Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to a bacterial agent spreading device for sewage treatment. Background Art

[0002] Sewage treatment projects are an important part of urban municipal construction, industrial enterprise construction or sewage treatment, and their construction must be carried out in accordance with the national basic construction procedures. The treatment process to be adopted is determined based on the water quality and quantity of sewage, the economic value of recycling, discharge standards and other social and economic conditions, after analysis and comparison, and if necessary, experimental research.

[0003] In the process of sewage treatment, it is necessary to denitrify the sewage. In the prior art, denitrifying bacteria are usually added to the sewage. For example, the utility model patent with application number CN202121719774.1 discloses a denitrifying agent adding device for a sewage treatment tank, including a water reservoir, the outside of the water reservoir is connected to a water pipeline, the inside of the water reservoir is provided with a stirring device, the top of the water reservoir is provided with an agent injection device, and a water volume alarm device is installed inside the agent injection device.

[0004] In the prior art, in the process of sewage treatment, some particles with lower density in the sewage are easy to float on the surface of the sewage, and foam is also easy to appear on the surface of the sewage during sewage treatment. As a result, in the process of spraying the denitrifying bacteria agent, the denitrifying bacteria agent is easily hindered by the floating particles and foam on the upper layer of the sewage, and it is difficult to quickly enter the sewage, thereby increasing the difficulty of sewage treatment.

[0005] To this end, the present invention proposes a bacterial agent spreading device for sewage treatment to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a bacterial agent spreading device for sewage treatment.

[0007] In order to achieve the above purpose, the technical solution adopted by the present invention is: a bacterial agent spreading device for sewage treatment, comprising:

[0008] A sewage tank, wherein a shell is slidably connected to the top of the sewage tank;

[0009] A rotating shell, the rotating shell is rotatably connected to the bottom end of the shell body;

[0010] Two spreading arms, the two spreading arms are symmetrically fixed and connected to the outer side arms of the rotating shell, and the bottom array of the spreading arms is provided with spraying holes;

[0011] A pumping mechanism, wherein the pumping mechanism is used to pump the denitrifying bacteria agent into two spreading arms, and spray the denitrifying bacteria agent into the sewage through the spreading arms;

[0012] Two sealing covers, the top ends of the two sealing covers are fixedly connected to the outer arms of the spreading arm, and the bottom ends of the sealing covers extend into the sewage to prevent particles floating on the surface of the sewage from entering the sealing covers;

[0013] a first scraper, wherein the first scraper is slidably connected in the sealing cover, the bottom end of the first scraper is located on the sewage surface, a second linear drive mechanism is provided in the sealing cover, and the second linear drive mechanism is used to drive the first scraper to move linearly along the sealing cover to scrape off foam on the sewage surface, so that the sprayed denitrification bacteria quickly enter the sewage and fully react with the sewage;

[0014] Specifically, in the prior art, during the treatment of sewage, some particles with lower density in the sewage are easy to float on the surface of the sewage, and foam is also easy to appear on the surface of the sewage during the treatment of sewage, resulting in that during the spraying of the denitrifying bacteria agent, the denitrifying bacteria agent is easily hindered by the floating particles and foam on the upper layer of the sewage, and it is difficult to quickly enter the sewage, thereby increasing the difficulty of sewage treatment. The technical solution can solve the above problems. The specific operation is as follows: the denitrifying bacteria agent is pumped into the rotating shell by a pumping mechanism, and since the two spreading arms are connected to the rotating shell, the denitrifying bacteria agent is sprayed into the sewage through the spraying holes on the spreading arms;

[0015] During the spraying process, the first linear drive mechanism drives the housing to move above the sewage pool, so that the two spreading arms move along the surface of the sewage to evenly spray the denitrification agent on the surface of the sewage pool;

[0016] When the spreading arm moves along the sewage surface, the sealing cover can block the particles floating on the sewage surface to reduce the particles in the spraying range. On the other hand, the sealing cover can eliminate the foam on the sewage surface during the movement, reduce the obstruction to the denitrifying bacteria, and thus facilitate the denitrifying bacteria to quickly enter the sewage for reaction.

[0017] When the spreading arm moves along the sewage surface, the first scraper moves along the sealing cover through the second linear drive mechanism, and the first scraper scrapes off the foam remaining on the sewage surface in the sealing cover, so that the sprayed denitrifying bacteria quickly enters the sewage and fully reacts with the sewage.

