[0002] Aquaculture ponds are home to aquatic products such as fish, shrimp, and shellfish. Intensive aquaculture is the primary method of aquaculture. During the aquaculture process, large amounts of excrement and food scraps settle to the bottom of the pond. These sediments are further broken down by bacteria, producing ammonia nitrogen and nitrite nitrogen, which are highly harmful to the farmed animals. This causes severe pollution of the aquaculture water environment and poses significant risks to aquaculture production. Traditional methods for reducing sediment risks include manual pond cleaning, chemical bottom modification, and the application of microbial agents. Traditional pond bottom modification methods often require extensive construction, high chemical and microbiological expertise, and the deployment of high-powered aerators to drive water flow and circulation, resulting in relatively high costs. Therefore, a solution is urgently needed.

Compared with the traditional method of improving the bottom sediment of aquaculture ponds, it can be colonized in the bottom sediment and has the advantages of small construction volume, low technical requirements, and easy use. The microbial colonization rod adopts a method combining chemical oxygenation, physical adsorption and microbial purification to achieve the goal of effectively reducing bottom sediment pollutants.

[0025] Example
[0026] See also Figure 1-3 As shown:
[0027] The utility model provides a slow-release oxygenation type microbial colonization rod for improving bottom mud sediments, comprising: a microbial colonization layer 11, a buffer layer 21, a slow-release oxygenation layer 31 and a connecting component.
[0028] The slow-release oxygenation layer 31 is an oxygenation layer that slowly releases oxygen for oxygen reaction in water. The slow-release oxygenation layer 31 includes an oxygenator, a binder, and a slow-release agent. The oxygenator is calcium oxide and magnesium peroxide; the binder is straw-based biochar and zeolite; and the slow-release agent is chitosan and sodium alginate.
[0029] The buffer layer 21 is disposed outside the slow-release oxygenation layer 31 and is used to absorb byproducts of the oxygen reaction in the slow-release oxygenation layer 31. The buffer layer 21 includes straw-based biochar and zeolite.
[0030] The microbial colonization layer 11 is arranged outside the buffer layer 21, and is used to carry microorganisms and provide a place for the growth and reproduction of microorganisms. The microbial colonization layer 11 includes microbial powder, straw-made biochar and zeolite.
[0031] The connecting components are respectively arranged outside the microbial colonization layer 11, the buffer layer 21 and the slow-release oxygenation layer 31, and are provided with a cavity for providing a place for the microbial colonization layer 11, the buffer layer 21 and the slow-release oxygenation layer 31 to accommodate and react.
[0032] The connection assembly mainly consists of a first double-layer tube 10 , a second double-layer tube 20 and a third double-layer tube 30 .
[0033] The first double-layer tube 10 is formed by two circular tubes nested together, with a gap between them. A connecting plate 41 is provided in the gap, connecting the two tubes. The first double-layer tube 10, the second double-layer tube 20, and the third double-layer tube 30 all have the same structure, differing only in diameter, which is arranged in descending order.
[0034] In a specific application, the first double-layer tube 10 is placed outside the second double-layer tube 20, and the microbial colonization layer 11 is filled between the first double-layer tube 10 and the second double-layer tube 20. The second double-layer tube 20 is placed outside the third double-layer tube 30, and the buffer layer 21 is filled between the second double-layer tube 20 and the third double-layer tube 30. The adsorption slow-release oxygenation layer 31 is filled in the third double-layer tube 30.
[0035] Through holes 13 are provided on the first double-layer tube 10 , the second double-layer tube 20 and the third double-layer tube 30 , so that the first double-layer tube 10 , the second double-layer tube 20 and the third double-layer tube 30 are connected to each other.
[0036] The diameters of the through holes 13 located on the first double-layer tube 10 , the second double-layer tube 20 and the third double-layer tube 30 are decreasing in sequence, that is, the diameter of the through hole 13 on the third double-layer tube 30 is the smallest.
[0037] The through holes 13 on the first double-layer tube 10 , the second double-layer tube 20 and the third double-layer tube 30 are staggered, which can slow down the reaction speed of the microbial colonization layer 11 , the buffer layer 21 and the slow-release oxygenation layer 31 .
[0038] The end caps 12 are provided at both ends of the first double-layer tube 10 and are threadedly connected to both ends of the first double-layer tube 10 , thereby facilitating the disassembly and cleaning of the entire connection assembly.
[0039] During specific use, the slow-release oxygen-enhancing microbial colonization rods are colonized in the bottom mud sediment of the aquaculture pond. The colonization rods can be completely colonized in the bottom mud or partially exposed above the bottom mud layer. Depending on the size of the aquaculture pond, multiple colonization rods can be set in it at a certain density.
[0040] When the oxygenator reacts with oxygen, the oxygen can provide the microbial carrier layer with the oxygen required for the microbial metabolic process through the buffer layer 21. The buffer layer 21 can adsorb the reaction by-products of the oxygenator to keep the pH of the microbial carrier layer within an appropriate range. Under appropriate growth conditions, the microorganisms in the microbial carrier layer proliferate in large numbers and carry out metabolic activities. In this way, the decomposition of organic matter in the bottom sediment of the aquaculture pond and the absorption and conversion of substances such as nitrogen and phosphorus are achieved, thereby achieving the purpose of bottom sediment improvement.
[0041] After each slow-release oxygen-enhancing microbial colonization stick for sediment improvement has worked for a period of time or after the end of the breeding period, it is taken out from the breeding pond. It is rich in nutrients such as nitrogen and phosphorus. After collection and treatment, it can be used as high-quality fertilizer to provide nitrogen fertilizer and phosphorus fertilizer to crops.

If the specific posture changes, the directional indications will also change accordingly. In addition, if the embodiments of the present invention involve descriptions such as "first" and "second", then such descriptions such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.
