Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to an efficient kitchen and bathroom sewage treatment system and method. Background Art

[0002] Kitchen and bathroom sewage is domestic sewage generated in the kitchen and bathroom. The sewage generated in the kitchen mainly contains food, grease and mud, while the sewage generated in the bathroom mainly contains feces and toilet paper.

[0003] In the existing kitchen and bathroom sewage treatment, most of the sewage from the kitchen and bathroom is first collected together, and then solid-liquid separation is performed through a screen or sedimentation tank to remove most of the suspended solids and organic matter in the sewage. The sewage is then biochemically treated to convert organic matter into inorganic matter through microorganisms. At the same time, the sewage is disinfected to significantly improve the water quality. The sewage is then further filtered and disinfected, and can be adsorbed by activated carbon, ultrafiltration, nanofiltration, etc., and finally discharged into the environment or reused.

[0004] According to the above-mentioned related technologies, kitchen sewage and bathroom sewage are treated uniformly, but kitchen sewage often contains a lot of grease, and the grease treatment efficiency in the kitchen and bathroom sewage treatment system needs to be improved. Summary of the Invention

[0005] In order to improve the grease treatment efficiency in kitchen and bathroom sewage treatment systems, the present application provides an efficient kitchen and bathroom sewage treatment system and method.

[0006] In the first aspect, the present application provides an efficient kitchen and bathroom sewage treatment system, which adopts the following technical solutions:

[0007] An efficient kitchen and bathroom sewage treatment system includes a first filter box for receiving kitchen sewage and a second filter box for receiving toilet sewage, and also includes a first sedimentation box, a second sedimentation box and a centralized filter box, the first filter box is connected to the first sedimentation box, and the second filter box is connected to the second sedimentation box; the first sedimentation box is provided with a cooling device, the bottom of the first sedimentation box is provided with a first sewage discharge valve, the first sewage discharge valve is connected to the centralized filter box, an oil scraping assembly is installed in the first sedimentation box, the side wall of the second sedimentation box is provided with a second sewage discharge valve, the second sewage discharge valve is connected to the centralized filter box, and the centralized filter box is connected in sequence to a biological pool and a filtration and disinfection pool.

[0008] By adopting the above technical solution, the sewage from the kitchen and the bathroom are discharged into the first filter box and the second filter box respectively. The kitchen sewage is precipitated in the first sedimentation box and then enters the centralized filter box, and the bathroom sewage is precipitated in the second sedimentation box and then enters the centralized filter box. Therefore, the kitchen sewage and the bathroom sewage are treated separately in the early stage and then treated together in the later stage. After the kitchen sewage enters the first sedimentation box, the cooling equipment reduces the sewage temperature, and the grease in the sewage solidifies and floats on the water surface. When the first sedimentation box is drained, the sewage is discharged from the bottom of the first sedimentation box, and a large amount of solidified grease remains in the second sedimentation box. The grease is then scraped off from the first sedimentation box by the oil scraping component. The second filter box and the second sedimentation box can intercept a large amount of feces, and the fecal water and some floating toilet paper enter the centralized filter box for further filtration.

[0009] Therefore, when treating kitchen sewage in the kitchen and bathroom sewage treatment system, grease will be specially treated, which improves the grease treatment efficiency of the kitchen and bathroom sewage treatment system. The sewage in the kitchen and bathroom will then be uniformly sent to the centralized filter box for treatment, thereby accelerating the overall sewage treatment efficiency.

[0010] Optionally, a drain valve is provided at the bottom of the first filter box, a first filter screen and a second filter screen are installed in the first filter box, the first filter screen is located above the second filter screen, a gap is left between the outer peripheral side of the first filter screen and the inner wall of the first filter box, and a sealing floating ring is installed in the first filter box, and the sealing floating ring slides up and down between the first filter screen and the second filter screen.

[0011] By adopting the above technical solution, the first filter allows sewage to pass directly through, and the first filter allows most of the residue to enter the second filter only through the gap between the first filter and the first filter box. When the sewage is higher than the first filter, the sealing floating ring can prevent the residue in the second filter from returning to the top of the first filter, so a large amount of floating residue will mainly be concentrated on the second filter.

