaerobic device 1 for pollutants in the sewage.
