[0037] In a specific embodiment, the ecological planting bed 400 provided in the present application includes a planting bed body 410 and a plurality of blind tubes 440; the planting bed body 410 is a rectangular cube structure with an upper opening, which can adopt a geotechnical structure or a support plus a waterproof cloth structure. The inner cavity of the planting bed body 410 is filled with a matrix layer 450, and the matrix layer 450 includes pebbles or volcanic rocks, etc. The remaining space of the planting bed body 410 is filled with the matrix to a preset height. In other embodiments, the specific form of the matrix layer 450 can be set as needed, which will not be repeated here. A plurality of blind tubes 440 are provided at the bottom of the planting bed body 410, and all the blind tubes 440 are arranged along the horizontal direction of the planting bed body 410 and extend in the longitudinal direction. The blind tube 440 has a through hole that runs through along the length direction to facilitate drainage of the water body. The water inlet assembly 420 and the water outlet assembly 430 are respectively arranged opposite to each other at the longitudinal ends of the planting bed 410, wherein the water inlet assembly 420 is located above the planting bed 410, and the water outlet assembly 430 is located at the bottom wall of the planting bed 410. Preferably, the blind pipe 440 extends longitudinally to facilitate the circulation of water at the bottom of the planting bed 410, and the blind pipe 440 is arranged at intervals in the transverse direction on the bottom wall of the planting bed 410, such as being fixed by threaded fasteners, and in other embodiments, it can also be fixed by welding or other methods, and can be arranged as needed.
[0038] Compared with the prior art, the ecological planting bed 400 provided in the embodiment of the present application has the following technical effects:
[0039] A water inlet assembly 420 and a water outlet assembly 430 are respectively provided at the longitudinal ends of the planting bed 410. A plurality of blind pipes 440 are provided on the bottom wall of the planting bed 410. The blind pipes 440 are arranged longitudinally to divert the water of the water inlet assembly 420 to the water outlet assembly 430, so as to facilitate the discharge of water from the bottom of the planting bed 410, improve the water flow and drainage capacity at the bottom of the planting bed, facilitate microorganisms to obtain sufficient oxygen, promote reproduction metabolism and purify water quality.
[0040] In this embodiment, in order to further facilitate the flow of water, the bottom wall of the planting bed 410 is inclined in the longitudinal direction, the water inlet assembly 420 is located at the high position of the bottom wall of the planting bed 410, and the water outlet assembly 430 is located at the low position of the bottom wall of the planting bed 410. That is, the bottom of the planting bed 410 is provided with an inclination angle with the horizontal plane, which facilitates the flow of water from high to low in the longitudinal direction, improves the flow rate of water, realizes rapid drainage of the planting bed 410, and is conducive to the microorganisms to obtain sufficient oxygen, promote reproduction metabolism and purify water quality.
[0041] In a preferred embodiment, the blind pipe 440 is a plastic blind ditch, which is a composite geodetic drainage body (GDS), also known as a three-dimensional drainage board, which is a three-dimensional porous material formed by heating and melting a thermoplastic synthetic resin, extruding fiber filaments through a nozzle, and welding the joints. The cross section of the blind pipe 440 can be a circular or rectangular structure. It can be understood that the blind pipe 440 can be smooth and pressure-resistant, and the plastic blind ditch has extremely high surface water permeability and internal water permeability, as well as excellent pressure resistance and deformation adaptability.
[0042] At the same time, a grating plate 460 is provided at one end of the planting bed 410 close to the water inlet assembly 420, and the two ends of the grating plate 460 in the length direction are respectively connected to the lateral side walls of the planting bed 410, and the grating plate 460, the lateral side walls of the planting bed 410 and the longitudinal end walls form a water pretreatment area 470, and the water body is pretreated at the front end. Preferably, the water pretreatment area 470 is filled with biochemical balls 480 to add pre-cultured microorganisms, so as to promote the rapid formation of a microbial ecosystem in the ecological planting bed 400 and save time for cultivating microorganisms. In this embodiment, the incoming water body can be pretreated, for example, biochemical balls 480 containing microorganisms such as nitrifying bacteria are placed, which can accelerate the speed of cultivating microbial ecosystems such as nitrifying bacteria in the ecological planting bed 400, thereby quickly purifying the water quality. Specifically, the water inlet assembly 420 is arranged above the planting bed 410 and is arranged opposite to the water pretreatment area 470.
[0043] like Figure 5-6 As shown, Figure 5 A schematic diagram of the structure of a water outlet assembly 430 provided in an embodiment of the present application; Figure 6 for Figure 5 Based on the above embodiments, the water outlet component 430 is a siphon structure, and the water outlet component 430 includes:
[0044] The first sleeve 431 is fixed on the bottom wall of the planting bed 410. The top of the first sleeve 431 is a closed structure. The bottom of the first sleeve 431 has a siphon inlet 4311, which is connected to the inner cavity of the planting bed 410.
