[0015] A method for treating rural domestic sewage through resource utilization and treatment systems, characterized by comprising the following steps:

[0016] SS01: Domestic sewage is pumped by a water pump and introduced from the top of the sedimentation tank. The flow stabilizing mesh frame intercepts floating objects in the introduced domestic sewage through the interception net inside the tray. The domestic sewage located in the tray is guided downward through multiple water guide bends at the bottom center and introduced into the sedimentation tank from multiple water outlet ports on the periphery of the end of the water guide bends.

[0017] SS02: The domestic sewage located inside the sedimentation tank is discharged along the vortex guide plate. When the domestic sewage flows along the vortex guide plate, some of the mud and sand impurities in the domestic sewage settle to the bottom of the sedimentation tank and are discharged through the first sewage outlet. After sedimentation, the domestic sewage discharged along the vortex guide plate is introduced into the aeration box through the connecting pipe.

[0018] SS03: Two first servo motors drive the aeration mixing frame to rotate. When the two aeration mixing frames rotate relative to each other, domestic sewage flows through the water guide holes on the surface of the circular plate. When the circular plate rotates, it drives multiple spiral blades to rotate, causing the domestic sewage in the aeration box to turn from the outside to the inside. The aerator located at the inner end of the aeration box aerates the domestic sewage, forcibly introducing air into the domestic sewage, so that the domestic sewage in the aeration box comes into contact with the air and is oxygenated. The sewage is then introduced into the bottom treatment box from the water guide pipe at the bottom of the aeration box.

[0019] SS04: Wastewater discharged through the water guide pipe is forcibly added to the domestic sewage by an automatic dosing device. It gradually flows to the other end of the bottom treatment tank through multiple overflow baffles. Meanwhile, the second servo motor rotates and drives the flocculation mixing frame to rotate along multiple flocculation chambers. The stirring blades located in the multiple flocculation chambers enhance the flow of domestic sewage in the flocculation chambers under the operation of rotation, so that the flocculant can fully react with the domestic sewage and aggregate the colloids and suspended solids in the domestic sewage. The impurities that are partially precipitated in the flocculation chambers are discharged through the second sewage outlet.

[0020] SS05: Domestic sewage that has been flocculated in the flocculation chamber overflows into the sedimentation chamber. Some of the flocculated precipitates in the domestic sewage gradually settle downwards and collect at the bottom of the sedimentation chamber, and are discharged through the third sewage outlet.

[0021] SS06: After sedimentation in the sedimentation chamber, the domestic sewage flows upward between the top and bottom baffles. Multiple inclined plates located between the top and bottom baffles, along with intercepting baffles, stabilize the upward flow of domestic sewage, causing some of the coagulated matter in the domestic sewage to settle downward and collect at the bottom of the sedimentation chamber, and then be discharged through the third sewage outlet.

[0022] SS07: Domestic sewage that has been settled in the sedimentation chamber overflows into the clear water chamber through the bottom baffle and is discharged through the drain outlet. It can be used for farmland irrigation and other purposes.

[0023] The present invention has the following beneficial effects:

[0024] This invention integrates sedimentation, aeration, and flocculation into a single structural design, enabling efficient treatment of rural domestic sewage. It also features a small footprint and low operating costs. The flow stabilization mesh structure intercepts floating debris, while multiple water-guiding bends at the bottom of the basin stabilize the flow of sewage as it enters the sedimentation tank. Furthermore, the vortex-shaped guide plate guides the sewage within the sedimentation tank, reducing the impact of sewage flow on the sedimentation process and ensuring effective treatment of rural domestic sewage.

[0025] This invention improves the aeration effect of domestic sewage by having two aeration and stirring frames rotate relative to each other under the action of a first servo motor, and multiple spiral blades on the surface of the circular plate drive the sewage to tumble and stir. In addition, the structure design with multiple flocculation chambers and overflow flow can perform flocculation operation on domestic sewage online, thereby improving the treatment efficiency of rural domestic sewage.

[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] A method for treating rural domestic sewage through resource utilization includes the following steps:

[0041] SS01: Domestic sewage is pumped by a water pump and introduced from the top of the sedimentation tank 6. The flow stabilizing mesh frame 7 intercepts floating objects in the introduced domestic sewage through the interception net 703 inside the plate base 701. The domestic sewage located in the plate base 701 is guided downward through multiple water guide bends 704 at the bottom center and introduced into the sedimentation tank 6 from multiple water outlet ports 705 on the periphery of the end of the water guide bends 704.

[0042] SS02: The domestic sewage located inside the sedimentation tank 6 is discharged along the vortex guide plate 601. When the domestic sewage flows along the vortex guide plate 601, some of the mud and sand impurities in the domestic sewage settle to the bottom of the sedimentation tank 6 and are discharged through the first sewage outlet 603. After sedimentation, the domestic sewage discharged along the vortex guide plate 601 is introduced into the aeration box 4 through the connecting pipe 602.

[0043] SS03: Two first servo motors 8 drive the aeration mixing frame 5 to rotate respectively. When the two aeration mixing frames 5 rotate relative to each other, domestic sewage flows through the water guide holes 504 on the surface of the circular plate 502. When the circular plate 502 rotates, it drives multiple spiral blades 503 to rotate, causing the domestic sewage in the aeration box 4 to turn from the outside to the inside. The aerator 403 located at the inner end of the aeration box 4 aerates the domestic sewage and forces air into the domestic sewage, so that the domestic sewage in the aeration box 4 comes into contact with the air and is oxygenated. The sewage is then introduced into the bottom treatment box 1 from the bottom water guide pipe 401 at the bottom of the aeration box 4.

[0044] SS04: Wastewater discharged through the water guide pipe 401 is forcibly added to the domestic sewage by the automatic dosing device 402. It flows gradually to the other end of the bottom treatment tank 1 through multiple overflow baffles 101. The second servo motor 9 rotates and drives the flocculation stirring frame 2 to rotate along multiple flocculation chambers 102. The stirring blades in the multiple flocculation chambers 102 enhance the flow of domestic sewage in the flocculation chambers 102 under the operation of rotation, so that the flocculant can fully react with the domestic sewage and polymerize the colloids and suspended solids in the domestic sewage. The impurities that are partially precipitated in the flocculation chamber are discharged through the second sewage outlet 107.

[0045] SS05: The domestic sewage that has been flocculated in the flocculation chamber 102 overflows into the sedimentation chamber 105. Some of the flocculated precipitates in the domestic sewage gradually settle downwards and collect at the bottom of the sedimentation chamber 105, and are discharged through the third sewage outlet 108.

[0046] SS06: After sedimentation in the sedimentation chamber 105, the domestic sewage flows upward between the top baffle 103 and the bottom baffle 104. Multiple inclined plates 3 located between the top baffle 103 and the bottom baffle 104, together with the intercepting baffles 301, stabilize the upward flow of domestic sewage, causing some of the coagulated matter in the domestic sewage to settle downward and collect at the bottom of the sedimentation chamber 105, and then be discharged through the third sewage outlet 108.

[0047] SS07: Domestic sewage that has been settled in sedimentation chamber 105 overflows into clear water chamber 106 through bottom baffle 104 and is discharged through drain outlet 109. It can be used for farmland irrigation, etc.
