Embodiment

[0019] refer to Figure 1-2 , a purification device for ecological restoration of water bodies, which includes an air floating island 1, a water surface floating island 2 and an underwater floating island 3, wherein the air floating island 1 includes a supporting frame 4 and land plants 5 arranged on the supporting frame 4 , the water surface floating island 2 includes a floating island unit 6 and emergent plants 7, and the underwater floating island 3 includes microbial hanging film parts 8 and submerged water / floating leaf plants 9, wherein the floating island unit 6 includes an emergent plant planting area 17 and submerged water / Floating leaf plant planting area 16, support frame 4 is arranged on emergent water plant planting area 17 and submerged / floating leaf / plant planting area 16, microbial hanging film part 8 is suspended on emergent water plant planting area 17 and submerged water / floating Below the leaf plant planting area 16 , the submerged / floating leaf plant 9 is...

experiment example 1

[0025] Experimental water body: river gushing, the main pollution sources are residential domestic sewage that has not been completely intercepted, factory production wastewater, and urban non-point source pollution.

[0026] Experimental method: select a river section about 100m long in the river, the river width is 6-8m, and the water depth is about 2m. Four groups of combined ecological floating islands of the present invention are arranged near the center of the river channel, and are connected and fixed with steel cables.

[0027] The planted water purification type plants include emergent plants and floating plants (the area ratio is 1:1).

[0028] The trial started in September 2010 and ended in April 2011. The plants used include windmill grass, canna, water ghost banana, foxtail algae and penny grass, and the plants can grow normally, thus ensuring the effective performance of the water purification function of the combined ecological floating island system. During t...

experiment example 2

[0030] Experimental water body: the water area is about 3000m 2， A lake with a water depth of about 2-3m. The main pollution sources of this lake are non-point source pollution such as residential sewage that has not been completely intercepted, farmland, road runoff, etc. The water body of the lake is yellow-green, and the transparency is less than 20cm. It belongs to the inferior V class eutrophic water body .

Abstract

The invention discloses a purifier for ecological restoration of a water body. The purifier comprises a floating island in the air, a floating island on the water and a floating island beneath the water, wherein the floating island in the air comprises a supporting framework and terrestrial plants arranged on the framework, the floating island on the water comprises a floating island unit and emergent plants, the floating island beneath the water comprises a microorganism biofilm forming member and submerged/floating-leaved plants, the floating island unit comprises a planting area for the emergent plants and a planting area for the submerged/floating-leaved plants, the supporting framework is arranged on a planting area for aquatic plants, the microorganism biofilm forming member is hung below the planting area for aquatic plants, and the submerged/floating-leaved plants are arranged in the planting area for the submerged/floating-leaved plants. The invention has the following advantages: a stereo ecological environment can be constructed according to growth needs of different plants, air in and above a water body can be purified at the same time, easy attachment of microorganisms is realized, which is beneficial for establishing good ecological balance, a multi-level structure has strong adaptability, and abundant landscape effects can be obtained.

Description

technical field [0001] The invention relates to a purification device, in particular to a purification device for ecological restoration of water bodies. Background technique [0002] Under the influence of human activities, a large number of pollutants containing nitrogen, phosphorus, and organic matter enter ponds, lakes, rivers and other water bodies, and the nutrients in them will cause algae and other plankton to multiply rapidly, resulting in a decrease in dissolved oxygen content in water bodies and deterioration of water quality. , a large number of fish and other organisms die; and the toxic and harmful pollutants entering the water body can directly affect the living objects in the water body, thereby destroying the benign and healthy aquatic ecosystem. With the development of human industry, the pollution of water bodies is increasing day by day, which has a negative impact on human survival. [0003] At present, the common means of treating polluted water bodies...
