[0024] like Figure 1 As shown, a device for biosynthesizing nano-selenium using bacteria includes a housing 1 and a synthesis component 2 disposed in the upper part of the housing 1. The synthesis component 2 is used to ensure uniform stirring of the microbial culture medium and the selenium source solution. It also includes a filter component 3 disposed in the lower part of the housing 1. The filter component 3 is used to perform multiple gentle cleanings on the collected nano-selenium filter cake. A partition 4 is fixedly connected inside the housing 1, which divides the inside of the housing 1 into a closed synthesis chamber 5 and a filter chamber 6. A feed inlet 7 is opened on one side of the synthesis chamber 5, and a sealing cover 8 is connected to the upper end of the feed inlet 7 through a rotating shaft.

[0025] like Figure 2-3 As shown in Figure 4-6, the synthesis component 2 includes a power roller 9, a stirring paddle 10, a lighting module 11, and a temperature control module 12. The power roller 9 is disposed through both ends of the synthesis chamber 5. The extended end of the power roller 9 is connected to the power end of the rotary motor 13. The rotary motor 13 is fixed to the outside of the housing 1. Several stirring paddles 10 are fixed to the middle of the power roller 9. The edges of the stirring paddles are bent. The lighting module 11 includes a photosensitive sensor and a light lamp assembly. The photosensitive sensor is fixed inside the synthesis chamber 5, and the light lamp assembly is fixed to the upper end of the synthesis chamber 5. The temperature control module 12 includes a thermal sensor and a heating plate. A heating chamber is opened on the outside of the synthesis chamber 5. The thermal sensor is fixed inside the synthesis chamber 5, and the heating plate is fixed inside the heating chamber.

[0026] The upper end of the shell 1 is fixed with a support shell, and a microprocessor 14 is installed inside the support shell. A photosensitive sensor, an illumination lamp assembly, a thermal sensor, a heating plate, and a rotary motor 13 are connected to the microprocessor 14 via wires. The photosensitive sensor and the thermal sensor monitor the temperature and illumination of the mixed stock solution entering the synthesis chamber 5 through the feed inlet 7, respectively, and the microprocessor 14 provides feedback on the monitoring data to control the heating plate and illumination lamp assembly to supplement the temperature and illumination intensity. At the same time, the microprocessor 14 controls the rotation of the rotary motor 13, which drives the power roller 9 to rotate, thereby driving the stirring paddle 10 to stir the mixed stock solution. This ensures that the microbial culture medium and selenium source solution are evenly stirred in the reactor, improving the reaction effect without causing excessive mechanical damage to the microorganisms, and ensuring the temperature and illumination conditions for synthesis.

[0027] like Figure 2-3 As shown in Figure 4-5, the filter assembly 3 includes a first filter membrane 15, a second filter membrane 16, an inlet pipe 17, a baffle 18, and a return pipe 19. The first filter membrane 15 is fixed inside the filter chamber 6, and the second filter membrane 16 is fixed inside the filter chamber 6, with the second filter membrane 16 located below the first filter membrane 15. The first filter membrane 15 and the second filter membrane 16 are arc-shaped. The first filter membrane 15 is made of stainless steel mesh, and the second filter membrane 16 is made of nanofiltration membrane. The inlet pipe 17 is fixed to the bottom outside the filter chamber 6, and the filter chamber 6 is connected to the inlet pipe 17. A water pump is provided in the filter chamber 6 near the end of the inlet pipe 17.

A liquid-passing valve is provided between the synthesis chamber 5 and the filtration chamber 6, connecting the synthesis chamber 5 and the filtration chamber 6 respectively. The liquid-passing valve is connected to the microprocessor 14 via a wire. The liquid inlet pipe 17 forms a closed adsorption chamber 1 20. The enclosure 18 and the outside of the liquid inlet pipe 17 form a closed adsorption chamber 21. A through hole is provided at the lower end of the liquid inlet pipe 17, connecting the adsorption chamber 1 20 and the adsorption chamber 21. The adsorption chamber 1 20 and the adsorption chamber 21 are filled with adsorbent. The water pump is connected to the microprocessor 14 via a wire. One end of the return pipe 19 is connected to the adsorption chamber 21, and the other end of the return pipe 19 is connected to the position between the filter membrane 15 and the filter membrane 16 in the filtration chamber 6. When the reaction is completed, the microprocessor... The device 14 controls the liquid inlet valve to connect the synthesis chamber 5 and the filtration chamber 6. The raw materials in the synthesis chamber 5 enter the filtration chamber 6 due to their own gravity. First, coarse filtration is carried out using a stainless steel filter screen to remove large particulate impurities and some microbial cells. Then, an ultrafiltration membrane or nanofiltration membrane is used to further retain the nano-selenium particles, while allowing small molecule culture medium components to pass through, thus achieving the initial separation and collection of nano-selenium. The microprocessor 14 controls the water pump at the bottom of the filtration chamber 6 to suck the filtered solution into the first adsorption chamber 20 and then into the second adsorption chamber 21. The adsorbents filled in the first adsorption chamber 20 and the second adsorption chamber 21 adsorb the impurities and organic matter in the solution. Then, the upper side of the second filter membrane 16 is gently washed multiple times through the return liquid pipe 19 to improve the purity of the filtered material.
