In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] The following is based on the attached Figure 1 To Attachment Figure 2 The utility model introduces a wastewater treatment station.

[0032] refer to Figure 1 , Figure 2As shown, in this embodiment, the wastewater treatment station mainly includes a pool 100, a mounting bracket 1, a plurality of sealing cover plates 2, a seal and an exhaust gas collection system. Among them, the core part of the wastewater treatment station is the pool 100, which is used to accommodate the wastewater to be treated. Compared with the closed pool 100, the open design can facilitate the construction of the entire wastewater treatment station, greatly reducing the construction and maintenance costs. At the pool mouth of the pool 100, a mounting bracket 1 is fixedly arranged. The mounting bracket 1 is made of high-strength metal material and has sufficient bearing capacity and stability. Multiple sealing cover plates 2 are arranged to abut and cover the pool mouth through the mounting bracket 1, which can conveniently and quickly form a closure of the pool 100, and also form a platform for inspection operators to walk, so that the inspection operators can easily inspect and repair various equipment on the sealing cover plate 2. The first air inlet end 31 of the exhaust gas collection system is set through the sealing cover plate 2 and is located in the pool 100, which can efficiently collect the exhaust gas generated in the pool 100. The outlet end of the waste gas collection system is connected to a waste gas treatment system, which uses waste gas treatment technologies such as combustion method to deeply treat the collected waste gas and ensure that the waste gas emissions meet environmental protection standards.

[0033] The pool 100 in the wastewater treatment process will directly emit a large amount of VOCs and odor into the air, causing serious pollution to the environment. By setting a sealing cover plate 2 to seal the pool 100, the exhaust gas is effectively prevented from being directly discharged into the atmosphere. The first air inlet 31 of the exhaust gas collection system passes through the sealing cover plate 2 and is placed in the pool 100, which can efficiently collect the generated exhaust gas. This design significantly reduces the pollution of the environment by exhaust gas and protects the air quality of the surrounding environment. At the same time, the sealing cover plate 2 not only seals the pool 100 and reduces the leakage of exhaust gas, but also forms a platform for inspection operators to walk on, which not only facilitates the walking of inspection operators, but also enables inspection operators to avoid direct contact with harmful exhaust gas, greatly reducing occupational health risks.

[0034] It should be noted that, by installing the bracket 1 and the sealing cover plate 2, the waste gas can be collected from the medium and large water pools 100 in a relatively economical manner. Specifically, the medium and large water pools 100 refer to the pool body structure with a length or width of the pool mouth not less than 4m. Of course, for some small water pools 100, the above-mentioned mounting bracket 1, sealing cover plate 2 and sealing member can also be used to collect the waste gas, which also falls within the scope of protection of the utility model.

[0035] Preferably, in order to ensure the sealing between the sealing cover plates 2 and prevent exhaust gas from leaking from the joints, a seal is provided at the joints between two adjacent sealing cover plates 2. The seal is made of corrosion-resistant and aging-resistant materials and can maintain a good sealing effect for a long time. Further preferably, in this embodiment, the sealing cover plate 2 is made of 304 stainless steel plate, which has excellent corrosion resistance and strength.

[0036] Further preferably, in this embodiment, butyl tape is used as a sealant to seal the joint between two adjacent sealing cover plates 2 by bonding. The butyl tape is made of butyl rubber, has excellent chemical corrosion resistance, weather resistance, wear resistance and service life, can maintain stable performance in a variety of harsh environments, and avoid seal failure due to wear. At the same time, the softness and ductility of butyl rubber enable the tape to fit tightly to the sealing cover plates 2 on both sides of the joint, and adapt to the change in the spacing of the joint caused by temperature changes.

[0037] Optionally, in order to enhance the stability between the sealing cover plates 2, the wastewater treatment station further comprises a cover plate connector. The cover plate connector can be bolted, snap-fitted, etc., and can fix two adjacent sealing cover plates 2 to form an integral structure, thereby greatly improving the bearing capacity and stability of the sealing cover plates 2.

[0038] Preferably, in this embodiment, the above-mentioned mounting bracket 1 adopts a square grid plate, and the sealing cover plate 2 adopts a rectangular or square plate. Compared with grid plates of other shapes that match sealing cover plates 2 of any shape, the square grid plate and the rectangular or square sealing cover plate 2 are more matched in shape, and the consistency of this shape helps to enhance the stability of the structure. The square grid can provide uniform support force, ensure that the sealing cover plate 2 can evenly distribute the weight when subjected to force, and reduce stress concentration or deformation caused by shape mismatch. At the same time, the square grid plate and the rectangular or square sealing cover plate 2 are easy to make, and the production cost is also low, which can also help reduce the construction or renovation cost of the wastewater treatment station. The length range of the sealing cover plate 2 is 0.8m-1.2m, and the width range of the sealing cover plate 2 is 0.5m-0.7m. The rectangular sealing cover plate 2 of 304 stainless steel of this size has a more economical production cost or purchase cost. For example, in this embodiment, the sealing cover plate 2 adopts a rectangular plate of 1m*0.6m.

[0039] It should be noted that most existing wastewater treatment stations include a stirring device 4 and an aeration device, which are indispensable parts of the wastewater treatment process. The stirring device 4 can fully stir the wastewater in the pool 100 to accelerate the dissolution and dispersion of pollutants in the wastewater. The aeration device injects air or oxygen into the wastewater to increase the dissolved oxygen content of the wastewater, promote the growth and metabolic activities of aerobic microorganisms, and thus accelerate the biological treatment process of the wastewater. During the stirring process and the aeration process, a large amount of VOCs and odor will directly enter the air, causing pollution to the environment.

[0040] Therefore, preferably, a through hole 21 is provided on at least one sealing cover plate 2, and a stirring device 4 or an aeration device is provided through the through hole 21 to perform stirring and aeration treatment on the wastewater. Figure 1 As shown, the stirring motor of the stirring device 4 is fixedly installed on the top surface of the sealing cover plate 2, and the stirring shaft is passed through the through hole 21, one end of which is connected to the stirring motor, and the other end is connected to the stirring paddle. At this time, the sealing cover plate 2 can limit VOCs and odors in the water pool 100 while achieving stirring until the exhaust gas is collected by the exhaust gas collection system.

[0041] Of course, in some other embodiments, a through hole 21 may be defined between at least two sealing cover plates 2, and the stirring device 4 and the aeration device are arranged in the through hole 21. This design not only facilitates the installation and maintenance of the equipment, but also ensures the uniformity and efficiency of wastewater treatment.

[0042] In order to further optimize the exhaust gas collection effect, the wastewater treatment station also includes an exhaust gas collection room. The exhaust gas collection room adopts a highly sealed design, which can effectively prevent the leakage and diffusion of exhaust gas. The water tank 100 is located in the exhaust gas collection room, ensuring the efficient collection of exhaust gas. Preferably, the exhaust gas collection room includes a plurality of fiberglass plates, which can be fixedly connected to form the side plates and the top plate of the exhaust gas collection room. The fiberglass plates are light in weight and low in cost, which can reduce the load of the mounting bracket 1 and the sealing cover plate 2, and can also further reduce the modification cost or construction cost of the wastewater treatment station.

[0043] Optionally, the exhaust gas collection system further has a second air inlet end 32, which is connected to the exhaust gas collection room and can conveniently collect the exhaust gas in the exhaust gas collection room, thereby further preventing the exhaust gas from being directly discharged into the environment.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
