[0001] This invention relates to the technical field of using microorganisms to degrade organic matter in brewing wastewater, and more specifically to an apparatus for using microorganisms to degrade organic matter in brewing wastewater. Background Technology

[0002] During the production process of a winery, a large amount of wastewater is generated. According to statistics, it takes about 24 tons of water and 20 tons of brewing wastewater to produce 1 ton of 53% vol baijiu. The brewing wastewater contains a large amount of organic matter, inorganic matter, microorganisms and nutrients. The main pollutant in the wastewater is organic matter. Direct discharge will cause serious eutrophication and other problems. The decomposition of organic matter requires a large number of anaerobic or aerobic microorganisms to absorb the organic matter and generate biogas.

[0003] Typical devices that utilize microorganisms to degrade organic matter in brewing wastewater treat the organic matter through activated sludge or biofilm processes. Some existing devices use stirring equipment to agitate the brewing wastewater, which can easily damage the activated sludge or biofilm. Summary of the Invention

A retaining ring with a diameter smaller than that of the forward sliding piston ring and the side sliding piston ring is provided on the side of the agitating piston ring away from the partition plate. The diameters of the forward sliding piston ring and the side sliding piston ring are the same as the inner diameter of the agitating piston ring.

[0009] Preferably, the agitating piston ring has circumferentially arrayed arc-shaped grooves inside, the arc-shaped grooves of the agitating piston ring connect the inside and outside of the agitating piston ring, and the length of the arc-shaped grooves of the agitating piston ring is less than half the length of the agitating piston ring and is located on the side of the agitating piston ring away from the partition plate.

[0010] Preferably, an inner partition ring is fixedly connected inside the biofilm reaction tube, and a sliding rod is slidably connected inside the inner partition ring. Both ends of the sliding rod are fixedly connected to piston cover plates. The diameter of the piston cover plates is smaller than the inner diameter of the biofilm reaction tube. Symmetrically distributed fan-shaped grooves are formed on the inner partition ring, and the diameter of the fan-shaped grooves on the inner partition ring is smaller than the diameter of the piston cover plates.

[0011] Preferably, a pressure-reducing tension spring is provided between the sliding piston gas cover and the top cover around a fixed axis. The pressure-reducing tension spring is fixedly connected to the top cover and the sliding piston gas cover. The tension of the pressure-reducing tension spring is less than the tension required for the biofilm reaction tube and the inner separator ring to move horizontally.

[0012] Preferably, a connecting frame is fixedly connected to the lower end of the transmission piston sleeve on one side, and a side traction rope is slidably connected through the connecting frame. A side limiting baffle is fixedly connected to the end of the side traction rope away from the partition plate, and the other end of the side traction rope is fixedly connected to the piston cover plate. A side limiting rope frame is fixedly connected inside the positive reaction tube, and the side limiting rope frame and the side traction rope are slidably connected through the connection. The length of the side traction rope is equal to the distance between the piston cover plate and the connecting frame plus the sliding length of the biofilm reaction tube.

[0013] Preferably, a positive traction rope is slidably connected through the connecting frame on the other side, and positive limiting baffles are fixedly connected to both ends of the positive traction rope. A positive limiting rope frame is slidably connected through the positive traction rope, and the positive limiting rope frame is fixedly connected to the positive reaction tube. The end of the positive traction rope near the partition plate is slidably connected through the partition plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention utilizes the different contact areas between the brewing wastewater on both sides of the separator and the biofilm reactor tube, resulting in different oxygen content on both sides. The amount of biogas generated, combined with the tension of the pressure-reducing spring, causes the sliding piston cover on the side with higher biogas production to slide upwards, pulling the biofilm reactor tube to that side. This, along with the forward sliding piston ring, side sliding piston ring, agitating piston ring, and sliding rod, forms a piston-sealed structure that separates the two sides of the separator. This allows the side with higher biogas production to accelerate the decomposition of organic matter by microorganisms. Simultaneously, the movement of the biofilm reactor tube causes the side sliding piston ring or forward sliding piston ring to push the brewing wastewater on the other side towards the moving side of the biofilm reactor tube. Through the reciprocating sliding of the biofilm reactor tube, the brewing wastewater on both sides can accelerate the reaction. Furthermore, the brewing wastewater flows out through the arc-shaped groove of the agitating piston ring as it slides through the biofilm reactor tube, mixing with the original brewing wastewater and creating a stirring effect.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1-10 As shown, the present invention provides a technical solution: an apparatus for degrading organic matter in brewing wastewater using microorganisms. It includes a forward reaction tube 10, a partition plate 20 fixedly connected inside the forward reaction tube 10, reaction side tubes 101 fixedly connected to both sides of the forward reaction tube 10, symmetrically distributed support frames 301 fixedly connected to the reaction side tubes 101, and a top cover 30 fixedly connected between the support frames 301.

