Description

Technical Field

[0001] This utility model relates to the field of wastewater and waste gas treatment technology, specifically a treatment device for the synergistic treatment of odors using advanced oxidation and biological filters. Background Technology

[0002] Advanced oxidation processes (AOPs) and biofilters are two commonly used technologies for removing pollutants from air or water. AOPs break down recalcitrant organic matter by generating strong oxidants (such as hydroxyl radicals (·OH)). These radicals are highly reactive and can oxidize most organic pollutants into carbon dioxide and water. Common AOP combinations include hydrogen peroxide / UV light and ozone / UV light. Biofilters, on the other hand, utilize microbial communities to degrade pollutants. Wastewater passes through a microbial-rich medium in the biofilter, where these microorganisms metabolize harmful substances, thus purifying the wastewater. When these two technologies work synergistically, they can effectively treat odorous exhaust gases or wastewater.

[0003] Existing odor treatment devices that combine advanced oxidation and biological filters integrate advanced oxidation technology with biological filters. For example, CN115367960A discloses a wastewater deep treatment device that couples catalytic oxidation and biological filters. This device can achieve deep treatment of wastewater, improve the utilization efficiency of ozone / hydrogen peroxide, and promote stable compliance of wastewater treatment results. However, during the wastewater treatment process, waste gases such as carbon dioxide are generated, and these waste gases contain some pollutants. If the waste gases are discharged directly, the pollutants will leak. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2This utility model provides a technical solution: a treatment device for synergistic treatment of odors using advanced oxidation and biological filtration, comprising a treatment device body 1. The treatment device body 1 contains, in sequence, a pretreatment tank 2, a first advanced oxidation tank 4, a second advanced oxidation tank 6, a first biological filter 8, and a second biological filter 9. A cover plate 3 is fixedly installed on the upper ends of the pretreatment tank 2, the first advanced oxidation tank 4, and the second advanced oxidation tank 6. An exhaust pipe 5, connected to the first and second advanced oxidation tanks respectively, is installed on the cover plate 3. The other end of the exhaust pipe 5 is connected to a second air distribution pipe 15 via an air pump. This structure, by sealing the tops of the first and second advanced oxidation tanks 4 and 6 with the cover plate 3, allows for the unified collection of gases generated during wastewater treatment. The gas is introduced into the second gas distribution pipe 15 and then evenly distributed into the first biological filter 8 for further treatment. Catalyst layers 13 are installed in the first advanced oxidation tank 4 and the second advanced oxidation tank 6, and first gas distribution pipes 14 are installed at the bottom of the catalyst layers 13. Support plates 12, support layers 11, and filter media layers 10 are arranged sequentially from bottom to top in the first biological filter 8 and the second biological filter 9. Water distribution pipes 7 and second gas distribution pipes 15 are respectively installed above and below the first biological filter 8. A rectangular inlet baffle 203 is integrally installed in the pretreatment tank 2, and a sewage inlet pipe 201 is inserted and fixed into the inner area of ​​the inlet baffle 203 on the side of the pretreatment tank 2. The inlet section is equipped with a through hole communicating with the pretreatment tank 2, and a filter screen cylinder 202 is snapped and fixed inside the inlet baffle 203. The wastewater inlet pipe 201 is connected to the inside of the filter screen cylinder 202. This structure allows wastewater to enter the filter screen cylinder 202 through the wastewater inlet pipe 201 for filtration. After preliminary filtration by the filter screen cylinder 202, the wastewater flows into the pretreatment tank 2 through the through hole on the side of the inlet baffle 203 for temporary storage. The wastewater in the pretreatment tank 2 directly enters the first advanced oxidation tank 4. The bottoms of both sides of the first advanced oxidation tank 4 are connected to the pretreatment tank 2 and the second advanced oxidation tank 6, respectively. The bottoms of the first biological filter tank 8 and the second biological filter tank 9 are connected. This structure allows the treated wastewater in the first advanced oxidation tank 4 to further enter the pretreatment tank 2. The wastewater enters the second advanced oxidation tank 6, while the wastewater treated in the first biological filter 8 then enters the second biological filter 9 to improve the wastewater treatment effect. The first advanced oxidation tank 4, the second advanced oxidation tank 6, and the second biological filter 9 are respectively equipped with a first baffle 401, a second baffle 601, and a third baffle 901 on their sides. A first activated carbon adsorption tank 602 and a second activated carbon adsorption tank 902 are also respectively located on the other side of the second baffle 601 and the third baffle 901. Through holes are opened above the first baffle 401, the second baffle 601, and the third baffle 901. The activated carbon layers of the first activated carbon adsorption tank 602 and the second activated carbon adsorption tank 902 are located below the through holes of the second baffle 601 and the third baffle 901, respectively.This structure uses a first activated carbon adsorption tank 602 to adsorb and deodorize wastewater, allowing the wastewater entering the first biological filter 8 from the second advanced oxidation tank 6 to be deodorized. The inlet of the water distribution pipe 7 is inserted into the first activated carbon adsorption tank 602, and the inlet of the water distribution pipe 7 is located at the bottom of the activated carbon in the first activated carbon adsorption tank 602. This structure allows the wastewater to be evenly distributed within the first biological filter 8 through the water distribution pipe 7, ensuring effective wastewater treatment. The location of the inlet of the water distribution pipe 7 at the bottom of the activated carbon in the first activated carbon adsorption tank 602 allows the wastewater to be discharged after adsorption by the activated carbon. A water outlet pipe 903 is connected to the side of the second activated carbon adsorption tank 902, and the water outlet pipe 903 is located below the activated carbon layer in the second activated carbon adsorption tank 902. This structure further adsorbs and deodorizes the treated wastewater through the second activated carbon adsorption tank 902, providing the discharged wastewater with ultimate purification treatment.

