Problems solved by technology

The ecological floating bed can purify the nitrogen and phosphorus in the water body and other nutrients that cause the excessive growth of algae, and has a certain helpful effect on the control of eutrophication in the water body. However, the current ecological floating bed technology mainly relies on the absorption and extraction of floating bed plants to purify the water quality, and the extraction efficiency of nitrogen and phosphorus is very high. Limited, also difficult to inhibit the growth of algae
For example, the utility model patent No. 201620290281.3 discloses an ecological floating bed and an ecological floating bed system. The ecological floating bed combines the adsorption of biochar and the absorption of pollutants by plants to achieve rapid water purification and efficient treatment. Pollution effect, but still unable to inhibit the growth of algae

Description

technical field [0001] The invention relates to the fields of water pollution control and water body ecological restoration, in particular to an algae-inhibiting ecological floating bed. Background technique [0002] Ecological floating bed is a kind of water ecological restoration technology derived from modern agronomic soilless planting technology. It is also commonly called ecological floating island, biological floating bed, artificial floating bed, artificial floating island or biological floating island. In recent years, with the comprehensive advancement of my country's water pollution prevention and control work, this ecological restoration technology known as "water garden" has been widely used in many areas of our country. As far as engineering measures are concerned, the main difference between the ecological floating bed and natural plant purification is that the ecological floating bed uses light materials to fix the aquatic plants and float on the water surfac...
