DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical schemes and beneficial effects to be solved by the present application more clear and apparent, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application. Embodiment one

[0039] As Figures 1 to 3 shown, the present application provides a sewage purification and odor treatment combined device, which comprises a sewage treatment tank 1, a deodorization assembly 2 is arranged on the tank opening of the sewage treatment tank 1, and the deodorization assembly 2 comprises a deodorization filler 21 to deodorize the sewage treatment tank 1. The deodorization assembly 2 not only effectively prevents the odor from being directly discharged from the sewage treatment tank 1 into the atmosphere, but also effectively adsorbs and decomposes the odor escaping from the sewage treatment tank 1 through the deodorization filler 21 inside the deodorization assembly 2, solves the problem of direct discharge of the odor of the biochemical tank, ensures the living quality of the surrounding residents, protects the atmospheric environment, and improves the regional environmental quality. At the same time, the sewage purification and odor treatment process of the present application can be carried out at the same time, without the need to construct independent treatment facilities respectively, thereby saving the land area, and saving the construction time and cost.

[0040] In this embodiment, wastewater treatment tank 1 is the main functional unit for wastewater treatment. It can employ activated sludge process, fluidized bed biofilm process (MBBR) process, or a combination of both. In actual design, the treatment process of wastewater treatment tank 1 can be designed according to actual needs. It should be noted that activated sludge process and fluidized bed biofilm process (MBBR) process are existing technologies, and this utility model is also an improvement on these aspects; therefore, their principles and processes will not be described in detail.

[0041] like Figure 1 , Figure 3 As shown, in this embodiment, the deodorization component 2 includes a frame 22 and a grating plate 23. The frame 22 is located at the inlet of the sewage treatment tank 1, and the grating plate 23 is laid at the bottom of the frame 22. A plastic mesh 24 is laid on the grating plate 23, and deodorizing filler 21 is laid on the plastic mesh 24. The frame 22 serves as the overall support structure for the deodorization component 2. The frame 22 is made of stainless steel, which has high strength and corrosion resistance, ensuring the overall stability and durability of the deodorization component 2. Furthermore, the grating plate 23 provides a uniform support surface for the deodorizing filler 21, ensuring the stability and uniform distribution of the deodorizing filler 21. The grating plate 23 can be designed to be made of stainless steel or fiberglass, both of which have good corrosion resistance and wear resistance, and can withstand the weight of the deodorizing filler 21 for a long time. In addition, the mesh size of the plastic mesh 24 is 50% to 70% of the particle size of the deodorizing filler 21, that is, the mesh size of the plastic mesh 24 is smaller than the particle size of the deodorizing filler 21, which can prevent the deodorizing filler 21 from falling into the sewage treatment tank 1 through the mesh of the plastic mesh 24.

[0042] In this embodiment, the deodorizing filler 21 can be selected as a single or composite component filler, and the filling in each area is uniform and of consistent thickness. At the same time, the area and thickness of the deodorizing filler 21 layer should be calculated according to the odor concentration, composition, and volume, and meet the requirements of the "Technical Specification for Odor Treatment of Urban Wastewater Treatment Plants" CJJ / T 243-2016, with sufficient margin reserved.

[0043] In this embodiment, the bottom surface of the deodorizing component 2 is a plane, and the height of the deodorizing component 2 is 1m to 1.5m. The height of the deodorizing component 2 can be designed to be any value in the range of 1m, 1.1m, 1.2m, 1.3m, 1.4m, 1.5m, etc. In actual design, the height of the deodorizing component 2 can be designed according to actual needs.

[0044] like Figures 1 to 5As shown, in this embodiment, the top of the deodorizing filler 21 is provided with a movable cover plate 25, which facilitates maintenance, greatly simplifies the maintenance process, and improves work efficiency. When maintenance is not required, the movable cover plate 25 can tightly cover the deodorizing filler 21, preventing external debris from entering and protecting the deodorizing component 2 from damage. Furthermore, the movable cover plate 25 is provided with a receiving groove, the bottom of which has multiple holes with an opening rate of not less than 40%, serving to allow air and water permeability. This allows water to flow through, preventing water accumulation and allowing rainwater or sewage to drain quickly, keeping the deodorizing component 2 dry and clean. In addition, a layer of hard granular filler, 5cm thick, is laid inside the receiving groove. The material of the hard granular filler layer is pebbles, volcanic rock, etc., which not only provides a light-blocking effect but also enhances the aesthetics of the deodorizing component 2.

