Problems solved by technology

The disadvantage is that the materials used in the floating shelf have the possibility of secondary pollution, and the effect of improving the water quality is not obvious only by the action of the root system of the plants in summer
[0007] The structure of the ecological floating bed is too complicated, and although three layers of aquatic plants, aquatic animals, and microorganisms are set up to improve water quality, these three layers work independently without any connection and connection, and the water quality improvement effect needs to be further improved

Embodiment 1

[0031] Embodiment 1 Ecological floating bed

[0032] Such as figure 1 As shown, an ecological floating bed in this embodiment includes a floating bed frame 1, a plurality of first-layer boxes 2 are fixed below the floating bed frame 1, and connecting rods 4 are provided at the bottom of each first-layer box 2, adjacent to each other. A second layer of casing 3 is suspended on the connecting rods 4 of the two first layer of casings 2 . The floating bed frame 1, the first layer of casing 2 and the second layer of casing 3 are all made of carbonized bamboo.

[0033]The first layer of box 2 is filled with plant planting substrates, which include aerated concrete fragments, rotten wood and dead leaves (which can be mixed or laid sequentially), carbonized bamboo waste particles and fine limestone. Gravel (the two can be mixed, or they can be laid sequentially).

[0034] The first layer of box body 2 is used for planting aquatic or terrestrial plants with sewage purification funct...

Embodiment 2

[0041] The water quality improvement effect test of embodiment 2 different planting matrix compositions

[0042] Fill the first layer of boxes with planting substrates of different compositions, and plant Lythrum salicaria L., Typha davidiana (Kronf.) Hand.-Mazz., and Canna indica L. , Spathiphyllum kochii, and Phnom Penh Chlorophytum; after planting, put the ecological floating bed into a test water body with an indoor temperature of 22°C, test the COD content of the water body after 10 days, and compare the effects of different ecological floating beds on the water test body The results of water quality improvement are shown in Table 1.

[0043] Experimental group 1: 35% aerated concrete fragments, 30% carbonized bamboo waste particles, 10% dead wood, 5% dead leaves, 20% limestone fine gravel;

[0044] Experimental group 2: 30% aerated concrete fragments, 25% carbonized bamboo waste particles, 15% dead wood, 5% dead leaves, 25% limestone fine gravel;

Abstract

The invention discloses an ecological floating bed. The ecological floating bed comprises a floating bed frame, and a first box body layer fixed below the floating bed frame, wherein a second box body layer with an opened top surface is hung below the first box body layer; a plurality of through holes are formed in both bottom and sidewall of the first box body layer; a plant planting substrate is filled in the first box body layer; broken aerated concrete is filled in the second box body layer; the plant planting substrate comprises the broken aerated concrete, a plant fertilizer, waste carbonized bamboo particles, and limestone fine gravels, which are filled in sequence. According to the ecological floating bed, the planting substrate in the first box body, and humus produced by the planting substrate consumed in the production of a plant and microorganisms can expose from the through holes and then be scattered into the second box body, thus the growth of a microbial film can be promoted, and a certain food and water environment is provided for benthonic mollusk, fish and other aquatic animals and induces the breeding; intelligent bionic aquatic plants are also fixed to the floating bed frame, which can perform aeration and oxygenation on water mass to increase the oxygen content in the water mass.

Description

technical field [0001] The invention relates to a river water body purification device, in particular to an ecological floating bed. Background technique [0002] Eutrophication refers to the large amount of nutrients such as nitrogen and phosphorus required by organisms entering slow-flowing water bodies such as lakes, estuaries, and bays, causing algae and other plankton to multiply rapidly, the dissolved oxygen in the water body decreases, and fish and other organisms die in large numbers. Phenomenon. A large number of dead aquatic organisms are deposited at the bottom of the lake, decomposed by microorganisms, and consume a large amount of dissolved oxygen, causing a sharp decrease in the dissolved oxygen content of the water body, deteriorating the water quality, affecting the survival of fish, and greatly accelerating the eutrophication process of the water body. [0003] It is imperative to improve the water quality of eutrophic water bodies. At present, the water q...
