Description

Septic Tank Gas Control System

[0001] Embodiments disclosed in this document relate to a purification tank gas control system.

[0002] Sewage, as defined by the Sewerage Act, refers to wastewater generated or incidental to daily life or business operations. It encompasses wastewater containing human excrement, such as flush toilet drainage, drainage from bathrooms and sinks, or other wastewater significantly contaminated with such substances. However, within buildings, only wastewater containing excrement is considered sewage for sanitary reasons, while drainage from bathrooms and sinks is classified as miscellaneous wastewater. Sewage generally contains a high amount of organic matter, resulting in a high biochemical oxygen demand (BOD). Discharging wastewater into rivers consumes dissolved oxygen, endangering the survival of fish and other organisms. Therefore, prior treatment may be essential before discharge.

[0003] Septic tanks are installed in each building as pretreatment facilities for wastewater. These tanks allow wastewater to settle and undergo anaerobic digestion at the bottom, while only effluent is discharged. While the sedimentation and anaerobic processes reduce solids and organic matter, treatment efficiency remains mediocre. Therefore, septic tank systems are essentially a simple on-site sewage system.

[0004] As illustrated in Fig. 1, a septic tank can send wastewater discharged from a living facility to a sewage treatment facility through a sewer after first purifying it through a septic tank (110), a filtration tank (120), an oxidation tank (130), and a disinfection tank (140). During this process, various gases may be emitted from the inside of the septic tank. These emitted gases may not only generate a complex foul odor, but in particular, some toxic gases such as methane (CH4), hydrogen sulfide (H2S), and ammonia (NH3) may cause an explosion inside the septic tank, resulting in not only casualties but also property damage, including the septic tank facility.

[0005] Traditionally, odor reduction facilities (e.g., air supply devices) have been installed to remove foul odors generated from septic tanks. However, these only provide a certain degree of odor reduction and may be insufficient to control various toxic gases generated from thickly accumulated sludge-like waste (e.g., excrement, etc.) in septic tanks (110).

[0006] In various embodiments disclosed in this document, a septic tank gas control system can be provided that removes toxic gases (e.g., methane (CH4), hydrogen sulfide (H2S), and ammonia (NH3)) generated within a septic tank.

[0007] According to one embodiment, a septic tank gas control system includes: detection sensors disposed at designated locations within a septic tank interior space, each of which detects a detection signal for methane (CH4), hydrogen sulfide (H2S), and ammonia (NH3); and a spray device that sprays a spray liquid into the septic tank interior space in response to receiving the detection signals from the detection sensors, wherein the spray device includes a communication module that receives the detection signals from the detection sensors; and a processor operatively connected to the communication module, wherein the processor determines a ratio for mixing water and lactic acid bacteria disposed in a first tray of the spray device when receiving the detection signals through the communication module, and when the water and the lactic acid bacteria are mixed in the form of the spray liquid on a second tray of the spray device according to the ratio, the processor can control the spray liquid to be sprayed from a spray port connected to the second tray based on a position of a detection sensor among the detection sensors that detected the detection signal.

[0008] According to one embodiment, the injection device is connected through a pipeline from the injection port to a point corresponding to the position of each of the detection sensors, and valves are installed on the pipeline at each point corresponding to the position of each of the detection sensors, and the processor determines an opening or closing operation of each of the valves based on a position of a detection sensor among the detection sensors that has detected the detection signal, and controls the injection liquid to be sprayed toward a point on the pipeline corresponding to a position of a detection sensor among the detection sensors that has detected the detection signal.

[0009] According to one embodiment, the first tray is installed so as to be withdrawable in a sliding shelf manner from the main body of the injection device, and a first pipe formed at a lower end of the first tray and a second pipe formed at an upper end of the second tray are arranged between the first tray and the second tray, and the water and the lactic acid bacteria can be moved from the first tray to the second tray through the first pipe and the second pipe.

[0010] In one embodiment, the radius of the first pipe may be a first length, and the radius of the second pipe may be a second length that is longer than the first length.

[0011] In one embodiment, the second tray can move the spray liquid from the second tray to the nozzle based on the movement of the vibrator.

[0012] According to one embodiment, the injection device further includes a display exposed to the outside of the injection device, and the processor can control the determination of the toxic gas concentration for each zone of the internal space of the purification tank based on the detection signal received through the communication module, and to display the determined toxic gas concentration for each zone through the display.

[0013] According to one embodiment, the purification tank gas control system further includes a user terminal communicatively connected via a network, and the processor may be configured to transmit information related to the determined toxic gas concentration by zone to the user terminal.

