Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a household non-powered biochemical wastewater treatment and resource utilization system. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] Rural households in the hilly and mountainous areas of western and southern China are scattered, making it difficult to collect sewage centrally. Furthermore, most households lack complete sewage collection pipelines and corresponding treatment facilities, resulting in the direct discharge of untreated sewage. This sewage has high nitrogen and phosphorus content, causing environmental pollution. The dispersed nature of rural areas also presents numerous challenges for rural domestic sewage treatment, including high investment in pipeline construction, high operation and maintenance costs, and ineffective treatment. While individual household treatment is preferable, currently used integrated equipment is typically employed in areas with large sewage volumes. This often results in high investment costs, high operating expenses, and complex operation and management. There are few integrated sewage treatment systems widely applicable to individual households or agritourism businesses. To address these technical issues, we have designed a household-use, non-powered biological sewage treatment and resource utilization system. Utility Model Content

[0004] The purpose of this utility model is to provide a household non-powered biochemical sewage treatment and resource utilization system, which has the advantages of easy operation, good effect and low cost, and solves the problems of large investment in pipeline construction, high operation and maintenance costs and insignificant treatment effect in rural domestic sewage treatment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a household non-powered biochemical sewage treatment and resource utilization system, comprising a base and anaerobic fermentation material.

A liquid level sensor is installed through the right side of the base, and a biogas detection sensor is installed through the surface of the exhaust pipe. The liquid addition mechanism includes a liquid addition pipe, which is connected and installed on the left side of the base. The flow mechanism includes a connecting pipe, which is installed through the surface of the partition plate.

A shell 2 is fixedly installed on the top of the base 1, and a partition plate 3 is fixedly installed in the inner cavity of the shell 2. A flow mechanism 4 is provided on the surface of the partition plate 3. A flipping rod 6 is installed through the rear side of the base 1. A liquid addition mechanism 7 is provided on the left side of the base 1. A cover plate 8 is movably installed on the top of the partition plate 3. An exhaust pipe 9 is installed through the top of the cover plate 8. A liquid level sensor 11 is installed through the right side of the base 1. A biogas detection sensor 10 is installed through the surface of the exhaust pipe 9. The liquid addition mechanism 7 includes a liquid addition pipe 13, which is connected to the left side of the base 1. The flow mechanism 4 includes a connecting pipe 21, which is installed through the surface of the partition plate 3. The exhaust pipe 9 facilitates the discharge of biogas generated in the equipment. The biogas detection sensor 10 can detect the biogas discharged in the exhaust pipe 9 to prevent biogas from being not discharged. The liquid level sensor 11 can monitor the amount of stored wastewater.

[0020] Please see Figure 1 and Figure 2 Anaerobic fermentation material 5 is filled into the inner cavity of shell 2. A drain valve 12 is connected to the rear side of shell 2. By setting the drain valve 12, it is easy to discharge the sewage stored in the equipment.

[0021] Please see Figure 2 and Figure 3 A positioning groove 14 is provided on the left side of the liquid filling pipe 13. A filter grid cylinder 15 is movably installed in the inner cavity of the liquid filling pipe 13. Positioning plates 16 are fixedly connected to both sides of the filter grid cylinder 15. By setting the positioning plates 16, the filter grid cylinder 15 can be positioned so that the filter grid cylinder 15 can be installed into the liquid filling pipe 13.

[0022] Please see Figure 3A fixed frame 17 is fixedly installed on the top of the liquid filling tube 13. A fixed bracket 18 is movably installed in the inner cavity of the fixed frame 17. A spring 19 is fixedly installed in the inner cavity of the fixed frame 17. By setting the spring 19, the fixed bracket 18 can be pushed to prevent the limit plate 20 from falling out of the positioning groove 14 at will.

[0023] Please see Figure 3 The right side of the spring 19 is fixedly connected to the fixing frame 18. Both sides of the fixing frame 18 extend to the outside of the fixing frame 17 and are fixedly connected to the limiting plate 20. By setting the limiting plate 20, the positioning plate 16 can be limited and fixed to prevent the filter grid cylinder 15 from falling out of the liquid filling pipe 13.

[0024] Please see Figure 1 and Figure 4 The front and rear sides of the connecting pipe 21 are fixedly connected with mounting frames 22, and the top of the connecting pipe 21 is installed with a filter grid plate 23. The top of the filter grid plate 23 is fixedly connected with a connecting frame 24. By setting the connecting pipe 21, sewage flows into the equipment by gravity.

[0025] Please see Figure 1 and Figure 4 The bottom of the filter grid plate 23 is fixedly connected with a positioning rod 26, and both sides of the bottom of the connecting frame 24 are fixedly connected with mounting buckles 25. By setting the positioning rod 26, the filter grid plate 23 can be positioned, thereby increasing the stability of the filter grid plate 23 installation. Through the cooperation of the mounting frame 22 and the mounting buckles 25, the filter grid plate 23 can be limited and fixed by the connecting frame 24 to prevent the filter grid plate 23 from falling out of the connecting pipe 21.

[0026] During use, the user can open the cover plate 8 to add the precipitating agent and anaerobic fermentation material into the shell 2. Then, the user introduces wastewater into the shell 2 through the liquid addition pipe 13. When the wastewater enters the shell 2, the filter screen 15 will intercept large-volume impurities in the wastewater to prevent them from entering the equipment. After entering the shell 2, the wastewater will first undergo sedimentation, allowing it to react with the precipitating agent and settle impurities. During sedimentation, the user can also rotate the agitator 6 to ensure the precipitating agent reacts fully with the wastewater, thereby accelerating the sedimentation process. After sedimentation, the wastewater will flow by gravity into the anaerobic fermentation material through the connecting pipe 21. During this flow, the filter screen 23 will filter and intercept the wastewater, preventing impurities from entering the anaerobic fermentation material. Then, the anaerobic bacteria in the anaerobic fermentation material will decompose the organic matter in the wastewater. Large organic molecules in the wastewater will be degraded into smaller organic molecules by specialized bacteria, effectively removing nitrogen and phosphorus, and producing a small amount of biogas. The gas is discharged through the exhaust pipe 9, reducing odor pollution and achieving the effect of purifying water quality. At the same time, the anaerobic fermentation material contains ceramsite filler, which makes the fermentation bacteria more evenly distributed throughout the equipment, forming a highly efficient anaerobic biological filter membrane, achieving the effect of rapid sewage treatment. When biogas is discharged, the biogas detection sensor 10 will detect the biogas in real time. The purified sewage will flow through the connecting pipe 21 to the right side of the equipment for storage, so that the treated sewage can be collected and used by farmers for resource utilization. During long-term use, the user can pull the spring 19 through the fixing bracket 18 to release the restriction on the positioning plate 16. Then, the user can pull the positioning plate 16 out of the positioning groove 14 and rotate it to remove the filter grid cylinder 15. Then, the user can press the mounting buckle 25 to release the restriction on the connecting frame 24, so that the user can remove the filter grid plate 23 from the connecting pipe 21 for replacement of the filter grid cylinder 15 and the filter grid plate 23.

[0027] In summary, this household non-powered biochemical sewage treatment and resource utilization system, through the cooperation of base 1, shell 2, partition plate 3, flow mechanism 4, anaerobic fermentation material 5, turning rod 6, liquid addition mechanism 7, cover plate 8, exhaust pipe 9 and biogas detection sensor 10, solves the problems of large investment in pipeline construction, high operation and maintenance costs and insignificant treatment effect in rural domestic sewage treatment.
