Description

Technical Field

[0001] The utility model mainly relates to the field of tail water treatment, and specifically relates to a device for synergistically treating aquaculture tail water by algae and bacteria. Background Art

[0002] During or after aquaculture, the tail water discharged from aquaculture systems (including aquaculture ponds, nursery ponds, industrial workshops, etc.) often contains a large amount of elements such as carbon, nitrogen, and phosphorus, which can cause eutrophication of water bodies and even soil, polluting the natural environment and affecting production and life. Similar to other types of wastewater, the treatment methods for aquaculture tail water can be roughly divided into three categories: physical, chemical, and biological. It is worth noting that in addition to being used as a raw material for biomass energy production, microalgae also exhibit excellent characteristics in water purification. By constructing an algae-bacteria symbiotic body, complementary advantages can be formed to synergistically purify water and improve the water purification efficiency. Among them, algae release oxygen through photosynthesis to supply the metabolic activities of aerobic heterotrophic microorganisms, and aerobic microorganisms oxidize and decompose organic pollutants. The metabolic products carbon dioxide, inorganic nitrogen, and phosphorus compounds are then supplied to algae as the carbon source and nutrients required for photosynthesis. In this way, a mutualistic relationship between bacteria and algae is formed.

[0003] In the invention patent application with the application number CN202211254594.X, the publication date of December 16, 2022, and the title of "A Device and Method for Synergistically Treating Aquaculture Tail Water by Algae and Bacteria", it includes an aquaculture department. One end of the bottom of the aquaculture department is connected to one end of a sewage discharge department, and the other end of the sewage discharge department is connected to the bottom of a tail water treatment department. The upper side wall of the tail water treatment department is connected to the upper side wall of the aquaculture department. The sewage discharge department includes a sewage discharge pipe connected to the bottom of the aquaculture department. The end of the sewage discharge pipe far from the aquaculture department is connected to the bottom of the tail water treatment department, and a sewage pump is arranged on the sewage discharge pipe. This device improves the fluidity and stability of the algae-bacteria reaction liquid by using a guide plate, realizing the improvement of the quality and efficiency of aquaculture tail water treatment.

[0004] However, in the actual use process of this treatment device, the recovery of algae is relatively cumbersome and requires manual filtration and collection. Summary of the Utility Model
