[0002] In the field of environmental protection and water resource treatment, the main purpose of sewage filtration treatment is to remove suspended matter, particulate matter, organic matter and other impurities in sewage to improve water quality. In related technologies, sewage filtration equipment mostly relies on the principle of natural stillness to work. However, the filtration speed of natural stillness is relatively slow, which affects the efficiency of the entire sewage treatment process. Especially when treating a large amount of sewage, this inefficient filtration method may lead to a longer treatment cycle, increasing operating costs and time costs. Summary of the invention

[0003] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In the related art, sewage filtration equipment generally introduces the sewage to be treated into the filtration device. Subsequently, relying on the action of gravity, the heavier substances such as suspended matter and impurities in the sewage will gradually settle and accumulate in the bottom area of ​​the device. The relatively light and clear water will flow through the pre-laid filter medium layer under the action of gravity until finally obtaining a water body with purer composition. However, this sewage filtration method meets the basic sewage treatment needs to a certain extent, but it still has problems such as low filtration efficiency, long treatment cycle, and high maintenance cost.

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a sewage treatment device, which includes a filter chamber 10, a suction pump 20, a water collection tank 30 and a plurality of water inlet pipes 17. A filter screen 50 is provided in the filter chamber 10, and the filter screen 50 divides the filter chamber 10 into a water inlet chamber 11 and a water outlet chamber 12. The filter chamber 10 is provided with a plurality of water inlets 13 connected to the water inlet chamber 11, and the plurality of water inlets 13 are arranged in a spiral shape around the water inlet chamber 11; the water inlet pipe 17 is connected to the water inlet 13 in a one-to-one correspondence; the suction pump 20 has a water suction port 21 and a water discharge port 22, the water suction port 21 is connected to the water outlet chamber 12, and the water discharge port 22 is connected to the water collection tank 30.

[0029] Specifically, the filter screen 50 separates the filter chamber 10 into two independent spaces, an inlet chamber 11 and an outlet chamber 12. The inlet chamber 11 is responsible for receiving the sewage to be treated, while the outlet chamber 12 outputs the clean water after filtration. A plurality of water inlets 13 are provided on the filter chamber 10, and the water inlets 13 are arranged in a spiral manner around the inlet chamber 11, which not only increases the water inlet area, but also promotes the uniform distribution of water flow in the inlet chamber 11, avoiding the problem of uneven filtration caused by local water flow being too fast or too slow. At the same time, the increase in the number of water inlets 13 significantly increases the water inlet flow rate, thereby increasing the pressure in the inlet chamber 11, providing sufficient power for the subsequent filtration process.

[0030] In addition, the water suction port 21 of the suction pump 20 is directly connected to the water outlet chamber 12, and the water outlet 22 of the suction pump 20 is connected to the water collection tank 30 through the water outlet pipe 18. When the suction pump 20 is started, its strong suction force will quickly extract the filtered water in the water outlet chamber 12, and send it to the water collection tank 30 for storage through the water outlet 22. In this process, the water in the water outlet chamber 12 is quickly extracted, resulting in a negative pressure area inside the water outlet chamber 12, while the water inlet chamber 11 maintains a relatively high positive pressure state due to the continuous water inflow. In this way, a significant pressure difference is formed between the water inlet chamber 11 and the water outlet chamber 12. This pressure difference becomes a powerful driving force to push the sewage through the filter screen 50 into the water outlet chamber 12, thereby greatly promoting the rapid separation and filtration of impurities in the sewage, and effectively improving the efficiency of the entire sewage treatment process.

[0031] In summary, the sewage treatment equipment provided in the embodiment of the present invention not only significantly improves the efficiency of sewage treatment, shortens the treatment cycle, reduces operating costs, but also ensures the cleanliness and safety of the effluent water quality through the synergistic effect of multiple water inlets 13 and the suction pump 20.

[0032] In some embodiments, the filter 50 has multiple bending sections 51, the bending section 51 has a recessed area 52 recessed from the water inlet chamber 11 to the water outlet chamber 12, at least part of the opening of the water inlet 13 is arranged toward the recessed area 52, and at least part of the opening of the water inlet 13 is arranged toward the recessed area 52.

[0033] Specifically, the recessed area 52 can make the filter 50 have a more complex spatial structure, enriching the flow path of water on the surface of the filter 50. In addition, the opening of part of the water inlet 13 faces the recessed area 52, so that the sewage pouring in from the water inlet 13 can more directly impact the recessed area 52 of the filter 50, thereby forming a stronger turbulence effect in the recessed area 52. This effect not only accelerates the contact and collision between the sewage and the surface of the filter 50, but also promotes the effective separation of pollutants such as impurities and suspended matter in the sewage from the filter 50, further improving the filtration efficiency.

[0034] Furthermore, the arrangement of the water inlet 13 toward the recessed area 52 also helps to optimize the distribution of water flow on the surface of the filter 50. In the traditional design of the filter 50, water flow is often easy to form certain "dead corners" on the surface of the filter 50, resulting in a significant reduction in the filtering effect of these areas. However, this design in the present invention can guide the water flow to cover the entire surface of the filter 50 more evenly, avoiding the generation of "dead corners" and ensuring that each filter 50 can fully exert its filtering effect.

