Therefore, the following description should be understood as a broad generalization for those skilled in the art, and not as a limitation on the present application.

[0036] The present application will be described in more detail in the following paragraphs with reference to the drawings. The advantages and features of the present application will be more apparent according to the following description. It should be noted that the drawings are very simplified and all use non-precise proportions, only to facilitate, clear and assist in the purpose of describing the embodiments of the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" in the specification are only for the purpose of clear and easy to describe, and not to limit the scope of the present application, the change or adjustment of the relative relationship, without substantial change of the technical content, is also regarded as the scope of the present application.

[0037] As shown in Figure 1 and Figure 2 The present application proposes a biological liquid treatment waste gas strain screening and domestication device, which comprises: a cylinder body 1; a constant temperature chamber 2, which is arranged below the cylinder body 1, and is provided with a magnetic stirring constant temperature device 3 inside; a culture bottle 5, which is arranged inside the cylinder body 1, and is provided with a magnetic rotor 4 inside, and the magnetic rotor 4 cooperates with the magnetic stirring constant temperature device 3 to move; the magnetic rotor 4 cooperates with the magnetic stirring constant temperature device 3 to realize stirring inside the culture bottle 5, the temperature control and stirring increase the gas-liquid mass transfer efficiency inside the culture bottle 5, and the domestication, screening and culture speed, so as to be suitable for the domestication of liquid biological waste gas purification microorganisms; a breathable bottle plug 6 is arranged at the opening of the culture bottle 5, and an air inlet pipe 7 and an air outlet pipe 8 are arranged on the breathable bottle plug 6; the culture bottle 5 is arranged inside the cylinder body 1, and the space of the culture bottle 5 is limited by the cylinder body 1, so as to reduce the influence of external factors on the domestication and culture of microorganisms inside the culture bottle 5, and reduce the probability of domestication and culture failure.

[0038] Specifically, the purpose of the breathable bottle plug 6 is to provide support for the air inlet pipe 7 and the air outlet pipe 8, and to enable the air in the cylinder body 1 to flow with the air in the culture bottle 5.

[0039] In this example, in order to optimize the magnetic rotor 4 spacing and magnetic field strength, to achieve its stable suspension and optimal stirring effect in the culture flask 5, the height of the magnetic stirring thermostat 3 is adjustable, placed below the culture flask 5, and ensures that the distance between the magnetic stirring thermostat 3 and the magnetic rotor 4 can be accurately adjusted.

[0040] Preferably, the distance between the magnetic stirring thermostat 3 and the culture flask 5 is 4mm, the rotor is suspended at a height of about 1.5mm, and the internal flow of the liquid is uniform without excessive vortex.

[0041] In a specific example, the magnetic rotor 4 is shaped like an ellipsoid with thin ends and a thick middle, which can increase the fluid dynamics, reduce the impact of direct and cylinder bottom or solid particles in the liquid, and reduce the risk of damage.

[0042] As shown in Figure 1 and Figure 3 Specifically, the gas inlet pipe 7 is provided with multiple rows of gas outlet holes at one end immersed in the culture solution. By providing multiple rows of gas outlet holes, the contact area of the incoming gas and the culture solution can be increased, the mixing rate of the gas can be increased, and the efficiency of liquid acclimation, screening and culture can be accelerated.

[0043] In this embodiment, the gas inlet pipe 7 and the gas outlet pipe 8 are both provided with valves, which can avoid the interference of external gas organisms to the environment in the culture flask 5.

[0045] In this example, the gas inlet pipe 7 has three groups, which can realize the entering of multiple acclimation gases into the culture chamber according to the ratio, and realize the acclimation environment of facultative anaerobic microorganisms. The acclimation method of facultative anaerobic microorganisms is: through one group of gas inlet pipes 7, waste gas containing pollutants is introduced into the culture flask 5, and the remaining two groups of gas inlet pipes 7 are introduced into the culture flask 5. Carbon dioxide, nitrogen, and other inert gases dilute the oxygen in the original waste gas to achieve anoxic environment. The gas inlet valve 72 and the gas inlet filter sterilizer 73 are arranged at one end of the third gas inlet pipe penetrating out of the cylinder body 1, which can avoid the influence of external gas organisms entering the culture flask 5 through the gas inlet pipe 7 on liquid acclimation, screening and culture.

[0046] Preferably, the second gas inlet pipe 71 and the second gas outlet pipe 81 are both flexible hoses, so as to guide the gas into and discharge.

[0047] Further, as shown in Figure 4As shown, the third air inlet pipe is provided with an air inlet valve and an air inlet filter sterilizer. The air inlet filter sterilizer 73 comprises a first component 731, a second component 732 and a sterilization filter membrane 733.

The first component 731 and the second component 732 are screwed together from inside to outside. By rotating in the opposite direction, the two components can be disassembled, and the installation and replacement of the sterilization filter membrane 733 can be easily completed.

[0048] It is worth noting that the diameter of the air outlet pipe 8 is greater than the diameter of the air inlet pipe 7 to meet the requirement of discharging the gas after the reaction of the three air inlet pipes 7.

[0049] Further, as shown in Figure 5 The air outlet protector 83 comprises a third component 831, a fourth component 832 and a protection filter membrane 833. The protection filter membrane 833 avoids the reverse entry of other organisms into the exhaust pipe to affect the liquid phase domestication, screening and culture. The protection filter membrane 833 is arranged between the third component 831 and the fourth component 832. The third component 831 and the fourth component 832 are screwed together from inside to outside. By rotating in the opposite direction, the two components can be disassembled, and the installation and replacement of the protection filter membrane 833 can be easily completed.

When the indicator is pink, it represents that the gas in the culture bottle 5 is in an anaerobic state; when the indicator is blue, it represents that the gas in the culture bottle 5 is in an oxygen-rich state; and when only the upper half of the indicator in the oxygen content indicating bottle 13 is pink, it represents that the gas in the culture bottle 5 is in an anoxic (facultative) state. Thus, it can be known that the culture bottle 5 is in an anaerobic, facultative anaerobic, or anaerobic state to domesticate the liquid-phase waste gas treatment microorganisms. In addition, when the static waste gas anaerobic domestication process is carried out, a sufficient amount of oxygen removal bag 14 is placed in the culture chamber to remove the oxygen in the cylinder 1 and to achieve the anaerobic state to domesticate the waste gas treatment microorganisms, thereby increasing the success rate of liquid-phase domestication, screening, and culture.

The transparent glass plate 93 is arranged to not only observe the color change of the oxygen content indicating bottle 13 to know the oxygen content in the cylinder 1, but also directly observe the growth status of the liquid-phase biological waste gas treatment microorganisms.

[0053] Further, the butt flange 11 and the sealing cover flange 92 plate are connected through a first butterfly bolt 10, the first butterfly bolt 10 is provided with a second butterfly bolt 12 adjacent to the side, and the device is connected with the external support body through the second butterfly bolt 12 to facilitate fixation and disassembly in actual use; in addition, the butterfly bolt can be manually assembled and disassembled to reduce the difficulty of disassembling the sealing cover and the cylinder 1, and facilitate the placement and removal of the culture bottle 5 in use.
