Plant composition for efficiently removing nitrogen and phosphorus

Abstract

The invention provides a plant composition for efficiently removing nitrogen and phosphorus. The plant composition for efficiently removing nitrogen and phosphorus comprises a circular floating bed, wherein a mounting groove is formed in the top of the circular floating bed, and a buoyancy ring is fixedly connected to the outer side of the bottom of the circular floating bed; and an emergent planting basket, wherein the emergent planting basket is arranged on the circular floating bed, a plurality of water permeable holes are formed in the two sides of the surface of the emergent planting basket, connecting rings are fixedly connected to the tops of the two sides of the emergent planting basket, fixing grooves are formed in the tops of the connecting rings, fixing bolts are arranged in theconnecting rings, and positioning grooves are formed in the bottoms of the inner walls of the mounting grooves. The plant composition for efficiently removing nitrogen and phosphorus has the advantages of phytoremediation of the water body with high nitrogen and phosphorus content, economy and environmental protection, removal of nitrogen and phosphorus in the eutrophic water body by the plant composition is significantly higher than removal of nitrogen and phosphorus in the single plant group, the plant group can significantly improve the pH value and dissolved oxygen of the water body, andthe EC value can be reduced.

Description

technical field

[0001] The invention relates to the technical field of sewage purification treatment, in particular to a plant composition for efficiently removing nitrogen and phosphorus. Background technique

[0002] Eutrophication refers to the fact that the water body is rich in N nutrients and P nutrients. The combination of N and P nutrients changes the nutrient structure, biological community composition and biochemical cycle of the water ecosystem, resulting in the increase of algae and fish species. Decrease, the process of continuous deterioration of water quality.

[0003] The eutrophication of water bodies caused by human activities threatens the global water ecosystem. With the serious water pollution, many technologies to solve water pollution have emerged. A large number of practices have proved that phytoremediation is the most economical and convenient way to deal with water pollution. Among them, The plant floating bed composed of emergent plants, submerge...
