Embodiment 1

[0041] Example 1 An ecological floating bed combination for biological treatment of surface polluted water

[0042] An ecological floating bed combination for biological treatment of surface polluted water, which includes: plants and substrates;

[0043] The plant and its ratio are water calamus: rice: water celery=1:1.25:1.28;

[0044] The matrix and its ratio are 20.89% of ceramsite, 0.54% of straw biochar, and 78.57% of gravel;

[0045] The plants described in the aforementioned ecological floating bed combination are fixed with a substrate, and planted in the water body of the Yitong River to purify the water quality and increase the ornamental value of the plants.

Embodiment 2

[0046] Example 2 An ecological floating bed combination for biological treatment of surface polluted water

[0047]An ecological floating bed combination for biological treatment of surface polluted water, which includes: plants and substrates;

[0048] The plants and their proportions are 25.69% of canna, 8.33% of water onion, 8.33% of water celery, 24.31% of rice, 19.44% of water calamus, and 7.64% of iris;

[0049] The matrix and its ratio are 22.5% of ceramsite, 0.45% of straw biochar, and 77.05% of gravel;

[0050] Fix the plants described in the above-mentioned ecological floating bed combination with a substrate, plant them in the water body of Yitong River, and plant cannas on the outermost periphery; Increase plant ornamental.

Embodiment 3

[0051] Example 3 A biological treatment method for surface polluted water

[0052] A method for biological treatment of surface polluted water, comprising:

[0053] 1) Select aquatic plants, such as rice, water calamus, canna, water onion, water celery, iris, and clean them;

[0054] 2) Slow seedlings and domesticate them with sewage;

[0055] 3) Fix the domesticated plants with substrates such as ceramsite, straw biochar or gravel, and plant them in lightly polluted water bodies.

[0056] The above-mentioned aquatic plants are fixed with a matrix, the planting ratio is determined according to the purification effect, and the planting is planned according to the plant ornamental and the diversity of the growth period to purify the water quality.

Abstract

The invention discloses an ecological floating bed combination for biological treatment of surface polluted water. The ecological floating bed combination comprises plants and a matrix, the plant is at least one of rhizoma acori calami, rice, canna indica, iris tectorum, scirpus tabernaemontani and oenanthe javanica; the substrate is ceramsite, biochar and / or gravel; the biological treatment method for the surface polluted water body has the advantages that (1) ceramsite and biochar have certain adsorption capacity on pollutants in the floating bed water body, a good growth environment is provided for microorganisms while a good attachment point is provided for a plant root system, and the water quality purification effect is improved; (2) the plants are fixed by adopting ceramsite, so that the maintenance and management difficulty of easy lodging plants such as canna, iris tectorum and the like is reduced; (3) the ecological floating bed can better degrade pollutants in a medium-high-concentration water body, enough nutrient elements for plant growth exist in the high-concentration pollutant water body, the removal effect on the pollutants is enhanced while the plant growth is promoted, and the ecological floating bed has a good application prospect. Economic benefits and social benefits are achieved; (4) the purification effect of mixed planting of plants is higher than that of independent planting, and the mixed planting of plants is more suitable for water bodies with large water level change differences.

Description

technical field [0001] The invention belongs to the technical field of biological treatment of water bodies, and in particular relates to an ecological floating bed combination for biological treatment of surface polluted water bodies. Background technique [0002] The rapid development of urbanization has aggravated the pollution of rivers, lakes, reservoirs and other water bodies. The pollution of surface water not only accelerates the deterioration of water environment, but also seriously affects the safety of drinking water. In recent years, human activities have led to serious organic pollution of rivers, lakes and park surface water, and problems such as eutrophication. Urban rivers are an important part of urban ecosystems and river basin water systems. They have multiple functions such as flood drainage, water supply and transportation, transportation, leisure and entertainment, pollution purification, biodiversity protection, and microclimate improvement. Therefore...
