[0034] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] Reference Figures 1 to 4The present invention provides a biochemical reactor, comprising a housing 1, an air supply system 2, an oxygen supply system 3, a pumping system 4 and a biofilm carrier filler 5.

[0036] The box body 1 is preferably a rectangular parallelepiped having a top plate, a bottom plate and four side plates, the length is preferably twice the width, and the height is preferably 1.25 times the width. A first perforated plate 11 and a second perforated plate 12 are provided inside the box body 1. The first perforated plate 11 and the second perforated plate 12 sequentially divide the inside of the box body 1 from front to back to form a first processing interval 13, a second processing interval 14 and an outlet interval 15;

[0037] The side plate at the front end of the box body 1 is a water inlet plate 16, and a water inlet hole 161 is opened on the water inlet plate 16. The number of the water inlet holes 161 is multiple and evenly distributed. The water outside the box body 1 can enter the first treatment interval 13 through the water inlet holes 161;

[0038] The first perforated plate 11 is provided with a plurality of first water holes which are evenly distributed, and the water in the first treatment interval 13 can pass through the first water holes and enter the second treatment interval 14;

[0039] The second perforated plate 12 is provided with a plurality of second water holes which are evenly distributed. Water in the second treatment interval 14 can pass through the second water holes and enter the outlet interval 15.

[0040] The sizes of the water inlet hole 161, the first water hole and the second water hole are all smaller than the size of the biofilm carrier filler 5. While allowing water to flow freely, it can ensure that the biofilm carrier filler 5 is always located inside the first treatment interval 13 and the second treatment interval 14 to prevent the biofilm carrier filler 5 from being discharged.

[0041] An air supply system 2 is provided in both the first treatment interval 13 and the second treatment interval 14. The air supply system 2 can be connected to the air supply equipment located outside the box 1. The air supply system 2 can inject pressurized air into the first treatment interval 13 and the second treatment interval 14 to form a stirring effect, thereby giving the biofilm carrier filler 5 filled in the first treatment interval 13 and the second treatment interval 14 the ability to move.

[0042] The first treatment interval 13 and the second treatment interval 14 are both provided with an oxygen supply system 3, which can be connected to an oxygen supply device located outside the box 1, and the oxygen supply system 3 can inject pressurized oxygen into the first treatment interval 13 and the second treatment interval 14, and the oxygen can increase the dissolved oxygen level in the water body.

[0043] The outlet compartment 15 forms an additional area into which the treated water can flow. The pumping system 4 is arranged in the outlet compartment 15 and can pass through the top of the housing 1. The pumping system 4 can transport the treated water from the outlet compartment 15 back to the water body. In this way, the treated water can be directly discharged into the water body in which the housing 1 is immersed, thereby effectively realizing circulation.

[0044] At the same time, since the outlet interval 15 forms a separate area, when the pumping system 4 is operating, the pumping system 4 can directly extract water from the outlet interval 15 without extracting the biofilm carrier filler 5 in the second treatment interval 14 on the other side. Due to the presence of the second perforated plate 12, the biofilm carrier filler 5 will still remain in the second treatment interval 14;

[0045] Also, for bodies of water such as ponds, this may provide additional flow which prevents stratification of the pond, thereby reducing odor from hydrogen sulfide formed in anaerobic sediments, and may also break up the surface of the pond, which in turn may result in further aeration.

[0046] The biofilm carrier filler 5 is arranged in the first treatment interval 13 and the second treatment interval 14. The biofilm carrier filler 5 can also be called a filter medium unit. The biofilm carrier filler 5 can provide a growth surface for the biofilm containing bacteria. Since the biofilm carrier filler 5 is immersed in the container, the impurities in the water and the microorganisms on the biofilm carrier filler 5 can form an optimal contact effect.

[0047] The specific size and shape of the biofilm carrier filler 5 are not specifically limited. In this embodiment, the preferred surface area is >500m 2 / m 3 The medium can reach up to 750m 2 / m 3 ;

[0048] The form of the supporting medium is not specifically limited. In this embodiment, a small plastic sphere or tube is preferred. The plastic medium is light and can float in water. The specific weight of the particles is close to 1.0 kg / dm 3 , its density is usually between 0.92 and 1.08 kg / dm 3 within the scope;

[0049] In this embodiment, about 50% to 70% of the volume of the first processing space 13 and the second processing space 14 can be filled with the above-mentioned medium.

