Description
Technical Field
The invention relates to the technical field of water ecological restoration, in particular to a device for ecologically reducing organic matters in water bottom and a using method thereof.
Background
The water ecological restoration means that artificial interference is applied to a water ecological system to reduce load pressure and improve the self-regulation capacity and self-organization capacity of the ecological system so as to evolve in an orderly direction, or the self-recovery capacity of the ecological system is utilized and artificial measures are supplemented so as to gradually recover the damaged ecological system or make the ecological system develop in a virtuous cycle direction.
The sludge layer in rivers, lakes and ponds usually contains a large amount of organic pollutants, the sources of the organic pollutants are different, but the organic pollutants are easily deposited in water bodies with smaller hydrodynamic force action, particularly lakes, reservoirs and ponds with relatively static water bodies or wide backwater bays of rivers because the specific gravity of the organic pollutants is slightly higher than that of water. Organic pollutants deposited on the bottom layer of the water body are difficult to decompose and digest, so that the organic pollutants grow thicker and thicker over time and become an 'endogenous pollution source' of the water body.
At present, methods for eliminating 'endogenous pollution sources' of water bodies are mainly divided into 'dry methods' and 'wet methods'. A method for eliminating an endogenous pollution source of a water body by a dry method is generally called as a dry pond, namely draining the water body of a lake or a reservoir or a pond, and then cleaning organic pollutants at the bottom of the lake by a mechanical or manual method; the ' wet method ' for eliminating the endogenous pollution source of the water body ' is divided into a ' disc suction method ' and a ' stirring suction method ', organic pollutants and part of water deposited at the bottom of the water body are pumped to a ' treatment device ' through a machine, and then the organic pollutants are flocculated, precipitated, coagulated, dehydrated, solidified and the like. In the method, a large amount of water resources are lost by ' dry method ' elimination of endogenous pollution sources of the water body ', pollution is actually transferred in the process of draining the water body, in addition, organic pollutants deposited at the bottom of the water release a large amount of ' greenhouse gas ' in the process of drying in the sun, and production and life of surrounding residents are influenced if people live around the water body. The 'wet method' eliminates the endogenous pollution source 'of the water body' and has high treatment cost and poor treatment effect because no matter the 'suction cup method' or the 'stirring and sucking method' can suck a large amount of inorganic silt while sucking the organic silt, the treatment cost is increased, and meanwhile, the construction equipment per se can disturb the organic bottom sediment to be resuspended in the water body, and the treatment effect is poor.
In order to achieve the purpose of water ecological restoration, underwater organic matters need to be reasonably reduced, so that a device for ecologically reducing the underwater organic matters is needed, underwater organic matters are digested and utilized by stirring underwater organic bottom mud and a circulating ecological system consisting of microorganisms, aquatic animals and water surface culture plants, the water ecological restoration is achieved, and the underwater organic pollutants are recycled.
