DETAILED DESCRIPTION

[0041] The utility model discloses an embodiment of the utility model will be below-mentioned accompanying drawings Figures 1 to 7 It is obvious that the described embodiments are part of the utility model and not all embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of the utility model.

[0042] A high-efficiency sulfur autotrophic denitrification tank, comprising a rectangular tank body 1, a support frame 3 arranged on the top of the tank body 1. The tank body 1 is used for sulfur autotrophic denitrification nitrogen removal treatment of sewage, and the tank body 1 forms a treatment cavity 2 penetrating through the top. The treatment cavity 2 is divided into a plurality of filler areas in an array, and the plurality of filler areas are consistent in size. Each filler area is provided with a filler assembly 4 and a stirring assembly 5, wherein the filler assembly 4 is used to provide sulfur autotrophic denitrification filler into the tank body 1, and the stirring assembly 5 is used to stir the liquid in the tank body 1.

[0043] In the embodiment, the filler area is provided with four groups, one group including three filler areas, and the three filler areas in one group are distributed equidistantly along the width direction of the tank body 1. The four groups of filler areas are distributed equidistantly along the length direction of the tank body 1, so that the plurality of filler areas are distributed in an array. The support frame 3 is a rectangular plate, and the support frame 3 is distributed along the width direction of the tank body 1. Both ends of the support frame 3 are fixedly connected to the tank body 1. The support frame 3 is provided with four groups corresponding to the filler area, and the four support plates are distributed equidistantly along the length direction of the tank body 1, and the four support plates are one-to-one corresponding to the four groups of filler areas.

[0044] During sewage treatment, sewage is introduced into the treatment cavity 2 of the tank body 1, sulfur autotrophic denitrification filler is provided into the tank body 1 by the filler assembly 4, and stirring is performed by the stirring assembly 5, so that the sulfur autotrophic denitrification filler is dissolved after contacting the sewage, so that the slowly released sulfur source, alkalinity and other reaction substances are converted into nitrogen gas under the action of sulfur autotrophic denitrification bacteria, so as to realize the denitrification process.

[0045] Specifically, the filler assembly 4 comprises a filler fixing plate 41, a filler cylinder 42 connected to the filler fixing plate 41, and a lifting ring 44. The filler fixing plate 41 is a square-shaped cover plate, one side of the filler fixing plate 41 is an inner side, and the other side is an outer side. The filler cylinder 42 is a mesh-shaped cylinder, one end of the filler cylinder 42 is connected to the inner side of the filler fixing plate 41. The support frame 3 is provided with a plate groove 15 corresponding to the filler area, the plate groove 15 and the filler fixing plate 41 are matched with each other, and the filler fixing plate 41 is covered on the plate groove 15. A cylinder groove 16 is provided in the plate groove 15 for the filler cylinder 42 to pass through, the cylinder groove 16 is circular, and the cylinder groove 16 penetrates through the support frame 3. The lifting ring 44 is a semicircular metal ring, which is arranged on the outer side of the filler fixing plate 41 to facilitate driving the filler fixing plate 41 and taking out the filler cylinder 42.

[0046] The filler cylinder 42 is provided with a container 43 for containing sulfur autotrophic denitrification filler, so that by placing the sulfur autotrophic denitrification filler in the container 43, passing the filler cylinder 42 through the cylinder groove 16 to the corresponding filler area of the treatment cavity 2, and covering the filler fixing plate 41 on the plate groove 15, by passing the sewage into the treatment cavity 2 of the pool body 1, and by the sulfur autotrophic denitrification filler in the container 43 contacting the sewage and dissolving, the reaction with the sewage can be carried out, and the denitrification process can be realized. In this embodiment, the container 43 is provided with a plurality of containers 43, and the plurality of containers 43 are divided into multiple groups, the containers 43 in one group are distributed at equal intervals along the axial direction of the filler cylinder 42, and the multiple groups of containers 43 are distributed at equal intervals along the circumferential direction of the filler cylinder 42. Thus, the distribution of sulfur autotrophic denitrification filler in the filler area is relatively uniform, so as to improve the efficiency of the denitrification process and better treat the sewage. In addition, since the filler cylinder 42 itself has a certain weight, it is not necessary to set a counterweight, and the container 43 can sink into the reaction cavity by the gravity of the filler cylinder 42 itself to facilitate contact and reaction with the sewage, and compared with the original design, the filler cylinder 42 effectively prevents the containers 43 from winding with each other.