[0050] The biological and biochemical reactor can be directly immersed in the water body, and the water in the water body can enter the first treatment interval 13, the second treatment interval 14 and the outlet interval 15 inside the box body 1 in sequence, and mix with the biofilm carrier filler 5 in the first treatment interval 13 and the second treatment interval 14. During the mixing process, the air supply system 2 can inject pressurized air to form a stirring effect. The biofilm carrier filler 5 can be randomly mixed by aeration at the bottom of the box body 1 to avoid clogging and generating hydrodynamic forces, giving the biofilm carrier filler 5 movement ability, so that the biofilm carrying surface of the carrier element circulates, and the thickness of the biofilm is positively affected by shear force. The oxygen supply system 3 can inject pressurized oxygen to increase the dissolved oxygen level in the water body, and then it is discharged by the pumping system 4 in the outlet interval 15;

[0051] The water in the water body can be effectively treated directly on site, and the treated water can be directly recycled back into the water body. Compared with ponds or similar closed water environments, bioreactors are more compact, occupy less space, are easy to use, do not require much maintenance, and are not prone to clogging or overflowing;

[0052] Bioreactors can be placed directly in ponds or water bodies with intensive aquaculture production and can be used not only for nitrification but also for any purification technology that involves biodegradation from water bodies.

[0053] As an optional embodiment, the air supply system 2 includes a first air supply pipe 21, a first air mixing ring pipe 22, a second air supply pipe 23 and a second air mixing ring pipe 24, and the first air supply pipe 21 and the second air supply pipe 23 are both connected to the air supply equipment;

[0054] The other end of the first air supply pipe 21 extends into the box 1 and is connected to the first aeration ring pipe 22 located at the bottom of the first processing interval 13. The first aeration ring pipe 22 is evenly provided with first air supply ports. The first air supply pipe 21 is provided with a first air supply valve 211. The first air supply valve 211 can adjust the air supply volume of the first air supply pipe 21. Here, the first air supply valve 211 is preferably a ball valve.

[0055] The other end of the second air supply pipe 23 extends into the box body 1 and is connected to the second aeration ring pipe 24 located at the bottom of the second processing interval 14. The second aeration ring pipe 24 is evenly provided with second air supply ports. The second air supply pipe 23 is provided with a second air supply valve 231. The second air supply valve 231 can adjust the air supply amount of the second air supply pipe 23. Here, the second air supply valve 231 is preferably a ball valve.

[0056] The first gas supply valve 211 and the second gas supply valve 231 can realize the independent control of the corresponding pipelines, thereby independently controlling the aeration effect of the first processing interval 13 and the second processing interval 14;

[0057] The pressurized air delivered by the external air supply device can be delivered to the first aeration loop 22 through the first air supply pipe 21, and injected into the treated water of the first treatment interval 13 from a plurality of first air supply ports, and delivered to the second aeration loop 24 through the second air supply pipe 23, and injected into the treated water of the second treatment interval 14 from a plurality of second air supply ports;

[0058] In this embodiment, the external air supply equipment can preferably be a compressor, a blower or other similar air pressurizing device located remotely from the box 1. In addition, it can also be transported through a hose by any aeration device far away from the box 1, such as a land-based aeration device located next to a pond.

[0059] The first aeration ring pipe 22 and the second aeration ring pipe 24 are both in the form of ring pipes and are both located at the bottom of the housing 1. With such an arrangement, the generated bubbles can move upward from the bottom of the housing 1 through the reactor housing 1, and the overall moving path is longer, providing better mixing and oxidation.