[0014] The septic tank gas control system according to various embodiments disclosed in this document can reduce foul odors in the septic tank by removing toxic gases (e.g., methane (CH4), hydrogen sulfide (H2S), and ammonia (NH3), etc.) generated within the septic tank, and can also prevent explosion accidents caused by a large amount of toxic gases generated from thickly accumulated sludge-like waste.

[0027] Therefore, it should be understood that the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, and that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0028] Figure 2 is a block diagram of a purification tank gas control system according to one embodiment.

[0029] According to one embodiment, the purification tank gas control system (200) may include a spray device (210), a user terminal (220), and an integrated control server (230). In one embodiment, the spray device (210), the user terminal (220), and the integrated control server (230) may be communicatively connected via a network (201) (e.g., a long-distance communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network).

[0030] According to one embodiment, the injection device (210) may include a communication module (211), a processor (212), an injection port (213), and a display (215). The injection device (210) may inject a spray liquid (214) into the internal space of the septic tank in response to receiving a detection signal from a plurality of detection sensors (S) installed in the internal space of the septic tank. The detection sensors (S) may be arranged at a specified interval (e.g., a checkerboard arrangement) on the ceiling of the internal space of the septic tank, for example. The detection sensors (S) may detect detection signals for methane (CH4), hydrogen sulfide (H2S), and ammonia (NH3), respectively.

[0031] According to one embodiment, the communication module (211) can receive detection signals for methane (CH4), hydrogen sulfide (H2S), and ammonia (NH3) from each of the detection sensors (S). In one embodiment, the communication module (211) can support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the injection device (210) and an external electronic device (e.g., a user terminal (220) and an integrated control server (230)), and the performance of communication through the established communication channel. The communication module (211) can include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, a corresponding communication module can communicate with the user terminal (220) and the integrated control server (230) through the network (201).

[0032] According to one embodiment, when the processor (212) receives a detection signal through the communication module (211), it can determine a mixing ratio for mixing water and lactic acid bacteria placed in the first tray (e.g., the first tray (T1) of FIG. 3A) of the injection device (210).

[0033] According to one embodiment, the processor (212) may cause water and lactic acid bacteria to be mixed in the form of a spray liquid on the second tray (e.g., the second tray (T2) of FIG. 3A) of the spray device (210) according to the determined mixing ratio. The processor (212) may control the spray liquid to be sprayed from the spray port (213) connected to the second tray (T2) based on the position of the detection sensor (S) that detected the detection signal among the detection sensors (S). Alternatively, when a plurality of detection signals are received from each of the detection sensors (S), the processor (212) may control the spray liquid to be sprayed toward a position corresponding to the detection sensor (S) that transmitted the detection signal having the highest toxic gas concentration among the received detection signals within the space inside the septic tank, based on the detection signal having the highest toxic gas concentration among the received detection signals. In this case, the processor (212) can control the opening or closing operation of the valves (V) connected through the nozzle (213) and the pipeline (e.g., the pipeline (P) of FIG. 4a).

[0034] According to one embodiment, the processor (212) may receive commands or instructions from a user terminal (220) and an integrated control server (230), and control each component according to the received commands or instructions to perform various functions. In various embodiments, the control unit may be implemented as a central processing unit (CPU), a micro control unit (MCU), or a micro processor unit (MPU).

[0035] In one embodiment, the display (215) may be exposed to the outside of the spray device (210). The display (215) may visually provide information to the outside. For example, the display (215) may display an image indicating the concentration of toxic gases by zone on a map representing the internal space of the septic tank. The display (215) may also include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the strength of a force generated by the touch.

[0036] FIG. 3 is a drawing showing the durability structure of an injection device according to one embodiment. FIG. 4 is an enlarged drawing showing a piping connection part of an injection device according to one embodiment. FIG. 5 is a drawing showing a front view of an injection device according to one embodiment.

[0037] According to one embodiment, the spray device (310) may include a first tray (T1) for storing containers containing raw materials (314a, 314b) of the spray liquid and a fragrance (314c), respectively, and a second tray (T2) for storing baskets (B1, B2) for receiving raw materials of the spray liquid and a fragrance, respectively, from the first tray (T1).

