[0002] Wastewater treatment is a process aimed at improving water quality to meet discharge or reuse standards. It is widely used in many fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and has gradually permeated people's daily lives.

[0003] In wastewater treatment processes, distribution wells are indispensable key equipment, responsible for the rational and even distribution of wastewater to the next stage of treatment structures. The stable operation of wastewater treatment plants or stations largely depends on the precise water distribution capacity of these wells. Uneven water distribution may lead to some structures operating under overload while others are underloaded, which not only fails to fully utilize the treatment efficiency of each structure but also affects the overall treatment effect. Currently, most wastewater engineering projects use hydraulic distribution methods to achieve uniform wastewater distribution. This method involves the water flowing to a certain height in the distribution well, and then using pipes or overflows to evenly introduce the wastewater into the next stage of treatment units. However, in actual operation, problems such as water pressure fluctuations, uneven foundation settlement, or unbalanced equipment installation can lead to uneven wastewater distribution, which in turn adversely affects subsequent treatment processes.

[0004] In view of this, it is necessary to provide an improved technical solution to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] refer to Figure 1 , Figure 2 , Figure 3 As shown, the water distribution well involved in this utility model includes a well body 100, an inlet pipe 200, a baffle plate 300, a water collection tank 40, and several distribution pipes 500. A more detailed description of the structure and their interconnections is provided below.

[0024] As shown in the figure, the well body 100 has a bottom wall 11 and a side wall 12 extending upward from the periphery of the bottom wall 11. The side wall 12 and the bottom wall 11 enclose a liquid storage cavity 10.

[0025] In this invention, the inlet pipe 200 is used to transport fluid to the storage chamber 10. In a specific application scenario of wastewater treatment, the fluid may be wastewater to be allocated to the next stage of treatment.

[0026] In this invention, the baffle plate 300 is fixed at the top of the liquid storage chamber 10, and a gap G is formed between its periphery and the side wall 12 of the well body 100 to allow fluid flow within the liquid storage chamber 10. It should be understood that fixing the baffle plate 300 at the top of the liquid storage chamber 10 means that the baffle plate 300 is at least partially embedded within the liquid storage chamber 10, thus forming the gap G for fluid flow within the liquid storage chamber 10. In a specific embodiment, refer to... Figure 3 As shown, the baffle 300 is fixed to the side wall 12 of the well body 100 by a number of fixed arms 31 distributed around it.

[0027] In this invention, the water collection tank 40 is arranged around the side wall 12 to collect the fluid overflowing from the top edge of the side wall 12 within the storage chamber 10. Specifically, the top edge of the side wall 12 forms an overflow weir. The fluid in the well body 100 needs to pass through the gap G before overflowing from the top edge of the side wall 12 into the water collection tank 40. Under the premise of continuous water supply from the inlet pipe 200, due to the action of the baffle plate 300, the water level rises faster in the gap G than at other locations in the storage chamber 10. This effectively prevents the water distribution well from experiencing flow interruption during the overflow of fluid from the well body 100 into the water collection tank 40, thereby ensuring the stability of the water distribution process.

[0028] In this invention, several water distribution pipes 500 are evenly distributed around the well body 100 and connected to the water collection tank 40. Since the water distribution well ultimately achieves water distribution through the water collection tank 40 and the water distribution pipes 500, the impact of fluid disturbance in the liquid storage chamber 10 on the uniformity of water distribution can be reduced. Furthermore, the even distribution of several water distribution pipes 500 can further improve the uniform distribution capability of the water distribution well.

[0029] Based on the specific structure of the water distribution well provided by this utility model, in specific sewage treatment application scenarios, it can ensure that sewage can flow stably and evenly to the next stage treatment unit, avoiding the problem of uneven sewage distribution in the existing water distribution well, thereby meeting the requirements of sewage treatment process and improving the overall treatment efficiency and effect of sewage treatment.

