Problems solved by technology

[0005] The technical problem to be solved in the present invention is to overcome existing defects, provide a kind of submerged plant, filler united water body purification system, mainly adopt two kinds of methods to solve the plantation of current river and lake bottom submerged plant proposed in the above-mentioned background technology: Direct drop seed planting and cutting planting
The direct planting technology is even more unable to solve the impact of water disturbance and impurities on the hard bottom

Embodiment 1

[0029] The materials used in polymer and plant fiber mat 5 are non-woven fabrics and stainless steel wire mesh, and the anti-shock flow rate is ≥ 3m / s. The materials used in the porous screen 6 on the top layer are stainless steel mesh and geogrid, and the mesh diameter is less than The diameter of the filler has a high porosity, good water permeability and strong stability. In view of the difficulty and low survival rate of planting submerged plants in the hard bottom mud, three submerged plant planting strips 3 are specially used to fill the plant planting base 2 and submerged plant seeds 1 can effectively prevent seeds from being washed away by water or consumed by other organisms.

Embodiment 2

[0031] Aiming at the problem of low efficiency of adsorbing pollutants by relying solely on aquatic plants in eutrophic water bodies, a specially developed combination filler 4 is filled in the gaps between the three ecological bags of the device. , Large specific surface area, durable, non-dissolving harmful substances, hydrophilic materials, efficient absorption of pollutants in water.

Embodiment 3

[0033] By filling the middle storage space with the combined filler and the plant planting base in the submerged plant planting strip, the density of the matrix material is greater than that of water, relying on the gravity of the material, it is convenient for laying on the bottom of the water during the construction process, and the root system of the submerged plant can be The plant grows from the gaps of the submerged plant planting bar 2 and the porous screen 4 and takes root in the mud at the bottom of the water body, which can well fix the planting position and solve the problem that submerged plants are difficult to transplant.

[0034] The working principle and application process of the present invention: when in use, the combined filler 4 and the submerged plant planting strip 3 are placed between the polymer and plant fiber mat 5 and the porous screen 6, and the submerged plant planting strips 3 are distributed at intervals in the combination 4 fillers, polymer and ...

Abstract

The invention discloses a submerged plant and filler combined purification system for water. The system comprises submerged plant seeds, a plant planting medium, submerged plant planting strips, combined fillers, a polymer and plant fiber mesh mat and a porous screen; the submerged water plant planting strips, the combined fillers, the polymer and plant fiber mesh mat and the porous screen form the purification system for the water; the combined fillers and the submerged plant planting strips are arranged between the polymer and plant fiber mesh mat and the porous screen, the submerged plant planting strips are distributed among the combined fillers at intervals, and four edges of the polymer and plant fiber mesh mat and the porous screen are respectively fixed and form ecological blankets; and four corners of each ecological blanket are provided with holes, and a rope passes through the holes to fix a plurality of ecological blankets. The system provided by the invention solves the problem of difficulty in planting submerged plants at the bottom of a hardened riverbed, can remove pollutants in the water by filling the functional fillers, and realizes convenient planting and quickeffects.

Description

technical field [0001] The invention belongs to the technical field of water ecological restoration, and in particular relates to a water purification system combined with submerged plants and fillers. Background technique [0002] Water eutrophication has developed into a global water environment problem in recent years. The main cause of water eutrophication is the massive discharge of industrial wastewater, agricultural sewage and domestic sewage, resulting in a sharp increase in the concentration of nitrogen and phosphorus in water. Among the bioremediation methods, rebuilding the submerged plant community structure is considered to be an effective means to restore eutrophic water bodies. Submerged plants can reduce the nutrient level of the water body through nutrient absorption of nitrogen and phosphorus, inhibit the release of sediment phosphorus, and promote nitrogen denitrification, and can inhibit the growth of algae through nutrient competition and allelopathy. ...
