Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an integrated filter device for intercepting pests and performing microbial decomposition in drainage pipes of buildings. Background Art

[0002] Buildings discharge a significant amount of wastewater daily, a quantity closely related to living and production levels. Wastewater contains a large amount of organic matter, such as cellulose, starch, sugars, fats, and proteins; it also often contains pathogens, viruses, and parasite eggs; and inorganic salts such as chlorides, sulfates, phosphates, bicarbonates, and sodium, potassium, calcium, and magnesium.

[0003] Rural domestic sewage, derived from facilities like toilets, kitchens, and showers, contains sediment, grease, soap, food scraps, debris, and pathogens. This water quality is reflected in high biochemical oxygen demand (BOD5), chemical oxygen demand (COD), and suspended solids (SS), as well as high nitrogen and phosphorus levels, leading to eutrophication. If discharged directly into water bodies (rivers, lakes, seas, and groundwater) and soil without treatment, it can lead to excessive concentrations of organic matter in these waters and soils, resulting in eutrophication. Organic matter in domestic sewage is extremely unstable and easily decomposes, producing foul odors. Bacteria and pathogens use organic matter in domestic sewage as nutrition and multiply rapidly, which can lead to the spread of infectious diseases.

[0004] When the filter screen inside the existing drainage pipe intercepts and accumulates a certain amount of solid impurities, the water flow through the filter screen will slow down and cause blockage in the pipe, resulting in the inability to discharge sewage in time or even sewage backflow. When this happens, manual inspection of the pipe section by section is required. The efficiency is very low because the blockage cannot be found immediately during the inspection process. In addition, during the process of clearing the blocked pipe, the drainage work will be stopped to ensure the smooth progress of the cleaning process. The cleaning process also forces the upstream work to stop, reducing the overall work efficiency. In addition, many pest larvae and eggs attach to solid debris, causing pest pollution. Therefore, it is necessary to provide an integrated filter device for intercepting pests and decomposing pests through microorganisms in drainage pipes of buildings. Summary of the Invention

[0005] In view of the defects in the prior art, the present invention provides an integrated filter device for intercepting pests and performing microbial decomposition in drainage pipes of buildings.

[0006] The technical solution adopted by the present invention is: an integrated filter device for pest interception and microbial decomposition in the drainage pipes of buildings, including a load-bearing pipe and a sewage pipe. The sewage pipe is arranged inside the load-bearing pipe, and a degradation cavity is formed between the sewage pipe and the load-bearing pipe, and a degradation mechanism is arranged in the degradation space; multiple filtering mechanisms are arranged in sequence along the sewage pipe.

[0007] In order to better implement the present invention, each of the filtering mechanisms includes four groups of fan-shaped filtering and intercepting nets.

[0008] In order to better realize the present invention, the four groups of fan-shaped filter interception nets include a fan-shaped filter screen, a frame is provided on the radius edge of the fan-shaped filter screen, and a sealing strip adapted to the sewage pipe is provided on the arc edge; the sealing strip is connected to a pull-out mechanism.

[0009] To better implement the present invention, the pulling mechanism includes a driving motor fixed on the load-bearing pipe, a threaded rod is connected to the rotating shaft of the driving motor, and a threaded hole matching the threaded rod is provided on the sealing strip.

[0010] To better implement the present invention, the degradation mechanism includes a load-bearing pad provided between the load-bearing pipe and the sewage pipe, and a plurality of filling holes are provided on the load-bearing pad, each of which is filled with fillers.

[0011] In order to better implement the present invention, the filler holes are arranged along the length direction of the sewage pipe.

[0012] In order to better implement the present invention, the filler hole is a polygonal structure.

[0013] In order to better implement the present invention, a cleaning hole is opened on the load-bearing pipe.

[0014] The beneficial effects of the present invention are embodied in: the present invention is an integrated filter device for intercepting pests and decomposing pests in the drainage pipes of buildings, through the cooperation of load-bearing pipes, sewage pipes, degradation cavities, degradation mechanisms and filtering mechanisms, etc. When the sewage of the building is discharged, the filtering mechanism on the sewage pipe can timely and effectively filter out harmful substances such as debris and insect eggs, and send these substances into the degradation cavity for degradation through the degradation mechanism, which can ensure smooth sewage discharge from the sewage pipe while greatly reducing pollution and pests.

[0015] Each of the filtering mechanisms includes four groups of fan-shaped filtering interception nets. When filtering, the four groups of fan-shaped filtering interception nets can be controlled separately to output the residue separately, while keeping the sewage pipe continuously and effectively discharging sewage.

