Problems solved by technology

However, the existing biological floating island technology has poor impact resistance, the use of aquatic plants has limited absorption capacity, and the removal rate of nitrogen and phosphorus elements is low. Therefore, it is necessary to set up floating islands that occupy more than 20% of the water area to achieve a certain purification effect. Lead to high initial investment and post-maintenance costs

Embodiment 1

[0017] A biological floating island that combines terrestrial plants and microorganisms, such as figure 1 As shown, including biological floating island unit 1, the area of ​​each biological floating island unit 1 is 0.1m 2 . The biological floating island unit 1 includes a vegetation layer 2, a substrate layer 3, a buoyancy base plate 4 and a weight 5. The base layer 3 is contained in the buoyancy base plate 4, the vegetation layer 2 covers the surface of the base layer 3, and the root system penetrates into the base plate. In layer 3, the buoyancy base plate 4 carries the matrix layer 3 and the vegetation layer 2 to float on the surface of the water body, the weight 5 sinks in the water body, the weight 5 and the bottom of the buoyancy base plate 4 are flexibly connected, and the surface of the weight 5 is provided with microgrooves 10. Microgrooves 10 are embedded with microbial filler particles 6 .

Embodiment 3

[0026] Embodiment 3 is the same as Embodiment 1, except that the biological floating island unit 1 has an area of ​​0.4m 2 .

[0027] The matrix layer 3 includes perlite with a mass fraction of 8%, ceramsite with a mass fraction of 8%, river sand with a mass fraction of 10%, decomposed cottonseed shells with a mass fraction of 6%, and decomposed cattle shells with a mass fraction of 15%. Manure and the rest of the garden soil. The microbial filler particles 6 include 0.5% of Bacillus dry powder, 1% of denitrifying bacteria dry powder and the rest of activated carbon, and the Bacillus dry powder and denitrifying bacteria dry powder are adsorbed on the surface of the activated carbon. The bacillus is bacillus licheniformis, and after the bacillus licheniformis is fermented, the bacteria sludge obtained after centrifugation at 12,000 rpm is freeze-dried to obtain the dry powder of the bacillus licheniformis. After the denitrifying bacteria are fermented, the bacteria sludge obt...

Abstract

The invention relates to a biological floating island, and discloses a terrestrial plants and microorganisms combined biological floating island. The biological floating island comprises a biological floating island unit (1), wherein the biological floating island unit (1) comprises a vegetation layer (2), a matrix layer (3), a buoyancy basal disc (4) and a heavy hammer (5), the matrix layer (3) is accommodated in the buoyancy basal disc (4), the vegetation layer (2) covers the surface of the matrix layer (3), root systems are inserted in the matrix layer (3), the buoyancy basal disc (4) bearing the matrix layer (3) and the vegetation layer (2) floats on the surface of water, the heavy hammer (5) is sunk in the water, the heavy hammer (5) is flexibly connected with the bottom of the buoyancy basal disc (4), and microorganism filler particles (6) are embedded in the surface of the heavy hammer (5). The biological floating island disclosed by the invention is simple in structure and low in cost, and treats polluted water by using the synergistic effect of microorganisms and terrestrial plants, and indexes such as water purification efficiency, purification time and set-up area of the biological floating island are all superior to those of traditional biological floating islands.

Description

technical field [0001] The invention relates to a biological floating island, in particular to a biological floating island in which terrestrial plants and microorganisms are combined. Background technique [0002] With the rapid development of industry and agriculture, the water quality of most rivers, lakes and reservoirs has gradually deteriorated, presenting a state of eutrophication, resulting in a large number of algae blooms and foul odors, affecting the proper role of rivers in drinking, irrigation and breeding, and hindering the national economy. development, but also reduce the surrounding air quality, affect the river landscape, and reduce people's quality of life. [0003] The eutrophication of water bodies is mainly caused by excess nitrogen and phosphorus elements in water bodies. Nitrogen and phosphorus elements mainly come from domestic sewage, industrial wastewater and farmland drainage. Since it is currently impossible to centrally treat all sewage, it is...