[0060] The pressurized air injected by the first aeration loop 22 and the second aeration loop 24 can cause the agitation of the treated water in the first treatment interval 13 and the second treatment interval 14 in the form of a jet flow, respectively, to transmit motion to the biofilm carrier filler 5, especially to perform continuous motion within the volume range inside the housing 1, so that the biofilm carrier filler 5 is thoroughly mixed in the first treatment interval 13 and the second treatment interval 14, thereby maintaining good contact between the biofilm growing on the filler and the matrix in the pool water, forming an optimal arrangement;

[0061] In addition, the stirring here can keep the filler in continuous motion, forming a scrubbing effect, preventing blockage and avoiding the shedding of excess biomass. Since the biofilm carrier filler 5 is not stationary, but moves with the flow caused by the jet flow, if the biofilm carrier filler 5 is blocked, it can also be directly replaced with fresh medium, which is more convenient.

[0062] In addition, in addition to the function of stirring the biofilm carrier filler 5, the air supply system 2 is equivalent to carrying oxygen while injecting pressurized air, providing support for the aerobic biological process inside the box 1. The aeration process enables positive adjustment between oxygen consumption and supply, so the first aeration ring pipe 22 and the second aeration ring pipe 24 have both stirring and aeration functions.

[0063] As an optional embodiment, the oxygen supply system 3 includes a first oxygen supply pipe 31, a first oxygen supply ring pipe 32, a second oxygen supply pipe 33 and a second oxygen supply ring pipe 34, and the first oxygen supply pipe 31 and the second oxygen supply pipe 33 are both connected to the oxygen supply equipment;

[0064] The other end of the first oxygen supply pipe 31 extends into the box 1 and is connected to the first oxygen supply ring pipe 32 located at the bottom of the first processing interval 13. The first oxygen supply ring pipe 32 is evenly provided with first oxygen supply ports. The first oxygen supply pipe 31 is provided with a first oxygen supply valve 311. The first oxygen supply valve 311 can adjust the gas supply of the first oxygen supply pipe 31. Here, the first oxygen supply valve 311 is preferably a ball valve.

[0065] The other end of the second oxygen supply pipe 33 extends into the box 1 and is connected to the second oxygen supply ring pipe 34 located at the bottom of the second processing interval 14. The second oxygen supply ring pipe 34 is evenly provided with second oxygen supply ports. The second oxygen supply pipe 33 is provided with a second oxygen supply valve 331. The second oxygen supply valve 331 can adjust the gas supply of the second oxygen supply pipe 33. The second oxygen supply valve 331 is preferably a ball valve.

[0066] The first oxygen supply valve 311 and the second oxygen supply valve 331 can realize the independent control of the corresponding pipelines, so as to independently control the oxygen supply effect and the dissolved oxygen level of the first treatment interval 13 and the second treatment interval 14;

[0067] The pressurized oxygen delivered by the external gas supply device can be delivered to the first oxygen supply loop 32 through the first oxygen supply pipe 31, and injected into the treated water of the first treatment interval 13 from a plurality of first oxygen supply ports, and delivered to the second oxygen supply loop 34 through the second oxygen supply pipe 33, and injected into the treated water of the second treatment interval 14 from a plurality of second oxygen supply ports;

[0068] In this embodiment, the external oxygen supply equipment can preferably be provided by an oxygen cylinder, liquid oxygen system or other similar oxygen generating device located remotely from the box 1, and can also be transported from the oxygen generating device through a hose, such as a land-based oxygen generating device located next to a pond.

[0069] The first oxygen supply loop 32 and the second oxygen supply loop 34 are both in the form of loops and are both located at the bottom of the housing 1. With such an arrangement, the injected oxygen jet can move upward from the bottom of the housing 1 through the reactor housing 1, and the overall moving path is longer, providing better mixing and oxidation, thereby increasing the dissolved oxygen levels in the first treatment interval 13 and the second treatment interval 14.

[0070] The pressurized oxygen injected by the first aeration loop 22 and the second aeration loop 24 can affect the dissolved oxygen level in the first treatment space 13 and the second treatment space 14, respectively, in the form of oxygen jets.

[0071] As an optional embodiment, the pumping system 4 includes a water pump 41, a discharge pipe 42 and a discharge valve 43. The water pump 41 is arranged at the bottom of the outlet interval 15. The discharge pipe 42 includes a vertical section and a horizontal section connected to each other. The bottom end of the vertical section is connected to the water pump 41. The discharge valve 43 is arranged on the horizontal section. One end of the horizontal section away from the vertical section is located above the water surface.