[0030] In a specific embodiment of this utility model, combined with Figure 1 , Figure 2 As shown, the water distribution well has a connecting wall 400 fixedly disposed around the side wall 12. The lower edge of the connecting wall 400 is connected to the side wall 12, and the connecting wall 400 and the portion of the side wall 12 near the top edge form a water collection trough 40. In this embodiment, the connecting wall 400 has an opening (not shown in the figure) for docking with the water distribution pipe 500. It can be understood that in other embodiments of this utility model, the water collection trough 40 may also be limited to the structure shown in the figure. For example, the water collection trough 40 may be formed by a trough wall independent of the well body 100, the inner edge of which is connected to the top edge of the side wall 12 (not shown in the figure).

[0031] As a preferred embodiment of this utility model, reference is made to... Figure 2As shown in the illustration, in this embodiment, the upper edge P1 of the connecting wall 400 protrudes beyond the plane P2 containing the top edge of the side wall 12. Based on this configuration, the direct outflow or splashing of fluid from the distribution well without passing through the distribution pipe 500 can be minimized, ensuring the reliability of the distribution well.

[0032] In the illustrated embodiment, the plane P2 containing the top edge of the sidewall 12 is located between the plane P3 containing the upper surface of the baffle 300 and the plane P4 containing the lower surface of the baffle 300. This design allows the fluid in the storage chamber 10 to overflow directly to the surrounding area after passing through the gap G around the baffle 300, ensuring that the overflow process at the top edge of the sidewall 12 is uninterrupted during the operation of the water distribution well, thereby ensuring the stability of the water distribution process of the water distribution well.

[0033] refer to Figure 1 As shown, in this specific embodiment, the inlet pipe 200 has a central pipe 21 fixed inside the storage chamber 10. The central pipe 21 is coaxially arranged with the well body 100, and an outlet 2110 is formed at the lower end of the central pipe 21. The outlet 2110 is spaced apart from the bottom wall 11. Since the central pipe 21 is coaxially arranged with the well body 100, the impact of the fluid flowing out of the outlet 2110 on the fluid in the storage chamber 10 can be evenly dispersed to the periphery. This can minimize the disturbance of the fluid entering the storage chamber 10 from the inlet pipe 200, thereby giving the water distribution well better stability.

[0034] In the specific implementation of this utility model, the coaxial arrangement of the central pipe 21 and the well body 100 means that the central axis of the central pipe 21 coincides with or approximately coincides with the central axis of the well body 100. As some preferred embodiments of this utility model, the cross-section of the well body 100 can be circular, square, or other relatively regular shapes, and its central axis refers to the axis passing through the center of the cross-section and perpendicular to the cross-section; for some well bodies 100 with irregular cross-sections, the central axis can be understood as the axis passing through the centroid of the cross-section and perpendicular to the cross-section.

[0035] Combination Figure 1 , Figure 3 As shown, in the specific implementation of this embodiment, a crossbeam 13 is fixed to the top of the well body 100, and the upper end of the central pipe 21 is fixedly connected to the crossbeam 13 through a fixing part 20, thereby fixing the central pipe 21. It can be understood that, based on the setting of the crossbeam 13, in some embodiments of this utility model, the baffle 300 can also be fixed by the crossbeam 13.

[0036] As shown in the figure, in this specific embodiment, the water inlet pipe 200 also has a connecting pipe 22 that connects to the top of the central pipe 21. The connecting pipe 22 extends from the outside of the liquid storage chamber 10 to the inside of the liquid storage chamber 10, so as to introduce external fluid (such as sewage) into the central pipe 21.

[0037] To further optimize the stability of the water distribution well operation, in some more specific embodiments, the end section 211 where the outlet 2110 of the central pipe 21 is located is configured in a funnel shape. (Reference) Figure 1 As shown, the central pipe 21 includes a main body section 212 and an end section 211 connected to the lower side of the main body section 212. The diameter of the main body section 212 remains unchanged in the length direction, while the diameter of the end section 211 gradually increases in the fluid outflow direction.