[0032] Among them, symmetrically distributed stirring piston rings 203 are fixedly connected to both sides of the partition plate 20, and a biofilm reaction tube 201 is slidably connected inside the partition plate 20. A positive sliding piston ring 2011 is slidably connected to the outer contour of the biofilm reaction tube 201 inside the stirring piston ring 203 on one side, and a side sliding piston ring 2012 is slidably connected to the outer contour of the biofilm reaction tube 201 inside the stirring piston ring 203 on the other side.

[0033] A fixed shaft 304 is fixedly connected to the lower side of the top cover 30, and a transmission piston sleeve 303 is slidably connected to the fixed shaft 304. A sliding piston air cover 302 is slidably connected to the transmission piston sleeve 303.

[0034] Using the above method: the brewing wastewater in the biofilm reaction tube 201 reacts with the brewing wastewater in the forward reaction tube 10 and the reaction side tube 101. Microorganisms on the biofilm reaction tube 201 absorb the organic matter in the brewing wastewater and generate biogas. The biogas gradually converges into the reaction side tubes 101 via the wastewater. The liquid surface in the reaction side tube 101 breaks, temporarily collecting the biogas between the sliding piston gas cover 302 and the liquid surface. As the biogas accumulates, it gradually pushes the sliding piston gas cover 302 upwards. Because the initial position of the biofilm reaction tube 201 is close to the direction of the forward traction rope 306, the biogas generated in the area where the forward traction rope 306 is located is greater than that generated in the area where the side traction rope 305 is located. Consequently, the sliding piston gas cover 302 in the area where the forward traction rope 306 is located rises to a higher height, until it reaches a high... In the reaction side pipe 101, biogas is discharged and collected outside the sliding piston gas cover 302. As the sliding piston gas cover 302 moves upward, it drives the transmission piston sleeve 303 to move synchronously. After the biogas is discharged, the sliding piston gas cover 302 falls into the reaction side pipe 101. However, the descent speed of the transmission piston sleeve 303 is lower than that of the sliding piston gas cover 302, causing the sliding piston gas cover 302 to separate from the transmission piston sleeve 303. Then, the biogas continues to be discharged and collected through the gap between the transmission piston sleeve 303 and the sliding piston gas cover 302 until the biogas generation on the other side is higher than that on this side. This causes the biofilm reaction pipe 201 to move to the other side, thereby driving the transmission piston sleeve 303 to reset. This creates the effect of the biofilm reaction pipe 201 sliding repeatedly on both sides, which creates a stirring effect on the brewing wastewater on both sides.

[0035] like Figure 3 and 5 As shown, an inlet pipe 102 is fixedly connected to the lower side of the forward reaction tube 10. The agitating piston ring 203 is slidably connected to the forward sliding piston ring 2011 and the side sliding piston ring 2012. The two ends of the biofilm reaction tube 201 are fixedly connected to intercepting rings 2013. The forward sliding piston ring 2011 has a groove with the same diameter as the intercepting ring 2013 on the side away from the partition plate 20. The side sliding piston ring 2012 has an annular groove with the same diameter as the intercepting ring 2013 on the side away from the partition plate 20. The agitating piston ring 203 has a retaining ring with a diameter smaller than that of the forward sliding piston ring 2011 and the side sliding piston ring 2012 on the side away from the partition plate 20. The diameters of the forward sliding piston ring 2011 and the side sliding piston ring 2012 are the same as the inner diameter of the agitating piston ring 203.

[0036] Using the above method: As the biofilm reaction tube 201 slides back and forth, the forward sliding piston ring 2011 and the side sliding piston ring 2012 slide within the agitating piston ring 203. Since the forward sliding piston ring 2011 and the side sliding piston ring 2012 have annular grooves on the side away from the partition plate 20, when the forward sliding piston ring 2011 is limited by the agitating piston ring 203, the side sliding piston ring 2012 continues to slide with the biofilm reaction tube 201, squeezing the wastewater between the forward sliding piston ring 2011 and the side sliding piston ring 2012 and moving it in the sliding direction of the biofilm reaction tube 201 until the side sliding piston ring 2012 is intercepted by the partition plate 20. The partition plate 20 and the side sliding piston ring 2012, together with the agitating piston ring 203, form a piston structure, thereby separating the two sides of the partition plate 20.

