Specifically, the integrated device for treating domestic sewage in rural areas comprises a housing 1, a water inlet 7 and a water outlet 10 are arranged on both sides of the housing 1, and an anaerobic zone 2, an aerobic zone 3, a sedimentation zone 4, a sludge concentration zone 5 and a disinfection zone 6 are arranged in sequence between the water inlet 7 and the water outlet 10, and the functions of each zone are clear, so as to realize the harmless treatment and resource utilization of domestic sewage. Among them, the anaerobic zone 2 is arranged at the water inlet 7 of the housing 1, and is used to treat the domestic sewage anaerobically, so as to realize the decomposition of organic matter and the recovery of energy. The aerobic zone 3 is arranged at the rear of the anaerobic zone 2, and is used to further treat the domestic sewage after anaerobically treatment, and further remove organic matter and nutrients such as nitrogen and phosphorus. The sedimentation zone 4 is arranged at the rear of the aerobic zone 3, and is used to precipitate the domestic sewage treated by the aerobic zone 3, so as to realize solid-liquid separation. The sludge concentration zone 5 is arranged at the rear of the sedimentation zone 4, and is used to separate the sludge and water precipitated in the sedimentation zone 4, so as to realize the reduction and stabilization of the sludge. The disinfection area 6 is arranged behind the sludge concentration area 5, and is used to disinfect and sterilize the water after being treated in the sludge concentration area 5 and discharge the treated water. The disinfection and sterilization treatment ensures the safety of the effluent water quality. In addition, the device realizes the harmless treatment and resource utilization of domestic sewage through the orderly arrangement and treatment of each area, and has the advantages of high efficiency, stability, energy saving and environmental protection.

[0020] refer to Figure 1As shown, there are pipes 9 interconnecting the anaerobic zone 2, the aerobic zone 3, the sedimentation zone 4, the sludge concentration zone 5 and the disinfection zone 6. Specifically, the integrated rural domestic sewage treatment device realizes the connection between the zones by setting pipes 9 between the treatment zones. This design helps to ensure that domestic sewage flows smoothly between the treatment zones and avoids blockage or interruption of the treatment process. The connection between the anaerobic zone 2, the aerobic zone 3, the sedimentation zone 4, the sludge concentration zone 5 and the disinfection zone 6 helps to ensure that the sewage can smoothly enter the next treatment zone after passing through one treatment zone. This design helps to improve the treatment efficiency of the entire device and ensure that domestic sewage is fully and effectively treated. In addition, the interconnected design also helps to achieve synergy between the treatment zones. For example, by-products such as biogas produced during the anaerobic treatment process can be transported to other treatment zones through pipelines to improve the environmental conditions of other treatment zones or to be recycled as energy. Such a design can further improve the resource utilization efficiency and environmental performance of the entire device.

[0021] refer to Figure 1 As shown, the anaerobic zone 2 includes a filter screen 2a arranged at the water inlet 7, an anaerobic filler 2b is arranged behind the filter screen 2a, and a biogas collector 2c is arranged above the anaerobic filler 2b. Specifically, the design of adding the filter screen 2a, the anaerobic filler 2b and the biogas collector 2c in the anaerobic zone 2 further improves the function and efficiency of the integrated device. The filter screen 2a can intercept large particles of impurities and protect the subsequent anaerobic treatment area from being blocked by large particles of impurities. The anaerobic filler 2b provides a medium for anaerobic bacteria to attach and grow. The anaerobic filler 2b can increase the contact area between anaerobic microorganisms and wastewater and improve the efficiency of anaerobic treatment. The biogas collector 2c can collect biogas generated during the anaerobic treatment process. Biogas is a combustible gas that can be used for energy recovery, such as heating or power generation. At the same time, the collection of biogas also helps to improve the environmental performance of the entire device and reduce greenhouse gas emissions. Through these improved designs, the anaerobic zone 2 not only improves the treatment efficiency of domestic sewage, but also realizes the recycling of biogas, further improving the resource utilization efficiency and environmental performance of the entire device. Such a design is of great significance for promoting the advancement and sustainable development of rural domestic sewage treatment technology.

