Technical Field

[0001] This utility model relates to the technical field of nitrifying bacteria cultivation devices, specifically an oxygen supplementation mechanism and a nitrifying bacteria cultivation device containing the mechanism. Background Technology

[0002] The core function of the wastewater treatment nitrifying bacteria cultivation device is to provide a suitable growth and reproduction environment for nitrifying bacteria (including ammonia oxidizing bacteria and nitrite oxidizing bacteria). By regulating key conditions such as dissolved oxygen, pH value, and temperature, it promotes their rapid enrichment and acclimatization in an environment containing ammonia nitrogen substrate, thereby cultivating a highly active nitrifying bacteria community. The nitrifying bacteria community is then added to the wastewater for purification treatment.

[0003] Existing devices mostly use fixed aeration discs or unidirectional aeration, resulting in large and unevenly distributed oxygen bubbles, low dissolved oxygen efficiency, and a tendency to create localized hypoxic areas. Furthermore, they often use electric heating rods for direct heating, which can easily lead to excessively high local temperatures and uneven temperature distribution, making it difficult to maintain a suitable temperature range of 25-35℃.

[0004] Based on this, an oxygen supplementation mechanism and a nitrifying bacteria culture device containing the mechanism are provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] First embodiment: In one embodiment, such as Figures 1-2 As shown, an oxygen supplementation mechanism includes a culture tank 1. An oxygen supplementation component 6 is provided at the bottom of the culture tank 1. The oxygen supplementation component 6 includes multiple fixed tubes 61, which are all fixedly installed at the bottom of the culture tank 1. Rotating components 62 are rotatably installed on the top of each of the multiple fixed tubes 61. Spray nozzles 63 are equidistantly arranged in a ring around the outside of each of the multiple rotating components 62. An oxygen supplementation pipe 64 is provided at the bottom of the culture tank 1 and is connected to the multiple fixed tubes 61.

[0024] In this embodiment, the culture tank 1 is equipped with an oxygen content sensor and a temperature sensor. When the oxygen content is insufficient, the oxygen supply pump operates to introduce oxygen into the oxygen supply pipe 64. The oxygen then enters the rotating component 62 through the fixed pipe 61, and is finally discharged through the air outlet of the rotating component 62 and the nozzle 63. Since the nozzle 63 is set at an angle, and due to the action and reaction forces, the rotating component 62 rotates, thereby driving the liquid inside the culture tank 1 to stir, so that the oxygen dissolves quickly in the liquid and improves the oxygen supply efficiency.

[0025] Second embodiment: In one embodiment, such as Figures 1-4 As shown, a nitrifying bacteria cultivation device includes a top cover 2 and an oxygen supplementation mechanism as described in the first embodiment. The top cover 2 is disposed on the top of the cultivation tank 1, and a stirring mechanism 4 is disposed on the top of the top cover 2. A feeding mechanism 7 is disposed on one side of the cultivation tank 1, and a temperature control mechanism 11 is disposed on the other side of the cultivation tank 1. A sampling component is disposed on the outside of the cultivation tank 1.

[0026] In this embodiment, the nutrients required for nitrifying bacteria cultivation can be added to the inside of the culture tank 1 through the feeding mechanism 7. The culture tank 1 is heated by water bath through the temperature control mechanism 11, so that the internal temperature of the culture tank 1 is maintained at 25-35 degrees Celsius. The stirring mechanism 4 ensures that the liquid temperature inside the culture tank 1 is uniform and that the added nutrients are evenly mixed with the liquid, thereby improving the nitrifying bacteria cultivation efficiency.

[0027] In one embodiment, such as Figure 1 and Figure 4 As shown, the feeding mechanism 7 includes a feeding pipe 71, which is fixedly connected to the outer wall of the culture tank 1. A feeding hopper 72 is fixedly connected to the top of the feeding pipe 71. An impeller 73 is rotatably mounted inside the feeding pipe 71 via a bearing. A second motor 74 is provided on one side of the feeding pipe 71, and the impeller 73 is driven by the second motor 74. An air pump 75 is fixedly mounted outside the feeding pipe 71. The output end of the air pump 75 passes through the feeding pipe 71 and is connected to an air bag 76. When nutrients need to be added, the air pump 75 operates to extract the air from inside the air bag 76, and the nutrients are placed inside the feeding hopper 72. The second motor 74 drives the impeller 73 to rotate, and the rotation of the impeller 73 transports the nutrients into the culture tank 1, preventing the feeding pipe 71 from becoming blocked. After the nutrients are added, the air pump 75 injects air into the air bag 76, causing the air bag 76 to expand and block the feeding pipe 71.