[0012] Optionally, a residue processing assembly is also installed in the first filter box, and the residue processing assembly includes a push plate and a driving member that drives the push plate to slide back and forth on the second filter net. A residue collection box is installed at the bottom of the first filter box, and the opening of the residue collection box faces upward. A sealing plate for closing the residue collection box is rotatably installed on the side wall of the first filter box. When the push plate pushes the sealing plate to rotate, the residue collection box is connected to the first filter box.

[0013] By adopting the above technical solution, the residue on the second filter screen can be recovered by the residue collection box. When the first filter box filters the residue, the residue collection box is not connected to the first filter box, and the residue in the residue collection box can be cleaned.

[0014] Optionally, the first filter box is equipped with a stirring rod, and the portion of the stirring rod having the fan blades is located between the first filter screen and the second filter screen.

[0015] By adopting the above technical solution, when the sewage water level is higher than the first filter screen, in order to speed up the discharge of sewage in the first filter box, the stirring rod can be rotated to make the residue in the second filter screen float, so that the sewage can pass through the second filter screen smoothly, and the rotating fan blades carry the sewage to form a vortex, so that the sewage can better pass through the first filter screen, thereby speeding up the filtration speed in the first filter box.

[0016] Optionally, the oil scraping assembly includes a scraper and a power source for driving the scraper to move back and forth. An oil residue collection box is installed in the first sedimentation box. A water baffle is installed in the first sedimentation box for sealing and rotating to block the oil residue collection box. When the scraper pushes the water baffle to rotate, the oil residue collection box is connected to the first sedimentation box.

[0017] By adopting the above technical solution, the scraper can drop the grease into the oil residue collection box. When water is stored in the first sedimentation box and the water is cooled, the oil residue in the oil residue collection box can be cleaned.

[0018] Optionally, a third filter screen is installed in the second filter box, and the third filter screen is inclined downward toward the middle position of the second filter box. The second filter box is connected to a drain pipe, one end of the drain pipe passes through the middle position of the third filter screen, and one end of the drain pipe passes through the second filter box and is connected to the second sedimentation box. The bottom of the second filter box is connected to the centralized filter box.

[0019] By adopting the above technical solution, the third filter can filter part of the sewage and directly enter the centralized filter box, and the excrement and part of the sewage can also smoothly enter the sedimentation tank.

[0020] Optionally, a fourth filter screen is installed at the bottom of the centralized filter box, a rotating shaft is rotatably installed on the centralized filter box, a fan blade is installed on the rotating shaft, and a debris collection mechanism is installed in the centralized filter box.

[0021] By adopting the above technical solution, when the fan blades in the centralized filter box rotate, the residue in the centralized filter box can be lifted up, reducing the clogging of the fourth filter screen by the residue, and the sewage can pass through the centralized filter box smoothly.

[0022] Optionally, the debris collection mechanism includes a cleaning plate and a driving source that drives the cleaning plate to slide back and forth, the cleaning plate is provided with a makeshift groove for the rotating shaft and fan blades to pass through, the debris collection mechanism also includes a debris collection box and a sealing plate that blocks the debris collection box, the sealing plate is rotatably connected to a slider, the sealing plate and the slider slide in the centralized filter box, the sealing plate is provided with a through hole for the rotating shaft to pass through, and a push rod is installed on the cleaning plate to push the sealing plate. When the sealing plate rotates, the debris collection box is connected to the centralized filter box.

[0023] By adopting the above technical solution, when the sealing plate is plugged into the rotating shaft, the sealing plate cannot rotate. If the push rod does not push the sealing plate, the sealing plate and the slider are stably located in the centralized filter box, and the debris collection box is in a closed state; when the centralized filter box needs to be cleaned, the cleaning plate is pushed, and the cleaning plate scrapes off the debris in the centralized filter box. The cleaning plate pushes the sealing plate away from the rotating shaft first, and then drives the sealing plate and the slider to rotate, so that the debris collection box collects the debris.

[0024] Optionally, a return spring is connected to a side of the slider facing away from the rotating shaft.

[0025] By adopting the above technical solution, when the cleaning plate leaves the sealing plate and returns to its initial state, the reset spring can drive the slider and the sealing plate to slide toward the cleaning plate, and the sealing plate re-forms a plug-in relationship with the rotating shaft.

