[0033] Embodiment: A novel horizontal sewage separation device, as shown in the attached Figure 1 As shown, it includes a tank body 1 and a top cover 2; the utility model adopts a taper design for the tank body 1 and the top cover 2, respectively, the cross section of the joint of the tank body 1 and the top cover 2 is larger, and the cross section of the bottom end of the tank body 1 and the top of the top cover 2 is smaller. The utility model also provides a bottom reinforcement protrusion 11 and a top reinforcement protrusion 21 on the side walls of the tank body 1 and the top cover 2, respectively, and such protrusions are used as reinforcing ribs to improve the overall strength of the tank body 1 and the top cover 2. Those skilled in the art can also design such protrusions into grooves, which can play the same reinforcing role, but in actual application, such groove design may affect the water storage capacity of sewage treatment, so those skilled in the art can give priority to designing protrusions as reinforcing ribs.

[0034] The utility model also has a bottom flange 12 on the top surface of the tank body 1, a top flange 22 on the top cover 2, a plug hole 13 on the bottom flange 12, and a plug protrusion 23 on the top flange 22 for plugging with the plug hole 13. When the tank body 1 and the top cover 2 are buckled, the assembly stability can be improved through the concave-convex plug structure. A reinforcing plate 14 is also provided between the bottom flange 12 and the tank body to further improve the reinforcement strength.

[0035] The utility model is provided with a side wall inserting groove 15 inside the tank body 1. Figure 3 As shown, several partitions are plugged in through the side wall plug-in grooves 15. This plug-in structure can improve the overall fit and fixing strength between the partition and the tank body 1, avoid the partition from tilting left and right after insertion, and ensure stability in the supporting state.

[0036] The partition divides the tank body 1 into a plurality of partitions. According to the sewage treatment process, the plurality of partitions include a cleaning area 3, an anaerobic treatment area 4, an aerobic treatment area 5, a sedimentation area 6, and a clean water area 7.

[0037] The partitions include a first partition 31, a second partition 34, a third partition 35, and a fourth partition 36; the partitions are provided with vertical and horizontal reinforcing ribs, and the overall strength of the partitions can be improved by the reinforcing ribs.

[0038] The arrangement structure of the first partition plate 31 and the third partition plate 35 is as follows: Figure 5 As shown, a bottom flow hole 37 is provided at the bottom of the partition, and vertical support parts 38 are provided on the left and right sides of the bottom flow hole 37. The vertical support parts 38 are pressed against the bottom surface of the tank body 1 or inserted into the side wall insertion groove 15 on the bottom surface of the tank body 1.

Figure 2 As shown, a vertical plug-in edge 33 is provided on the upper portion of the support surface 32 , and the vertical plug-in edge 33 is plugged into the plug-in groove on the inner side of the top cover 2 to achieve matching.

[0039] The purpose of arranging the vertical support portion 38 in the present invention is to ensure the strength and stability of the first partition plate 31 and the third partition plate 35 after being plugged and fixed.

[0040] like Figure 1 , 2 As shown, the utility model is provided with upper flow ports 39 on the second partition plate 34 and the fourth partition plate 36 ; the liquid in the anaerobic treatment zone 4 overflows into the aerobic treatment zone 5 through the upper flow ports 39 , and the clean water in the sedimentation zone 6 overflows into the clean water zone 7 .

[0042] The utility model fixes the suspended filler 40 through the anaerobic grid plate 41 and the aerobic grid plate 51. The purpose of setting such a suspended filler 40 is to promote the attachment of aerobic bacteria and enhance the aggregation and reproduction of aerobic bacteria. The utility model is provided with a bursting pipe 91 inside the aerobic treatment area 5. The bursting pipe 91 extends to the floating area of ​​the suspended filler 40. The bursting pipe 91 is designed as an air exhaust pipe, which is composed of a main pipe and a plurality of branch pipes 96. The main pipe and the branch pipe 96 are also provided with a plurality of air exhaust holes 97, and air is supplied to the inside of the aerobic treatment area 5 through the plurality of air exhaust holes 97.

[0043] The suspended filler 40 is arranged in a strip structure, such as Fig. 9 As shown, it includes a steel wire fixing part 42 at the center, the steel wire fixing part 42 is a stainless steel cable, and its outer periphery is coated with anti-corrosion glue. A mesh or flocculent parasitic blade 43 is wound and fixed on the steel wire fixing part 42. In this embodiment, a wire mesh winding structure is used to form a plurality of parasitic blades 43 after being wound into a circle. This design can increase the attachment space of aerobic bacteria. The utility model designs the parasitic blades 43 into multiple rows and spirally arranged around the steel wire fixing part 42. The purpose of this design is that when several branch pipes supply air, the airflow or water flow is disturbed to touch the parasitic blades 42 to the maximum extent, so as to promote the shedding of the aerobic bacterial biofilm on the parasitic blades 42, and at the same time promote the combination of aerobic bacteria and organic matter, thereby improving the decomposition efficiency.

