Description
Technical Field
The invention relates to the technical field of water pollution treatment, in particular to a floating frame for fixing myriophyllum elatinoides and a method for treating eutrophic water.
Background
Eutrophication (eutrophy) refers to the phenomenon that under the influence of natural and human activities, the concentration of nitrogen and phosphorus and other nutrient elements in surface water bodies such as lakes and rivers is greatly increased, so that a large amount of algae and other plankton are increased and propagated, the DO concentration of the water body is reduced, the water quality is seriously deteriorated, aquatic plants and animals die in a large amount, and the balance of an aquatic ecosystem is damaged. The increase of nutrient substances such as nitrogen and phosphorus is the root cause of water eutrophication, the excessive concentration of nitrogen in the water can cause the mass propagation of phytoplankton and algae thereof, the water is covered, the transparency of the water is reduced, sunlight cannot penetrate through a permeable layer easily, the photosynthesis of aquatic plants is inhibited, the water environment is damaged, and the aquatic organisms die in a large amount.
The method for restoring water eutrophication mainly comprises physical, chemical and biological methods. The physical method comprises sediment dredging and clearing, water diversion and dilution and the like, the sediment dredging can improve the water quality condition in a short time, but the environmental conditions of the water body, such as the basic physicochemical properties of the sediment, the concentration of nutrient elements and the like, need to be comprehensively analyzed, the concentration of nutrient salts and suspended matters in the water body are increased easily, the water body is turbid, and the transparency is reduced. The concentration of nutrient elements in the water body can be obviously reduced by water diversion dilution, but the method needs a large amount of pollution-free fresh water and is only suitable for shallow water bodies. The chemical method mainly comprises the steps of adding a chemical reagent into the water body, changing the oxidation-reduction potential of the water body, adjusting the pH value of the water body, and changing the existing form of nutrient salt to reduce the solubility of nutrient elements, but the water body environment is easy to damage, and the biological diversity of the water body is reduced. The physical and chemical methods can improve water quality in a short time, but all have the defects of high cost and easy secondary pollution.
Compared with physical and chemical remediation, the aquatic plant remediation has the advantages of low energy consumption, economy, environmental protection, contribution to the reconstruction and restoration of an aquatic ecosystem and the like. The aquatic plants can effectively remove nitrogen in the water body, so that the nitrogen concentration of the water body is kept in a lower concentration range, and the eutrophication of the water body is effectively controlled.
The foxtail green algae is one of the most important aquatic plants in the world, the lower part of the foxtail green algae is submerged in water, the upper part of the foxtail green algae is exposed out of the water surface, the height of the foxtail green algae can reach 30cm generally, and rhizomes are creeping in water or sludge and are strong in environment adaptation capacity and fast in growth speed. CN 103449607A discloses a method for treating river pollution in plain river network areas by using foxtail green algae, which comprises the steps of arranging wooden piles in the river, driving the wooden piles into the river bottom, fixing a beam above and below the wooden piles respectively, and fixing the foxtail green algae by binding wooden bars or bamboo sheets between the upper and lower beams. However, the device for immobilizing watermifoil is not mobile and has poor positional stability.