[0037] like Figure 2-3 As shown, the agitator piston ring 203 has circumferentially arrayed arc-shaped grooves inside. The arc-shaped grooves of the agitator piston ring 203 connect the inside and outside of the agitator piston ring 203. The length of the arc-shaped grooves of the agitator piston ring 203 is less than half the length of the agitator piston ring 203 and is located on the side of the agitator piston ring 203 away from the partition plate 20.

[0038] Using the above method: As the biofilm reaction tube 201 slides back and forth, the side sliding piston ring 2012 or the front sliding piston ring 2011 squeezes the brewing wastewater towards the sliding direction of the biofilm reaction tube 201. Then, the brewing wastewater is discharged from the arc-shaped groove inside the stirring piston ring 203, which connects the inside and outside of the stirring piston ring 203. Due to the arc-shaped structure of the arc-shaped groove, the wastewater is discharged from the arc-shaped groove inside the stirring piston ring 203 with a certain angle and speed. During the mixing of the two wastewaters, the brewing wastewater is stirred.

[0039] like Figure 5 As shown, an inner partition ring 204 is fixedly connected inside the biofilm reaction tube 201. A sliding rod 2041 is slidably connected inside the inner partition ring 204. Piston cover plates 2042 are fixedly connected to both ends of the sliding rod 2041. The diameter of the piston cover plate 2042 is smaller than the inner diameter of the biofilm reaction tube 201. Symmetrically distributed fan-shaped grooves are opened on the inner partition ring 204. The diameter of the fan-shaped grooves of the inner partition ring 204 is smaller than the diameter of the piston cover plate 2042.

[0040] Using the above method: As the reaction proceeds on both sides, when the biogas volume on the other side is large, another sliding method of the biofilm reaction tube 201 is that the sliding rod 2041 drives the inner partition ring 204 and the biofilm reaction tube 201 to slide. The piston cover plate 2042 and the inner partition ring 204 cooperate with the biofilm reaction tube 201 to form a closed structure, which separates the two sides of the partition plate 20 from the inside. At the same time, the biofilm reaction tube 201, the stirring piston ring 203 and the positive sliding piston ring 2011 form a closed piston structure to separate the two sides of the partition plate 20.

[0041] like Figure 6 As shown, a pressure-reducing tension spring 3021 is provided between the sliding piston gas cover 302 and the top cover 30 around the fixed shaft 304. The pressure-reducing tension spring 3021 is fixedly connected to the top cover 30 and the sliding piston gas cover 302. The tension of the pressure-reducing tension spring 3021 is less than the tension required for the biofilm reaction tube 201 and the inner separator ring 204 to move horizontally.

[0042] Using the above method: biogas accumulates on the lower side of the sliding piston gas cover 302, causing the sliding piston gas cover 302 to move upward, and at the same time, it causes the transmission piston sleeve 303 to move synchronously. Since it is difficult to drive the sliding of the biofilm reaction tube 201 by the amount of biogas generated alone, the pressure required for the biogas to lift the sliding piston gas cover 302 is reduced by cooperating with the tension of the pressure reducing spring 3021.

[0043] like Figure 6-8 As shown, a connecting frame 3031 is fixedly connected to the lower end of the piston sleeve 303 on one side. A side traction rope 305 is slidably connected through the connecting frame 3031. A side limiting baffle 3052 is fixedly connected to one end of the side traction rope 305 away from the partition plate 20. The other end of the side traction rope 305 is fixedly connected to the piston cover plate 2042. A side limiting rope frame 3051 is fixedly connected inside the positive reaction tube 10. The side limiting rope frame 3051 and the side traction rope 305 are slidably connected through the side traction rope 305. The length of the side traction rope 305 is equal to the distance between the piston cover plate 2042 and the connecting frame 3031 plus the sliding length of the biofilm reaction tube 201.

[0044] On the other side, a positive traction rope 306 is slidably connected to the connecting frame 3031. Both ends of the positive traction rope 306 are fixedly connected to positive limiting baffles 3062. The positive traction rope 306 is slidably connected to a positive limiting rope frame 3061. The positive limiting rope frame 3061 is fixedly connected to the positive reaction tube 10. The end of the positive traction rope 306 near the partition plate 20 is slidably connected to the partition plate 20. The length of the positive traction rope 306 is equal to the distance between the limiting ring frame 202 and the connecting frame 3031 plus the sliding length of the biofilm reaction tube 201.