[0018] Preferably, it also includes:

[0019] A plurality of sealing mechanisms, wherein the plurality of sealing mechanisms are used to seal the spray holes at corresponding positions, and the sealing mechanisms include:

[0020] Two sealing plates, the two sealing plates are symmetrically slidably connected to the spreading arm, and a spring is fixedly connected between the sealing plate and the spreading arm;

[0021] A pushing mechanism, wherein the pushing mechanism is arranged at the top of the first scraper, and when the first scraper moves to scrape off the foam on the surface of the sewage, the pushing mechanism pushes the sealing plate at the corresponding position to move the sealing plate away from the spraying hole, so that the spraying hole at the corresponding position sprays the denitrifier;

[0022] Specifically, by setting a sealing mechanism, during the movement of the first scraper, the sealing plate on the path is pushed by the pushing mechanism, so that the two sealing plates on the path are sequentially away from the spray holes in the order of arrangement, and the seals of the spray holes at the corresponding positions are cancelled, so that the spray holes spray the denitrifier. During the continued movement of the first scraper, the pushing mechanism leaves the opened sealing plate, and under the elastic action of the spring, the sealing plate is reset, and the spray holes are sealed again to prevent foam from being generated again at the position where the first scraper leaves. If the spray holes continue to spray the denitrifier, they are easily hindered by the foam, which reduces the sinking speed of the denitrifier, thereby helping to reduce unnecessary waste of the denitrifier.

[0023] Preferably, the pushing mechanism comprises:

[0024] A first pushing block, wherein the first pushing block is fixedly connected to the bottom end of the sealing plate, and both ends of the first pushing block are provided with first pushing inclined surfaces;

[0025] Two flip rods, the two flip rods are symmetrically connected to the top side wall close to the connecting rod, and the flip rod has two sections, one of which is a straight rod and the other is an inclined rod;

[0026] Both ends of the flip rod are fixedly connected with a second push block, and the end of the second push block is provided with a second push inclined surface adapted to the first push inclined surface;

[0027] A rotary drive mechanism, the rotary drive mechanism is used to drive the flip rod to flip, when the first scraper moves to the end of the spreading arm, the flip rod is flipped by the rotary drive mechanism, the straight rod is adjusted to be inclined, and the inclined rod is adjusted to be horizontal;

[0028] Specifically, in the process of the first scraper moving from the end of the sealing cover close to the rotating shell to the other end, the second pushing block on the end of the straight rod first pushes the first pushing block on the path, so that the first pushing block on the path drives the sealing plate away from the spraying hole, so that the spraying hole sprays the denitrifying bacteria agent to the position where the foam has been scraped off. After the first scraper moves to the other end of the sealing cover, the rotating drive mechanism is used to flip the flip plate, so that the straight rod of the flip rod becomes inclined and the inclined rod becomes horizontal. When the first scraper is reset, the second pushing block on the end of the inclined rod pushes the first pushing block on the path, so that the sealing plates on the path cancel the sealing of the spraying holes in sequence according to the arrangement order.

[0029] The advantage of this pushing mechanism is that the first scraper can make the spray hole at the corresponding position spray the denitrifying bacteria agent after it is away from the bottom of the spray hole, so that the first scraper can fully remove the foam in the spraying range. On the one hand, it reduces the interference of the first scraper when spraying the denitrifying bacteria agent from the spray hole, and on the other hand, it is helpful to scrape off the foam in the spraying range, reduce the foam content in the spraying range, and make the denitrifying bacteria agent quickly enter the sewage and react with the sewage.

[0030] Preferably, the first flip block is coaxially fixed with the flip rod, and the first flip block is in an inclined state;

[0031] A first push rod, the first push rod being fixedly connected to a side wall close to one end of the sealing cover at a position corresponding to the first flip block;

[0032] A second flip block, the second flip block is coaxially fixed with the flip rod, and the second flip block is in a horizontal state;

[0033] A second push rod, the second push rod being fixedly connected to the side wall close to the other end of the sealing cover at a position corresponding to the second flip block;

[0034] Specifically, by providing a first flip block and a second flip block, in the process of the first scraper moving from the end of the sealing cover close to the rotating shell to the other end, the first flip block is pushed by the first push rod, so that the first flip block rotates to a horizontal state, and the second flip block rotates to an inclined state, thereby causing the flip rod to rotate;

[0035] During the process of the first scraper moving and resetting, the second flip block passes through the second push rod, and under the push of the second push rod, the flip rod is rotated and reset.

[0036] Preferably, it also includes:

[0037] Two groups of scraping members, the scraping members are symmetrically arranged on both sides of the first scraper, each group of the scraping members includes two second scrapers, and the two second scrapers are symmetrically rotatably connected to the side wall of the first scraper;

[0038] A rotary drive assembly, the rotary drive assembly is used to drive the second scraper to flip, so as to further eliminate foam on the surface of the sewage in the sealing cover;

[0039] Specifically, by setting up the second scraper, during the movement of the first scraper, the second scraper is flipped back and forth by rotating the drive assembly to further eliminate the foam on the sewage surface, so that the denitrification bacteria agent can quickly enter the sewage and react with the sewage.

[0040] Preferably, the rotary drive assembly comprises:

[0041] A gear, the gear being coaxially fixed to the top end of the second scraper;

[0042] A rack, the rack being slidably connected to the side wall of the first scraper and meshing with the gear;

[0043] A driving plate, the driving plate being fixedly connected to a side wall of the sealing cover near the top end;

[0044] A wave groove, wherein the wave groove is formed at the top end of the driving plate, and the end of the rack is slidably connected to the wave groove through a connecting pin;

[0045] Specifically, by setting a driving plate and a wave groove, during the movement of the first scraper, the rack moves back and forth along the side wall of the first scraper driven by the wave groove. During the back and forth movement of the rack, the rack drives the gear to rotate, so that the second scraper flips back and forth to further eliminate the foam on the surface of the sewage, so that the denitrification bacteria agent can quickly enter the sewage and react with the sewage.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] The present invention provides a sealing cover and a first scraper. When the spreading arm moves along the sewage surface, the first scraper moves along the sealing cover. On the one hand, the sealing cover blocks particles floating on the sewage surface to reduce particulate matter within the spraying range. On the other hand, the sealing cover can eliminate foam on the sewage surface during movement to reduce obstruction to the denitrifying bacteria agent, thereby facilitating the denitrifying bacteria agent to quickly enter the sewage for reaction. The first scraper scrapes off the residual foam on the sewage surface in the sealing cover, further enabling the sprayed denitrifying bacteria to quickly enter the sewage and fully react with the sewage.

[0048] The present invention provides a sealing plate and a pushing mechanism. When the first scraper moves to scrape off the foam, the sealing plate on the path is pushed by the pushing mechanism to cancel the sealing of the spraying holes at the corresponding positions, so that the spraying holes spray the denitrifier. When the first scraper continues to move, the pushing mechanism leaves the opened sealing plate. Under the elastic action of the spring, the sealing plate is reset to seal the spraying holes again, so as to prevent the position where the first scraper leaves from being regenerated with foam. If the spraying holes continue to spray the denitrifier, they are easily blocked by the foam, which reduces the sinking speed of the denitrifier, thereby helping to reduce unnecessary waste of the denitrifier.

[0049] The present invention is arranged to rotate the driving component during the movement of the first scraper so that the second scraper flips back and forth to further eliminate the foam on the sewage surface, so that the denitrification bacteria agent can quickly enter the sewage and react with the sewage.

DETAILED DESCRIPTION

[0061] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0066] A pumping mechanism, the pumping mechanism is used to pump the denitrifying bacteria agent into the two spreading arms 8, and spray the denitrifying bacteria agent into the sewage through the spreading arms 8;

[0067] Two sealing covers 10, the top ends of the two sealing covers 10 are fixedly connected to the outer arms of the spreading arms 8, and the bottom ends of the sealing covers 10 extend into the sewage to prevent particles floating on the sewage surface from entering the sealing covers 10;

[0068] A first scraper 12 is slidably connected in the sealing cover 10, and the bottom end of the first scraper 12 is located on the sewage surface. A second linear drive mechanism is provided in the sealing cover 10, and the second linear drive mechanism is used to drive the first scraper 12 to move linearly along the sealing cover 10 to scrape off the foam on the sewage surface, so that the sprayed denitrification bacteria quickly enter the sewage and fully react with the sewage;