[0026] In a second aspect, the present application provides an efficient method for treating kitchen and bathroom sewage, which adopts the following technical solutions:

[0027] A highly efficient kitchen and bathroom sewage treatment method adopts the above-mentioned highly efficient kitchen and bathroom sewage treatment system for treatment, wherein kitchen sewage passes through a first filter box and a first sedimentation box in sequence, and bathroom sewage passes through a second filter box and a second sedimentation box in sequence; a cooling device in the first sedimentation box cools the kitchen sewage to solidify the grease in the sewage into blocks, and then the sewage in the first sedimentation box is discharged, and the grease in the first sedimentation box is scraped out and collected by an oil scraping component; the sewage flowing out of the first sedimentation box and the second sedimentation box is then uniformly sent to a centralized filter box for further filtration; the sewage flowing out of the centralized filter box enters a biological pool for decomposition, and finally enters a filtration and disinfection pool for disinfection.

[0028] By adopting the above technical solution, the sewage in the kitchen and bathroom is treated separately first, and the grease in the kitchen sewage can be preliminarily collected. After the grease is treated in the first sedimentation tank, the treatment efficiency of the sewage when it enters the biological pool and the filtration and disinfection pool will also be accelerated.

[0041] The following is combined with Figure 1-8 This application is described in further detail.

[0042] The embodiment of the present application discloses an efficient kitchen and bathroom sewage treatment system. Figure 1 An efficient kitchen and bathroom wastewater treatment system includes a first filter tank 1 for receiving kitchen wastewater, a second filter tank 2 for receiving bathroom wastewater, a first sedimentation tank 3 connected to the first filter tank 1, a second sedimentation tank 4 connected to the second filter tank 2, and a centralized filter tank 5. Both the second sedimentation tank 4 and the first sedimentation tank 3 are connected to the centralized filter tank 5. Kitchen wastewater passes through the first filter tank 1 and the first sedimentation tank 3 in sequence before entering the centralized filter tank 5. Bathroom wastewater passes through the second filter tank 2 and the second sedimentation tank 4 in sequence before entering the centralized filter tank 5. The centralized filter tank 5 filters both kitchen and bathroom wastewater again. The centralized filter tank 5 is connected to a biological tank 6 and a filtration and disinfection tank 7. Sewage flows from the centralized filter tank 5 into the biological tank 6, where microorganisms convert organic matter into inorganic matter. Finally, the water is filtered and disinfected, and may be adsorbed with activated carbon. Finally, it is discharged into the environment or reused.

[0043] The first filter box 1 can intercept a large amount of residue from kitchen wastewater, but grease dissolved in the water will still flow into the first settling tank 3 along with the water. The first settling tank 3 is equipped with a cooling device. The cooling device operates on the same principle as air conditioners and cold storage, and will not be further described in this embodiment. After the wastewater enters the first settling tank 3, it remains there for a period of time. After the cooling device cools the water to a low temperature, the grease in the wastewater solidifies and floats on the surface. A first wastewater discharge valve 31 is installed at the bottom of the first settling tank 3. This first wastewater discharge valve 31 is an electronic valve. A temperature sensor is installed in the first settling tank 3 and is connected to the first wastewater discharge valve 31. When the temperature sensor detects a specific temperature, the first wastewater discharge valve 31 opens to drain the wastewater. A net is installed at the valve port of the first wastewater discharge valve 12 to intercept lumps of grease. After the wastewater flows out, the solidified grease remains in the first settling tank 3, where an oil scraper assembly 8 is installed.

[0044] Reference Figure 2 and Figure 3The oil scraping assembly 8 includes a scraper 81 and a driving source that drives the scraper 81 to move back and forth. The outer peripheral side of the scraper 81 is attached to the bottom wall and side wall of the first sedimentation box 3. An oil residue collection box 82 is installed at the bottom of the first sedimentation box 3, and the opening of the oil residue collection box 82 faces upward. A water baffle 83 is rotatably installed in the first sedimentation box 3 to close the oil residue collection box 82. A torsion spring is installed in the first sedimentation box 3 to drive the water baffle 83 to maintain a vertical state. When the water baffle 83 remains in a vertical state, the oil residue collection box 82 is closed. One end of the torsion spring is fixedly connected to the top wall of the first sedimentation box 3, and the other end of the torsion spring is fixedly connected to the water baffle 83. The driving source is an electric telescopic rod. During implementation, whether to use a multi-section electric telescopic rod can be considered based on the overall size of the second sedimentation box 4. The telescopic rod of the electric telescopic rod extends into the first sedimentation box 3 and is fixedly connected to the scraper 81. The telescopic rod is sealed and slidably connected to the first sedimentation box 3.

