Problems solved by technology

[0002] In recent years, with the improvement of human living standards and the development of materials, water pollution has become a common problem in the world today. Plant purification has received extensive attention in the treatment of water environment and pollution, but the use of plants for water treatment In the process of purification and purification, aquatic plants usually purify the water body, without fully considering the surrounding environment of the water to be purified and the impact of plants on the purification of the water body, which makes the water purification not comprehensive and comprehensive

Embodiment 1

[0070] A water purification method using aquatic plants and shore vegetation according to an embodiment of the present invention, said method comprising:

[0071] Obtain the shore information and water body information of the water area to be purified, the shore information may include shore soil information, shore climate information and shore terrain information, and the shore soil information may include total nitrogen content, total phosphorus content, At least one of ammonia nitrogen content, available phosphorus content, and organic matter content; the water body information can include water body quality information and water body environmental information, and the water body quality information can include water body pH value, nitrate nitrogen content, nitrogen content, phosphorus content, At least one of oxygen solubility, chemical oxygen demand and biochemical oxygen demand, and the water body environment information may include at least one of water body temperature,...

Embodiment 2

[0075] A water purification method using aquatic plants and shore vegetation according to an embodiment of the present invention, said method comprising:

[0076] Obtain shore information and water body information of the water area to be purified.

[0077] Obtain growth characteristic data and water purification data of coastal vegetation and aquatic purification plants.

[0078] The growth characteristic data and water body purification data of the shore vegetation and aquatic purification plants are used to analyze and match the shore information and water body information to determine the planting parameters of the shore vegetation and aquatic purification plants.

[0079] The shore vegetation and aquatic purification plants are planted according to the planting parameters of the shore vegetation and aquatic purification plants.

Embodiment 3

[0081] A water purification method using aquatic plants and shore vegetation according to an embodiment of the present invention, said method comprising:

[0082] Obtain shore information and water body information of the water area to be purified.

[0083] Obtain growth characteristic data and water purification data of coastal vegetation and aquatic purification plants.

[0084] Using the growth characteristic data and water body purification data of the shore vegetation and aquatic purification plants to analyze and match with the shore information and water body information, plant reeds, duckweed and weed in the shallow water area to be purified, with a coverage of 30 %, the planting ratio of reeds, duckweeds and chrysanthemums is 4:4:3, and the coastal vegetation includes rose and pennisetum, the width can be 5 meters, the row spacing of shrubs can be 1*1.5 meters, and herbaceous plants The row spacing is 10 cm, and the planting ratio of rose and pennisetum is 1:1.

Abstract

The invention provides a method for purifying a water body by utilizing aquatic plants and riparian vegetation. The method comprises the following steps: obtaining riparian information and water body information of a water area to be purified; according to the riparian information and the water body information, planting the riparian vegetation on the shoreland of the water area to be purified, and planting aquatic purification plants at shoal waters of the water area to be purified, wherein the riparian vegetation comprises shrubs and xeromorphic herbs, the shrubs comprise at least one of roses and Forsythia suspense, the xeromorphic herbs comprise at least one of Pennisetum alopecuroides and Triarrhena lutarioriparia, and the aquatic purification plants comprise at least one of emergent aquatic plants, floating plants and submerged plants. The riparian vegetation grows and absorbs the nutrient substances in riparian soil and overland runoff, so that the water body is purified; the aquatic plants are utilized to absorb the nutrient substances in the water body, so that the synergic purification of the water area to be purified and the shoreland is realized; the effect of the shoreland ecology on water body purification is fully considered, so that the water body is purified comprehensively and effectively.

Description

technical field [0001] The invention relates to the technical field of biological water body purification, in particular to a water body purification method utilizing aquatic plants and coastal vegetation. Background technique [0002] In recent years, with the improvement of human living standards and the development of materials, water pollution has become a common problem in the world today. Plant purification has received extensive attention in the treatment of water environment and pollution, but the use of plants for water treatment In the process of purification and purification, aquatic plants usually purify the water body, without fully considering the surrounding environment of the water to be purified and the impact of plants on the purification of the water body, which makes the water purification not comprehensive and comprehensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water body purific...