[0022] refer to Figure 1As shown, the aerobic zone 3 includes an MBBR filler 3a arranged inside it, and an aeration device 3b is arranged below the MBBR filler 3a. Specifically, the design of adding MBBR filler 3a and aeration device 3b in the aerobic zone 3 further improves the treatment effect and efficiency of the integrated device. MBBR filler 3a is a moving bed bioreactor technology. By arranging MBBR filler 3a in the aerobic zone 3, the concentration and activity of the organisms can be increased, and the removal efficiency of organic matter can be improved. At the same time, the MBBR filler 3a moves continuously in the reactor, which increases the contact time between the organisms and the wastewater, which helps to improve the treatment effect. The aeration device 3b provides sufficient dissolved oxygen for aerobic treatment to ensure the growth and metabolism of aerobic microorganisms. Through the reasonable arrangement and adjustment of the aeration device 3b, the mixing and oxygenation effect of the aerobic zone can be optimized, and the removal efficiency of organic matter can be improved. Through these improved designs, the treatment effect of the aerobic zone 3 is significantly improved, ensuring that domestic sewage is fully and effectively treated. At the same time, these designs also help to improve the stability and reliability of the entire device and ensure good performance in long-term operation. Such a design is of great significance for improving the capacity and level of rural domestic sewage treatment.

[0023] refer to Figure 1 As shown, the sedimentation zone 4 includes a sludge hopper 4a arranged at the bottom of the sedimentation zone 4. Specifically, the design of adding the sludge hopper 4a in the sedimentation zone 4 is helpful to better handle and dispose of the precipitated sludge. The sludge hopper 4a can effectively collect and store the precipitated sludge. By regularly discharging the sludge in the sludge hopper 4a, the smooth operation of the sedimentation zone 4 can be ensured to avoid the accumulation and blockage of sludge. The collected sludge can be properly treated and disposed. For example, the sludge can be dehydrated, stabilized or bio-utilized to achieve resource recovery and reuse. Through such a design, the treatment effect of the sedimentation zone 4 is further optimized, and it also helps to reduce the burden of subsequent sludge treatment. Such a design helps to improve the environmental performance and sustainability of the entire device.

[0024] refer to Figure 1As shown, the sludge concentration zone 5 includes a sludge feed pump 5a connected to the sludge hopper 4a, and the output end of the sludge feed pump 5a is connected to a concentrating device 5b. Specifically, the design of adding the sludge feed pump 5a and the concentrating device 5b in the sludge concentration zone 5 helps to more efficiently treat and concentrate the precipitated sludge. The sludge feed pump 5a can effectively transport the precipitated sludge to the concentrating device 5b. The selection of the sludge feed pump 5a should ensure sufficient conveying capacity and pressure to meet the needs of the concentrating device 5b. The concentrating device 5b can concentrate the input sludge, remove excess water, and effectively reduce and stabilize the sludge. Common concentrating devices include gravity concentrating tanks, mechanical concentrators, etc. Through such a design, the sludge treatment process is smoother and the treatment efficiency of the entire device is improved. At the same time, such a design also helps to reduce the burden of subsequent sludge disposal and achieve effective recovery and reuse of resources. Such a design helps to improve the environmental performance and sustainability of the entire device.

[0025] refer to Figure 1 As shown, the disinfection area 6 includes a chlorination treatment device 6a installed inside it, and an ultraviolet disinfector 6b is installed above the chlorination treatment device 6a. Specifically, the design of adding the chlorination treatment device 6a and the ultraviolet disinfector 6b in the disinfection area 6 helps to further ensure the safety and harmlessness of the water quality of the effluent. The chlorination treatment device 6a is a commonly used disinfection method. By adding chlorine or chlorides to the water, bacteria, viruses and other microorganisms in the water can be effectively killed. The design of the chlorination treatment device should ensure the uniform addition of chlorine or chlorides, and control the addition amount to meet the disinfection requirements and avoid the generation of by-products such as residual chlorine. The ultraviolet disinfector 6b is a physical disinfection method that destroys the DNA structure of microorganisms through ultraviolet irradiation, so that they lose their reproductive ability and achieve the purpose of disinfection. Ultraviolet disinfection has the advantages of high efficiency and no secondary pollution, and is suitable for the final disinfection of the effluent. Through such a design, the treatment effect of the disinfection area 6 is further enhanced, ensuring that the effluent water quality meets the discharge standard or reuse requirements. Such a design also helps to improve the reliability and stability of the entire device and ensure good performance in long-term operation. Such a design is of great significance for improving the capacity and level of rural domestic sewage treatment.

[0026] refer to Figure 1As shown, a solar panel 11 is installed on the top of the box 1. Specifically, installing the solar panel 11 on the top of the box 1 helps to convert solar energy into electrical energy and provide part of the energy for the entire device. The solar panel 11 can be automatically adjusted or manually adjusted according to the angle and intensity of the sunlight to maximize the absorption and conversion efficiency of solar energy. The converted electrical energy can be used to drive pumps, aeration devices 3b, agitators and other equipment in the device, reducing dependence on traditional electricity and saving energy costs. Such a design helps to improve the sustainability and environmental performance of the entire device, reduce dependence on traditional energy, and reduce operating costs. At the same time, the installation of the solar panel 11 also helps to improve the aesthetics and integration of the device, making it more adaptable to the rural environment.
