A biological filler fixing device for river ecological management

Abstract

The invention specifically relates to a biological filler fixing device used for river channel ecological management. The device includes a fixed ring, a rope and a biobase, the biobase is fixed on the rope in the shape of a brush, one end of the rope is fixed on the fixed ring, the fixed ring is rotatably arranged in the water body and one side of the fixed ring is evenly arranged A rope, the lower end of the fixing ring is 1-3cm away from the bottom of the river. In the present invention, by fixing the bio-base on the rope and fixing the rope on the fixed ring, the bio-base is evenly distributed and fully in contact with the polluted water body; by regularly rotating the fixed ring, the amount of biofilm on the bio-base on the rope is basically Evenly distributed, the aging biofilm falls off in time and flows away with the water flow; the indigenous flora at the bottom are better attached to the biological base of each rope and in contact with polluted water sources; thus achieving better treatment effects.

Description

technical field [0001] The invention relates to the field of water body pollution control by biological fillers, in particular to a biological filler fixing device for river channel ecological management. Background technique [0002] The biofilm method is a method of river ecological management using microorganisms attached to the surface of the filler. The filler is the carrier of the biofilm. Under suitable conditions, the more effective biofilms grow on the filler and the larger the contact area between microorganisms and pollutants, the better the effect of river ecological management. Common fillers can be divided into inorganic fillers and organic polymer fillers. Inorganic fillers such as ceramsite and granular / powder activated carbon have good film-hanging properties due to their hydrophilicity and rough surface. However, these fillers have a high density and will precipitate and accumulate. It is beneficial to the contact and degradation of microorganisms and orga...

Problems solved by technology

Common fillers can be divided into inorganic fillers and organic polymer fillers. Inorganic fillers such as ceramsite and granular / powder activated carbon have good film-hanging properties due to their hydrophilicity and rough surface. It is beneficial to the contact and degradation of microorganisms and organic pollutants; polymer fillers are easy to fix or suspend in water, and have good water conservancy conditions, but these substances are hydrophobic and have smooth surfaces, so it is difficult to attach biofilms, especially Attachment of primary biofilms

[0003] Common organic fillers are divided into three categories according to their shapes: massive, tubular, and fibrous. At present, most of the fibrous bio-based fillers are installed in the form of fixed brackets. The fillers are fixed in water. The filler is fixed on the rope, and then a plurality of ropes are connected and bundled together, and fixed in the river bottom with galvanized steel pipe piles. When the ropes are bundled together, the bio-based filler near the bundled end is tightly attached to each other, which is not conducive to biological The uniform formation of the film is difficult to better contact with pollutants, and the renewal of the biofilm is also slow; most of the biofilm is attached to the bio-based fibers on the left and right sides of the rope, and as time grows, the environment where the biofilm grows becomes more and more difficult. worsening, resulting in slower overall plant governance and low utilization
