Description

Technical Field

[0001] This utility model belongs to the field of purification grid technology, and more specifically, it relates to an underground purification grid that has both air replenishment and deodorization functions. Background Technology

[0002] In traditional underground sewage treatment systems, the filtration screen, as the core component of sewage pretreatment, mainly serves to intercept suspended solids and large particulate impurities.

[0003] Based on the above, the inventors have discovered the following problems: the current purification grilles have poor deodorization efficiency during use and cannot intercept larger particulate impurities in sewage in a timely manner. As a result, the grilles may become clogged or damaged during subsequent treatment, indirectly reducing their efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an underground purification grille that combines air replenishment and deodorization functions, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of this utility model of an underground purification grille that combines air replenishment and deodorization functions are achieved by the following specific technical means: An underground purification grille with both air replenishment and deodorization functions includes a grille body, a number of guide plates at the top of the grille body, a frame at the bottom of the grille body, a number of through holes inside the frame, a filter mechanism inside the through holes, and a number of air replenishment holes on the surface of the grille body.

[0006] Furthermore, the grille body is made of stainless steel.

[0007] Furthermore, several sets of the guide vanes are installed at an angle to the top of the grille body.

[0008] Furthermore, the filtration mechanism includes an elastic filter screen, and an activated carbon adsorption layer is disposed below the elastic filter screen.

[0009] Furthermore, the elastic filter screen has a pore size of 2-5 mm and its surface is coated with a hydrophobic coating.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The design of the baffle plate guides the sewage into the screen at a more reasonable flow rate and direction, effectively avoiding local blockage caused by direct impact of sewage. At the same time, it makes the sewage more evenly distributed in the screen, providing good initial conditions for subsequent filtration, aeration and deodorization processes, and improving the pretreatment effect of the entire buried purification screen on sewage.

[0011] The combination of the flexible filter and the activated carbon adsorption layer can accurately intercept larger suspended solids and impurities in wastewater, preventing them from entering subsequent treatment stages and causing blockages and damage. At the same time, the hydrophobic coating on the surface of the flexible filter can effectively reduce the adhesion of impurities to the surface of the flexible filter, reduce the risk of blockage, extend the service life of the flexible filter, and ensure the initial purification effect of wastewater. Furthermore, under the action of the activated carbon adsorption layer, it can adsorb odorous gas molecules such as hydrogen sulfide and ammonia in wastewater, achieving deodorization from the perspective of physical adsorption. Combined with the air replenishment holes opened on the surface of the screen body, a micro-oxygen environment can be created, inhibiting the decomposition of organic matter intercepted by the screen under anaerobic conditions, reducing the generation of odors from the source. This dual effect significantly improves the environmental quality around the wastewater treatment site. Attached Figure Description

[0019] As attached Figure 1 To be continued Figure 3 As shown: This utility model provides an underground purification bar with both air replenishment and deodorization functions, including a bar body 1. The top of the bar body 1 is provided with several sets of guide plates 2, and the bottom of the bar body 1 is provided with a frame 3. The frame 3 has several sets of through holes 5 inside, and a filtration mechanism is provided inside the through holes 5. The surface of the bar body 1 is provided with several sets of air replenishment holes 4. Through the design of the guide plates 2, sewage can be guided into the bar at a more reasonable flow rate and direction, effectively avoiding local blockage caused by direct impact of sewage. At the same time, it makes the sewage more evenly distributed in the bar, providing good initial conditions for subsequent filtration, air replenishment and deodorization processes, and improving the pretreatment effect of the entire underground purification bar on sewage.

[0020] The grille body 1 is made of stainless steel.

[0021] Among them, several sets of the guide plates 2 are installed obliquely to the top of the grille body 1.

[0022] The filtration mechanism includes an elastic filter screen 6, with an activated carbon adsorption layer 7 positioned below it. The cooperation between the elastic filter screen 6 and the activated carbon adsorption layer 7 precisely intercepts larger suspended solids and impurities in the wastewater, preventing them from entering subsequent treatment stages and causing blockages and damage. Simultaneously, the hydrophobic coating on the surface of the elastic filter screen 6 effectively reduces the adhesion of impurities, lowers the risk of blockage, extends its service life, and ensures the initial purification effect of the wastewater. Furthermore, the activated carbon adsorption layer 7 adsorbs odorous gas molecules such as hydrogen sulfide and ammonia from the wastewater, achieving deodorization through physical adsorption. Combined with the air inlet holes 4 on the surface of the grille body 1, a micro-oxygen environment is created, inhibiting the decomposition of organic matter intercepted by the grille under anaerobic conditions, thus reducing odor generation at the source. This dual effect significantly improves the environmental quality surrounding the wastewater treatment site.

[0023] The elastic filter 6 has a pore size of 2-5 mm and its surface is coated with a hydrophobic coating.

[0024] The specific usage and function of this embodiment are as follows: During use, staff can assemble and install the bar screen body 1 for normal operation. The combination of the elastic filter screen 6 and the activated carbon adsorption layer 7 precisely intercepts larger suspended solids and impurities in the wastewater, preventing them from entering subsequent treatment stages and causing blockages and damage. Simultaneously, the hydrophobic coating on the surface of the elastic filter screen 6 effectively reduces the adhesion of impurities, lowers the risk of blockage, extends the service life of the elastic filter screen 6, and ensures the initial purification effect of the wastewater. Furthermore, the activated carbon adsorption layer 7 adsorbs odorous gas molecules such as hydrogen sulfide and ammonia in the wastewater, achieving deodorization through physical adsorption. Combined with the air inlet holes 4 on the surface of the bar screen body 1, a micro-oxygen environment is created, inhibiting the decomposition of organic matter intercepted by the bar screen under anaerobic conditions, reducing odor generation at the source. This dual effect significantly improves the environmental quality around the wastewater treatment site.
