Abstract

The invention relates to a device for rapidly culturing biological films in natural water body, which consists of a disc carrier and an active carbon fiber fixing disc, wherein the disc carrier comprises discs (1), a fixed column (2), a rope penetrating hole (3) and a connecting hole (4); an active carbon fiber fixing device comprises a ring-shaped gasket (5), a fixed hole (6) and active carbon fiber (7); the active carbon fiber fixing disc is fixed on the disc carrier by a fixing rope (8) through the rope penetrating hole (3); and the discs are connected with each other by the fixing rope (8) through a connecting hole (4). The device is mainly used for rapidly culturing the biological films in natural water body in batches. The device can be used for culturing the biological films which are even and close to the natural condition, have high quality, and are used for ecological monitoring, can shortens the cultivation time to be more than 20 days, and can culture the biological films at the different depths in the water body at the same time.

Description

technical field [0001] 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 [0002] 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 monitoring and evaluation. Mainly, the most widely used substra...
