Problems solved by technology

[0006] However, the existing floating islands are mainly frame-type floating islands, foam board-type floating islands, etc. The floating islands formed by this type of technology have complex structures, mainly composed of floating island frames, plant carriers or floating bodies, plants and floating island fixing parts, etc. The structure is complex, so there are a series of problems during use, such as difficult to disassemble, low reuse rate, etc.
In our country, the ecological floating island technology is not perfect in theory and practice, and it is far from solving the serious problem of wetland pollution in our country.

Embodiment 1

[0028] Use PVC to control a frame with a length*width of 2m*2m. The four corners of the frame are used to fix the floating ball. The bottom is covered with a polyethylene net with a net rope thickness of about 2mm and a mesh size of 2cm*2cm. Fold the polyethylene net in two layers to wrap the floating ball. , forming a plant carrier.

[0029] Put the floating island into a cement tank with a radius of 2.2m and a depth of 1.6m, and place water hyacinth seedlings with the same size and good growth at a rate of 10 / m 2 , planted on a plant carrier. Its floor plan see figure 1 shown.

[0030] Sewage is injected into the cement tank, and the water quality of the incoming water is monitored at the same time. After two weeks of purification, the water quality of the released water was monitored. Drain the purified sewage, and then re-inject the sewage to monitor the water quality of the sewage. Similarly, after 2 weeks of purification, monitor the water quality of the sewage. The...

Embodiment 2

[0035] The frame is made of moso bamboo with a length*width of 2m*2m. The bottom of the frame is covered with a nylon rope net with a thickness of about 2mm and a mesh size of 2-4cm*2-4cm. Fold two layers to form a plant carrier.

[0036] Put the floating island into a cement tank with a radius of 2.2m and a depth of 1.6m, and place the large floating islands with the same size and good growth at a rate of 10 trees / m 2 , planted on a plant carrier, its plan view is shown in figure 2 shown.

[0037]Sewage is injected into the cement tank, and the water quality of the incoming water is monitored at the same time. After two weeks of purification, the water quality of the released water was monitored. Drain the purified sewage, and then re-inject the sewage to monitor the water quality of the sewage. Similarly, after 2 weeks of purification, monitor the water quality of the sewage. The sampling time of the experiment was from June to August, and the experiment was repeated 6 t...

Embodiment 3

[0040] The frame is made of moso bamboo with a length*width of 2m*2m. The bottom of the frame is wrapped with a nylon rope net with a thickness of about 2mm and a mesh size of 2-4cm*2-4cm. The seine is folded in two layers to form a plant carrier. Plant big drift and water hyacinth on it. Its floor plan see figure 2 shown.

[0041] Put the floating island into a cement tank with a radius of 2.2m and a depth of 1.6m, and put the water hyacinth seedlings with the same size and good growth + big drift at a rate of 10 / m 2 , configured into the floating island. Sewage is injected into the cement tank, and the water quality of the incoming water is monitored at the same time. After two weeks of purification, the water quality of the released water was monitored. Drain the purified sewage, and then re-inject the sewage to monitor the water quality of the sewage. Similarly, after 2 weeks of purification, monitor the water quality of the sewage. The sampling time of the experimen...

Abstract

The invention provides a lightweight detachable composite ecological floating island which comprises a frame, a carrier and a plant, wherein the carrier is connected to or coated on the plant on the frame; and the plant grows on the carrier of the plant. In the invention, detachable materials are combined for treating polluted wet land; and by combining the function units, pollutants can be effectively removed, and an ecological environment can be improved. The invention has the advantages of high treatment efficiency, low investment, low running cost, low maintenance technology, low energy consumption and wide application range.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering and relates to a light detachable composite ecological floating island and a construction method thereof. Background technique [0002] Ecological floating island technology is to artificially plant higher aquatic plants or improved terrestrial plants on the surface of eutrophic waters in accordance with the laws of nature, and eliminate the enrichment in water bodies through the absorption, adsorption and species competition mechanism of plant roots. Nitrogen, phosphorus and harmful substances, so as to achieve the effect of purifying water quality, and at the same time can create water landscape technology, as a new sewage treatment technology, mainly used in the purification of surface water such as lakes, reservoirs, rivers, etc. In some parks or communities, not only the water quality is purified, but also the landscape is beautified. [0003] Ecological floating islands have ...