[0045] The side of the water baffle 83 facing away from the scraper 81 may be equipped with a heating wire. When the electric telescopic rod is turned on, the heating wire also begins to heat up. As the electric telescopic rod moves with the scraper 81, the scraper 81 scrapes the grease from the bottom of the second sedimentation tank 4. The upper end of the scraper 81 may be equipped with a bump. When the scraper 81 approaches the water baffle 83, the bump pushes the water baffle 83, and the water baffle 83 rotates upward to open the oil residue collection box 82. The scraper 81 is positioned above the oil residue collection box 82. The heating wire on the water baffle 83 heats the grease on the scraper 81, causing it to melt and flow into the oil residue collection box 82. When the scraper 81 moves away from the water baffle 83, the torsion spring drives the water baffle 83 to seal the oil residue collection box 82. When the electric telescopic rod is closed, the heating wire also stops heating. The cooperation between the first sedimentation tank 3 and the grease collection box can collect most of the grease in the water, thereby improving the efficiency of the kitchen and bathroom sewage system in treating grease. When the sewage is subsequently treated uniformly, the grease content of the sewage is reduced, which can also improve the effect of the entire sewage treatment.

[0046] Reference Figure 4 Furthermore, a drain outlet 11 and a drain valve 12 for opening and closing the drain outlet 11 are provided at the bottom of the first filter box 1. When the scraping assembly 8 is scraping oil, the drain valve 12 is closed and the sewage is temporarily stored in the first filter box 1. A sewage inlet is provided at the top of the first filter box 1. There are at least two sewage inlets and they are not located in the middle of the first filter box 1. A first filter screen 13 and a second filter screen 14 are installed in the first filter box 1, and the first filter screen 13 is located above the second filter screen 14. The middle part of the first filter screen 13 is tilted downward and has a hollow conical structure. There is a gap between the outer peripheral side of the first filter screen 13 and the inner wall of the first filter box 1. A connecting rod 15 is connected between the first filter screen 13 and the inner top wall of the first filter box 1. Residue can fall onto the second filter screen 14 through the gap between the first filter screen 13 and the first filter box 1.

[0047] Reference Figure 4A sealing float ring 16 is installed in the first filter box 1. The sealing float ring 16 is located between the first filter screen 13 and the second filter screen 14 and slides on the inner wall of the first filter box 1. The inner wall of the sealing float ring 16 is inclined downward. As a result, if the sewage level in the first filter box 1 reaches the first filter screen 13, the sealing float ring 16 floats up to the first filter screen 13, thereby sealing the gap between the first filter screen 13 and the first filter box 1, and the residue in the second filter screen 14 will no longer enter the first filter screen 13.

[0048] Reference Figure 4 A residue handling assembly 9 is installed in the first filter box 1. The residue handling assembly 9 includes a push plate 91 and a driving member that drives the push plate 91 to slide back and forth on the second filter screen 14. The driving member is also an electric telescopic rod. The telescopic rod of the electric telescopic rod extends into the first filter box 1 and is fixedly connected to the push plate 91. The telescopic rod is sealed and connected to the first filter box 1. A residue collection box 92 is installed at the bottom of the first filter box 1. The opening of the residue collection box 92 faces upward. A sealing plate 93 for closing the residue collection box 92 is installed on the side wall of the first filter box 1 for sealing and rotating. A torsion spring is installed between the sealing plate 93 and the first filter box 1 so that the sealing plate 93 is normally in a vertical state. When the push plate 91 pushes the sealing plate 93 to rotate, the first filter box 1 is connected to the residue collection box 92.