[0018] Working Principle: When using this advanced oxidation and biological filter synergistic odor treatment device, wastewater first enters the filter cylinder 202 through the sewage inlet pipe 201, and then flows into the pretreatment tank 2 through the inlet baffle 203. The wastewater in the pretreatment tank 2 enters the first advanced oxidation tank 4, where the catalyst layer 13 oxidizes the wastewater. The first gas distribution pipe 14 provides ozone and other gases to the first advanced oxidation tank 4. Then, the wastewater flows through the through holes on the first baffle 401 into the second advanced oxidation tank 6, where the catalyst layer 13 again oxidizes the wastewater. Finally, the wastewater flows through the through holes on the second baffle 601 into the first activated carbon adsorption tank 602, where activated carbon adsorbs and removes odors. The cover plate 3 covers the pretreatment tank 2, the first advanced oxidation tank 4, and the second advanced oxidation tank 6, allowing the wastewater to pass through the first advanced oxidation tank 602 to remove odors. The waste gas generated after treatment in the primary oxidation tank 4 and the second advanced oxidation tank 6 is introduced into the second gas distribution pipe 15 through the exhaust pipe 5, and then evenly distributed into the first biological filter tank 8. Meanwhile, the water distribution pipe 7 evenly distributes the wastewater treated in the first activated carbon adsorption tank 602 into the first biological filter tank 8. The wastewater and waste gas undergo microbial degradation and purification treatment in the first biological filter tank 8 through the filter media layer 10. The purified waste gas is discharged and collected, while the wastewater enters the second biological filter tank 9 for secondary degradation treatment. The support layer 11 supports the filter media layer 10, and the support plate 12 is used to fix the support layer 11. The wastewater treated in the second biological filter tank 9 enters the second activated carbon adsorption tank 902 through the through hole on the third partition 901. After further purification, the wastewater is discharged through the outlet pipe 903, realizing the efficient treatment of wastewater by the main body of the treatment device 1, thereby completing a series of tasks.
