Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically to a water collection structure and a biochemical reaction tank. Background Technology

[0002] Wastewater treatment systems often utilize microorganisms enriched within filter media (or packing materials) in the tank to remove impurities during the wastewater treatment process. However, existing biological reaction tanks require the installation of single or multiple effluent pipes on-site to transport the treated water, or the construction of an external effluent channel for overflow collection. This results in a large amount of on-site engineering work. Furthermore, the need for overflow space reduces the effective volume of the reaction zone, and uneven effluent discharge, along with short-circuit and dead zones within the tank, reduces treatment efficiency. Utility Model Content

[0003] In order to solve the technical problems existing in the background art, this utility model proposes a water collection structure for a biochemical reaction tank and a biochemical reaction tank.

[0004] This utility model proposes a water collection structure for a biochemical reaction tank, comprising: an outlet tank and a collection tank, wherein:

[0005] The end of the water outlet is provided with a drain outlet, and the side wall of the water outlet is provided with several water inlets spaced along its length.

[0006] The water collection trough is laid above the water outlet trough to be combined with the water outlet trough, and the water collection trough passes through the water outlet trough. The side wall of the water collection trough located outside the water outlet trough also has several water inlets spaced along its length direction. The bottom of the water collection trough located inside the water outlet trough has at least one water outlet.

[0007] Preferably, it also includes a pressure plate that covers the water collection tank and is connected to the water outlet tank as one piece.

[0008] Preferably, the pressure plate is a perforated plate or a mesh plate.

[0009] Preferably, the water outlet trough is provided with a slot that penetrates its side wall, and the water collection trough is fitted into the slot.

[0010] Preferably, multiple water collection troughs are provided and are laid on the water outlet trough at intervals along the length of the water outlet trough, and each water collection trough passes through the water outlet trough in sequence.

[0011] Preferably, there are multiple water outlet channels, which are arranged at intervals in their width direction; each water collection channel passes through each water outlet channel in turn.

[0012] Preferably, each water collection tank is connected to the other via a first connecting rod, and each water outlet tank is connected to the other via a second connecting rod, with the first connecting rod and the second connecting rod connected to form a whole.

[0013] Preferably, the water outlet is a U-shaped channel with an open top or a pipe channel that is closed circumferentially and open at the ends.

[0014] Preferably, it also includes a support frame, with the water outlet tank mounted on the support frame and the water collection tank connected to the support frame via a connecting rod.

[0015] The present invention proposes a biochemical reaction tank, wherein the interior of the reaction tank is filled with packing material, and a water collection structure as described above is provided above the packing material.

[0016] In this invention, the outlet tank and the collection tank are combined to form a single unit. During use, the tank is directly submerged in the reaction tank, eliminating the need for overflow / water-stirring space. This effectively reduces on-site construction workload and increases the effective volume of the reaction tank. Furthermore, this water collection structure can collect water from multiple directions and areas, ensuring uniform and smooth water flow and preventing uneven flow, dead zones in the packing reaction zone, and potential air-water short-circuiting during aeration, which could reduce reaction efficiency.

[0021] Reference Figure 1-2 The present invention proposes a water collection structure for a biochemical reaction tank, comprising: an outlet tank 1 and a collection tank 2, wherein:

[0022] The end of the water outlet 1 is provided with a drain outlet, and the side wall of the water outlet 1 is provided with several water inlets a spaced apart along its length.

[0023] The water collection trough 2 is laid above the water outlet trough 1 to be combined with the water outlet trough 1, and the water collection trough 2 passes through the water outlet trough 1. The side wall of the water collection trough 2 located outside the water outlet trough 1 is provided with several water inlets a spaced along its length direction. The bottom of the water collection trough 2 located inside the water outlet trough 1 is provided with at least one water outlet b.

[0024] In use, the water collection structure is directly immersed in the reaction tank. The clean water filtered by the packing material in the reaction tank enters the water collection tank 2 or the water outlet tank 1 through the inlet a on the water collection tank 2 or the water outlet tank 1 respectively. The water entering the water collection tank 2 flows into the water outlet tank 1 through the outlet b, and then flows out of the water outlet tank 1.

[0025] As can be seen from the above, this utility model directly combines the water collection tank 2 and the water outlet tank 1, allowing them to be directly submerged in the reaction tank during use. There is no need to set up an overflow / water spillway, thus effectively reducing on-site construction workload and increasing the effective volume of the reaction tank. Furthermore, this water collection structure can collect water from multiple directions and areas, ensuring uniform and smooth water flow and avoiding uneven water flow or dead zones in the packing reaction zone. In aeration mode, this could cause short-circuiting of air and water, leading to a decrease in reaction efficiency.

[0026] Furthermore, in this embodiment, the water outlet trough 1 is provided with a slot that penetrates its side wall, and the water collection trough 2 is fitted into the slot so that the water collection trough 2 and the water outlet trough 1 are combined together.

[0027] Furthermore, in this embodiment, there are multiple water collection tanks 2. Each water collection tank 2 is laid on the water outlet tank 1 at intervals along the length direction of the water outlet tank 1, and each water collection tank 2 passes through the water outlet tank 1 in sequence, so that the water inlet a of the water collection structure can be distributed in various areas of the pool to collect water, and the collected water is then discharged uniformly from the water outlet tank 1.

[0028] Furthermore, in this embodiment, multiple water outlet troughs 1 are provided and arranged at intervals in their width direction. Each water collection trough 2 passes through each water outlet trough 1 in sequence. This can further increase the distribution area of ​​the water inlet a, and also discharge the collected water from the water collection trough 2 and itself in a timely manner, ensuring smooth water intake for the water collection trough 2 and itself.

[0029] In addition, in this embodiment, each water collection tank 2 is connected to each other through a first connecting rod, and each water outlet tank 1 is connected to each other through a second connecting rod. The first connecting rod and the second connecting rod are connected to form a whole, thereby increasing the firmness of the connection between the water collection tank 2 and the water outlet tank 1; or, a support frame 4 is set up, and each water outlet tank 1 is installed on the support frame 4, and the water collection tank 2 is connected to the support frame 4 through a connecting rod 5.

[0030] In this embodiment, the water outlet trough 1 is a U-shaped trough with an open top, and can be made of channel steel, U-shaped steel, or other profiles. The water outlet trough 1 can also be a pipe trough that is circumferentially closed and open at the ends.

[0031] Similarly, water collection tank 2 also adopts a U-shaped groove with an open top or a pipe groove that is closed circumferentially and open at the ends.

[0032] Furthermore, the biochemical reaction tank water collection structure proposed in this utility model also includes a pressure plate 3 that covers the water collection tank 2 and is connected to the water outlet tank 1 as one piece. When applied to a reaction tank with lightweight filler, the pressure plate 3 can prevent the filler from leaking out.

[0033] Furthermore, the pressure plate 3 is a perforated plate or a mesh plate. The holes on the pressure plate 3 can ensure good venting effect and intercept the packing material to prevent the packing material in the pool from leaking out.

[0034] Reference Figure 3-4 The present invention proposes a biochemical reaction tank, wherein the interior of the reaction tank has packing material (not shown in the figure), and a water collection structure as described above is provided inside the reaction tank and above the packing material.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