[0047] The container 43 comprises a spherical container body 431, an upper cover 432, an ear part 433 and a buckle 434. The container body 431 is a spherical bottle. When filling, the sulfur autotrophic denitrification filler is filled into the container body 431 through the bottle opening of the container body 431. The upper cover 432 is used to open or close the bottle opening of the container body 431. The upper cover 432 is detachably connected to the container body 431. The upper cover 432 is provided with external threads 6. The bottle opening of the container body 431 is provided with internal threads 7. The external threads 6 and the internal threads 7 are threadedly matched with each other. When the external threads 6 and the internal threads 7 are matched with each other, the upper cover 432 blocks the bottle opening of the container body 431. Thus, the bottle opening of the container body 431 is opened or closed through the upper cover 432. The sulfur autotrophic denitrification filler can be conveniently filled. It should be noted that in the embodiment, the sulfur autotrophic denitrification filler is mixed by sulfur particles and polyvinyl alcohol macromolecular particles at a volume ratio of 1:1. The particle size of the particles is about 6 mm. The filling rate of the autotrophic denitrification filler in the container body 431 is 65% to 70%. The filling rate is ensured to be in the range of 65% to 70% to ensure that the sulfur autotrophic denitrification filler is effectively dissolved and functions.

[0048] The ear part 433 is integrally formed with the container body 431. The ear part 433 is close to the bottle opening of the container body 431. The buckle 434 is a mountaineering buckle. The mountaineering buckle is a mature technology in the prior art. Details are not described herein. The mountaineering buckle has the characteristics of quick connection and release. The mountaineering buckle is beneficial to improve the efficiency and convenience of connection. The buckle 434 penetrates the grid rib of the filler cylinder 42 and the ear part 433 and is buckled tightly. Thus, the container body 431 is connected with the filler cylinder 42. The container body 431 is separated from the filler cylinder 42 by loosening the buckle 434.

[0049] A plurality of communication holes (not shown in the figure) are arranged on the side wall of the container body 431. The communication holes penetrate the inner and outer surfaces of the container body 431. A plurality of communication holes are arranged on the container body 431. The distance between adjacent two communication holes is the same. The aperture of the communication hole is 2 mm to 4 mm. The porosity of the communication holes arranged on a single container body 431 is in the range of 60% to 90%. In the embodiment, the aperture is preferably 2.8 mm. The porosity is 80%. The porosity is beneficial to ensure the flowability of the sewage and the container body 431 and prevent the large undissolved sulfur autotrophic denitrification filler particles from falling out. Thus, when the sewage is treated, the sewage enters the container body 431 through the communication holes and contacts the sulfur autotrophic denitrification filler in the container body 431. The sulfur autotrophic denitrification filler is continuously dissolved. Thus, the concentration value of the sulfur autotrophic denitrification filler dissolved in the sewage is ensured.

[0050] The stirring end of the stirring assembly 5 extends into the filler barrel 42, that is, the filler barrel 42 surrounds the stirring end of the stirring assembly 5, so that a plurality of container bodies 431 are distributed around the stirring assembly 5. When the stirring speed of the stirring assembly 5 is changed, the water flow speed around the stirring end of the stirring assembly 5 is changed, the container body 431 is driven to shake to different degrees, and the relative motion between the sulfur autotrophic denitrification filler molecules and water molecules is increased or decreased, thereby effectively changing the dissolution speed of the sulfur autotrophic denitrification filler, adjusting the concentration value of the sulfur autotrophic denitrification filler dissolved in the sewage, and thereby coping with sewage with different nitrogen contents and improving the sewage treatment efficiency.

[0051] In use, the sulfur autotrophic denitrification filler is loaded from the bottle opening of the container body 431, the outer thread 6 is threadedly connected with the inner thread 7 by driving the upper cover 432, the upper cover 432 seals the bottle opening of the container body 431, and finally the container body 431 is connected with the filler barrel 42 through the buckle 434, that is, the container body 431 is connected with the filler barrel 42. After the container bodies 431 are connected with the filler barrel 42 one by one, the filler barrel 42 is inserted into the processing cavity 2 corresponding to the filler area through the barrel groove 16, the filler fixing plate 41 is covered on the plate groove 15, and the sewage is introduced into the processing cavity 2 of the pool body 1, so that the sewage enters the container body 431 through the communication hole and contacts with the sulfur autotrophic denitrification filler in the container body 431, so that the sulfur autotrophic denitrification filler is dissolved. Through the stirring assembly 5, the sulfur sewage flow is accelerated, and the denitrification nitrogen removal work is also accelerated, and the sewage treatment efficiency is improved. At the same time, according to the required content of the sulfur autotrophic denitrification filler, the stirring speed of the stirring assembly 5 is changed, the concentration value of the sulfur autotrophic denitrification filler dissolved in the sewage is adjusted, thereby coping with sewage with different nitrogen contents and further improving the sewage treatment efficiency.

