[0036] The purpose of the utility model is to overcome the defects of the prior art and provide a sewage treatment device to solve the problem that when the existing equipment is used to treat sewage, the sewage treatment device is large in size and easily causes sewage to be retained, and a small part of the sewage cannot be fully purified in the treatment box, which greatly reduces the efficiency of sewage treatment and the sewage purification rate cannot be improved. By arranging an air transmission mechanism in the shell that contains sewage, the sewage is circulated and rolled in the shell, avoiding the retention of sewage in the corners of the shell, improving the purification rate and purification efficiency of the sewage in the shell, and ensuring that the sewage is fully purified.

[0037] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] See also Figure 1 , showing a stereoscopic diagram of a sewage treatment device of the utility model.

[0039] like Figure 1 As shown, a sewage treatment device of the present invention includes: a shell 21 and a gas transmission mechanism 31. The shell 21 is a main body, and a containing space is formed inside the shell for accommodating sewage to be treated. The shell 21 needs to have good sealing performance to prevent sewage leakage. The shell 21 is provided with an inlet pipe and an outlet pipe on the opposite side. The sewage enters the shell 21 from the inlet pipe, and is output to the outside of the shell 21 from the outlet pipe after purification. The gas transmission mechanism 31 is installed on the outside of the shell 21, and the gas transmission mechanism 31 is connected with the inside of the shell 21. The gas transmission mechanism 31 transmits gas to the shell 21, and different gases can be transmitted according to the composition of the sewage in the shell 21 to improve the purification rate of sewage with different components.

[0040] By delivering gas into the shell 21, the content of oxygen and other gases in the sewage can be increased, which helps to promote the growth and metabolism of microorganisms, thereby improving the biological treatment efficiency of the sewage.

[0041] At the same time, the gas is input into the shell 21 through the gas transmission mechanism 31, driving the sewage in the shell 21 to tumble. The stirring effect of the gas can also help break up the aggregation of suspended matter and particulate matter in the sewage, increase its contact area with the treatment agent or microorganisms, and further improve the treatment effect.

[0042] See also Figure 2 , showing a cross-sectional view of a sewage treatment device of the utility model.

[0043] Combination Figure 1 and Figure 2 As shown, in a preferred embodiment of the sewage treatment equipment of the present invention, the gas delivery mechanism 31 includes: a driving member 32, a gas delivery pipe 33;

[0044] The driving member 32 is disposed outside the housing 21 to ensure its stability during operation and convenience of maintenance. The driving member 32 is provided with an output end for outputting gas. Specifically, the driving member 32 is a blower.

[0045] The gas pipe 33 runs through the shell 21, and delivers the gas generated by the driving member 32 to the interior of the shell 21. One end is connected to the output end, and the other end is connected to the interior of the shell 21. The gas enters the interior of the shell 21 through the gas pipe 33, and contacts and acts on the sewage. Through the combination of the driving member 32 and the gas pipe 33, it can be ensured that the process of gas delivery to the interior of the shell 21 is efficient and stable. The design of the gas delivery mechanism 31 makes the entire device compact, reduces the floor space, and is suitable for sewage treatment sites of various sizes. The installation and maintenance of the driving member 32 and the gas pipe 33 are relatively simple, which reduces the maintenance cost of the equipment.

[0046] Preferably, in a preferred embodiment of the sewage treatment equipment of the present invention, an isolation plate 213 is provided in the shell 21, and the isolation plate 213 divides the internal space of the shell 21 into two interconnected parts, namely, a first accommodating chamber and a second accommodating chamber 223, so that the two chambers can perform different operations and treatments respectively during the sewage treatment process.

[0047] The water inlet pipe is connected to the first accommodating chamber to introduce the sewage to be treated into the chamber, and the gas transmission mechanism 31 is connected to the first accommodating chamber to perform preliminary contact and mixing of sewage and gas. After being treated in the first accommodating chamber, the sewage is introduced into the second accommodating chamber 223 for further purification. The water outlet pipe is connected to the second accommodating chamber 223 to discharge the treated sewage. The second accommodating chamber 223 performs further treatment, such as sedimentation, filtration, etc., to achieve higher water quality standards. Through the design of the isolation plate 213, the treatment process is divided into different stages, so that each stage can focus more on its specific treatment task, thereby improving the overall treatment efficiency.

