[0002] Anaerobic sewage treatment equipment is a device specially designed for treating sewage. It uses anaerobic bacteria (i.e. microorganisms that grow in the absence of oxygen or in conditions with extremely low oxygen content) to decompose organic matter in sewage. Anaerobic bacteria are a type of microorganism that grows and decomposes organic matter under anaerobic or anaerobic conditions. This equipment creates an environment suitable for the growth of anaerobic bacteria and uses the metabolic activities of anaerobic bacteria to convert organic matter in sewage into low molecular weight compounds, such as methane, carbon dioxide, etc., thereby achieving sewage purification.

[0003] During the treatment process, the existing anaerobic sewage treatment equipment often causes uneven reactions due to the sensitivity of anaerobic bacteria to water distribution uniformity, environmental conditions (such as temperature, pH value, nutrient concentration, etc.) and the type and concentration of organic matter in sewage. This uneven reaction will lead to low treatment efficiency and unstable effluent water quality. Utility Model Content

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a sewage treatment equipment using anaerobic bacteria, including a treatment box 1, a pretreatment tank 2 is provided inside the treatment box 1, an anaerobic tank 3 is provided inside the treatment box 1, a first water pump 4 is fixedly installed on the top of the treatment box 1, an input end of the first water pump 4 is fixedly connected with a water delivery pipe 5, and an output end of the pretreatment tank 2 is fixedly connected with an input end of the water delivery pipe 5, an output end of the first water pump 4 is fixedly connected with a delivery pipe 6, an outer surface wall of the delivery pipe 6 is fixedly connected with a group of nozzles 7, an inner surface wall of the anaerobic tank 3 is fixedly connected with a temperature sensor 8, and the anaerobic A heating tube 9 is fixedly installed on the inner wall of the pool 3, a stirring motor 10 is fixedly installed on the top of the processing box 1, and the output end of the stirring motor 10 is fixedly connected to the stirring shaft 11, and the outer wall of the stirring shaft 11 is fixedly sleeved with three mounting seats 12, and the outer walls of the three mounting seats 12 are fixedly connected to a group of stirring blades 13, one side of the outer wall of the processing box 1 is fixedly connected to a water outlet pipe 14, the output end of the water outlet pipe 14 is fixedly connected to a second water pump 15, and the output end of the second water pump 15 is fixedly connected to a reflux pipe 16, and one side of the outer wall of the processing box 1 is fixedly installed with a controller 17.

[0024] The effect achieved by the entire embodiment 1 is that after the equipment is powered on, the controller 17 first starts the first water pump 4, the first water pump 4 extracts the preliminarily treated sewage from the pretreatment tank 2, and then transports the sewage to a group of nozzles 7 through the delivery pipe 6. Under the action of the group of nozzles 7, the sewage is evenly sprayed to all corners of the anaerobic tank 3, thereby ensuring that the sewage is evenly distributed in the anaerobic tank 3 and improving the treatment efficiency. When the sewage accumulates to a certain depth in the anaerobic tank 3, the controller 17 immediately starts the stirring motor 10, and the output end of the stirring motor 10 drives the stirring shaft 11 to rotate, thereby driving the three mounting seats 12 to rotate, and the three mounting seats 12 respectively drive a group of stirring blades 13 fixedly connected to their outer walls to stir, and the stirring process promotes the full mixing of sewage and anaerobic bacteria, and strengthens the decomposition effect of organic matter. During the sewage treatment process in the anaerobic tank 3, the temperature sensor 8 continuously monitors the temperature in the tank. If the temperature does not reach the optimal reaction condition, the temperature sensor 8 will immediately send a signal to the controller 17. After receiving the signal, the controller 17 immediately starts the heating tube 9 for heating. The heat released by the heating tube 9 quickly diffuses to the entire anaerobic tank 3 under the stirring effect, ensuring that the temperature in the tank rises evenly and reaches the optimal reaction temperature of anaerobic bacteria, thereby accelerating the decomposition of organic matter. In addition, in order to ensure the full circulation and treatment effect of the sewage, the controller 17 will also start the second water pump 15. The second water pump 15 draws sewage from the bottom of the anaerobic tank 3 and re-sends it into the anaerobic tank 3 through the reflux pipe 16 to realize the circulation of the sewage. This circulation process helps to maintain the uniformity and activity of the sewage in the tank and further improve the treatment efficiency.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, one side of the outer wall of the treatment box 1 is fixedly connected with a water inlet pipe 18, one side of the outer wall of the treatment box 1 is provided with two slide grooves 19, a sliding cabinet 20 is slidably embedded between the inner walls of the two slide grooves 19, a grille 21 is fixedly connected between the inner walls of the sliding cabinet 20, a handle 22 is fixedly installed on one side of the outer wall of the sliding cabinet 20, a filter screen 23 is fixedly connected between the inner walls of the pretreatment tank 2, a partition plate 24 is fixedly connected between the inner walls of the pretreatment tank 2, and the outer wall of the treatment box 1 is fixedly connected with a drain pipe 25, and a drain valve 26 is arranged inside the drain pipe 25.