[0028] In one embodiment, such as Figure 1 and Figure 3As shown, the stirring mechanism 4 includes a first motor 41, which is fixedly installed on the top of the top cover 2. The output end of the first motor 41 passes through the top cover 2 and is connected to a drive shaft 42. The external key of the drive shaft 42 is connected to a stirring blade 43, which is located inside the culture tank 1. The first motor 41 drives the drive shaft 42 to rotate, which in turn drives the stirring blade 43 to rotate, thus stirring the liquid inside the culture tank 1.

[0029] In one embodiment, such as Figure 1 and Figure 3 As shown, the temperature control mechanism 11 includes an inlet pipe 111 and an outlet pipe 112. The inlet pipe 111 and the outlet pipe 112 are both fixedly connected to the outer wall of the culture tank 1. The inner wall of the culture tank 1 is provided with a water tank 113. The inlet pipe 111 and the outlet pipe 112 are both connected to the water tank 113. Hot water at 35 degrees Celsius is injected into the water tank 113 through the inlet pipe 111. After the hot water fills the water tank 113, it is discharged through the outlet pipe 112, thereby heating the liquid inside the culture tank 1 in a water bath.

[0030] In one embodiment, such as Figure 3 As shown, the sampling assembly includes a sampling tube 8, which is fixedly connected to the outer wall of the incubator 1. A sampling valve 9 is provided at the top of the sampling tube 8, and a sampling bottle 10 is threadedly connected to the bottom of the sampling tube 8. After the nitrifying bacteria have been cultured for a period of time, the sampling valve 9 is opened, and the liquid enters the interior of the sampling bottle 10 through the sampling tube 8. Then the sampling valve 9 is closed, and the sampling bottle 10 is rotated to test the sampled liquid to determine whether the concentration of nitrifying bacteria meets the standard. If the standard is met, the liquid is introduced into the wastewater treatment device through the discharge pipe 12, where it is treated by the nitrifying bacteria and the wastewater.

[0031] In one embodiment, such as Figure 1 and Figure 3 As shown, the bottom of the culture tank 1 is provided with three support legs 3 arranged in a ring at equal intervals. The top of the top cover 2 is connected to a connecting pipe 5 on one side. The culture tank 1 is provided with a discharge pipe 12 on one side. The gas inside the culture tank 1 is discharged through the connecting pipe 5 to maintain the gas pressure inside the culture tank 1.

[0032] The above embodiments disclose an oxygen supplementation mechanism and a nitrifying bacteria culture device containing the mechanism. The culture tank 1 is equipped with an oxygen content sensor and a temperature sensor. When the oxygen content is insufficient, the oxygen supply pump operates to introduce oxygen into the oxygen supplementation pipe 64. The oxygen then enters the rotating component 62 through the fixed pipe 61 and is finally discharged through the air outlet and nozzle 63 of the rotating component 62. Since the nozzle 63 is set at an angle and has action and reaction forces, the rotating component 62 rotates, thereby driving the liquid inside the culture tank 1 to stir, so that the oxygen dissolves quickly in the liquid and improves the oxygen supplementation efficiency.

[0033] Nutrients required for nitrifying bacteria cultivation can be added to the inside of the culture tank 1 through the feeding mechanism 7. The culture tank 1 is heated by a water bath through the temperature control mechanism 11, so that the internal temperature of the culture tank 1 is maintained at 25-35 degrees Celsius. The stirring mechanism 4 works to ensure that the liquid temperature inside the culture tank 1 is uniform and that the added nutrients are evenly mixed with the liquid, thereby improving the nitrifying bacteria cultivation efficiency. After the nitrifying bacteria have been cultivated for a period of time, the sampling valve 9 is opened, and the liquid enters the inside of the sampling bottle 10 through the sampling tube 8. Then the sampling valve 9 is closed, and the sampling bottle 10 is rotated to test the sampled liquid to determine whether the nitrifying bacteria concentration meets the standard. If the standard is met, the liquid is introduced into the wastewater treatment device through the discharge pipe 12, where it is treated by the nitrifying bacteria and the wastewater.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