[0016] The four sets of sector-shaped filter interception screens include a sector-shaped filter screen with a frame on its radial edge and a sealing strip on its curved edge that fits the sewage pipe. The sealing strip is connected to a pull-out mechanism. With this design, the sector-shaped filter screen filters the sewage pipe, and the pull-out mechanism pulls out the sector-shaped filter screen, directing debris, insect eggs, and the like into the degradation cavity, ensuring smooth drainage of the sewage pipe while effectively degrading and killing insects.

[0017] The pull-out mechanism includes a drive motor fixed to a load-bearing pipe. A threaded rod is connected to the drive motor's rotating shaft, and a threaded hole is provided on the sealing strip that mates with the threaded rod. During operation, the drive motor is activated to rotate its rotating shaft, driving the threaded rod. Because the threaded rod mates with the threaded hole, the rotation of the threaded rod drives the sealing strip to move radially relative to the threaded rod, thereby pulling out the sector-shaped filter screen and allowing debris, insect eggs, and the like on the screen to fall into the degradation cavity.

[0018] The degradation mechanism includes a load-bearing spacer positioned between the load-bearing pipe and the sewage pipe. The spacer is provided with multiple filling holes, each of which is filled with filler. This design allows debris, insect eggs, and the like on the fan-shaped filter to fall into the degradation cavity. The filler in the holes effectively degrades the debris, preventing insect eggs from hatching in the sewage pipe and reducing pest infestation.

[0019] The filler holes are arranged along the length direction of the sewage pipe, which can facilitate the sewage to flow further along the sewage pipe.

[0020] The filler hole is a polygonal structure. This design can increase the contact area between the filler and the slag, greatly improving the degradation efficiency.

[0021] A cleaning hole is provided on the load-bearing pipe. After being designed like this, the cleaning hole can be opened after using for a period of time to clean the slag in the degradation cavity and replenish the medicine for killing insects. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example: like Figures 1 to 4 As shown, the present invention is an integrated filter device for intercepting pests and decomposing microorganisms in a building drainage pipe, comprising a load-bearing pipe 1 and a sewage pipe 2. The sewage pipe 2 is sleeved in the load-bearing pipe 1, and a degradation cavity 3 is formed between the sewage pipe 2 and the load-bearing pipe 1, and a degradation mechanism is provided in the degradation space; a plurality of filtering mechanisms are sequentially provided along the sewage pipe. The present invention is an integrated filter device for intercepting pests and decomposing microorganisms in a building drainage pipe. Through the cooperation of the load-bearing pipe 1, the sewage pipe 2, the degradation cavity 3, the degradation mechanism and the filtering mechanism, when the building sewage is discharged, the filtering mechanism on the sewage pipe 2 can timely and effectively filter out harmful substances such as debris and insect eggs, and send these substances into the degradation cavity 3 for degradation by the degradation mechanism, which can ensure smooth sewage discharge from the sewage pipe while greatly reducing pollution and pests. It should be noted that an appropriate amount of insecticide can be pre-placed in the degradation cavity 3.

[0029] As a preferred embodiment, each of the filtering mechanisms includes four sets of sector-shaped filter interception nets. In this embodiment, each of the filtering mechanisms includes four sets of sector-shaped filter interception nets. During filtration, the four sets of sector-shaped filter interception nets can be controlled separately to output the residue separately while maintaining continuous and effective sewage discharge from the sewage pipe.

[0030] As a preferred embodiment, the four groups of fan-shaped filter interception nets include a fan-shaped filter 7, a frame is provided on the radius edge of the fan-shaped filter 7, and a sealing strip 6 adapted to the sewage pipe 2 is provided on the arc edge; the sealing strip 6 is connected to a pull-out mechanism. In this embodiment, the four groups of fan-shaped filter interception nets include a fan-shaped filter 7, a frame is provided on the radius edge of the fan-shaped filter 7, and a sealing strip 6 adapted to the sewage pipe 2 is provided on the arc edge; the sealing strip 6 is connected to a pull-out mechanism. After such a design, the fan-shaped filter 7 filters the sewage pipe 2, and the pull-out mechanism can pull out the fan-shaped filter 7, and guide the residue, insect eggs, etc. into the degradation cavity 3, ensuring that the sewage pipe 2 can discharge smoothly while effectively degrading and killing insects. It should be noted that when the pulling mechanism pulls out the fan-shaped filter 7, part of the sewage will be flushed into the degradation cavity 3. On the one hand, it can flush the residue and insect eggs on the fan-shaped filter 7 into the degradation cavity 3. On the other hand, it can also provide moisture to facilitate the full integration of fillers and insecticides.

