Biological combined floating bed for establishing ecosystem and research method

Abstract

The invention relates to the technical field of ecosystems, and more particularly relates to a biological combined floating bed for establishing an ecosystem and a research method. The biological combined floating bed includes a floating window and a caisson, the floating window is a square frame surrounded by PVC pipes, four corner points of the floating window are provided with final-planting baskets, and emergent aquatic plants are planted in the final-planting baskets; corncobs are suspended by nylon ropes at the floating window; the caisson is a coverless cube assembled by organic glass,and through holes are evenly arranged in the side walls of the caisson; a plurality of flower pots are arranged inside the caisson, and submerged plants are arranged in the flower pots; and the bottomsurface of the caisson is composed of two pieces of organic glass, and the left and right sides of the caisson are provided with U-shaped plates and control rods. Through synergic effect of the emergent aquatic plants, the corncobs and the submerged plants, nitrification and denitrification reactions are carried out at the same time, so that the floating bed can continuously stably provide beneficial bacterium species and purify a water body.

Description

technical field [0001] The invention relates to the technical field of ecological systems, and more specifically relates to a biologically combined floating bed for establishing an ecological system and a research method. Background technique [0002] The reduction and control of total nitrogen, especially the control of total nitrogen in lakes and urban rivers, and the resolution of low-carbon and high-nitrogen rivers are crucial to improving water quality. [0003] The main problem of the current traditional ecological floating bed is: only relying on a small amount of plant roots under water to absorb nitrogen and phosphorus, and the direct transformation of plants, these are not enough to exert large-scale nitrification. However, the contribution of microbial degradation, absorption, and removal of nitrogen and phosphorus pollutants is much greater than that of plants. In the traditional ecological floating bed, these microorganisms are difficult to form the main force ...

Problems solved by technology

[0003] The main problem of the current traditional ecological floating bed is: only relying on a small amount of plant roots to absorb nitrogen and phosphorus, and the direct transformation of plants, these are not enough to exert large-scale nitrification

In the traditional ecological floating bed, these microorganisms are difficult to form the main force of degrading pollutants, and must rely on other processes to form a sustainable localized water ecosystem, so the traditional ecological floating bed technology is not effective in denitrification

The traditional ecological floating bed is not sustainable, because there is no mature and effective submerged plant transplantation process, it cannot continue to work on the water body after the floating bed is removed, and the localized water ecosystem has not been established, so it is not sustainable