[0048] The compartmentalized design makes the operation of each chamber relatively independent, which is convenient for monitoring and management. By observing the treatment status of each chamber, the treatment parameters can be flexibly adjusted or other measures can be taken to meet different treatment requirements. Specifically, the gas content of the first accommodating chamber can be changed by adjusting the parameters of the gas transmission mechanism 31 to adapt to sewage of different concentrations.

[0049] Specifically, a first water pump 224 and a first connecting pipe 225 are provided. The first water pump 224 is arranged at the bottom of the first accommodating chamber. One end of the first connecting pipe 225 is arranged in the first accommodating chamber, and the other end is arranged in the second accommodating chamber 223. After the sewage in the first accommodating chamber is purified, it is pumped into the second accommodating chamber 223 for further purification.

[0050] Furthermore, in a preferred embodiment of the sewage treatment equipment of the present invention, a separation plate 213 is also provided in the first containing chamber, and based on the basic principle of biological treatment in sewage treatment, the first containing chamber is subdivided into an anaerobic tank 221 and an aerobic tank 222.

[0051] The water inlet pipe is connected to the anaerobic tank 221. In the anaerobic tank 221, microorganisms carry out metabolic activities in the absence of oxygen, mainly decomposing macromolecular organic matter and removing some pollutants.

[0052] The aerobic tank 222 is connected to the second containing chamber 223, and the gas supply mechanism 31 is connected to the aerobic tank 222. The sewage after anaerobic treatment then enters the aerobic tank 222. The microorganisms in the aerobic tank 222 metabolize in an aerobic environment, further decompose organic matter and remove remaining pollutants. Gas, usually air, is delivered to the aerobic tank 222 through the gas pipe 33, which ensures the oxygen supply required for the normal metabolic activities of the microorganisms in the aerobic tank 222 and promotes the biological treatment process of the sewage. The water treated in the aerobic tank 222 will enter the second containing chamber 223 for subsequent treatment or discharge.

[0053] Specifically, the sewage treatment equipment of the present invention is also provided with a second water pump 226 and a second connecting pipe 227. In the present embodiment, the first water pump 224 is arranged at the bottom of the anaerobic tank 221, one end of the first connecting pipe 225 is arranged at the anaerobic tank 221, and the other end is arranged at the aerobic tank 222, the second water pump 226 is arranged at the bottom of the aerobic tank 222, one end of the second connecting pipe 227 is arranged at the aerobic tank 222, and the other end is arranged at the second accommodating chamber 223. After the sewage in the aerobic tank 222 is purified, it is pumped into the second accommodating chamber 223 for further purification treatment.

[0054] The separation design of the anaerobic tank 221 and the aerobic tank 222 enables the biological treatment of the two stages to be carried out separately, optimizes the treatment conditions, and improves the treatment efficiency. The anaerobic tank 221 mainly removes easily degradable organic matter, creating a more favorable environment for the treatment of the aerobic tank 222. It can adapt to the changes in different water quality and treatment requirements. By adjusting the parameters of the gas transmission mechanism 31, the oxygen content in the aerobic tank 222 can be controlled to meet the microbial requirements under different treatment conditions and maintain the stability of the treatment effect.

[0055] Preferably, in a preferred embodiment of the sewage treatment equipment of the present invention, the top of the shell 21 is open, and a top cover 212 is detachably provided on the top of the shell 21, and the shell 21 is used to accommodate the sewage to be treated and various reactions for sewage treatment. The shell 21 is usually made of corrosion-resistant and wear-resistant materials to ensure its stability and reliability in long-term use. The top cover 212 is detachably covered on the shell 21 to form a closed sewage treatment environment. The detachable top cover 212 should not only prevent the leakage of sewage and the entry of external impurities, but also facilitate the maintenance and overhaul of the equipment by the staff, while ensuring the sealing and ease of operation. Specifically, the detachable connection is achieved by bolts, buckles or other fasteners to ensure the firmness and sealing of the connection. Other equivalent and alternative connection methods are also within the scope of protection of the utility model and will not be repeated here.

[0056] During the sewage treatment process, some dirt or sediment may accumulate inside the equipment. The detachable top cover 212 design makes cleaning easier, and the inside of the housing 21 can be easily entered for thorough cleaning to ensure the long-term stable operation of the equipment. Regularly opening the top cover 212 for maintenance and overhaul can timely discover and solve problems and hidden dangers that may occur during the operation of the equipment, thereby ensuring the normal operation and safety of the equipment.

[0057] See also Figure 4 , showing an enlarged view of part B of a sewage treatment equipment of the present utility model.