[0035] Furthermore, the bending section 51 includes a first cylinder 511, a second cylinder 512, a first ring plate 513 and a second ring plate 514. The first cylinder 511 and the second cylinder 512 are coaxially arranged, and the first cylinder 511 and the second cylinder 512 are staggered in the axial direction of the filter 50 to form a recessed area 52. The first ring plate 513 is connected between the first cylinder 511 and the second cylinder 512, and the second ring plate 514 is arranged parallel to the first ring plate 513, and the second ring plate 514 is connected to one of the first cylinder 511 and the second cylinder 512.

[0036] Among them, there is a certain distance difference between the first cylinder 511 and the second cylinder 512 in the axial direction of the filter 50, and this staggered arrangement cleverly forms a concave area 52 on the surface of the filter 50. The first ring plate 513 is connected between the first cylinder 511 and the second cylinder 512, ensuring the overall stability of the bending section 51 and also providing a guarantee for the smooth flow of water on the surface of the filter 50. The existence of the first ring plate 513 allows the water flow to transition more smoothly when flowing through the bending section 51, avoiding the turbulence effect caused by structural mutations, thereby reducing the impact and wear of the water flow on the filter 50.

[0037] The second annular plate is connected to one of the first cylinder 511 and the second cylinder 512 to achieve the connection between two adjacent bending sections 51. That is, when water flows into the filter screen 50 from the water inlet 13, it flows along the concave area 52 of the bending section 51 and smoothly transitions to the next bending section 51 under the guidance of the second annular plate. In this process, the contact area between the water flow and the surface of the filter screen 50 is maximized, thereby improving the filtering efficiency.

[0038] Furthermore, the bending section 51 is set to be in a bow shape. Each bending section 51 presents a bow-like curved shape, forming a bow-like curved path. When the water flows into the filter 50 from the water inlet 13, it flows along the bow-shaped curved path. During this process, the speed and direction of the water flow will undergo subtle changes, which helps to enhance the collision and friction between the water flow and the surface of the filter 50, thereby more effectively trapping impurities, suspended matter and other pollutants in the sewage on the surface of the filter 50.

[0039] In some embodiments, the filter 50 is configured to be annular, the water outlet chamber 12 is configured inside the filter 50, and the water inlet chamber 11 is configured outside the filter 50, so that impurities remain on the outer surface of the filter 50, making it convenient to clean the filter 50.

[0040] In some embodiments, the filter 50 is made of a single layer or multiple layers of activated carbon material, so that the filter 50 can fully utilize the adsorption capacity of activated carbon during the process of filtering sewage, effectively remove pollutants such as organic matter, residual chlorine, odor, pigments, etc. in the water, thereby providing cleaner and safer water output.

[0041] In some embodiments, the filter chamber 10 includes a cover plate 14 and a bottom plate 15 that are arranged opposite to each other, a mounting plate 53 is arranged on the top of the filter screen 50, and an elastic member 54 is arranged on the bottom of the filter screen 50, the mounting plate 53 is detachably connected to the cover plate 14, and the two ends of the elastic member 54 abut against the bottom plate 15 and the filter screen 50, so as to facilitate the removal of the filter screen 50. In addition, one end of the elastic member 54 abuts against the bottom plate 15, and the other end is connected to the body of the filter screen 50, which can provide a certain buffer and shock absorption effect for the filter screen 50 during the filtering process, and the installation height and inclination angle of the filter screen 50 can also be adjusted according to actual needs, so as to optimize the distribution and flow path of water flow on the surface of the filter screen 50.

[0042] Optionally, the mounting plate 53 and the top plate may be configured to be bolted or snap-fitted to facilitate assembly and disassembly of the filter screen 50 .

[0043] In some embodiments, the sewage treatment equipment further includes a booster pump 60, which is disposed on the water inlet pipe 17. When sewage enters the sewage treatment equipment through the water inlet pipe 17, the booster pump 60 will start and work immediately to increase the water flow pressure to a preset range. This increased water flow pressure not only helps to overcome the resistance of the filter screen 50 and the pipeline system, but also ensures that the sewage forms a stable and uniform water flow layer on the surface of the filter screen 50, thereby improving the filtration efficiency and interception rate.

[0044] like Figure 3 As shown, in some embodiments, a float 23 is provided on the suction pump 20, and the suction pump 20 and the float 23 are arranged in the water outlet chamber 12, so that the suction pump 20 can automatically rise and fall with the change of the water level in the water outlet chamber 12, which can effectively avoid the dry operation problem caused by too low water level.

[0045] like Figure 3 As shown, in some embodiments, an observation port 16 is provided on the filter chamber 10, and a transparent plate is provided at the observation port 16, which allows the operator to intuitively observe the working status in the filter chamber 10 and the filtering effect of the filter screen 50 without opening the filter chamber 10, and also greatly improves the operation monitoring and fault diagnosis capabilities of the equipment.

[0046] like Figure 4 As shown, in addition, in one embodiment of the present invention, a sewage treatment system is also provided, which includes the sewage treatment equipment provided in the above embodiment, and the sewage treatment equipment is provided with multiple sewage treatment equipment, and the multiple sewage treatment equipment is arranged in series or in parallel. Figure 4 It can be seen that the multiple sewage treatment equipments are arranged in series, that is, the water inlet pipe 17 of one of two adjacent sewage treatment equipments is connected to the water collection tank 30 of the other one.