[0045] The drainage pipe 432 is sleeved in the first sleeve 431 , and a gap is provided between the top water inlet 4321 of the drainage pipe 432 and the top wall of the first sleeve 431 ; the bottom water outlet 4322 of the drainage pipe 432 is arranged through the bottom wall of the planting bed 410 .
[0046] The outer diameter of the drain pipe 432 is smaller than the inner diameter of the first sleeve 431, so that a gap is formed between the outer wall of the drain pipe 432 and the inner wall of the first sleeve 431 for storing water. A gap is provided between the top water inlet 4321 of the drain pipe 432 and the top wall of the inner cavity of the first sleeve 431, and the bottom water outlet 4322 of the drain pipe 432 penetrates the bottom wall of the planting bed 410 to discharge clean water from the planting bed 410. The drain pipe 432 is configured to be L-shaped to facilitate vacuum maintenance.
[0047] The water outlet assembly 430 further includes a second sleeve 433, which is sleeved on the outside of the first sleeve 431, and the inner diameter of the second sleeve 433 is larger than the outer diameter of the first sleeve 431; the second sleeve 433 is provided with filter mesh holes at a preset distance from bottom to top to filter the water entering the first sleeve 431. Preferably, the circumferential side wall of the second sleeve 433 is fully covered with filter mesh holes.
[0048] Specifically, a plurality of support frames 434 are disposed on the bottom wall of the first sleeve 431 . The support frames 434 are spaced apart along the circumference of the bottom wall of the first sleeve 431 , and a siphon liquid inlet 4311 is formed between adjacent support frames 434 and the bottom wall of the first sleeve 431 .
[0049] When the water level reaches the top water inlet 4321 of the drain pipe 432, negative pressure is formed to attract water to continuously and rapidly flow out of the inner cavity of the planting bed 410 from the top water inlet 4321 of the drain pipe 432 until the liquid level of the planting bed 410 drops to the upper surface of the liquid inlet 4311. The negative pressure effect disappears and the siphon effect stops, thereby achieving rapid discharge of liquid from the planting bed 410 without any additional power, which is economical and environmentally friendly.
[0050] The specific working process is as follows: the aquaculture sewage is pre-treated and flows into one longitudinal end of the planting bed 410 from the water inlet assembly 420, and the water flows to the other longitudinal end of the planting bed 410 through the matrix gap and the blind pipe 440, and the water level gradually rises; the water enters the gap cavity between the second sleeve 433 and the first sleeve 431 through the pores of the second sleeve 433, and flows into the gap cavity between the first sleeve 431 and the drain pipe 432 from the liquid inlet 4311 at the three support frames 434 of the first sleeve 431 at the bottom, and as the water level gradually rises to the drain pipe 4 32, and gradually discharge the air between the top water inlet 4321 and the top wall of the inner cavity of the first sleeve 431, forming a siphon to cause the water to flow out continuously and quickly, and then be discharged from the planting bed 410 through the drain pipe 432; when the water level drops to the upper end of the three support frames 434 of the first sleeve 431, the siphon stops, the drainage stops, and the matrix in the ecological planting bed 400 is fully exposed to the air, so that nitrifying bacteria and other microorganisms can obtain sufficient oxygen, thereby intermittently collecting water and draining water, which is conducive to the reproduction and metabolism of microorganisms to purify water quality. Preferably, a grid plate 460 is set on the planting bed 410 near the side of the water inlet component 420 to form a water pretreatment area 470, which can pre-treat the incoming water. For example, a biochemical ball 480 containing nitrifying bacteria and other microorganisms is placed in the planting bed 400 to accelerate the speed of cultivating nitrifying bacteria and other microbial ecosystems, thereby quickly purifying the water quality.
[0051] The above-mentioned ecological planting bed 400 realizes rapid drainage of the matrix layer 450 by setting a porous blind pipe 440 that is pressure-resistant and conducive to water flow, which is beneficial for microorganisms to obtain sufficient oxygen, promote reproduction and metabolism, and purify water quality; a front-end pretreatment system is set up for the ecological planting bed 400 to add pre-cultivated microorganisms, so as to prompt the ecological planting bed 400 to quickly form a microbial ecosystem and save time; a siphon device is set up to achieve non-powered rapid drainage.
[0052] The present application also provides a fish-vegetable symbiotic system including the above-mentioned ecological planting bed 400. Since the fish-vegetable symbiotic system adopts the ecological planting bed 400 in the above-mentioned embodiment, please refer to the above-mentioned embodiment for the beneficial effects of the fish-vegetable symbiotic system.