[0026] The effect achieved by the entire embodiment 2 is that the sewage first flows into the pretreatment tank 2 through the water inlet pipe 18. In the process of the sewage entering the pretreatment tank 2, it will first pass through the grille 21. The interception structure set on the surface of the grille 21 can effectively remove the coarse suspended matter and floating matter in the sewage to prevent them from entering the subsequent treatment process. The grille 21 is designed to be inclined, which not only increases the interception area, but also effectively prevents the accumulation of debris on the grille 21, maintaining its good filtering effect. The grille 21 is fixedly installed between the inner surface walls of the sliding cabinet 20. When the grille needs to be cleaned 21, just pull the handle 22 to slide out the sliding cabinet 20, you can easily slide out the sliding cabinet 20, so that the intercepted objects can be conveniently cleaned and processed, a filter screen 23 is fixedly connected between the inner surface walls of the pretreatment tank 2, and a partition 24 is fixedly connected between the inner surface walls of the pretreatment tank 2. The partition 24 allows the sewage to pass upward only through the bottom of the filter screen 23, so that it can be ensured that the sewage extracted by the first water pump 4 is preliminarily treated, and it also avoids a group of nozzles 7 from being blocked by impurities in the sewage, ensuring the normal operation of the equipment and the sewage treatment efficiency.

[0027] Working principle: After the equipment is powered on, the sewage first flows into the pretreatment tank 2 through the water inlet pipe 18. In this process, the grille 21 serves as the first line of defense. The interception structure designed on its surface effectively intercepts the coarse suspended solids and floating objects in the sewage to prevent them from continuing to enter the subsequent treatment links. The grille 21 adopts a slope design, which not only expands the interception area, but also prevents the accumulation of debris and maintains an efficient filtering effect. The grille 21 is fixedly installed between the inner surface walls of the sliding cabinet 20. When cleaning is required, the sliding cabinet 20 can be easily slid out by simply pulling the handle 22, which is convenient. The grid 21 is cleaned, and then the design of the partition 24 ensures that the sewage can only flow upward through the bottom of the filter 23 to achieve further filtration and purification. At this time, the controller 17 starts the first water pump 4, and the first water pump 4 extracts the preliminarily treated sewage from the pretreatment tank 2 through the water delivery pipe 5 located above the filter 23. The sewage is transmitted through the delivery pipe 6 and delivered to a group of nozzles 7. The function of the nozzle 7 enables the sewage to be evenly sprayed to every corner of the anaerobic tank 3, ensuring the uniform distribution of the sewage in the tank, thereby improving the overall treatment efficiency. As the sewage accumulates in the anaerobic tank 3, when it reaches a certain depth, the controller 17 will automatically start the stirring motor 10, and the stirring motor 10 drives the stirring shaft 11 to rotate, thereby driving the three sets of stirring blades 13 to rotate and stir. This stirring process effectively promotes the mixing of sewage and anaerobic bacteria, and strengthens the decomposition effect of organic matter. During the entire sewage treatment process, the temperature sensor 8 always monitors the temperature in the anaerobic tank 3. Once it is found that the temperature does not reach the optimal reaction condition, the temperature sensor 8 will immediately send a signal to the controller 17, and then the controller 17 starts the heating tube 9 for heating. Under the action of the stirring blades 13, the heat released by the heating tube 9 quickly spreads to the entire anaerobic tank 3, ensuring that the temperature in the tank rises evenly, creating the best reaction environment for anaerobic bacteria, and accelerating the decomposition of organic matter. In addition, in order to further improve the treatment effect, the controller 17 will also start the second water pump 15, and the second water pump 15 will extract sewage from the bottom of the anaerobic tank 3 and send it back into the tank through the reflux pipe 16 to achieve the circulation of sewage. This circulation process helps to maintain the uniformity and activity of the sewage in the tank, and further improve the overall treatment efficiency.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