[0045] Using the above method: the pressure of biogas lifts the sliding piston gas cover 302, which in turn drives the transmission piston sleeve 303 to move synchronously. This causes the connecting frame 3031 to drive the side traction rope 305 to move synchronously. The side traction rope 305 then drives the piston cover plate 2042 near the side traction rope 305 to move, which in turn causes the sliding rod 2041 and the piston cover plate 2042 on the other side to slide. This causes the inner separator ring 204 and the biofilm reaction tube 201 to move synchronously. Similarly, the other side sliding piston gas cover... The lifting of 302 causes the transmission piston sleeve 303 and the connecting frame 3031 to move synchronously. In turn, the positive traction rope 306, together with the positive limit baffle 3062, drives the limit ring frame 202 and the biofilm reaction tube 201 to slide horizontally in the direction of the positive traction rope 306. Due to the limitation of the length of the side traction rope 305 and the positive traction rope 306, the pressure relief springs 3021 on both sides are prevented from engaging in a tug-of-war during the horizontal movement of the biofilm reaction tube 201 by the side traction rope 305 or the positive traction rope 306.

[0046] like Figure 8-9 As shown, a limiting butterfly plate 3041 is fixedly connected to the lower end of the fixed shaft 304. The limiting butterfly plate 3041 has a through groove in the direction corresponding to the connecting frame 3031. The through groove of the limiting butterfly plate 3041 connects the upper side of the sliding piston air cover 302 and the lower side of the limiting butterfly plate 3041.

[0047] Using the above method: when the sliding piston gas cover 302 slides up to a height higher than the reaction side pipe 101, biogas is discharged and collected from the lower side of the sliding piston gas cover 302, so that the sliding piston gas cover 302 will quickly return to its original position. By making the speed at which the transmission piston sleeve 303 returns to its original position lower than that of the sliding piston gas cover 302, a gap is created between the sliding piston gas cover 302 and the fixed shaft 304, so that biogas can still be discharged and collected.

[0048] like Figure 8-10 As shown, a symmetrically distributed slow-descent shaft 307 is fixedly connected to the lower end of the top cover 30, and an array of slow-descent rubber sleeves 3071 are fixedly connected to the slow-descent shaft 307. The slow-descent shaft 307 and the transmission piston sleeve 303 are slidably connected through each other.

[0049] The transmission piston sleeve 303 has symmetrically distributed slow-descent holes. The diameter of the slow-descent holes on the transmission piston sleeve 303 is larger than the diameter of the slow-descent shaft 307, and the diameter of the slow-descent holes on the transmission piston sleeve 303 is smaller than the maximum diameter of the slow-descent rubber sleeve 3071.

[0050] Using the above method: Because after the sliding piston gas cover 302 slides upwards above the reaction side pipe 101, biogas is discharged and collected from the lower side of the sliding piston gas cover 302, causing the sliding piston gas cover 302 to quickly return to its original position below the reaction side pipe 101. At this time, the amount of biogas on the other side is still relatively small, resulting in the sliding piston gas cover 302 repeatedly moving up and down, only able to discharge and collect a small portion of biogas each time. This fails to achieve the effect of the biofilm reaction pipe 201 sliding back and forth, thus affecting the sliding piston gas cover 302. After the transmission piston sleeve 303 slides upward to its limit position, the slow-descent hole on the transmission piston sleeve 303 engages with the slow-descent shaft 307. When the sliding piston gas cover 302 returns to its original position downward, it is resisted by the slow-descent shaft 307 and the slow-descent rubber sleeve 3071, causing the transmission piston sleeve 303 to return to its original position at a lower speed than the sliding piston gas cover 302. This causes the sliding piston gas cover 302 to separate from the transmission piston sleeve 303, and the biogas continues to be discharged outward through the gap between the sliding piston gas cover 302 and the fixed shaft 304.

[0051] Working principle and usage process of this invention:

[0052] Example 1:

[0053] First, the biofilm reactor 201 is positioned as shown in the figure. Then, brewing wastewater is injected into the forward reaction tube 10 through the inlet pipe 102 until the liquid level of the brewing wastewater is higher than the inner diameter of the forward reaction tube 10. The organic matter in the brewing wastewater then reacts with the microorganisms in the biofilm on the biofilm reactor 201 to produce biogas. Because the biofilm reactor 201 is not in the center, the contact area between the brewing wastewater and the biofilm reactor 201 on both sides of the separator 20 is different, resulting in different reaction rates and thus varying biogas production. This causes the amount of biogas accumulated below the sliding piston gas cover 302 on the side where the positive traction rope 306 is located to be greater than the amount of biogas on the other side. The pressure of the biogas, combined with the tension of the corresponding pressure-reducing spring 3021, causes the sliding piston gas cover 302 to slide upward, which in turn causes the transmission piston sleeve 303 to slide synchronously. This, in turn, causes one end of the positive traction rope 306 to slide synchronously through the connecting frame 3031, causing the other end of the positive traction rope 306 to drive the limiting ring frame 202 to move, so that the biofilm reaction tube 201 continues to slide in the direction of the positive traction rope 306.

