Description

Technical Field

[0001] The invention relates to the technical field of aquaculture wastewater treatment, and in particular to a method for treating aquaculture pond wastewater. Background Art

[0002] At present, in aquaculture ponds, with the use of water bodies and the increase of breeding density, various pollutants will be produced. Feed that is not consumed by aquatic animals is deposited at the bottom of the water to form feed residues, causing water quality to deteriorate. The excrement of aquatic animals is rich in nutrients, especially nitrogen and phosphorus, which can easily lead to eutrophication of water bodies. Ammonia nitrogen is generated during the decomposition process of aquatic animal excrement. Excessive concentration of ammonia nitrogen can be toxic to aquatic organisms. The accumulation of organic matter in the bottom mud may cause problems such as hypoxia, which in turn affects water quality and breeding results. Strengthening management and water quality monitoring is essential for sustainable breeding.

[0003] A Chinese invention patent with publication number CN114853263A discloses a method for treating freshwater aquaculture wastewater. By adding algaecides and purifiers, algae, heavy metal elements, organic elements such as nitrogen and phosphorus can be removed to purify the water quality. By adding microorganisms such as ammonia-forming bacteria, nitrifying bacteria, denitrifying bacteria, nitrogen-fixing bacteria and cellulose-decomposing bacteria, carbon-based, phosphorus-based, and sulfur-based pollutants, as well as proteins, polysaccharides and water-soluble organic matter are further decomposed, thereby increasing the water purification effect.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: adding chemicals inside the breeding pond will have an adverse effect on the breeding pond, and the input of multiple chemical agents into the breeding pond will not only affect the aquatic products, but also cause harm to the water quality and internal environment of the breeding pond. Summary of the invention

[0005] The invention provides a method for treating aquaculture pond wastewater, which has the advantages of recycling water resources, reducing chemical elements in aquaculture ponds and recycling wastes, and solves the problem of adding chemicals inside aquaculture ponds, which will have an adverse effect on aquaculture ponds.