[0045] like Figures 1 to 5 As shown, in this embodiment, a spray pipe 26 is provided between the movable cover plate 25 and the deodorizing packing material 21 to keep the deodorizing packing material 21 in a humid environment, maintain the activity of microorganisms on the surface of the deodorizing packing material 21, and improve the deodorization effect. Furthermore, to ensure that the spray water covers the entire area of ​​the deodorizing packing material 21, the distance between the nozzle of the spray pipe 26 and the top of the deodorizing packing material 21 layer is not less than 20cm. The spray water can be treated wastewater from a sewage treatment plant, which conforms to the concept of environmental protection and can also realize the recycling of water resources; if the wastewater in the plant area is disinfected with agents such as sodium hypochlorite, the spray water should be taken from before the disinfection process section to prevent residual disinfectant from affecting the growth of deodorizing microorganisms.

[0046] like Figure 5 As shown, in this embodiment, there is a gap between the deodorization component 2 and the water surface of the sewage treatment tank 1. The width of the gap is 0.2m to 0.3m, so that when the odor enters the deodorization component 2 through the gap, it can fully contact and react with the deodorization packing 21, thereby further improving the deodorization effect.

[0047] like Figures 1 to 5 As shown, in this embodiment, a plant area 3 is provided within the deodorizing component 2. Specifically, a plant planting trough 27 is provided within the deodorizing component 2, and the plant area 3 is located within the plant planting trough 27. The plant planting trough 27 and the deodorizing component 2 are separated by a steel plate, and a sealing strip is used to seal the plant planting trough 27 and the steel plate to prevent odor from leaking out through gaps. In addition, since the plant area 3 is adjacent to the deodorizing component 2, a very small amount of odor that the deodorizing component 2 does not completely absorb will be absorbed by the plants 33 in the plant area 3, resulting in a higher overall deodorization guarantee. Furthermore, if equipment such as submersible mixers, submersible return pumps, and instrument probes in the sewage treatment tank 1 require maintenance ports or lifting ports, the lifting ports should be separated from the deodorizing filler 21 area by steel plates, and sealed covers should be installed at the openings to prevent untreated odor from being directly emitted from these points.

[0048] As Figure 6 , Figure 7 shown in the present embodiment, the plant planting groove 27 can adopt a modular straight cylinder structure with a square or regular hexagonal cross section, embedded inside the deodorizing assembly 2, and can be independently disassembled and replaced. In addition, a plurality of plant planting grooves 27 are combined together, which can be assembled into various patterns to meet the needs of simple landscaping, or a single large size special-shaped planting groove can be used to meet the needs of complex landscaping. In actual design, the position, shape and size of the deodorizing assembly 2 and the plant area 3 can be flexibly matched according to the shape of the sewage treatment tank 1.

[0049] As Figures 1 to 5 shown in the present embodiment, the plant area 3 includes a gravel layer 31, a planting soil layer 32, and a planted plant 33. The gravel layer 31 and the planting soil layer 32 are sequentially laid from bottom to top along the groove bottom of the plant planting groove 27, and the planted plant 33 is planted in the planting soil layer 32. In addition, the soil quality and thickness of the planting soil layer 32 should ensure that its ventilation resistance is much greater than that of the deodorizing filler 21 layer under the premise of normal growth of the planted plant 33, to prevent odor from leaking through the planting groove. In addition, the planted plant 33 is mainly composed of perennial emergent marsh plants with strong growth and strong pollution resistance, which can absorb organic pollutants and odor such as hydrogen sulfide and ammonia in water, such as reed, alocasia, canna, etc. The shallow layer is matched with plants for driving insects and deodorizing, such as mint, rosemary, artemisia, etc. At the same time, due to the limitation of the carrying capacity of the device, it is not suitable to plant tall trees.

[0050] As Figures 1 to 5 shown in the present embodiment, the groove bottom of the plant planting groove 27 is a hollow structure, and the sewage treatment tank 1 includes an aerobic zone 11 and an anaerobic zone 12. The aerobic zone 11 and the anaerobic zone 12 are both provided with a deodorizing assembly 2. The hollow structure of the plant planting groove 27 of the aerobic zone 11 is immersed below the water surface of the sewage treatment tank 1. The root system of the planted plant 33 penetrates through the planting soil layer 32 and extends into the gravel layer 31, directly contacts with the sewage in the aerobic zone 11, absorbs organic matter and nutrients in water for its own growth, and provides oxygen for rhizosphere microorganisms, so as to achieve the effect of promoting sewage purification and enhance the sewage purification effect of the sewage treatment tank 1. At the same time, the plant area 3 can also beautify the environment and improve the ecological quality and landscape effect of the surrounding area.

[0051] As Figures 1 to 5As shown, in this embodiment, to prevent the roots of the plant 33 from supplying oxygen and disrupting the anaerobic environment inside the anaerobic zone 12, the hollow structure of the plant planting trough 27 in the anaerobic zone 12 is located above the water surface of the sewage treatment tank 1. The roots of the plant 33 do not directly contact the sewage in the anaerobic zone 12. This part of the plant 33 mainly serves a deodorizing function, absorbing the very small amount of odor that the deodorizing component 2 does not completely absorb, thus improving the deodorizing effect. In addition, a water storage tray 34 is provided at the bottom of the plant area 3 in the anaerobic zone 12, which can store a small amount of spray water or rainwater from the deodorizing filler 21, providing the necessary water for the growth of the plant 33.

