Background technique

In recent years, rivers, lakes, reservoirs, ponds and other water bodies have been polluted by the environment, resulting in eutrophication of water bodies and destroying the ecological balance of water bodies. At present, the application of ecological floating islands in water pollution control is attracting more and more attention. Ecological floating islands use the plants cultivated on them to remove pollutants such as nitrogen and phosphorus in polluted water bodies, inhibit the excessive growth of algae in water bodies, and at the same time It can beautify the water body landscape, and has the advantages of no need to occupy land, low cost and good restoration effect.

At present, the existing ecological floating islands still have the following problems: (1) Limited buoyancy: The existing ecological floating islands generally use foamed plastic or recycled plastic as the basic material. Although the production cost is relatively low, the buoyancy is limited and it is easy to break But floating on the water, it is difficult to degrade and cause secondary pollution; (2) Floating island plants are single: Floating island plants are an important part of the ecological floating island. However, the existing ecological floating island plant configuration is difficult to take into account the two major functions of landscape and ecology. In addition, due to the limited buoyancy, it is impossible to plant large plants, and most of the floating island plants cannot survive the winter, especially in winter when the weather is relatively cold. In cold northern regions, floating island plants need to be replanted in the second spring, which not only affects the landscape effect, but also increases maintenance costs; (3) The structure is not stable: traditional floating islands are usually connected by ropes, which is time-consuming and easy to fall apart. The ability to resist wind and waves is poor, and it is difficult to resist extreme winds, heavy rains and heavy waves, and the floating island material polyethylene is easy to oxidize and decompose, thereby shortening its service life.

Then, put the assembled floating island into the design position on the water surface, and choose a suitable fixing method for fixing, such as inserting rod type, anchoring type or revetment pulling type, etc. Then, plant according to the plant type, specification and location selected in the design, and an auxiliary springboard can be used to facilitate the staff to go to the island for planting. Generally, inspections are performed every 2 weeks after planting. When dead seedlings or burning seedlings appear, they need to be replenished or adjusted appropriately. Plants that grow too fast need to be pruned in time. When planting vegetables, they need to be harvested during the harvest season. In case of heavy rain, typhoon and other severe weather conditions, it is necessary to do reinforcement and protection in advance. After the severe weather, it is necessary to check in time and deal with problems found in time.