[0049] Reference Figure 4 Furthermore, the first filter box 1 is equipped with a stirring rod 17, one end of which extends out of the first filter box 1 and is connected to a motor. The stirring rod 17 passes through the first filter screen 13, and the portion of the stirring rod 17 with the fan blades 54 is located between the first filter screen 13 and the second filter screen 14. When the sewage in the first filter box 1 overflows the first filter screen 13, the blocking floating ring 16 rises to block the gap between the first filter screen 13 and the first filter box 1, and the motor drives the stirring rod 17 to rotate, stirring the sewage, so that residue will not accumulate on the second filter screen 14, and the sewage can pass through the first filter screen 13 better, thereby accelerating the outflow of sewage from the first filter box 1.

[0050] Reference Figure 5Furthermore, the top of the second filter box 2 has a sewage inlet, and the sewage inlet is not located in the middle of the second filter box 2. A third filter screen 21 is installed in the second filter box 2. The third filter screen 21 is in the shape of an inverted cone. A sewage pipe 22 is connected to the middle position of the third filter screen 21. One end of the sewage pipe 22 extends out of the second filter box 2 and is connected to the second sedimentation box 4. When sewage enters the second filter box 2, excrement flows downward along the third filter screen 21 into the sewage pipe 22. The bottom of the second filter box 2 is connected to an outlet pipe 23, and the outlet pipe 23 is connected to the centralized filter box 5. When the sewage in the bathroom enters the second filter box 2, the sewage carries excrement and toilet paper from the sewage pipe into the second sedimentation box 4, and some sewage passes through the third filter screen 21 into the drain pipe.

[0051] Sewage, carrying feces and toilet paper, enters the second settling tank 4, where the feces primarily settle at the bottom. A second sewage discharge valve 41 is installed on the sidewall of the second settling tank 4, connecting the valve to the centralized filter tank 5 via a pipe. Sewage in the second settling tank 4 that overflows the valve 41 enters the centralized filter tank 5. Because some fingers, like wet toilet paper, partially dissolve in the sewage, they float, carrying the flocculent toilet paper with them. The sewage then enters the centralized filter tank 5 for filtration.

[0052] Reference Figure 5 and Figure 6 Furthermore, the centralized filter box 5 has an overall rectangular structure, and a fourth filter screen 51 is installed at the bottom of the centralized filter box 5. A guide plate 52 is also installed at the bottom of the centralized filter box 5 to facilitate the sewage to flow into the next sewage treatment process along the guide plate 52. A rotating shaft 53 is rotatably installed at one end of the centralized filter box 5. The length direction of the rotating shaft 53 is the same as the length direction of the centralized filter box 5, and the center line of the rotating shaft 53 is not located in the middle position of the centralized filter box 5. Fan blades 54 are installed on the rotating shaft 53. When the fan blades 54 rotate with the rotating shaft 53, the fan blades 54 contact the fourth filter screen 51 when they are close to the fourth filter screen 51. The fan blades 54 can scrape off some of the debris adhering to the fourth filter screen 51, so that the sewage can smoothly leave the centralized filter box 5, but the fan blades 54 mainly stir the left and right, so that the debris is not easy to accumulate on the fourth filter screen 51.

[0053] Reference Figure 5 and Figure 6Furthermore, a debris collection mechanism 10 is installed in the centralized filter box 5. The debris collection mechanism 10 includes a cleaning plate 101 and a driving source that drives the cleaning plate 101 to slide back and forth. The cleaning plate 101 is provided with a clearance groove for the rotation shaft 53 and the fan blades 54 to pass through. When the rotation shaft 53 stops rotating, the fan blades 54 move away from the fourth filter screen 51. The driving source can be an electric telescopic rod, one end of the telescopic rod of the electric telescopic rod extends into the centralized filter box 5 and is sealed with the centralized filter box 5, and one end of the telescopic rod is fixedly connected to the cleaning plate 101. When the electric telescopic rod drives the cleaning plate 101 to slide, the outer peripheral side of the cleaning plate 101 slides in contact with the inner wall of the centralized filter box 5 and the fourth filter screen 51. The cleaning plate 101 can scrape the debris adhering to the centralized sealed box along one end of the centralized sealed box to the other end.

