Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment biological tank capable of emitting odorous gases. Background Technology

[0002] To address the contradiction between the environmental problems brought about by rapid economic development and people's pursuit of a better life and a higher quality of life, more and more sewage treatment plants are being built near urban residential areas. From the perspective of reducing the impact on the surrounding environment of the plant, the construction form of single-story covered sewage treatment plants and greening the top of the ponds has gradually become widely used. In addition, more and more local governments are demanding the construction of "garden-style" sewage treatment plants that are completely open to the public, which has put forward higher requirements for the collection and treatment of odors in the plant area.

[0003] The odor from wastewater treatment plants mainly originates from the pretreatment stage, the anaerobic tanks in the biological treatment stage, and the sludge thickening / dewatering / storage and transportation stage. Related treatment measures involve collecting and transferring the odor through deodorization hoods or pipes to a unified deodorization system for centralized treatment. However, in the aerobic zone, due to the cover, odor cannot dissipate through the ordinary open aeration tanks and accumulates inside the cover. Over time, the odor will escape from various inspection holes and lifting openings, causing damage to public experience and environmental benefits. Conventional underground wastewater treatment plants typically place odor collection and treatment devices below the cover; some also lay deodorization pipes on the top of the aeration tank to transport odor to deodorization equipment for treatment, both of which greatly increase project costs. Such practices are cumbersome and not cost-effective.

[0004] Therefore, it is necessary to provide a wastewater treatment biological tank that can discharge odors without affecting the environment in order to solve the problems existing in the prior art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a wastewater treatment biological tank that facilitates the discharge of odorous gases.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A wastewater treatment biological tank capable of emitting odorous gases includes a biological tank body and a platform installed on top of the biological tank body. The seat is hollow inside and communicates with the interior of the biological pool. An air inlet is provided on the side of the seat, and the interior of the seat is connected to the atmosphere through the air inlet. The main body of the biological tank is also connected to the atmosphere through a deodorizing duct. An axial flow fan is installed inside the deodorizing duct, which is used to exhaust the air inside the biological tank through the deodorizing duct.

[0007] As a further improvement to the above technical solution: The top of the biological pool body is provided with a through hole for connecting the deodorizing air duct. The other end of the deodorizing air duct bypasses the pool wall of the biological pool body and connects to the outside of the biological pool body. The opening of the end of the deodorizing air duct located outside the biological pool body faces the ground.

[0008] As a further improvement to the above technical solution: The seating platform is located away from the pool wall and is situated at the top of the aerobic zone of the main body of the biological pool.

[0016] Compared with the prior art, the advantages of this utility model are: A wastewater treatment biological tank capable of emitting odorous gases includes a main body of the biological tank and a platform mounted on top of the main body. The platform is hollow and communicates with the interior of the biological tank. An air inlet is located on the side of the platform, allowing the interior of the platform to communicate with the atmosphere. The interior of the biological tank is also connected to the atmosphere via a deodorizing duct. An axial flow fan is installed inside the deodorizing duct to exhaust air from inside the biological tank. This invention creates a negative pressure within the biological tank using the deodorizing duct and axial flow fan, allowing air to enter through the platform and exit through the deodorizing duct. This achieves rapid odor emission from the biological tank, resulting in a simple and economical structure. The deodorizing duct faces the ground, while the platform is located away from it and blocked by the tank wall, ensuring that odor emission does not affect the air environment for residents. The air inlet, located on the platform, serves both as an air intake and a resting area, blending seamlessly with the environment and not disrupting the landscape. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example: See Figures 1-3 A wastewater treatment biological tank capable of emitting odorous gases includes a biological tank body and a platform mounted on top of the biological tank body; the platform is hollow and communicates with the interior of the biological tank body, and an air inlet is provided on the side of the platform, through which the interior of the platform communicates with the atmosphere; the interior of the biological tank body is also connected to the atmosphere through a deodorizing duct, and an axial flow fan is installed in the deodorizing duct, which is used to exhaust air from the interior of the biological tank body through the deodorizing duct.

[0021] In this embodiment, the axial flow fan creates negative pressure in the biological tank after starting. Air is drawn in through the seating platform and then exhausted through the deodorizing duct, enabling rapid discharge of odors from the biological tank. The structure is simple and economical. The air inlet is set through the seating platform, which serves both as an air intake and a resting area. Moreover, it blends into the environment and does not damage the landscape.

[0022] The top of the biological pool body is provided with a through hole for connecting the deodorizing air duct. The other end of the deodorizing air duct bypasses the pool wall of the biological pool body and connects to the outside of the biological pool body. The opening of the end of the deodorizing air duct located outside the biological pool body faces the ground.

[0023] The deodorizing duct is installed facing the ground, and the seating area is far away from the deodorizing duct and blocked by the pool wall, so that the odor is discharged without affecting the nearby air environment.

[0024] The seating platform is located away from the pool wall and at the top of the aerobic zone of the main body of the biological pool. With this arrangement, the aerobic zone of the biological pool becomes a concentrated area of ​​odor. The seating platform, positioned within the aerobic zone, facilitates air convection, maximizing the removal of as much odor as possible from the biological pool.

[0025] The platform is also equipped with a viewing glass cover, through which the interior of the biological tank can be observed. The viewing glass cover allows observation of the mud-water mixing state within the tank, facilitating understanding of the tank's internal conditions, aeration uniformity, and other aspects; it also allows for targeted cleaning and maintenance. The side louvers ensure air circulation and significantly reduce the possibility of the viewing glass becoming fogged or blurred.

[0026] The air inlets are evenly distributed in multiple sets along the circumference of the seat on the side. In this embodiment, the seat is a cuboid, and the air inlets are set on the four sides according to the shape of the cuboid to maximize the ventilation effect. In different embodiments, different shapes of seats can be designed according to different needs and aesthetic requirements. The number of corresponding air inlets is set according to the direction of the aeration corridor in the biological tank, and the number and position are adjusted according to the aerobic zone structure of different scales.

[0027] The air inlet is also equipped with louvers. An insect screen is also installed on the side of the louvers facing outwards from the seating area. This combination of louvers and insect screen serves as the air inlet, ensuring airflow while preventing flying insects and other debris from escaping.

[0028] The louvers are installed inside the air inlet via slots. Installation via slots saves materials and is convenient.

[0029] The seating platform is 45cm-55cm higher than the top of the main body of the biological pool. The platform is designed according to ergonomic principles to be suitable for resting by operators or visitors.

[0030] The main body of the biological pond is also topped with a surface soil layer. This embodiment addresses the issue of odor in the aerobic zone of a single-layer covered biological pond by adapting to local conditions. Seating platforms are provided based on the characteristics of the greening on the pond roof, satisfying not only the needs of visitors for rest and recreation but also providing deodorization and other functional benefits.

[0031] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
