[0001] The present application relates to the technical field of microbial cultivation, and in particular to a microbial expansion and cultivation device. Background Art

[0002] In the field of water restoration such as ponds, rivers or lakes, more and more microorganisms are used to treat pollution. Due to the large demand for microorganisms, it is often expensive to purchase finished strains directly from the market. Therefore, expanding strains through microbial expansion devices at the project site has become an effective way to reduce water treatment costs.

[0003] The current microbial expansion device usually adopts a batch culture method, which is to put bacteria and nutrients into the microbial culture chamber, cultivate the bacteria by oxygenation and stirring, and only feed but not discharge during the culture process, and discharge once after the culture is completed. Although this culture method is simple, it has low culture efficiency and cannot be carried out continuously. Utility Model Content

[0018] This microbial expansion culture device adopts the microbial culture technology of the mud-film symbiosis method. First, the reaction raw water and nutrients are respectively input into the microbial culture chamber through the feed inlet and the chemical addition port to culture the primary microbial flora. In the initial stage, microorganisms are attached to the film on the filler unit to ensure the stability of the microbial strains. As the microbial strains grow and spread continuously in the microbial culture chamber, a large number of microbial flora are suspended in the mixed liquid in the microbial culture chamber. During the culture process, a part of the reacted water body is discharged through the discharge port to the microbial receiving point outside the microbial culture chamber to expand the microorganisms. After each discharge of the mixed liquid, the suspended microbial concentration in the microbial culture chamber drops significantly.

Preferably, the microbial culture expansion device 10 can adopt an integrated modular design to reduce the floor area of the microbial culture expansion device 10 while facilitating the later maintenance of the microbial culture expansion device 10.

[0032] As Figure 2As shown, the microbial expansion culture device 10 includes a microbial culture chamber 100, a packing unit 200, and an aeration unit 300. A feed inlet 110, a chemical addition port 120, and a discharge port 130 are provided on the side wall of the microbial culture chamber 100. The feed inlet 110 and the chemical addition port 120 are respectively used for supplying reaction raw water and nutrients to enter the microbial culture chamber 100; the discharge port 130 is used for discharging the water body after the reaction in the microbial culture chamber 100 to the outside; the packing unit 200 is arranged in the microbial culture chamber 100, and the packing unit 200 is used for the attachment and growth of microorganisms; the aeration unit 300 is arranged in the microbial culture chamber 100 and is located at the bottom of the packing unit 200; the aeration unit 300 is used to provide oxygen for the reproduction of microorganisms in the microbial culture chamber 100.

[0033] The microbial expansion culture device 10 adopts the mud-film symbiosis method of microbial culture technology. First, the reaction raw water and nutrients are respectively input into the microbial culture chamber 100 through the feed inlet 110 and the chemical addition port 120 to culture the primary microbial flora. In the initial stage, microorganisms are attached to the packing unit 200 to ensure the stability of the microbial strains. As the microbial strains grow and spread continuously in the microbial culture chamber 100, a large number of microbial flora are suspended in the mixed liquid in the microbial culture chamber 100. During the culture process, a part of the water body after the reaction is discharged through the discharge port 130 to the microbial receiving point outside the microbial culture chamber 100 to expand the microorganisms. After each discharge of the mixed liquid, the concentration of suspended microorganisms in the microbial culture chamber 100 drops significantly. At this time, through the microorganisms highly enriched on the packing biofilm, the microorganisms are continuously expanded and cultured into the mixed liquid to prevent excessive drainage from causing excessive loss of microorganisms and losing the expansion culture effect. In addition, an aeration unit 300 is arranged in the microbial culture chamber 100 to ensure that the microbial culture chamber 100 is in an aerobic environment, prompting the microorganisms to always be in a highly efficient reproduction state, achieving the purpose of continuous culture, and thus realizing the continuous and efficient microbial amplification. In this solution, the aeration unit 300 is installed at the bottom of the packing unit 200 to ensure the relative positions of the packing unit 200 and the aeration unit 300, and avoid sludge deposition in the packing unit 200. In addition, the microbial expansion culture device 10 adopts the mud-film symbiosis method of microbial culture technology. After the initial inoculation is successful and the parameters are set, it can operate fully automatically, greatly reducing the later manual maintenance cost of the microbial expansion culture device 10.

[0034] The microbial culture chamber 100 can be cube-shaped or cylindrical. Preferably, the microbial culture chamber 100 is made of 316 stainless steel, and 316 stainless steel has good anti-corrosion performance and can adapt to harsh water quality environments such as fresh water and seawater.

[0035] Specifically, the feed inlet 110 and the chemical addition port 120 are arranged on the same side of the microbial culture chamber 100, and the feed inlet 110 and the discharge outlet 130 are respectively arranged on opposite sides of the microbial culture chamber 100. Optionally, the microbial expansion device 10 further includes a water injection pump, which is connected to the feed inlet 110 and is used to pump the reaction raw water into the microbial culture chamber 100 through the feed inlet 110. Further, the discharge outlet 130 discharges water in a way of overflow. Specifically, the reaction raw water is pumped into the microbial culture chamber 100 through the water injection pump, and the water level in the microbial culture chamber 100 continuously rises. When the water level in the microbial culture chamber 100 rises to the height where the discharge outlet 130 is located, the discharge outlet 130 overflows with water.

[0036] Further, a sludge discharge port 150 is provided at the bottom of the microbial culture chamber 100 to facilitate the timely discharge of the sludge formed in the microbial culture chamber 100. At the same time, the sludge discharge port 150 is also used as a drain port to drain the mixed liquid in the microbial culture chamber 100. Further, a sludge discharge valve 152 is provided on the sludge discharge port 150, and the sludge discharge valve 152 is used to control the opening and closing of the sludge discharge port 150.

Specifically, water and nutrients can be automatically added to the microorganism culture chamber 100 according to the feedback of the detection sensor. When the concentration of microorganisms is high, water intake is started and the mixed liquid is discharged by overflow. When the concentration of microorganisms is below a certain level, water intake is stopped for microorganism cultivation. Meanwhile, during microorganism cultivation, nutrients are regularly added to the microorganism culture chamber 100 to maintain the growth and reproduction of microorganisms.