[0038] According to one embodiment, the first raw material (314a) of the spray liquid, water, and the second raw material (314b) of the lactic acid bacteria may be moved to baskets (B1, B2) located in the second tray (T2) through pipes and then mixed. For example, the lactic acid bacteria may be moved to the first basket (B1) through the first pipe (314b') formed at the lower end of the first tray (T1) and the second pipe (B1') formed at the upper end of the second tray (T2). Here, the radius (r2) of the second pipe (B1') may be longer than the radius (r1) of the first pipe (314b'). Accordingly, even if the first tray (T1) is pulled out from the main body of the injection device (310) in a sliding shelf manner to refill the raw materials (314a, 314b) and then reintroduced into the main body, the lactic acid bacteria can be moved to the second pipe (B1') without leaking out from the first pipe (314').

[0039] According to one embodiment, when a spray liquid is prepared by mixing the first raw material (314a) and the second raw material (314b) in the first basket (B1), the prepared spray liquid can be sprayed into the internal space of the purification tank through the first spray port (313a). In addition, a certain amount of the air freshener (314) contained in the second basket (B2) can be sprayed into the internal space of the purification tank through the second spray port (313b).

[0040] According to the above-described injection operation, the real-time change in the toxic gas concentration for each area of ​​the internal space of the septic tank can be displayed in the form of a map of the internal space of the septic tank on the display (315) located in front of the injection device (310). For example, on a three-dimensional map corresponding to the internal space of the septic tank, the toxic gas concentration at point A can be displayed in red (e.g., high toxic gas concentration), and the toxic gas concentration at point B can be displayed in green (e.g., low toxic gas concentration).

[0041] Fig. 6 is a drawing illustrating the injection function of a purification tank gas control system according to one embodiment. Fig. 6 may be a drawing illustrating a top view of the inside of a purification tank. Fig. 7 is a drawing illustrating the injection function of a purification tank gas control system according to one embodiment. Fig. 7 may be a drawing illustrating a side view of the inside of a purification tank corresponding to Fig. 6.

[0042] According to one embodiment, the injection device (610) may be connected via a pipeline (P) from the injection port (213) to a point corresponding to the position of each of the detection sensors (S). Here, valves (V) that can be set to an open or closed state may be installed on the pipeline (P) at each point corresponding to the position of each of the detection sensors (S).

[0043] According to one embodiment, the injection device (610) can determine the opening or closing operation of each valve (V) based on the position of the detection sensor that detected the detection signal among the detection sensors (S). For example, if the injection device (610) determines that a toxic gas detection signal (G) is detected at a certain point through the detection sensor (S), the injection device (610) can set only the valve (V) closest to the position of the detection sensor that detected the toxic gas detection signal (G) on the pipeline (P) to an open state, and set the remaining valves (V) to a closed state. Accordingly, the injection liquid including the lactic acid bacteria (L) can be injected toward a point corresponding to the position of the detection sensor (S) that detected the toxic gas detection signal (G) among the detection sensors (S).

[0044] FIG. 8 is a drawing showing a state in which bacteria in a toxic gas are removed by a spray liquid sprayed from a spray device according to one embodiment.

[0045] Referring to the first state (800a), immediately after the spray liquid containing lactobacillus lactic acid bacteria is immersed in a toxic gas (e.g., methane (CH4), hydrogen sulfide (H2S), and ammonia (NH3)), the number of bacteria can be maintained for the most part.

[0046] Referring to the second state (800b), when the spray liquid containing lactobacillus lactic acid bacteria is immersed in a toxic gas (e.g., methane (CH4), hydrogen sulfide (H2S), and ammonia (NH3)) and a certain period of time (e.g., 96 hours) elapses, it can be confirmed that the number of bacteria is noticeably reduced.

[0047] FIG. 9 is a diagram showing the change in gas volume in each of an aeration tank and an anaerobic tank due to the sprayed liquid sprayed from a spray device according to one embodiment.

[0048] Referring to the first graph (900a), it can be confirmed that the internal gas change amount of the aeration tank where the sludge-like organic matter mass and oxygen meet in the purification tank rapidly decreases after spraying the spray solution including the Lactobacillus lactic acid bacteria according to the embodiments of the present invention described above.

[0049] Referring to the second graph (900b), it can be confirmed that the internal gas change amount of an anaerobic tank, which is a tank that reduces the concentration of pollutants by bringing anaerobic bacteria and sewage into contact with each other in a septic tank, decreases rapidly after spraying the spray solution containing the Lactobacillus lactic acid bacteria according to the embodiments of the present invention described above, similar to the internal gas change amount of the aeration tank.

[0050] As described above, although the present invention has been described by limited embodiments and drawings, the present invention is not limited thereto, and various modifications and variations are possible by a person having ordinary skill in the art to which the present invention pertains within the scope of the technical idea of ​​the present invention and the equivalent scope of the claims to be described below.