[0052] like Figures 2 to 5 As shown, in this embodiment, the height of the portion of the plant planting trough 27 in the aerobic zone 11 located within the wastewater treatment tank 1 is 0.2m to 0.3m, facilitating contact between the plants 33 within the planting trough 27 and the wastewater in the aerobic zone 11. The roots of the plants 33, through mechanisms such as absorption, adsorption, and biodegradation, can more effectively remove nutrients (such as nitrogen and phosphorus) and organic pollutants from the wastewater, thereby improving the wastewater purification efficiency. Furthermore, the bottom of the plant planting trough 27 in the anaerobic zone 12 is flush with the bottom of the deodorization component 2, making the layout of the entire wastewater treatment system more compact and rational.

[0053] In this embodiment, the bottom of the deodorizing component 2, the bottom of the plant area 3, and the space above the water surface of the sewage treatment tank 1 should be kept in communication so that the odor is evenly distributed below the deodorizing component 2, ensuring that the ventilation load of the deodorizing component 2 remains consistent and avoiding short-circuiting. When the reinforced concrete structure 5 at the top of the sewage treatment tank 1 is lower than the highest water level of the sewage treatment tank 1, ventilation holes should be provided in the upper middle part of the reinforced concrete structure 5 above the water surface.

[0054] like Figures 6 to 7 As shown, in this embodiment, the deodorization component 2 can completely cover the top space of the sewage treatment tank 1. The deodorization component 2 can also be combined with the reinforced concrete structure 5 to cover the top space of the sewage treatment tank 1. In actual design, the coverage area of ​​the deodorization component 2 can be designed according to the strength requirements of deodorization and water treatment functions.

[0055] In this embodiment, when the present invention is used only for deodorizing sewage treatment tank 1 with a wide coverage area and low ventilation resistance of the deodorization component 2, there is no need to install deodorization hoods, fans, collection pipes and other facilities. The odor generated in sewage treatment tank 1, such as the odor carried out by the aeration in the aerobic zone 11 of sewage treatment tank 1 and the odor generated by fermentation in the anaerobic zone 12 of sewage treatment tank 1, diffuses upward under the action of aeration residual pressure and is adsorbed and degraded when passing through the deodorization component 2. Compared with traditional biological deodorization devices, the layout of the present invention is more flexible, more concealed, has lower energy consumption and better landscape effect. Example 2

[0056] As Figure 8 shown, when the deodorization assembly 2 of the present embodiment needs to consider other facilities deodorization, the sewage purification and odor treatment combined device further comprises an odor pipe 4, the gas outlet of the odor pipe 4 communicates with the aerobic zone 11 of the sewage treatment tank 1, the gas outlet of the odor pipe 4 is located below the water surface of the aerobic zone 11 of the sewage treatment tank 1, and a filter screen 41 is arranged at the gas outlet of the odor pipe 4. The deodorization fan collects the odor in other facilities and transmits it through the odor pipe 4, the odor entering the filter screen 41 from the odor pipe 4 is cut into small bubbles, the bubbles are washed by the sewage in the sewage treatment tank 1, the dust and part of the soluble odor components are transferred to the sewage, removed by microbial metabolism in water, and the remaining humid gas is removed by the deodorization filler 21 in the deodorization assembly 2 after the water.

[0057] In the present embodiment, the distance between the gas outlet of the odor pipe 4 and the water surface of the aerobic zone 11 of the sewage treatment tank 1 is 10cm~20cm, which not only ensures that the odor can be effectively washed in the sewage treatment tank 1, but also controls the outlet water pressure, reduces the outlet pressure of the deodorization fan to reduce energy consumption. In addition, the highest point of the part of the pipeline of the odor pipe 4 located outside the sewage treatment tank 1 is at least 0.5m higher than the highest water level of the sewage treatment tank 1, that is, before the odor pipe 4 enters the sewage treatment tank 1, the highest point of the odor pipe 4 should be at least 0.5m higher than the highest water level of the sewage treatment tank 1, so as to prevent the sewage from flowing back to the main pipe of the deodorization fan and ensure the stable operation of the system.

[0058] It should be understood that those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present utility model.

[0059] The above has exemplarily described the present utility model patent in combination with the drawings, and obviously the implementation of the present utility model patent is not limited by the above manner, as long as various improvements are made by adopting the method concept and technical scheme of the present utility model patent, or the concept and technical scheme of the present utility model patent is directly applied to other occasions without improvement, all of which are within the protection scope of the present utility model.
