Abstract

The invention relates to an apparatus for field culture of a biomembrane. The biomembrane field culture apparatus comprises a disc carrier and an active carbon fiber fixed disc; the disc carrier comprises discs (1), fixed columns (2), lacing holes (3) and connection holes (4); the active carbon fiber fixed disc comprises annular pads (5), fixed holes (6) and active carbon fibers (7); the active carbon fiber fixed disc is fixed on the disc carrier by fixing ropes (8) which pass through the lacing holes (3), and the discs are mutually connected in virtue of the fixing ropes (8) which pass through the connection holes (4). The apparatus provided in the invention is mainly used for field culture of a biomembrane. The apparatus can culture a uniform high-quality biomembrane approaching natural conditions for ecological monitoring, replace an attachment material of the biomembrane as needed and retain stability and effective enrichment in a natural water body.

Description

[0001] A biofilm field cultivation and collection device technical field [0002] The invention relates to the fields of environmental pollution monitoring and evaluation and ecological restoration, which is used for ecological monitoring and can realize rapid cultivation and collection of biofilms in natural water bodies. Background technique [0003] Biofilms can grow on any interface in water, such as stones, sediments, various aquatic plants, etc., and are mainly composed of algae, bacteria, fungi, micro organisms and mucopolysaccharide matrix. Due to its wide distribution, small size, short life cycle, and sensitivity to various human disturbances, biofilm has gradually become an important means of water quality biological monitoring and evaluation in recent years. Although biofilms grown on natural substrates are easy to obtain, differences in substrates often lead to differences in biofilm structure and composition, which can easily cause errors in water quality monit...