[0058] like Figure 3 As shown, further, in a preferred embodiment of the sewage treatment equipment of the present invention, the sewage treatment equipment fixing frame, one end of the fixing frame is fixed to the outer side of the top of the shell 21, and can be firmly fixed to the outer side of the top of the shell 21 by welding, bolts or other methods. The other end is detachably connected to the top of the top cover 212, and is achieved by bolts, buckles or other fasteners, ensuring that the top cover 212 can be firmly fixed to the shell 21 and can be easily removed.

[0059] When the top cover 212 is installed on the housing 21, the fixing frame supports and fixes the top cover 212, so that the top cover 212 can stably cover the housing 21, forming a closed sewage treatment environment, effectively preventing the top cover 212 from loosening, shifting or falling off during use, and ensuring the safe operation of the equipment. At the same time, since the fixing frame and the top cover 212 are detachably connected, the top cover 212 can be easily removed when necessary to perform maintenance, inspection or cleaning of the equipment.

[0060] Preferably, in a preferred embodiment of the sewage treatment equipment of the present invention, the fixing frame includes: an L-shaped rod 231 , a horizontal rod 232 and a supporting bolt 233 .

[0061] One end of the L-shaped rod 231 is fixedly connected to the shell 21, and the other end of the L-shaped rod 231 is rotatably connected to a horizontal rod 232, so as to adjust the position and angle of the horizontal rod 232. The other end of the horizontal rod 232 is provided with a threaded hole, and the end of the horizontal rod 232 provided with the threaded hole can be rotated to the top of the top cover 212, and the supporting bolt 233 is threadedly connected to the threaded hole. The supporting bolt 233 can be screwed downward and supported on the top of the top cover 212. When the horizontal rod 232 is rotated to the top of the top cover 212, the supporting bolt 233 can be threadedly connected in the threaded hole and supported downward on the top of the top cover 212 through a rotation operation.

[0062] The rotatable connection between the L-shaped rod 231 and the horizontal rod 232 and the threaded connection between the top support bolt 233 and the horizontal rod 232 make the installation and removal process of the entire fixing frame simple and quick. The horizontal rod 232 can be easily rotated to a suitable position and fixed with the top support bolt 233 without using complicated tools or performing cumbersome operations.

[0063] The horizontal rod 232 can rotate relative to the L-shaped rod 231, and the top support bolt 233 can be adjusted up and down in the threaded hole, and the fixing frame has high adaptability and flexibility. No matter how the shape, size or position of the top cover 212 changes, it can be adapted by adjusting the position and angle of the horizontal rod 232 and the top support bolt 233 to ensure that the top cover 212 can be firmly fixed on the housing 21. When it is necessary to maintain or overhaul the equipment, the top cover 212 can be removed by simply loosening the top support bolt 233, thereby improving work efficiency.

[0064] Furthermore, in a preferred embodiment of the sewage treatment equipment of the present invention, a plurality of nozzles 34 are provided at one end of the air supply pipe 33 away from the driving member 32 .

[0065] The main function of the gas pipe 33 is to deliver gas, usually oxygen or air, to a specific area in the sewage treatment equipment to meet the oxygen demand in the biological treatment process. The nozzle 34, as the output port of the gas pipe 33, is responsible for evenly and finely dispersing the gas into the sewage to be treated. Specifically, after the gas enters the gas pipe 33 through the driving member 32, as the gas flows, it eventually reaches the far end of the gas pipe 33, that is, the part where the nozzle 34 is provided. These nozzles 34 are usually designed as small holes or nozzles. When the gas flows through these nozzles 34, due to the reduction of the aperture and the increase of the gas flow rate, the gas is dispersed into fine bubbles and evenly sprayed into the sewage.

[0066] By dispersing the gas into tiny bubbles through the nozzle 34, the contact area between the gas and the sewage can be increased, thereby improving the dissolution and utilization rate of oxygen and avoiding local oxygen excess or deficiency. This helps to provide more sufficient oxygen for microorganisms during the biological treatment process, promote their metabolic activities, and improve sewage treatment efficiency.

[0067] The spray head 34 is a detachable and replaceable component, which makes installation and maintenance work relatively simple. When the spray head 34 is blocked or damaged, it can be easily replaced to ensure the normal operation of the equipment.

[0068] According to different treatment requirements and sewage characteristics, the number, aperture and distribution of the nozzles 34 can be adjusted to adapt to different treatment conditions.

