Ecologically adjustable fish reef ecological floating bed device

Abstract

The invention provides an ecologically adjustable fish reef ecological floating bed device. The device comprises a floating bed frame, a plurality of fish reef module units and aquatic plants, wherein each fish reef module unit is connected with one another and fixed by the floating bed frame and comprises a grid and an organism ceramsite layer, a fish reef channel layer and a packing layer whichare arranged from top to bottom sequentially and are separated from one another by interlayers; the grids surround around the organism ceramsite layers, the fish reef channel layers and the packing layers and the bottoms of the packing layers respectively; fish reef passages are respectively opened around the fish reef channel layers; holes are opened at the position, corresponding to openings ofthe fish reef passages, of the grids to make the fish reef channel layers communicate with outside; and the aquatic plants are arranged on the organism ceramsite layers. The device can ensure the normal growth and prevent the overgrowth of the aquatic plants at the same time; and meanwhile, a simple food chain of 'organisms-planktons-fishes' is formed inside the device to improve the purifying capacity of water of the device.

Description

technical field [0001] The invention belongs to the field of water pollution treatment and prevention, in particular to an ecologically adjustable fish reef ecological floating bed device. Background technique [0002] Ecological floating beds, also known as artificial floating beds, artificial floating islands, etc., have been widely used in pollution control of polluted rivers, lakes, and reservoirs in recent years because of their functions such as water treatment, landscape improvement, and biological living space creation. The purification mechanism of the ecological floating bed is to absorb, absorb, and intercept nutrients such as nitrogen and phosphorus in the water body through the strong root system of the plants on the floating bed, and remove them from the water body in the form of harvesting plants, so as to achieve the purpose of purifying the water quality. Existing ecological floating beds are generally composed of four parts, i.e. floating bed frame, plant f...

AI Technical Summary

Problems solved by technology

Although the existing technology can realize the purification ability of the ecological floating bed, because the roots of the floating bed plants are exposed in the water, they are easily swallowed by fish in the water, thereby affecting the normal growth of the aquatic plants and destroying the purification effect of the ecological floating bed; and At present, the existing ecological floating beds only rely on the adsorption and absorption of aquatic plants and microorganisms to degrade the pollutants in the water body. The mechanism of action is single, the treatment effect is not very ideal, and there are shortcomings such as damage to plant roots and limited metabolic activities of microorganisms. However, the treatment effect on seriously polluted or eutrophic rivers and lakes is very limited, and it has defects such as a single water body purification mechanism.