[0038] For the inlet pipe 200, under a constant flow rate, the larger the pipe diameter, the lower the flow velocity. The funnel-shaped design of the end section 211 reduces the velocity of the fluid (such as sewage) flowing out of the outlet 2110 from the central pipe 21, preventing excessive flow velocity from significantly agitating the solution in the storage chamber 10. This allows the fluid to rise slowly along the entire cross-section after entering the storage chamber 10. In the specific application of this utility model's water distribution well to sewage treatment, the flow velocity at the outlet 2110 of the central pipe 200 is no greater than 30 mm / s.

[0039] As a further preferred embodiment of this utility model, refer to Figure 1 As shown, the water distribution well also has a reflector plate 600 fixed in the liquid storage chamber 10. The reflector plate 600 is positioned opposite to the outlet 2110 of the water inlet pipe 200 and has a set distance from the bottom wall 11.

[0040] In the illustrated embodiment, the arrangement of the reflector 600 further reduces the disturbance of the solution in the storage chamber 10 caused by the water outlet 2110. In some specific embodiments, the gap height between the outlet 2110 of the central tube 200 and the surface of the reflector 600 is 0.3-0.5m. In this embodiment, there is a set distance between the reflector 600 and the bottom wall 11. In some specific embodiments, the distance between the reflector 600 and the bottom wall 11 is greater than 0.3m.

[0041] In the illustrated embodiment, preferably, the projection range of the outlet 2110 on the plane of the bottom wall 11 is within the projection range of the reflector 600 on the plane of the bottom wall 11. Based on this arrangement, the fluid flowing out of the outlet 2110 can be mitigated by the reflector 600 as much as possible.

[0042] In a more specific implementation, the projected area of ​​the outlet 2110 on the plane of the bottom wall 11 is S1, and the projected area of ​​the reflector 600 on the plane of the bottom wall 11 is S2, where S1 = 1.3 * S2.

[0043] Further preferred options, refer to Figure 1As shown, in some embodiments of this utility model, the upper surface of the reflector 600 is a cone with its apex pointing upwards, and the angle θ between the generatrix of the cone and the plane containing the bottom wall 11 ranges from 15° to 20°. In specific applications of wastewater treatment, this angle θ can buffer the impact of wastewater flowing out of the inlet pipe 200 on the reflector 600, so that the wastewater flowing out of the inlet pipe 200 forms a uniform flow under the action of the reflector 600, reducing the disturbance of suspended solids by water flow turbulence, and making the fluid in the storage chamber 10 rise uniformly and stably.

[0044] In a more specific embodiment, the angle θ between the generatrix constituting the conical surface and the plane containing the bottom wall 11 ranges from 17°.

[0045] In this utility model, as a further preferred embodiment, reference is made to... Figure 1 , Figure 2 As shown, each water distribution pipe 500 is also equipped with a regulating valve 50 for adjusting the flow rate. Based on the setting of the regulating valve 50, the flow rate of each water distribution pipe 500 can be controlled more precisely, thereby enabling the water distribution well of this utility model to have a better water distribution function.

[0046] To better understand this utility model, the specific operation mode of the water distribution well involved in this utility model is further described in detail below:

[0047] During the wastewater treatment process, external wastewater enters the inlet pipe 200. The water in the inlet pipe 200 flows out from the funnel-shaped outlet 2110 of the central pipe 21 into the storage chamber 10. After being impacted by the water pressure by the reflector plate 600, the water is evenly dispersed and slowly rises upward in the storage chamber 10. After passing the baffle plate 300 at the top of the storage chamber 10, the wastewater in the storage chamber 10 overflows evenly from the top edge of the side wall 12 to the collection tank 40. Then, it is discharged to the next stage treatment unit through several distribution pipes 500. During this process, the flow rate in the pipes on each distribution pipe 500 can be made consistent by the precise adjustment of the regulating valve 500, thereby achieving the purpose of uniform water distribution.

[0048] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0049] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