[0031] As a preferred embodiment, the pulling-out mechanism includes a driving motor 4 fixed to the load-bearing pipe 1, a threaded rod 5 is connected to the rotating shaft of the driving motor 4, and a threaded hole 8 is provided on the sealing strip 6 to cooperate with the threaded rod 5. In this embodiment, the pulling-out mechanism includes a driving motor 4 fixed to the load-bearing pipe 1, a threaded rod 5 is connected to the rotating shaft of the driving motor 4, and a threaded hole 8 is provided on the sealing strip 6 to cooperate with the threaded rod 5. When in use, the driving motor 4 is controlled to start, and its rotating shaft is rotated, thereby driving the threaded rod 5 to rotate. Since the threaded rod 5 cooperates with the threaded hole 8, when the threaded rod 5 rotates, it can drive the sealing strip 6 to move relative to each other in the radial direction, thereby pulling out the fan-shaped filter screen 7, so that the residue, insect eggs, etc. on the fan-shaped filter screen 7 fall into the degradation cavity 3.

[0032] As a preferred embodiment, the degradation mechanism includes a load-bearing pad 9 provided between the load-bearing pipe 1 and the sewage pipe 2, and a plurality of filling holes 10 are provided on the load-bearing pad 9, each of which is filled with fillers. In this embodiment, the degradation mechanism includes a load-bearing pad 9 provided between the load-bearing pipe 1 and the sewage pipe 2, and a plurality of filling holes 10 are provided on the load-bearing pad 9, each of which is filled with fillers. With this design, when the debris, insect eggs, etc. on the fan-shaped filter screen fall into the degradation cavity 3, the fillers in the filling holes 10 can effectively degrade the debris, prevent insect eggs from hatching in the sewage pipe, and reduce insect pests.

[0033] As a preferred embodiment, the packing holes 10 are arranged along the length direction of the sewage pipe 2. In this embodiment, the packing holes 10 are arranged along the length direction of the sewage pipe 2, which can facilitate the sewage to flow further along the sewage pipe.

[0034] As a preferred embodiment, the filler hole 10 is a polygonal structure. In this embodiment, the filler hole 10 is a polygonal structure. This design can increase the contact area between the filler and the slag, greatly improving the degradation efficiency.

[0035] As a preferred embodiment, a cleaning hole is opened on the load-bearing pipe 1. In this embodiment, after a period of use, the cleaning hole can be opened to clean the residue in the degradation cavity 3 and replenish the insecticide.

[0036] It should be noted that multiple groups of membrane bioreactors (MBRs) can be set in the degradation cavity 3. The membrane bioreactor (MBR) is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. The membrane assembly replaces the secondary sedimentation tank to maintain a high activated sludge concentration in the bioreactor, reducing the footprint of the sewage treatment facility and reducing the amount of sludge by maintaining a low sludge load. Due to its effective interception effect, the membrane bioreactor can retain microorganisms with a long generation cycle, which can achieve deep purification of sewage. At the same time, nitrifying bacteria can fully reproduce in the system, and its nitrification effect is obvious, providing the possibility of deep phosphorus and nitrogen removal. Compared with traditional biochemical water treatment technology, this process not only effectively achieves the purpose of mud and water separation, but also has incomparable advantages over traditional tertiary sewage treatment processes: 1. It can efficiently separate solid and liquid, and its separation effect is much better than that of traditional sedimentation tanks. The effluent water quality is good, and the suspended solids and turbidity of the effluent are close to zero. It can be directly reused, realizing the resource utilization of sewage.

[0037] 2. The efficient interception effect of the membrane allows the microorganisms to be completely retained in the bioreactor, achieving complete separation of the reactor's hydraulic retention time (HRT) and sludge age (SRT), and flexible and stable operation control.

[0038] 3. Since MBR combines the aeration tank and secondary sedimentation tank of traditional sewage treatment into one and replaces all the process facilities of tertiary treatment, it can greatly reduce the occupied area and save civil engineering investment.

[0039] 4. It is conducive to the retention and reproduction of nitrifying bacteria, and the system has high nitrification efficiency. By changing the operating mode, it can also have deammoniation and phosphorus removal functions.

[0040] 5. Since the sludge age can be very long, the degradation efficiency of difficult-to-degrade organic matter can be greatly improved.

[0041] 6. The reactor operates under high volume load, low sludge load and long sludge age. The residual sludge production is extremely low. Since the sludge age can be infinitely long, zero sludge discharge can be achieved in theory.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
