Problems solved by technology

Non-woven fabrics have the characteristics of many pores, large surface area, easy film formation, and low cost, but they still have the following disadvantages: (1) poor physical and chemical properties, easy to entangle, unable to shape, and less hydraulic load resistance in water; (2) After a period of time, it is easy to break down and not easy to degrade. In severe cases, it needs to be salvaged later, causing secondary pollution; (3) The surface of the material used has poor biocompatibility and hydrophilicity, resulting in slow film formation and low biomass

Embodiment 1

[0019] Such as figure 1 As shown, the artificial aquatic plant monomer for water ecological restoration of the present invention includes grass fiber 3 , polypropylene fiber main rope 2 , float 1 and bottom anchor 4 . There are a plurality of floats 1, uniformly fixed on the polypropylene fiber main rope 2, providing buoyancy for the artificial grass body, keeping it upright in the water body, and ensuring the largest contact area. The grass fiber 3 is made of bio-affinity, hydrophilic and aging-resistant modified polylactic acid fiber, and the bottom anchor 4 is connected with a plurality of grass fibers 3 through the main rope 2 . Grass fiber 3 adopts polylactic acid with a length of 5-20cm, good stability and slow decomposition. Polylactic acid can be completely degraded into H 2 O and CO 2 , It can guarantee two years of normal operation in natural water bodies; after complete degradation, it will not cause secondary pollution to the water body environment. Bottom ancho...

Embodiment 2

[0021] Such as figure 2 As shown, the group of artificial aquatic plants is composed of a plurality of artificial aquatic plant monomers 5 for water ecology restoration of Embodiment 1. Restoration of water ecology The middle part of the artificial aquatic plant monomer 5 is fixed with a lightweight frame 6 to prevent the artificial aquatic plants from being entangled in the water. The number of artificial aquatic plants shall be configured according to 5% to 20% of the area of ​​the water body to be treated. The height of the artificial aquatic plants is set according to the actual water depth, 20-50cm away from the water surface, which does not affect the sailing. Water Ecological Restoration Artificial aquatic plants are similar to natural aquatic plants and do not affect the water landscape.

[0022] The artificial water plant group described in the present invention can be directly placed in the water body to be treated. The artificial water plant group can quickly for...

Embodiment 3

[0024] Such as image 3 As shown, a plurality of artificial aquatic plant monomers 5 for water ecological restoration of Example 1 are combined with the ecological floating bed 7, and placed in the water body in a suspended manner, and a plurality of artificial aquatic plant monomers 5 are suspended under the ecological floating bed 7 per square meter, so that The artificial aquatic plants and the ecological floating bed promote each other. On the one hand, the plants on the ecological floating bed 7 can provide trace amounts of oxygen to the microorganisms attached to the artificial aquatic plants 5; purification effect.

[0025] Artificial aquatic plants have become a commonly used method for water ecological management, because their huge specific surface area provides a huge attachment area for microorganisms, greatly increases the biomass, and makes the water quality can be quickly purified. Artificial aquatic plants purify water mainly by adsorption and microbial degrad...

Abstract

The invention discloses artificial water weeds for water ecological restoration and application thereof. The artificial water weeds mainly comprise water weed fibers, a main rope, floats and a bottom anchoring part, wherein the water weed fibers are made of modified polylactic acid fibers; the bottom anchoring part is connected with the water weed fibers by virtue of the main rope; and multiple floats are uniformly distributed on the main rope, so that the artificial water weeds for water ecological restoration form an upright shape in water. Because the biodegradable polylactic acid fibers with biological affinity and hydrophilcity serve as artificial water weed materials, rapid biofilm culturing can be realized, and the biomass is increased. Meanwhile, the artificial water weeds are gradually and naturally degraded; on the one hand, a carbon source is provided for attached microbes, and the water quality purification effect is enhanced; on the other hand, self-degradation is realized, and later-stage white pollution is alleviated.

Description

technical field [0001] The invention belongs to the technical field of water ecological environment protection, in particular to an artificial aquatic plant applied to the ecological restoration of urban rivers and artificial lakes. Background technique [0002] In eutrophic lakes, restoring aquatic plants can improve the self-purification ability of water bodies and curb the occurrence of cyanobacteria blooms. However, in fact, the recovery of aquatic plants, especially the recovery of submerged plants that can grow on a large scale in the central waters of the lake, requires certain conditions. On the one hand, plant growth requires sufficient sunlight; on the other hand, the concentration of nutrients cannot too high. However, in the water bodies that need to be treated urgently today, the visibility is very low, and the center of the water body, and even the shore cannot allow direct sunlight to the bottom of the pool; at the same time, the heavily polluted water body t...
