Three-dimensional ecological floating bed

Abstract

The invention relates to a three-dimensional ecological floating bed which comprises an inner frame and an outer frame in one sample plane; the inner frame is fixedly connected with the outer frame through connecting pipes; the inner frame, the outer frame and the connecting pipes are hollow pipelines; flexible net bodies respectively wrap the upper part and the lower part on the periphery of each of the inner frame pipeline and the outer frame pipe between the inner frame and the outer frame to form a bed body for floating plants; a rigid net body lower than the inner frame is fixed and suspended on the inner frame through hooks to form a bed body for emergent plants; the emergent plants are planted on the rigid net body through fixedly placing hollowed-out planting baskets; the hollowed-out planting baskets are suspended on pipelines on the periphery of the outer frame through ropes to form a bed body for submerged plants; a protective net that covers the periphery under the outer frame and the bottom and is capable of isolating bred fishes, shrimps and crabs from the plants in the floating bed is also fixedly placed on the outer frame. The three-dimensional ecological floating bed provided by the invention can simulate a natural planting environment and plant the different levels of plants according to the natural niche of each plant, thereby effectively reducing nitrogen and phosphorus as well as organic matters in a water body, facilitating water body restoration and also having a certain landscape effect.

Description

technical field [0001] The invention relates to the technical field of bioremediation of eutrophication in aquaculture ponds, in particular to a three-dimensional ecological floating bed for planting aquatic plants. Background technique [0002] In the prior art, pond aquaculture adopts a high-density aquaculture method. While increasing the catch per unit water body, due to a large amount of feed input and the accumulation of metabolites of aquaculture objects, the endogenous pollution of aquaculture ponds increases and the water body becomes eutrophic. , the discharge of aquaculture wastewater pollutes the surrounding water bodies of the aquaculture environment, seriously restricting the sustainable development of the freshwater aquaculture industry. [0003] At present, the restoration technology of aquaculture ponds can be generally divided into two categories according to the disposal location: one is the in-situ restoration technology represented by the fish-vegetable ...

Problems solved by technology

Many scholars have also considered plant diversity. When designing ecological floating beds, the layout of floating plants and emergent plants has been considered. However, the plant roots are still at the same level, and the root microbial community does not show multi-level characteristics.

Some introduce biological fillers or artificial aquatic plants into the design of ecological floating beds to provide a good attachment and growth environment for microorganisms and purify sewage through a larger biofilm surface area. Plant roots not only provide habitat for microbes, but also absorb pollutants in water
