Description

Technical Field

[0001] The present invention relates to the field of aquaculture tail water treatment, and in particular to an aquaculture tail water treatment system and method based on artificial wetland purification technology. Background Art

[0002] Aquaculture tailwater refers to wastewater generated during the aquaculture process, which contains organic substances such as feces, feed residues, metabolites of organisms discharged during the production of aquatic animals such as fish and shrimp, and may contain pollutants such as residual drugs and heavy metal ions. Therefore, it is necessary to reasonably set up the aquaculture environment, feed reasonably, and regularly manage and monitor the aquaculture water body during the aquaculture process to ensure the quality of the aquatic environment and the health of the aquaculture organisms. At the same time, it is also necessary to treat the aquaculture wastewater to reduce the pollution to the aquatic environment. In the existing technology for treating aquaculture tailwater, it is usually necessary to use a variety of treatment equipment, such as filters, oxidation ponds, cyanobacteria killers, sedimentation tanks, etc., but the use of a variety of equipment faces the problem of high operating costs, including equipment maintenance, energy consumption, etc., so artificial wetland purification technology is derived. Artificial wetland purification technology has the advantages of low cost, environmental protection, and sustainability. However, the traditional artificial wetland purification technology has low treatment efficiency and cannot completely remove some difficult-to-degrade organic substances or heavy metals. The treatment effect of these specific pollutants is limited, so it will lead to poor tailwater treatment effect, and direct discharge will still cause pollution to the water environment.
