Embodiment 1

[0032] like Figure 1~2 As shown, a method suitable for in-situ restoration of slightly polluted water bodies specifically includes an ecological floating bed 1 and a modified fiber tape braid 2 located at the lower part of the ecological floating bed. The ecological floating bed 1 includes a bed body, and a filter material is laid in the bed body 3. Ecological plants 4 are planted on the filter material 3 .

[0033] Among them, the specification of the ecological floating bed 1 is set at 3 m×5 m. The bed body is made of environmentally friendly polyethylene material, and the outer surface is coated with waterproof and anti-corrosion paint. ~10 cm thick filter material 3, the filter material 3 is formed by mixing organic peat soil, perlite, and cassava residue according to the mass ratio of 5:1:1, and the filter material 3 is planted with a distance of 15 to 20 cm. Green iris, the bottom of the ecological floating bed 1 is 0.5 m apart and hangs a modified fiber tape braid 2 w...

Embodiment 2

[0045]According to the method of embodiment 1, the difference is to change some parameters in the manufacturing steps of the modified fiber tape braid 2:

[0046] 1) Change the concentration of NaOH solution in step (2) to 3%, soak for 8 h;

[0047] 2) Change the modifier in step (4) to powdery material, starch, vinyltriethoxysilane and mix according to the weight ratio of 45:30:5:1;

[0048] 3) Change the amount of microbial solution in step (6) to 450mL / m 2 .

Embodiment 3

[0050] According to the method of embodiment 1, the difference is to change some parameters in the manufacturing steps of the modified fiber tape braid 2:

[0051] 4) Change the concentration of NaOH solution in step (2) to 5%, soak for 8 h;

[0052] 5) Change the modifier in step (4) to powdery material, starch, vinyltriethoxysilane and mix according to the weight ratio of 55:40:6:1;

[0053] 6) Change the amount of microbial solution in step (6) to 400mL / m 2 .

Abstract

The purpose of the present invention is to provide a method suitable for in-situ restoration of slightly polluted water bodies, comprising an ecological floating bed and a modified fiber tape braid located at the lower part of the ecological floating bed, the ecological floating bed is fixed with a nylon rope by piling at the bottom of the water, and the modified The fabric of the modified fiber belt is fixed on the bottom of the ecological floating bed with a nylon rope. The ecological floating bed includes filter material and aquatic plants. The modified fiber belt fabric is woven through the modified fiber belt. With the characteristics of large total water volume, shallow pollution degree, and poor landscape, the restoration mode combining ecological floating bed and modified fiber tape braid is used to create a new type of material suitable for in-situ restoration of slightly polluted water bodies, which is conducive to improving landscape water quality and strengthening self-purification of water bodies Ability, both ecological and landscape, suitable for promotion and use.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a method suitable for in-situ restoration of slightly polluted water bodies. Background technique [0002] River courses are an important support for the urban ecological environment, an important carrier of natural resources and environment, closely related to human production and life, and play a significant role in urban planning and construction. At present, with the acceleration of urban construction, a large amount of untreated domestic sewage and industrial wastewater are discharged into rivers, resulting in the gradual degradation of river ecosystems closely related to human life and the weakening of self-purification capabilities. On the other hand, in recent years, with the improvement of living standards and the quality of human settlements, people's requirements for lakes, rivers and landscapes have also continued to increase, and water landscapes ...
