Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to an intensive regulating reservoir air permeation well with air supplementing and deodorization functions. BACKGROUND

[0002] The regulating reservoir is widely used in rainwater and sewage systems as an effective measure to control non-point source pollution and reduce peak flow of rainwater. Rainwater exceeding the processing capacity of the system can overflow into the regulating reservoir for temporary storage, and the stored rainwater can be discharged when the water volume is low, thereby playing a role of "peak load shifting". Meanwhile, the regulating reservoir can effectively control initial rainwater pollution and improve the ability of sewage treatment facilities to cope with impact load.

[0003] The rainwater and sewage stored in the regulating reservoir will emit odor during operation, and the odor must be treated by a deodorization process before being discharged. Since the frequency of use of the regulating reservoir is not fixed, the concentration of the odor generated is also not fixed, so the conventional biological deodorization process cannot be applied. When the regulating reservoir is discharged, air needs to be supplemented into the regulating reservoir to maintain the pressure balance between the inside and outside of the reservoir and ensure smooth discharge of the regulating reservoir. The common air supplementing method is to open the cover plate at the top of the regulating reservoir to allow air to circulate between the inside and outside of the reservoir, but this air supplementing method will cause the odor in the regulating reservoir to escape and pollute the surrounding environment.

[0004] With the increasing value of land resources, the top space of sewage treatment facilities is released for landscaping, which has become a new trend. How to combine the deodorization and air supplementing functions of the regulating reservoir, arrange intensively, save land, release the top space of the regulating reservoir, and meet the demand for landscaping has become an important part of the design of the regulating reservoir.

[0024] The application will be further described in detail below with reference to the accompanying drawings, so as to make the application clear.

[0025] The intensive regulating reservoir air well with the functions of air supplement and deodorization of the application is shown in Figures 1 to 4 .

[0026] The air well comprises an air well chamber 11, an air well wall 12, an air well steel concrete bottom plate 13, a molded grid bottom plate 14 and an air well top plate 15. The air well wall 12 is provided with a hole, and a residual pressure valve 21 and a rainproof louver 22 are installed on the hole. A horizontal air supplement pipeline 23 in the air well chamber 11 is connected with the residual pressure valve 21. The horizontal air supplement pipeline 23 is fixed on the air well top plate 15 by a pipeline support 25. A vertical air supplement pipeline 24 is connected with the horizontal air supplement pipeline 23 and extends into the regulating reservoir through the hole on the air well steel concrete bottom plate 13. An activated carbon cylinder 26 is placed on the molded grid bottom plate 14. A deodorization exhaust pipe 27 is installed on the air well wall 12. An external buckle rainproof cover plate 28 is installed on the air well top plate 15. A ladder 29 is installed on the air well wall 12.

[0027] When the regulating reservoir is filled with water, the odor in the regulating reservoir enters the activated carbon cylinder 26 placed on the molded grid bottom plate 14 through the hole on the air well steel concrete bottom plate 13. The activated carbon cylinder 26 is filled with small activated carbon particles, which have a large specific surface area and can effectively adsorb the odor in the regulating reservoir. The gas after deodorization by the activated carbon escapes from the top of the activated carbon cylinder 26, enters the air well chamber 11 and is collected by the deodorization exhaust pipe 27 to be discharged through an external exhaust pipeline.

[0028] When the regulating reservoir is drained, different pressure differences are formed inside and outside the air well corresponding to different water flow rates. A gravity hammer is installed on the residual pressure valve 21, which can adjust the opening degree of the residual pressure valve 21 according to different pressure differences, so as to control the air intake of the residual pressure valve 21. The air intake enters the horizontal air supplement pipeline 23 in the air well chamber 11 through the rainproof louver 22 and the residual pressure valve 21. The horizontal air supplement pipeline 23 and the vertical air supplement pipeline 24 form a T-shaped structure in the air well chamber 11. The horizontal air supplement pipeline 23 is connected with the residual pressure valve 21 and is used to collect the air intake and is fixed on the air well top plate 15 by the pipeline support 25. The vertical air supplement pipeline 24 is located in the center of the air well chamber 11, is connected with the horizontal air supplement pipeline 23 and the regulating reservoir through the hole on the air well steel concrete bottom plate 13 and is used to deliver the air intake to the regulating reservoir, so as to complete the automatic air supplement from the air well to the regulating reservoir.

[0029] The residual pressure valve 21 controlled by the gravity hammer is used as the air supplement device, and the opening degree of the residual pressure valve can be adjusted according to the pressure difference between the inside and outside of the regulating reservoir formed by different water flow rates, so as to adjust the air intake of the air vent well, realize automatic air supplement into the regulating reservoir, maintain the pressure balance between the inside and outside of the regulating reservoir, and ensure stable operation of the regulating reservoir

[0030] Since the service life of the activated carbon will be greatly shortened after being wet, in order to prolong the service time of the activated carbon and save operation cost, the special designed outer buckle type rainproof cover plate 28 is installed on the top plate 15 of the air vent well, and the rainproof louver 22 is installed on the well wall 12 of the air vent well. When it rains, the rainwater drops on the top plate 15 of the air vent well and the outer buckle type rainproof cover plate 28. Since the special designed clamping groove structure is formed between the top plate 15 of the air vent well and the outer buckle type rainproof cover plate 28, the rainwater cannot enter the well chamber 11 through the gap between the top plate 15 of the air vent well and the outer buckle type rainproof cover plate 28, so as to prevent the activated carbon particles from being wetted by water. The rainproof louver 22 installed on the well wall 12 of the air vent well can not only filter the air intake of the air vent well, but also effectively block the rainwater, so as to prevent the activated carbon particles from being wetted by the rainwater and prolong the service life of the activated carbon cylinder 26.

[0031] When the equipment in the air vent well needs to be replaced and maintained, the maintenance personnel can open the outer buckle type rainproof cover plate 28, enter the well chamber 11 through the self-climbing ladder 29, stand on the steel concrete bottom plate 13 of the air vent well to operate, and maintain and replace the activated carbon cylinder 26, the residual pressure valve 21, the horizontal air supplement pipeline 23 and the vertical air supplement pipeline 24 in the well chamber 11 of the air vent well. When a group of activated carbon cylinders 26 needs to be replaced as a whole, the outer buckle type rainproof cover plate 28 can be opened, the activated carbon cylinder fixed frame can be hoisted out as a whole by the crane, and the replacement can be directly performed.
