Biofilm scaffolds for cryogenic environments

Abstract

The invention discloses a biofilm colonization support for a low-temperature environment. The biofilm colonization support is characterized by comprising an upper-layer frame (1), a bottom-layer frame (3) and supporting columns (2); the bottom-layer frame (3) and the upper-layer frame (1) are the same in structure and are parallel, the supporting columns (2) are connected with the bottom-layer frame (3) and the upper-layer frame (1), the bottom-layer frame (3) is communicated with at least one supporting column (2), the bottom-layer frame (3) is provided with a downward air hole (6), and supporting legs (4) are arranged on the bottom-layer frame (3). The support is simple in structure and low in cost; air or oxygen can be led in through the air hole, led-in airflow can drive water biological stuffing to move continuously, the content of dissolved oxygen in water is increased, biofilm colonization under the low-temperature condition can be conveniently achieved, and the biofilm colonization support is suitable for application and popularization.

Description

technical field [0001] The invention relates to a support for biofilm, in particular to a biofilm support for low temperature environment. Background technique [0002] Professional circulating water fish farming needs to provide fish with a suitable water environment for growth. Fish will produce excrement during the growth process, and the water environment where fish live will also produce other garbage. Therefore, the water where fish lives needs to be cleaned. The method of biofilm is usually used to clean the water for fish farming. However, for the cold water environment with a low temperature of 12-18 °C, it is difficult to bio-film, and the biological filler used for bio-film is easy to accumulate and sink to the bottom, which in turn affects the normal growth and reproduction of microorganisms, and makes microorganisms carry out harmful effects such as ammonia nitrogen and nitrite. The efficiency of the material decomposition work is low, that is, the cleaning eff...