[0069] Specifically, in the prior art, during the treatment of sewage, some particles with lower density in the sewage are easy to float on the surface of the sewage, and foam is also easy to appear on the surface of the sewage during the treatment of sewage, resulting in that during the spraying of the denitrifying bacteria agent, the denitrifying bacteria agent is easily hindered by the floating particles and foam on the upper layer of the sewage, and it is difficult to quickly enter the sewage, thereby increasing the difficulty of sewage treatment. The technical solution can solve the above problems. The specific operation is as follows: the denitrifying bacteria agent is pumped into the rotating shell 7 by a pumping mechanism. Since the two spreading arms 8 are connected to the rotating shell 7, the denitrifying bacteria agent is sprayed into the sewage through the spraying holes 9 on the spreading arms 8;

[0070] During the spraying process, the housing 6 is driven by the first linear drive mechanism to move above the sewage pool 1, so that the two spreading arms 8 move along the surface of the sewage to evenly spray the denitrification agent on the surface of the sewage pool 1;

[0071] When the spreading arm 8 moves along the sewage surface, the sealing cover 10 can block the particles floating on the sewage surface to reduce the particles in the spraying range. On the other hand, the sealing cover 10 can eliminate the foam on the sewage surface during the movement, reduce the obstruction to the denitrifying bacteria agent, and thus facilitate the denitrifying bacteria agent to quickly enter the sewage for reaction.

[0072] When the spreading arm 8 moves along the sewage surface, the first scraper 12 is moved along the sealing cover 10 through the second linear drive mechanism, and the first scraper 12 scrapes off the residual foam on the sewage surface in the sealing cover 10, so that the sprayed denitrification bacteria can quickly enter the sewage and fully react with the sewage.

[0073] As an optional embodiment of the pumping mechanism, the pumping mechanism includes:

[0074] A water pump 16, which is fixedly connected to the housing 6, a water inlet pipe of the water pump 16 is connected to an external denitrifying bacteria agent storage tank, and a drain pipe of the water pump 16 is connected to the rotating housing 7;

[0075] The top of the rotating shell 7 is rotatably connected to the rotating cover 17, and the drain pipe of the water pump 16 is fixedly connected to the rotating cover 17;

[0076] Specifically, the denitrifying bacteria agent is pumped into the rotating shell 7 by the water pump 16, and is transported to the two spreading arms 8 by the rotating shell 7, and is sprayed into the sewage through the spraying holes 9 on the spreading arms 8.

[0077] In the specific implementation process, it also includes:

[0078] The driving motor 18 is fixedly connected to the top of the shell 6, and the output shaft of the driving motor 18 is fixedly connected to the rotating shell 7. In the process of spraying the denitrifying bacteria agent, the driving motor 18 drives the rotating shell 7 to rotate, so that the two spreading arms 8 rotate to spray the denitrifying bacteria agent, so as to evenly spray the denitrifying bacteria agent on the surface of the sewage pool 1;

[0079] The output shaft of the driving motor 18 is rotatably connected to the rotating cover 17 .

[0080] As an optional implementation of the first linear drive mechanism, the first linear drive mechanism includes:

[0081] Two guide rails 2, the two guide rails 2 are fixedly connected to the top of the sewage tank 1;

[0082] Two first private service motors 3, the two first private service motors 3 are fixedly connected to the ends of the guide rail 2 at corresponding positions;

[0083] Two first screw rods 4, the two first screw rods 4 are rotatably connected in the guide rails 2 at corresponding positions, and the ends of the first screw rods 4 are fixedly connected to the output shafts of the first private motors 3 at corresponding positions;

[0084] Two connecting frames 5, one end of the two connecting frames 5 is threadedly connected to the first screw rod 4 at the corresponding position, and the other end of the two connecting frames 5 is fixedly connected to the outer side arm of the housing 6;

[0085] Specifically, through the first private service motor 3 and the first screw rod 4, the spreading arm 8 makes a reciprocating straight line along the surface of the sewage pool 1 to evenly spray the denitrification agent on the surface of the sewage pool 1.

