Biological filler fixing apparatus for river course ecological management

Abstract

The invention particularly relates to a biological filler fixing apparatus for river course ecological management. The apparatus comprises fixing rings, ropes and biological bases, wherein the biological bases are fixed on the ropes in a hair brush manner, one end of the rope is fixed on the fixing ring, the fixing ring is rotatably arranged in a water body, one side of the fixing ring is uniformly provided with a plurality of ropes, and the distance between the lower end of the fixing ring and the bottom of river is 1-3 cm. According to the present invention, the biological bases are fixed onthe ropes, and the ropes are fixed on the fixing rings, such that the biological bases are uniformly distributed and fully contact the polluted water body; by periodically rotating the fixing rings,the amounts of the biofilms on the biological bases at various parts of the ropes can basically achieve uniform distribution, and the aged biofilm falls off in time and flows away with the water flow;and the indigenous flora on the bottom portion can be well attached to the biological bases on each rope and contact the polluted water source so as to achieve the good treatment effect.

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
