Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated device for treating domestic sewage in towns and villages. Background Art

[0002] Rural domestic sewage treatment is to remove harmful substances and environmental pollutants in domestic sewage, degrade them and make them harmless. Rural sewage treatment can neutralize water quality and agricultural products according to actual conditions, so as to achieve reuse or environmentally friendly degradation and discharge.

[0003] A sewage treatment integrated device disclosed in Chinese patent publication number CN220432559U provides an ideal habitat for microorganisms through a filler layer, and the microorganisms can form biofilms on the filler surface. These biofilms are constantly renewed and thickened, which helps to improve the sewage treatment efficiency.

[0004] However, compared with the existing technologies in the related fields, when the equipment is continuously treating sewage, the microorganisms inside the packing layer will gradually be lost as the working time increases. Microorganisms are a key factor in sewage treatment, and they are responsible for decomposing and removing organic matter in the water. If the microorganisms inside the packing layer are missing, the biological treatment efficiency will be directly reduced, resulting in a decrease in the removal rate of organic matter. In addition, the existing equipment cannot add microorganisms or clean the packing layer during the water treatment process. Therefore, it is necessary to shut down the equipment and empty the internal medium before adding microorganisms or cleaning the packing layer. This makes the process of adding microorganisms or cleaning the packing layer time-consuming and labor-intensive, affecting the normal operation of the equipment. Utility Model Content

DETAILED DESCRIPTION

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0024] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0025] like Figures 1 to 6As shown, an integrated device for treating domestic sewage in towns and villages comprises a tank body 1, an aeration area 2 is arranged inside the tank body 1, separation areas 3 are arranged on both sides of the aeration area 2 of the tank body 1, and a filler assembly 4 is arranged near the top of the separation area 3; the filler assembly 4 comprises a shell 401 fixedly installed inside the separation area 3, a notch 402 is longitudinally penetrated through the outer surface of the shell 401, arc baffles 403 are movably connected at positions corresponding to the two notches 402 on the inner wall of the shell 401, and arc baffles 403 are opened at positions corresponding to the two baffles of the shell 401 The arc chute 404 is used to control the arc baffle 403 to rotate around the axis of the shell 401. A cage 405 is provided inside the shell 401 for rotation. A packing layer 406 is provided inside the cage 405. When the sewage enters the cage 405 through the slot 402 of the shell 401, the sewage will contact the Klebsiella inside the packing layer 406, so as to remove nitrogen and phosphorus in the sewage to the maximum extent. The treated sewage will be discharged through the opening above the separation area 3. Both baffles are provided with a joint component 5 linked to the cage 405.

[0026] like Figure 1 As shown, a submersible pump 6 is installed inside the aeration area 2, and a plurality of pipelines 601 are provided at the output end of the submersible pump 6. A shock wave mass transfer device 602 is installed at the outlet of the pipeline 601, and the inlet of the pipeline 601 extends to the outside of the tank body 1. A plurality of agitators 7 are installed near the bottom of the aeration area 2. Both separation areas 3 are connected to the aeration area 2, and three-phase separators 8 are installed near the two separation areas 3 connected to the aeration area 2. Both sides of the bottom of the tank body 1 are provided with sewage pipes 9, and both sewage pipes 9 penetrate the tank body 1 and the separation area 3 and extend to the inside of the aeration area 2. The sewage pipes 9 are provided to regularly discharge the sludge precipitated inside the tank body 1. At the same time, by adjusting the exposure or stop ratio, a multi-stage aerobic, anoxic or anaerobic state is created in the reaction tank, so that the sewage is in the best denitrification and phosphorus removal working condition in the reactor, thereby removing nitrogen and phosphorus in the sewage to the maximum extent.