[0086] As an optional implementation of the second linear drive mechanism, the second linear drive mechanism includes:

[0087] Two second private service motors 13, the two second private service motors 13 are symmetrically fixedly connected to the ends of the sealing cover 10;

[0088] Two second screw rods 14, the two second screw rods 14 are symmetrically rotatably connected in the sealing cover 10, and the ends of the second screw rods 14 are fixedly connected to the output shaft of the second private motor 13 at the corresponding position;

[0089] Two connecting rods 15 are symmetrically fixedly connected to the top of the first scraper 12, and the top of the connecting rod 15 is threadedly connected to the second screw rod 14;

[0090] Specifically, the first scraper 12 is caused to reciprocate along one end of the inner side of the sealing cover 10 through the second private motor 13 and the second screw rod 14 to eliminate the bubbles in the sealing cover 10 .

[0091] As a further embodiment of the present invention, it also includes:

[0092] Several sealing mechanisms, which are used to seal the spray holes 9 at corresponding positions, include:

[0093] Two sealing plates 19, the two sealing plates 19 are symmetrically slidably connected to the spreading arm 8, and a spring 20 is fixedly connected between the sealing plates 19 and the spreading arm 8;

[0094] The pushing mechanism is arranged at the top of the first scraper 12. When the first scraper 12 moves to scrape off the foam on the sewage surface, the pushing mechanism pushes the sealing plate 19 at the corresponding position to move the sealing plate 19 away from the spraying hole 9, so that the spraying hole 9 at the corresponding position sprays the denitrifier;

[0095] Specifically, by setting a sealing mechanism, during the movement of the first scraper 12, the sealing plate 19 on the path is pushed by the pushing mechanism, so that the two sealing plates 19 on the path are sequentially away from the spray holes 9 in the order of arrangement, and the sealing of the spray holes 9 at the corresponding positions is cancelled, so that the spray holes 9 spray the denitrifier. During the continued movement of the first scraper 12, the pushing mechanism leaves the opened sealing plate 19, and under the elastic action of the spring 20, the sealing plate 19 is reset, and the spray holes 9 are sealed again to prevent the first scraper 12 from re-generating foam at the position after leaving. If the spray holes 9 continue to spray the denitrifier, they are easily hindered by the foam, which reduces the sinking speed of the denitrifier, thereby helping to reduce unnecessary waste of the denitrifier.

[0096] As an optional implementation of the pushing mechanism, the pushing mechanism includes:

[0097] A first push block 21, which is fixedly connected to the bottom end of the sealing plate 19, and both ends of the first push block 21 are provided with first push inclined surfaces;

[0098] Two flip rods 22, the two flip rods 22 are symmetrically connected to the top side wall near the connecting rod 15, and the flip rod 22 has two sections, one of which is a straight rod and the other is an inclined rod;

[0099] The two ends of the flip rod 22 are fixedly connected with a second push block 23, and the end of the second push block 23 is provided with a second push inclined surface matched with the first push inclined surface;

[0100] The rotary drive mechanism is used to drive the flipping rod 22 to flip. When the first scraper 12 moves to the end of the spreading arm 8, the flipping rod 22 is flipped by the rotary drive mechanism, and the straight rod is adjusted to be inclined and the diagonal rod is adjusted to be horizontal;

[0101] Specifically, in the process of the first scraper 12 moving from the end of the sealing cover 10 close to the rotating shell 7 to the other end, the first push block 21 on the path is first pushed by the second push block 23 on the end of the straight rod, so that the first push block 21 on the path drives the sealing plate 19 away from the spray hole 9, so that the spray hole 9 sprays the denitrifying bacteria agent to the position where the foam has been scraped off. After the first scraper 12 moves to the other end of the sealing cover 10, the flip plate is flipped by the rotating drive mechanism, so that the straight rod of the flip rod 22 becomes inclined and the inclined rod becomes horizontal. When the first scraper 12 is reset, the first push block 21 on the path is pushed by the second push block 23 on the end of the inclined rod, so that the sealing plates 19 on the path cancel the sealing of the spray hole 9 in sequence according to the arrangement order.

[0102] The advantage of this pushing mechanism is that the first scraper 12 can make the spray hole 9 at the corresponding position spray the denitrifying bacteria agent after it is away from the bottom of the spray hole 9, so that the first scraper 12 can fully remove the foam in the spraying range. On the one hand, it reduces the interference of the first scraper 12 when the spray hole 9 sprays the denitrifying bacteria agent, and on the other hand, it is helpful to scrape off the foam in the spraying range, reduce the foam content in the spraying range, and make the denitrifying bacteria agent quickly enter the sewage and react with the sewage.

