Flow-guide type ecological floating bed suitable for high-flow-speed water body

Abstract

The invention discloses a flow-guide type ecological floating bed suitable for a high-flow-speed water body. The flow-guide type ecological floating bed comprises a floating bed body and a floating bed fixing device, wherein the floating bed body comprises a planting matrix, side wing plates and flow guide plates, wherein the side wing plates are installed at the both sides below the planting matrix, two W-shaped flow guide plates are installed at the middles of the two side wing plates, and aquatic plants are placed on the planting matrix; the floating bed body is fixed on a riverbed by a floating bed fixing rope and a floating bed rod. The flow-guide type ecological floating bed disclosed by the invention is capable of effectively reducing the speed of a water flow at the bottom of the floating bed, protecting the formation and development of biological membrane structures on the surfaces of root systems, increasing the hydraulic retention time of the water flow in the root areas of the plants, and increasing the absorption and degradation efficiency of the root systems of the plants to pollutants in a high-flow-speed environment, as well as adaptive to the water quality purification need of the high-flow-speed water body.

Description

technical field [0001] The invention relates to a device for purifying polluted river water, in particular to a diversion type ecological floating bed suitable for large flow rate water bodies, which belongs to the field of water environment protection. Background technique [0002] With the increase of regional population density and the rapid development of social economy, the discharge of domestic and industrial sewage has increased rapidly, and the pollution load of many rivers has approached or exceeded its critical value, and the pollution situation is severe. According to reports, nearly 60% of the water bodies in the country have been polluted and damaged to varying degrees, and the restoration and protection of the water environment has become an urgent problem to be solved in our country and even in the world. At present, many effective water environment treatment technologies have been developed at home and abroad. Among them, ecological restoration measures are v...

Problems solved by technology

[0004] But at present, many large-velocity rivers such as lakes and rivers are also facing serious pollution problems. In such rivers with high velocity, the continuous impact of water flow on the root system of floating bed plants is not conducive to the formation and development of biofilm on the surface of the root system. At the same time, the number of microorganisms and aquatic animals around the root system will be greatly reduced, and the hydraulic retention time of the water flow in the root area of ​​​​the floating bed is relatively short, which is very unfavorable for the removal of pollutants in the water body

Therefore, ordinary floating beds are difficult to play a role in these high-velocity rivers, and there is an urgent need for an efficient artificial ecological floating bed that can be applied to high-velocity water bodies.
