Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of breeding tail water treatment, and specifically relates to a bacteria-algae symbiotic pool for treating tail water. BACKGROUND

[0002] In recent years, the aquaculture industry has developed rapidly and become an important industry to meet the demand for human fisheries. However, with the expansion of the scale of aquaculture, the problem of discharge of aquaculture tail water has become increasingly prominent. Aquaculture tail water contains a large amount of suspended particulate matter, feces, leftover feed and dissolved nitrogen and phosphorus nutrients. If it is discharged directly without effective treatment, it will lead to eutrophication of water bodies and cause water bloom phenomenon, causing serious threat to water ecological environment and aquatic biodiversity. In addition, untreated tail water may violate relevant environmental protection standards and face strict discharge supervision and economic penalties. Therefore, efficient treatment technology of aquaculture tail water has become a problem that needs to be solved in the process of sustainable development of aquaculture.

[0003] Bacteria-algae symbiotic technology is a natural biological treatment method combining the characteristics of bacteria and algae. It has attracted much attention because it can simultaneously degrade organic pollutants and absorb nutrients. In the bacteria-algae symbiotic system, bacteria metabolize and decompose organic pollutants in tail water, releasing carbon dioxide and other metabolites; algae grow through photosynthesis using these metabolites while absorbing nitrogen and phosphorus elements in tail water. The synergistic effect of bacteria and algae not only purifies water quality, but also improves the treatment efficiency of the system, making it a green, low-cost and environmentally friendly water treatment technology.

[0004] However, the existing bacteria-algae symbiotic treatment equipment still has the following technical defects in actual application:

[0005] Traditional bacteria-algae symbiotic equipment usually needs to set backflow devices and filtration devices respectively. The backflow devices and filtration devices are connected to the symbiotic pool through multiple independent pipelines, which not only increases the number and arrangement difficulty of the pipelines, but also makes the overall structure more complex, affecting the installation and maintenance efficiency of the equipment, and requires independent water pumps and water valves for the backflow devices and filtration devices respectively, which has high manufacturing cost. In addition, the existing bacteria-algae symbiotic equipment usually needs to be additionally connected to an external independent filtration pool, which occupies a lot of space and is difficult to apply in places with limited space.

[0006] Therefore, in view of the above problems, there is an urgent need for a bacteria-algae symbiotic treatment equipment with simple structure, small space occupation and low cost, which not only solves the problem of sediments in tail water, but also realizes deep filtration and flexible regulation of tail water, ultimately improving the treatment efficiency and discharge standard level of aquaculture tail water.