[0052] Specifically, the stirring assembly 5 comprises a rotating shaft 51 arranged in the bottom of the pool body 1 and stirring blades 52 arranged on the rotating shaft 51. The rotating shaft 51 is distributed along the axial direction of the filler cylinder 42 and is in line with the central axis of the filler cylinder 42. One end of the rotating shaft 51 extends into the filler cylinder 42, and the filler cylinder 42 is arranged around the rotating shaft 51. The stirring blades 52 are arranged on the end of the rotating shaft 51 extending into the filler cylinder 42. The stirring blades 52 are arranged in multiple groups. Each group comprises two stirring blades 52. The two stirring blades 52 in each group are distributed at equal intervals along the circumferential direction of the rotating shaft 51, i.e., the two stirring blades 52 in each group are opposite to each other. The multiple groups of stirring blades 52 are distributed at equal intervals along the length direction of the rotating shaft 51. The end of the rotating shaft 51 extending into the filler cylinder 42 and the multiple groups of stirring blades form the stirring end of the stirring assembly 5. Thus, by driving the rotating shaft 51 to rotate, the stirring blades 52 can be driven to rotate, the flow of sewage around the filler cylinder 42 can be effectively changed, the container 43 can be shaken to different degrees, and the relative movement between the sulfur autotrophic denitrification filler molecules and water molecules can be enhanced or reduced, thereby effectively changing the dissolution speed of the sulfur autotrophic denitrification filler, adjusting the concentration value of the sulfur autotrophic denitrification filler dissolved in the sewage, and coping with sewage with different nitrogen contents to improve the sewage treatment efficiency. The multiple groups of stirring blades 52 are beneficial to improving the stirring efficiency.

[0053] In addition, in order to conveniently drive the stirring assembly 5 to rotate, the pool body 1 is also provided with a driving assembly for synchronously driving the stirring assembly 5 of one group of filler regions to rotate. Specifically, the driving assembly comprises a driving member 8 arranged on the pool body 1, a first transmission wheel 9 sleeved on the driving end of the driving member 8, and a second transmission wheel 10.

[0054] The driving member 8 is a driving motor. The rotating shaft 51 located in the middle of one group of filler regions is connected to the driving end of the driving member 8. One rotating shaft 51 adjacent to the rotating shaft 51 located in the middle of one group of filler regions is sleeved with a third transmission wheel 11. The first transmission belt 12 is arranged between the third transmission wheel 11 and the first transmission wheel 9 and is wrapped around the third transmission wheel 11 and the first transmission wheel 9. The transmission structure of the transmission wheel and the transmission belt is a very mature technology in the prior art, and thus will not be described in detail. Similarly, the other rotating shaft 51 adjacent to the rotating shaft 51 located in the middle of one group of filler regions is sleeved with a fourth transmission wheel 13. The second transmission belt 14 is arranged between the fourth transmission wheel 13 and the second transmission wheel 10 and is wrapped around the fourth transmission wheel 13 and the second transmission wheel 10. Thus, by driving the driving member 8, the rotating shaft 51 in one group of filler regions can be synchronously driven to rotate, thereby reducing energy consumption. When the driving speed is changed, the rotating speed of the rotating shaft 51 in one group of filler regions can be synchronously changed by changing the driving speed of the driving member 8.

[0055] The implementation principle of the present application is as follows: in use, the sulfur autotrophic denitrification filler is loaded from the bottle opening of the container body 431, the upper cover 432 is driven to make the external thread 6 and the internal thread 7 threadedly matched with each other, the upper cover 432 is used to block the bottle opening of the container body 431, finally the container body 431 is connected with the filler cylinder 42 through the buckle 434, and the container device 43 can be connected to the filler cylinder 42. After the container device 43 is connected to the filler cylinder 42 one by one, the filler cylinder 42 is passed through the cylinder groove 16 to the corresponding filler area of the treatment cavity 2, the filler fixing plate 41 is covered on the plate groove 15, and the sewage is passed into the treatment cavity 2 of the pool body 1, so that the sewage enters the container body 431 through the communication hole and contacts the sulfur autotrophic denitrification filler in the container body 431, the sulfur autotrophic denitrification filler is dissolved, the slowly released sulfur source, alkalinity and other reaction substances are converted into nitrogen gas under the action of the sulfur autotrophic denitrification bacteria, and the denitrification process is realized.

[0056] The driving member 8 is used to synchronously drive the rotating shafts 51 in a group of filler areas to rotate, change the flow of the sewage, accelerate the speed of the sewage treatment, and improve the sewage treatment efficiency. According to the required content of the sulfur autotrophic denitrification filler, the stirring speed of the stirring assembly 5 is changed, the flow speed of water around the stirring end of the stirring assembly 5 is changed, the container body 431 is driven to shake at different speeds, and the relative movement between the sulfur autotrophic denitrification filler molecules and water molecules is enhanced or reduced, so that the dissolution speed of the sulfur autotrophic denitrification filler is effectively changed, the concentration value of the sulfur autotrophic denitrification filler dissolved in the sewage is adjusted, different nitrogen content of the sewage is dealt with, and the sewage treatment efficiency is further improved.
