Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and more specifically refers to an improved aquaculture circulating water dripping filter system. Background Art

[0002] The Chinese patent with authorization announcement number CN 217826405U is an application filed by the applicant. The patent discloses an aquaculture circulating water dripping filter system, including several water tanks, a dripping filter mechanism and an axial flow negative pressure fan. The dripping filter mechanism includes a frame and several layers of rattan cotton. The frame is provided with several layers of support frames at intervals along the vertical direction. Each layer of the support frame is provided with a layer of rattan cotton. There is a distance of at least 30 cm between each adjacent layer of the rattan cotton, and there is also a distance of more than 30 cm between the topmost layer of rattan cotton and the bottom surface of the water tank.

[0003] This patent uses the characteristics of rattan cotton with dense pores and good water permeability and air permeability, which can not only make most of the remaining CO2 in the water body be taken away by the negative pressure airflow, thereby increasing the removal of CO2; but also the multi-layer rattan cotton can filter out the bacterial film, bacteria and insects in the circulating water, cultivate nitrifying bacteria for the circulating water, reduce the concentration of ammonia nitrogen and nitrite, and improve the recycling rate of water. The degradation of nitrite by this system depends to a large extent on the survival of nitrifying bacteria on the rattan cotton, and the degradation effect is difficult to guarantee. In addition, the pH value of the circulating pool water after drip filtration of this system is low, resulting in the need to adjust the pH in the pH adjustment tank after the water is discharged, which increases the pH value adjustment process. To this end, we provide an improved aquaculture circulating water drip filtration system. Utility Model Content

[0004] The utility model provides an improved aquaculture circulating water drip filtration system to solve the problems that the degradation of nitrite in the existing drip filtration system depends on the survival amount of rattan cotton nitrifying bacteria, the degradation effect is difficult to ensure, and a pH regulating tank needs to be added to adjust the pH value of the circulating water after the drip filtration.

[0005] The utility model adopts the following technical solutions:
