[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] Embodiment: The utility model provides an integrated sulfur autotrophic denitrification sewage treatment device, see Figure 1-Figure 5 As shown, it includes a base 1, a sewage treatment tank 2, a top cover 3, an inlet pipe 4, a drain pipe 6, a guide pipe 40, a guide ring plate 7, a filter assembly and a scraper. The sewage treatment tank 2 is arranged on the upper part of the base 1, and the top cover 3 is arranged on the top of the sewage treatment tank 2. The side wall of the top cover 3 is connected and communicated with the inlet pipe 4, and the middle of the bottom of the sewage treatment tank 2 is connected and communicated with the drain pipe 6. A guide ring plate 7 is arranged between the bottom and the inner wall of the sewage treatment tank 2, and the guide ring plate 7 divides the interior of the sewage treatment tank 2 into a circulating waterway. The guide ring plate 7 is designed with a flat spiral structure, which is conducive to guiding the sewage along a specific path. The guide ring plate 7 is connected and communicated with the water inlet pipe 4 by a guide pipe 40. The outlet of the guide pipe 40 is located above the entrance of the circulating waterway, which is conducive to allowing the connected sewage to flow along the path of the circulating waterway. The guide pipe 40 is designed with a vortex structure that is narrow at the top and wide at the bottom, which is conducive to increasing the flow potential energy of the sewage. A filter component is arranged in the middle of the bottom of the sewage treatment tank 2, and the filter component includes a filter The filter cartridge 5, the filter disc 50, the pull rod 11 and the observation window 10 are provided in the middle of the bottom of the sewage treatment tank 2, and the filter cartridge 5 is located at the center of the circulating waterway. The bottom of the filter cartridge 5 is connected and communicated with the drain pipe 6. The inner bottom of the filter cartridge 5 is slidably clamped with the filter disc 50. The filter layers a of different filter materials are stacked between the filter disc 50 and the filter cartridge 5. The circulating waterway allows the sewage to flow in a circular manner, which is beneficial to improve the fluidity of the water body and prevent impurities in the water body from directly adhering to the filter cartridge 5. The problem of clogging caused by the outer wall or filter layer a is solved. The pull rod 11 passes through the filter layer a and is threadedly connected to the middle of the filter disc 50. The top of the top cover 3 is embedded with an observation window 10, and the pull rod 11 is movably connected to the observation window 10. Through the sealing connection of the sewage treatment tank 2, the top cover 3 and the observation window 10, the sewage treatment tank 2 can maintain an anaerobic sealed state, which is beneficial to the treatment of sewage under anaerobic conditions using sulfur autotrophic denitrification technology. A scraper is arranged on the outer wall of the filter cartridge 5.

[0021] See also Figure 2-Figure 5 As shown, further, the scraper includes a swivel 8 and a scraper strip 9. The swivel 8 is connected to the port on the upper part of the filter cartridge 5 through a bearing.

[0023] When in use, the sewage is connected to the sewage treatment tank 2 through the water inlet pipe 4. Under the guidance of the guide pipe 40 and the guide ring plate 7, the discharged sewage is guided and flows in a vortex along the circulating waterway. This vortex flow structure helps to initially disperse the suspended matter, particulate matter, etc. in the sewage, providing favorable conditions for subsequent filtration treatment; and during the vortex flow process, the sewage can be filtered and purified through the stacked and layered filter layers a in the filter cartridge 5. These filter layers a are composed of filter media of different materials, which can gradually remove impurities, suspended matter and organic matter in the sewage, thereby achieving the purpose of purifying the sewage. The purified sewage will be discharged through the drain pipe 6; and through the circulating waterway Under the push of the internal sewage, the scraper bar 9 and the rotating ring 8 can be driven to rotate, so that the scraper bar 9 can scrape and clean the impurities attached to the outer wall of the filter cartridge 5, which is beneficial to avoid the accumulation of impurities and the clogging of the filter holes of the filter cartridge 5, thereby affecting the sewage filtration efficiency; when the filter layer a of the filter cartridge 5 needs to be replaced regularly, it is only necessary to open the observation window 10 and pull the handle 12 and lift the pull rod 11, the filter disc 50 and the filter layer a upwards, and then remove the pull rod 11 from the filter disc 50 to achieve the purpose of convenient replacement of the filter layer a. After the replacement is completed, it is only necessary to reset the filter layer a, the filter disc 50 and the pull rod 11, and close the observation window 10 to complete the entire replacement process.