[0106] A second flip block 26, which is coaxially fixed with the flip rod 22, and the second flip block 26 is in a horizontal state;

[0107] A second push rod 27, which is fixedly connected to the side wall near the other end of the sealing cover 10 at a position corresponding to the second flip block 26;

[0108] Specifically, by providing the first flip block 24 and the second flip block 26, when the first scraper 12 moves from the end of the sealing cover 10 close to the rotating shell 7 to the other end, the first flip block 24 is pushed by the first push rod 25, so that the first flip block 24 rotates to a horizontal state, and the second flip block 26 rotates to an inclined state, so that the flip rod 22 rotates;

[0109] During the movement and reset of the first scraper 12 , the second flip block 26 passes through the second push rod 27 , and the flip rod 22 is rotated and reset under the push of the second push rod 27 .

[0110] In a specific implementation process, a damping sleeve 28 is also included. The damping sleeve 28 is sleeved on the rotation axis of the flip rod 22 to increase damping so that the flip rod 22 remains stable after adjustment.

[0112] Two groups of scrapers, the scrapers are symmetrically arranged on both sides of the first scraper 12, each group of scrapers includes two second scrapers 29, and the two second scrapers 29 are symmetrically rotatably connected to the side wall of the first scraper 12;

[0113] A rotary drive assembly, the rotary drive assembly is used to drive the second scraper 29 to flip, so as to further eliminate the foam on the surface of the sewage in the sealing cover 10;

[0114] Specifically, by providing the second scraper 29, during the movement of the first scraper 12, the second scraper 29 is flipped back and forth by rotating the drive assembly to further eliminate the foam on the sewage surface, so that the denitrification bacteria agent can quickly enter the sewage and react with the sewage.

[0115] As an optional embodiment of the rotary drive assembly, the rotary drive assembly includes:

[0116] A gear 30, the gear 30 is coaxially fixed with the top end of the second scraper 29;

[0118] A driving plate 32, the driving plate 32 is fixedly connected to the side wall of the sealing cover 10 near the top;

[0119] A wave groove 33 is provided at the top of the driving plate 32, and the end of the rack 31 is slidably connected in the wave groove 33 through a connecting pin;

[0120] Specifically, by setting the driving plate 32 and the wave groove 33, during the movement of the first scraper 12, the rack 31 moves back and forth along the side wall of the first scraper 12 driven by the wave groove 33. During the back and forth movement of the rack 31, the rack 31 drives the gear 30 to rotate, so that the second scraper 29 flips back and forth to further eliminate the foam on the surface of the sewage, so that the denitrification bacteria agent can quickly enter the sewage and react with the sewage.

[0126] Specifically, during the movement of the first scraper 12 , the floating particles that clog the filter holes 11 are cleaned by the brush plate 34 .

[0127] As a further embodiment of the present invention, the sealing cover 10 is an isosceles trapezoidal cover to increase the spraying range of the spreading arm 8 .

[0128] The working principle of the present invention is as follows: the denitrifying bacteria agent is pumped into the rotating shell 7 by a pumping mechanism, and since the two spreading arms 8 are connected to the rotating shell 7, the denitrifying bacteria agent is sprayed into the sewage through the spraying holes 9 on the spreading arms 8;

[0129] During the spraying process, the housing 6 is driven by the first linear drive mechanism to move above the sewage pool 1, so that the two spreading arms 8 move along the surface of the sewage to evenly spray the denitrification agent on the surface of the sewage pool 1;

[0130] When the spreading arm 8 moves along the sewage surface, the sealing cover 10 can block the particles floating on the sewage surface to reduce the particles in the spraying range. On the other hand, the sealing cover 10 can eliminate the foam on the sewage surface during the movement, reduce the obstruction to the denitrifying bacteria agent, and thus facilitate the denitrifying bacteria agent to quickly enter the sewage for reaction.

[0131] When the spreading arm 8 moves along the sewage surface, the first scraper 12 is moved along the sealing cover 10 through the second linear drive mechanism, and the first scraper 12 scrapes off the residual foam on the sewage surface in the sealing cover 10, so that the sprayed denitrification bacteria can quickly enter the sewage and fully react with the sewage.

[0132] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