[0054] Reference Figure 5 and Figure 7 Furthermore, the debris collection mechanism 10 also includes a debris collection box 102 and a sealing plate 103 for sealing the debris collection box 102. The sealing plate 103 is rotatably connected to a slider 104. The slider 104 slides the sealing plate 103 with the sealing plate 103 within the centralized filter box 5, allowing the sealing plate 103 to rotate relative to the slider 104. The sealing plate 103 has a through hole for the rotating shaft 53 to pass through. When the sealing plate 103 is connected to the rotating shaft 53, the sealing plate 103 can only slide within the centralized filter box 5, and the debris collection box 102 is in a closed state. A push rod 1011 is mounted on the cleaning plate 101 to push the sealing plate 103. The sealing plate 103 pushes the sealing plate 103 with the push rod 1011. The sealing plate 103 first slides away from the rotating shaft 53. When the push rod 1011 pushes the sealing plate 103 again, the sealing plate 103 rotates away from the bottom of the centralized filter box 5. The debris collection box 102 is connected to the centralized filter box 5. The push plate 91 scrapes the debris in the centralized filter box 5 and pushes it into the debris collection box 102.

[0055] Sealing plate 103 and slider 104 are also connected by a torsion spring, which drives sealing plate 103 to a vertical position to seal centralized filter box 5, preventing sewage in centralized filter box 5 from entering debris collection box 102. Slider 104 and sealing plate 103 are both mounted on sealing strips (not shown in the figure), which contact centralized filter box 5 and enhance the sealing between sealing plate 103 and centralized filter box 5.

[0056] Reference Figure 8 When the push rod 1011 of the cleaning plate 101 leaves the sealing plate 103, a return spring 105 is connected between the side of the slider 104 facing away from the rotating shaft 53 and the centralized filter box 5 to reconnect the sealing plate 103 with the rotating shaft 53. Multiple return springs 105 are installed. The elastic force of the return spring 105 drives the slider 104 to slide, reconnecting the sealing plate 103 with the rotating shaft 53.

[0057] It should be noted that the mesh size of the first filter 13 is larger than that of the second filter 14, the mesh size of the third filter 21 can be equal to that of the second filter 14, and the mesh size of the fourth filter 51 is the smallest. The grease collection box, the residue collection box 92, and the debris collection box 102 all have a cleaning port and a sealing door for blocking the cleaning port.

[0058] The implementation principle of an efficient kitchen and bathroom sewage treatment system in the embodiment of the present application is as follows:

[0059] The sewage from the kitchen and bathroom is discharged into the first filter box 1 and the second filter box 2 respectively. Most of the residues in the kitchen sewage are filtered out when passing through the first filter box 1. The first sedimentation box 3 can remove grease from the sewage. When the sewage in the bathroom passes through the first filter box 1, part of the sewage passes through the third filter net 21 and directly enters the centralized filter box 5. Most of the sewage, excrement and toilet paper enter the second sedimentation tank through the sewage pipe 22. The excrement is mainly precipitated in the second sedimentation tank. The sewage and toilet paper floating in the sewage enter the centralized filter box 5. The centralized filter box 5 uniformly treats the sewage from the kitchen and bathroom. Some of the grease in the kitchen sewage has been processed. Therefore, the efficiency of the kitchen and bathroom sewage treatment system in treating sewage can be improved.

[0060] The embodiments of the present application also disclose an efficient method for treating kitchen and bathroom sewage.

[0061] A highly efficient kitchen and bathroom sewage treatment method employs the aforementioned efficient kitchen and bathroom sewage treatment system. Kitchen sewage sequentially passes through a first filter tank 1 and a first sedimentation tank 3, while bathroom sewage sequentially passes through a second filter tank 2 and a second sedimentation tank 4. A cooling device within the first sedimentation tank 3 cools the kitchen sewage, causing the grease in the sewage to solidify into lumps. The sewage in the first sedimentation tank 3 is then discharged, and the grease in the first sedimentation tank 3 is scraped and collected by an oil scraping assembly 8. The sewage flowing out of the first and second sedimentation tanks 3, 4, is then collectively filtered in a centralized filter tank 5. The sewage from the centralized filter tank 5 then enters a biological tank 6 for decomposition, and finally enters a filtration and disinfection tank 7 for disinfection. After passing through the kitchen and bathroom sewage treatment system, the sewage is discharged or reused.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