[0072] The water pump 41 can pump the treated water in the outlet compartment 15 to the discharge pipe 42, and discharge the treated water from the tank 1 through the discharge pipe 42 above the water surface, so that the treated water can be circulated back to the pond in a directional manner, and the discharge valve 43 can adjust the flow rate of the pumping system 4;

[0073] With this arrangement, pool water can enter the reactor from the front end and can be discharged from the reactor from the rear end. The pool water can form a directional circulating water flow, ensuring that the biofilm grown on the carrier filler can have good contact with the matrix in the pool water.

[0074] As an optional embodiment, the bio-biochemical reactor further includes a buoyancy box 61, which is connected to the outside of the housing 1, and the inside of the buoyancy box 61 is inflated and sealed. The inflated and sealed buoyancy box 61 can make the bio-biochemical reactor as a whole have better buoyancy, so that the bio-biochemical reactor can float in the pond and make the discharge pipe 42 of the pumping system 4 higher than the water level;

[0075] The size of the buoyancy box 61 can be flexibly adjusted and replaced according to actual use requirements, so as to correspond to different buoyancy sizes and to correspond to different expected water levels. For example, a buoyancy box 61 with smaller buoyancy can be selected to make the box body 1 immersed deeper, or a buoyancy box 61 with larger buoyancy can be selected to make the box body 1 float better. Therefore, the buoyancy box 61 is preferably connected to the outside of the box body 1 in a detachable manner to facilitate the disassembly and assembly of the buoyancy box 61 and the replacement of buoyancy boxes 61 of different sizes;

[0076] In this embodiment, the number of the buoyancy boxes 61 is preferably four, and the four buoyancy boxes 61 are respectively located on the four sides of the box body 1, and the structure is relatively symmetrical and therefore more stable.

[0077] As an optional implementation, on the basis of providing a buoyancy tank 61, the bio-biochemical reactor also includes a stabilizing weight structure 62, and the stabilizing weight structure 62 is connected to the outside of the box body 1. If necessary, the overall weight of the bio-biochemical reactor can be stabilized by the stabilizing weight structure 62, so as to cooperate with the buoyancy tank 61 to adjust the level and depth of the bio-biochemical reactor placed in the pond. In this embodiment, four stabilizing weight structures 62 are preferably provided at the four corners of the box body 1. The structure is more symmetrical and therefore more stable. The stabilizing weight structure 62 can be a columnar structure, such as a solid iron column or other heavy objects. There are many choices and no specific restrictions.

[0078] As an optional implementation, the biochemical reactor also includes a pressure relief system 7, which includes a pressure relief pipe 71 and a pressure relief valve 72. One end of the pressure relief pipe 71 is connected to the top of the box body 1 and communicates with the interior of the box body 1. The other end of the pressure relief pipe 71 is located above the water surface. The pressure relief valve 72 is arranged on the pressure relief pipe 71. When the pressure inside the box body 1 exceeds the normal range, the pressure relief valve 72 can be opened to make the pressure relief pipe 71 conductive and discharge the excess pressure inside the box body 1. When water enters and exits the box body 1, the positive pressure or negative pressure generated in the box body 1 can be effectively relieved to ensure the normal use of the biochemical reactor.

[0079] As an optional embodiment, the biological and biochemical reactor also includes a drainage system 8, which includes a drain pipe 81 and a drain valve 82. One end of the drain pipe 81 is connected to the bottom of the box body 1 and is communicated with the interior of the box body 1. The drain valve 82 is arranged on the drain pipe 81. The drain valve 82 can control the opening and closing of the drain pipe 81. When the pond as a whole needs to be drained, the water inside the box body 1 also needs to be drained synchronously. Therefore, timely synchronous drainage can be achieved through the additional drainage system 8.

[0080] As an optional embodiment, it also includes a support member 9, which is connected to the bottom of the box body 1 to raise the height of the bottom of the box body 1. Such a configuration can effectively prevent the drain pipe 81 and the drain valve 82 of the drainage system 8 from being damaged when the bottom contacts the bottom of the pool body. It can also prevent the drain pipe 81 from being blocked by sediment at the bottom of the pond, thereby ensuring the normal use of the drainage system 8.

[0081] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