[0054] Until the biofilm reaction tube 201 slides to its limit position, the sliding piston gas cover 302 drives the transmission piston sleeve 303 to slide until the height of the sliding piston gas cover 302 is higher than the upper surface of the reaction side tube 101, so that the biogas under the sliding piston gas cover 302 is discharged outward and collected, causing the sliding piston gas cover 302 to reset downward. Since the transmission piston sleeve 303 moves upward and cooperates with the slow-descent shaft 307 and the slow-descent rubber sleeve 3071, the maximum diameter of the slow-descent rubber sleeve 3071 is smaller than the slow-descent hole on the transmission piston sleeve 303, so that the downward reset of the transmission piston sleeve 303 is hindered by the slow-descent rubber sleeve 3071, and the speed is lower than that of the sliding piston gas cover 302. As a result, the biogas continues to be discharged and collected through the gap between the sliding piston gas cover 302 and the fixed shaft 304.

[0055] Simultaneously, as the biofilm reaction tube 201 slides, the forward sliding piston ring 2011 is obstructed by the retaining ring of the agitating piston ring 203, and the side sliding piston ring 2012 continues to slide under the push of the intercepting ring 2013 on the biofilm reaction tube 201. This causes the brewing wastewater in the agitating piston ring 203 to be squeezed in the sliding direction of the biofilm reaction tube 201, increasing the amount of brewing wastewater in the agitating piston ring 203 that is in contact with the forward sliding piston ring 2011. This wastewater is then discharged through the arc-shaped groove on the agitating piston ring 203. Due to the structure of the arc-shaped groove, the discharged brewing wastewater has a certain initial velocity and angular velocity. Therefore, when the two types of brewing wastewater are mixed, they have a stirring effect on the brewing wastewater on the side where the traction rope 306 is located.

[0056] As biogas is continuously discharged from one side of the positive traction rope 306, when the biogas volume is higher on the side where the side traction rope 305 is located, the side traction rope 305 pulls the piston cover plate 2042 and the sliding rod 2041. Consequently, the piston cover plate 2042 on the other side squeezes the inner partition ring 204, causing the biofilm reaction tube 201 to slide towards the side traction rope 305. This allows the biofilm reaction tube 201 to come into more contact with the brewing wastewater in the area where the side traction rope 305 is located. At the same time, the positive sliding piston ring 2011 squeezes and stirs the brewing wastewater in the piston ring 203 towards the area where the side traction rope 305 is located, which also creates a stirring effect on the brewing wastewater.

[0057] Example 2:

[0058] The biofilm reactor 201 reacts with the brewing wastewater in the forward reaction tube 10 and the reaction side tube 101. Microorganisms on the biofilm reactor 201 absorb the organic matter in the wastewater and generate biogas. The biogas gradually converges into the reaction side tubes 101 via the wastewater. At the liquid surface in the reaction side tube 101, the biogas is temporarily collected between the sliding piston gas cover 302 and the liquid surface. As the biogas accumulates, it gradually pushes the sliding piston gas cover 302 upwards. Because the initial position of the biofilm reactor 201 is close to the direction of the forward traction rope 306, the biogas generated in the area where the forward traction rope 306 is located is greater than that generated in the area where the side traction rope 305 is located. Consequently, the sliding piston gas cover 302 in the area where the forward traction rope 306 is located rises to a higher height, until it exceeds the reaction side tube 101. In the side pipe 101, biogas is discharged and collected outside the sliding piston gas cover 302. As the sliding piston gas cover 302 moves upward, it drives the transmission piston sleeve 303 to move synchronously. After the biogas is discharged, the sliding piston gas cover 302 falls into the reaction side pipe 101. However, the descent speed of the transmission piston sleeve 303 is lower than that of the sliding piston gas cover 302, causing the sliding piston gas cover 302 to separate from the transmission piston sleeve 303. Then, the biogas continues to be discharged and collected through the gap between the transmission piston sleeve 303 and the sliding piston gas cover 302 until the biogas generation on the other side is higher than that on this side. This causes the biofilm reaction pipe 201 to move to the other side, thereby driving the transmission piston sleeve 303 to reset. This creates the effect of the biofilm reaction pipe 201 sliding repeatedly on both sides, which creates a stirring effect on the brewing wastewater on both sides.