[0069] Preferably, in a preferred embodiment of the sewage treatment equipment of the present invention, a fixing groove 242 is provided at the top of the side wall of the shell 21, and a fixing block 241 is provided at the bottom of the top cover 212 corresponding to the fixing groove 242. The shape and size of the fixing groove 242 match the fixing block 241 so that the fixing block 241 can be smoothly embedded therein. The depth and width of the fixing groove 242 must meet the strength requirements to ensure that the fixing block 241 can be firmly fixed in the groove. The shape and size of the fixing block 241 are adapted to the fixing groove 242 so that when the top cover 212 is placed on the shell 21, the fixing block 241 can be accurately embedded in the fixing groove 242.

[0070] When the top cover 212 is placed on the housing 21, the fixing block 241 will gradually fit into the fixing groove 242 as the top cover 212 moves downward. As the fixing block 241 is fully embedded, the connection between the top cover 212 and the housing 21 becomes stable, thereby achieving the fixation of the top cover 212. No additional fasteners or tools are required, and a firm fixation can be achieved by simply matching the fixing block 241 with the fixing groove 242. The installation can be completed by simply placing the top cover 212 on the housing 21 and embedding the fixing block 241 in the fixing groove 242. Similarly, when removing, the top cover 212 can be lifted from the housing 21 to disengage the fixing block 241 from the fixing groove 242.

[0071] See also Figure 3 , showing an enlarged view of part A of a sewage treatment equipment of the utility model.

[0072] like Figure 3 As shown, specifically, the inner side surface of the fixing groove 242 is provided with a rib 243 and a stopper 245, the rib 243 is provided at the top of the inner side surface of the fixing groove 242, the surface of the rib 243 is also provided with a protrusion 244, the stopper 245 is provided at the bottom of the inner side surface of the fixing groove 242, the surface of the protrusion 244 and the surface of the stopper 245 are located on the same straight line, the rib 243 and the stopper 245 are both rectangular structures, the protrusion 244 is a trapezoidal structure, when the disassembled top cover 212 is installed, the fixing block 241 is inserted into the interior of the positioning groove along the rib 243 and the protrusion 244, and the positioning block abuts against the stopper 245, thereby providing positioning for the fixing block 241 during installation.

[0073] Furthermore, in a preferred embodiment of the sewage treatment equipment of the present invention, the top cover 212 is provided with an openable and closable feeding port 251. The feeding port 251 is used to feed required materials, such as pharmaceuticals, biological agents or other treatment materials, into the sewage treatment equipment. An opening and closing mechanism, such as a door, a cover or a valve, is provided to ensure that it can be conveniently opened when feeding and can be tightly closed when not feeding.

[0074] Specifically, a feeding meter 252 is installed on the inner side of the feeding port 251 for monitoring the feeding amount, and the material can be directly fed into the equipment through the feeding port 251 without disassembling other components or moving the equipment, which greatly improves the efficiency of the feeding operation and reduces the labor cost and time cost.

[0075] The feeding port 251 can maintain the airtightness of the sewage treatment equipment when closed, preventing external impurities, dust or other pollutants from entering the interior of the equipment, which helps to maintain the cleanliness and treatment effect inside the equipment, while reducing the risk of equipment failure caused by external contamination.

[0076] By providing an opening and closing mechanism and a locking device, the feeding port 251 can be kept closed when not in use to prevent accidental opening or mistaken entry by personnel, which helps to improve the safety of the equipment and reduce safety risks caused by improper operation or accidents.

[0077] Furthermore, in one embodiment, a controller and an alarm locator are installed on the front surface of the shell 21. The controller is used to turn on the alarm locator. The alarm locator monitors the operating status of the sewage treatment equipment. If any problem is found in the operation, an alarm will be issued, further increasing the convenience of use.

[0078] The following is a further description of the method of using the sewage treatment equipment of the present utility model in conjunction with the accompanying drawings.

[0079] Open the feeding port 251 on the top cover 212, and put the required medicines, biological agents or other treatment materials into the equipment. After the feeding is completed, ensure that the feeding port 251 is tightly closed to maintain the airtightness of the equipment. Open the water inlet pipe, adjust the water inlet and the first water pump 224 and the second water pump 226 to control the residence time and concentration of the sewage in the anaerobic tank 221, the aerobic tank 222 and the second containing chamber 223 to ensure that the treatment effect reaches the best state. At the same time, turn on the blower and the alarm locator to deliver air or other gases to the aerobic tank 222, and monitor the operation of the equipment. Finally, detect the effluent quality to ensure that it meets the discharge standards.

[0080] The utility model is described in detail above in conjunction with the embodiments of the drawings.