[0027] like Figures 2 to 7As shown, the linkage component 5 includes a linkage block 501, and two arc-shaped baffles 403 are each provided with an installation groove 502. The interior of the two installation grooves 502 is hingedly matched with the linkage block 501. The linkage block 501 is hingedly arranged inside the installation groove 502 through an elastic member shaft 503, and a rubber layer is fixedly provided on the outer surface of the linkage block 501. One end of the rotating cage 405 is closed, and a cage cover 10 is fixedly installed at the opening of the rotating cage 405. A handle 11 is fixedly installed on the side of the cage cover 10 away from the rotating cage 405. The handle 11 rotates the cage cover 10 clockwise, and at this time, the arc-shaped baffle 403 is controlled by the arc-shaped slide groove 404 and will not rotate downward. The cage cover 10 is rotated counterclockwise, and then the cage cover 10 will drive the rotating cage 405 to rotate counterclockwise. At this time, the rotating cage 405 can drive the arc-shaped baffle 403 to rotate inside the arc-shaped slide groove 404 through the friction with the associated block 501, so that the two arc-shaped baffles 403 can close the two slots 402 at the same time.

[0028] like Figure 2 and Figure 3 As shown, glass observation ports 12 are provided at positions of the shell 401 corresponding to the two slots 402. The glass observation ports 12 are arranged on a side close to the cage cover 10. The glass observation ports 12 allow the staff to see the position of the arc baffle 403 from the outside of the tank body 1, thereby ensuring that the arc baffle 403 is at the position of the slot 402 when adding microorganisms or cleaning the packing layer 406.

[0029] The working process is as follows:

[0030] S1, such as Figure 1 As shown, when in use, sewage is injected through the opening above the aeration area 2, and then the cooperation between the submersible pump 6, the pipeline 601 and the shock wave mass transfer device 602 is utilized to continuously cycle the water in and out and intermittently aerate. By adjusting the exposure or stop ratio, a multi-stage aerobic, anoxic or anaerobic state is created in the reaction tank, so that it is in the best denitrification and phosphorus removal condition;

[0031] S2, such as Figure 1 As shown, after the sewage is treated by aeration, it will flow into the separation area 3, and then the sludge and sewage will be screened by the three-phase separator 8, so that the sewage will enter the upper part of the separation area 3;

[0032] S3, such as Figure 1 , Figure 2 and Figure 4 As shown, when the sewage enters the inside of the rotating cage 405 through the notch 402 of the shell 401, the sewage will contact the Klebsiella inside the filler layer 406, thereby removing nitrogen and phosphorus in the sewage to the maximum extent, and the treated sewage will be discharged through the opening above the separation area 3;

[0033] S4, such as Figure 1 , Figure 2 and Figure 4 As shown, after the filler assembly 4 has been used for a period of time, the cage cover 10 is rotated by the handle 11, and then the cage cover 10 drives the rotating cage 405 to rotate, thereby adjusting the direction of the rotating cage 405, so that the Klebsiella inside the filler layer 406 can be fully utilized (after the filler layer 406 at the bottom is used for a long time, the Klebsiella below will gradually disappear, and the Klebsiella above will be less affected by the water flow, so the Klebsiella can be fully utilized after adjusting the direction) (as shown in FIG. Figure 2 and Figure 4 As shown, the handle 11 rotates the cage cover 10 clockwise, and at this time the arc-shaped baffle 403 is controlled by the arc-shaped slide groove 404 and does not rotate downward);

[0034] S5, such as Figures 2 to 7 As shown, when it is necessary to add microorganisms or clean the filler layer 406, the cage cover 10 is rotated counterclockwise, and then the cage cover 10 drives the rotating cage 405 to rotate counterclockwise. At this time, the rotating cage 405 can drive the arc baffle 403 to rotate inside the arc chute 404 through friction with the associated block 501, so that the two arc baffles 403 simultaneously close the two slots 402 (as shown in FIG. Figure 5 As shown, it is a schematic diagram of the state in which the arc-shaped baffle 403 closes the slot 402), at this time, the cage cover 10 can be opened to add microorganisms or clean the filler layer 406. At the same time, when adding microorganisms or cleaning the filler layer 406, sewage treatment can still be carried out.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
