  • Patent number: 12178196
    Abstract: The present disclosure provides a recirculation aquaculture system and method. The system includes a fish pond and a fiber turntable filtering system. The fiber turntable filtering system can implement can remove large particles in aquaculture water and regularly harvest microalgae, water quality after treatment reaches a fishery aquaculture standard, and 97% of the aquaculture water can be directly recycled. In the present disclosure, during in-situ culture of microalgae and fish, microalgae can convert CO2 exhaled by fish and nutrients such as nitrogen and phosphorus in the aquaculture water into substances of algae cells, such as proteins, polysaccharides, vitamins, and lipids, and release oxygen, so as to quickly improve quality of the aquaculture water; in-situ culture of the microalgae and the fish gives play to the advantages of high photosynthetic efficiency of the microalgae, and the fast-growing microalgae provide a suitable growth environment for the fish.

  • Publication number: 20240264109
    Abstract: A preparation method and use of a BiOX/N-doped biochar nanocomposite, where X is I or Br is provided. The preparation method includes the following steps: step 1: preparation of an N-doped biochar; step 2: preparation of an acidified N-doped biochar; and step 3: preparation of the BiOX/N-doped biochar nanocomposite. In the present disclosure, a discarded crayfish shell, crab shell, or tofu residue is used as a raw material to prepare the BiOX/N-doped biochar nanocomposite, to realize the transformation of a renewable biological resource from waste into treasure. A photoelectric sensor is constructed based on the BiOX/N-doped biochar nanocomposite that can realize the detection of adenosine triphosphate (ATP) or Escherichia coli (E. coli).

  • Publication number: 20240224958
    Abstract: An industrialized fish and algae farming system with recirculating water and method are provided, and the system includes a fish and algae farming system, a fiber rotary disc filter system, and a magnetic loading flocculation system. In accordance with the fish and algae farming system, the aquaculture of fish and algae in the same space is achieved, the algae can transform CO2 exhaled by fish and nutrients, polysaccharides, vitamins and lipids, and then release oxygen to rapidly improve the aquaculture water quality. The fiber rotary disc filter system and the magnetic loading flocculation system can effectively remove suspended particles, grease, algae, bacteria, viruses and the like in aquaculture sewage, thus achieving the deep purification of the aquaculture sewage. The purified water quality reaches the aquaculture standards in fishery and can be directly recycled, and the whole system has no sewage discharge.