[0044] The utility model is provided with a pipeline in the sedimentation area 6 connected to the cleaning area 3, and a drainage device is provided on the pipeline, through which the liquid is driven to flow from the sedimentation area to the cleaning area. The liquid referred to here is the muddy silt or sediment after sedimentation in the sedimentation area 6. In order to better realize the collection of such muddy silt in the sedimentation area 6, the utility model is provided with an inner inclined surface 61 at the bottom of the sedimentation area 6, and a mud bucket is formed by at least two inner inclined surfaces 61 to realize the centralized collection of muddy materials at the bottom.

[0045] Furthermore, in this embodiment, in order to avoid the use of external mechanical power for the drainage device, an air discharge pipe 8 is connected between the sedimentation area 6 and the cleaning area 3, the initial end 81 of the air discharge pipe 8 extends to the bottom of the sedimentation area 6, and the insertion end 95 of a high-pressure air pipe extends into the initial end 81 of the air discharge pipe 8. The sediment in the sedimentation area 6 can be transferred to the cleaning area 1 by air discharge through high-pressure gas, so as to facilitate centralized cleaning.

[0046] When the utility model supplies gas to the aerobic treatment area 5 and the initial end 81 of the gas exhaust pipe 8, the high-pressure gas pipe 9 is used in this embodiment to centrally supply gas. Figure 2As shown, the high-pressure air pipe 9 extends vertically and is provided with an explosion pipe 91 and an exhaust air supply pipe 93 at the bottom. The explosion pipe 91 extends into the aerobic treatment zone 5 and is provided with an explosion pipe switch 92. The exhaust air supply pipe 93 is provided with an exhaust switch 94 and extends into the sedimentation zone 6. The utility model uses the high-pressure air pipe 9 to independently supply air to and control the oxygen treatment zone 5 and the sedimentation zone 6.

[0047] When the utility model is working, Figure 6 As shown, domestic wastewater is guided to the cleaning zone 3 through an external pipe, and the wastewater is freely settled, with lighter wastewater floating on the top and heavier wastewater sinking to the bottom flow hole 37 at the bottom of the cleaning zone 3 and entering the anaerobic treatment zone 4. After anaerobic decomposition in the anaerobic treatment zone 4, an upward flow is formed, and the initially decomposed liquid overflows into the aerobic treatment zone 5 through the upper flow port 39. After being treated by aerobic bacteria, a downward flow is formed in the aerobic treatment zone 5, and the wastewater enters the sedimentation zone 6 from the bottom flow hole 37 at the bottom of the third partition plate 35. The wastewater is naturally precipitated in the sedimentation zone, and wastewater with high density is concentrated in the mud bucket, and wastewater with low density forms an upward flow, which overflows into the clean water zone 7 through the upper flow port 39 on the fourth partition plate 36. In this process, the wastewater concentrated in the mud bucket is guided to the cleaning zone 3 for centralized treatment under the action of the exhaust pipe 8. A technician in this field may set a drainage pump in the clean water zone 7 to discharge the clean water after decomposition and filtration.

[0048] In summary, the utility model realizes wastewater and sewage treatment through the cooperation of the cleaning zone 3, the anaerobic treatment zone 4, the aerobic treatment zone 5, the sedimentation zone 6, and the clean water zone 7 through the dual effects of aerobic and anaerobic, and effectively improves the sewage treatment efficiency; the bottom flow holes 37 on the multiple partitions cooperate with the upper flow ports 39 to form an upward flow and a downward flow of the wastewater inside the tank body 1, so that the wastewater can flow in a directional manner in the tank body 1, and the suspended filler 40 arranged in the anaerobic treatment zone 4 and the aerobic treatment zone 5 can realize aerobic and anaerobic treatment. During the treatment process, a single-point fixed suspended filler 40 is used to form a shaking bed, and an explosion pipe 91 is arranged in the suspended filler 40, which can regularly age and clean the microorganisms on the suspended filler 40 to improve the aerobic treatment efficiency. The above structure improves the sewage treatment efficiency and effect.

[0049] The utility model can improve the assembly strength and load-bearing strength by strengthening the outer wall and the partition structure of the tank body. Furthermore, the utility model also arranges a drainage device between the sedimentation area 6 and the cleaning area 3 to recover the mud and dirt to the cleaning area 3 for centralized recovery, so that the liquid processed in the subsequent process of the tank body 1 is cleaner.
