[0054] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0056] In a specific embodiment, the fish manure treatment equipment 200 provided in the present application includes a vertical flow separation chamber 210, a filter chamber 220 and a collection and fermentation chamber 230; the vertical flow separation chamber 210 has an aquaculture water inlet 211 and an aquaculture water outlet 212, and the aquaculture water inlet 211 is connected to the upper-level processing unit, which is generally aquaculture equipment, such as a breeding barrel with aquatic organisms; the aquaculture water includes fish manure or feed residues, etc., the aquaculture water inlet 211 is preferably arranged at the bottom of the vertical flow separation chamber 210, and the aquaculture water outlet 212 is preferably arranged at the top of the vertical flow separation chamber 210 to increase the vertical flow separation path and improve the filtering effect. A vertical flow separation device 213 is provided in the vertical flow separation chamber 210 to realize vertical flow separation of the aquaculture water.

[0057] The aquaculture water after vertical flow separation enters the filter chamber 220. The filter chamber 220 and the vertical flow separation chamber 210 are arranged in sequence. A filter device 221 is provided in the filter chamber 220 to separate the particulate matter and clean water in the aquaculture water, and the aquaculture water with particulate matter is discharged to the collection and fermentation chamber 230 for collection and fermentation, so as to decompose the organic matter in the aquaculture water and particulate matter, so that the ammonia nitrogen with high toxicity to fish produced in the decomposition of the organic matter can be directly metabolized or secondary metabolized through the life activities of microorganisms under aerobic or anaerobic conditions, so as to fully decompose the particulate matter such as the filter residue, so as to facilitate the subsequent plants to fully utilize the organic impurities.

[0058] Among them, the vertical flow separation chamber 210, the filtration chamber 220 and the collection and fermentation chamber 230 are an integrated machine. The vertical flow separation chamber 210 and the filtration chamber 220 are located on the upper layer, and the collection and fermentation chamber 230 is located on the lower layer. In this way, several processing units are integrated into the same device, simplifying the device structure and reducing the floor space. Adjacent units can flow naturally under the action of gravity without the need for additional pumping equipment, further reducing the cost of the device.

[0059] Compared with the prior art, the fish manure treatment device 200 provided in the embodiment of the present application has the following technical effects:

[0060] The aquaculture water is vertically separated by the vertical flow separation device 213 in the vertical flow separation chamber 210, and the filtered aquaculture water enters the filter chamber 220 for filtering again to separate the particulate matter and clean water in the aquaculture water, collect and ferment the filtered particulate matter, decompose the harmful substances in the aquaculture wastewater and the particulate matter, discharge the harmful gases, and fully release the nutrients in the particulate matter into the water body to meet the nutritional needs of the aquaculture plants, make full use of the aquaculture wastewater, reduce the supplementation of additional nutrient reagents, and reduce the aquaculture cost.

[0061] The vertical flow separation device 213 includes a first vertical sleeve 2131, a second vertical sleeve 2132 and a horizontal partition 2133; the top of the first vertical sleeve 2131 is an open structure, and the bottom of the first vertical sleeve 2131 extends to communicate with the aquaculture water inlet 211. It can be understood that the bottom opening of the first vertical sleeve 2131 is sealed and connected to the aquaculture water inlet 211 of the vertical flow separation chamber 210, and the first vertical sleeve 2131 is flush with the wall of the vertical flow separation chamber 210 or extends to the outside of the vertical flow separation chamber 210 to facilitate connection with the aquaculture water discharge pipeline of the previous level, and can be set as needed. The second vertical sleeve 2132 is sleeved on the outside of the first vertical sleeve 2131, and a horizontal spacing is provided between the second vertical sleeve 2132 and the first vertical sleeve 2131, that is, the inner diameter of the second vertical sleeve 2132 is larger than the outer diameter of the first vertical sleeve 2131, and the bottom of the second vertical sleeve 2132 is an open structure and is connected to the inner cavity of the vertical flow separation chamber 210; the top and bottom of the second vertical sleeve 2132 are both open structures. The horizontal partition 2133 is fixedly mounted on the outside of the second vertical sleeve 2132. Preferably, the horizontal partition 2133 and the second vertical sleeve 2132 are sealed and connected. The circumferential edge of the horizontal partition 2133 is fixed and sealed to the inner wall of the vertical flow separation chamber 210, and the vertical flow separation chamber 210 is divided into a top water outlet chamber 214 and a bottom water inlet chamber 215. It can be understood that the aquaculture water inlet 211 is located in the bottom water inlet chamber 215, and the aquaculture water outlet 212 is located in the top water outlet chamber 214, so as to realize the vertical flow separation of aquaculture sewage from bottom to top. Among them, a plurality of overflow holes 21331 are provided on the horizontal partition 2133, and the overflow holes 21331 penetrate the horizontal partition 2133 along the wall thickness direction, so that the aquaculture water in the bottom water inlet chamber 215 can overflow to the top water outlet chamber 214, and discharge the vertical flow separation chamber 210 from the aquaculture water outlet 212 above the top water outlet chamber 214, and enter the filter chamber 220. The vertical flow separation device 213 and the vertical flow separation chamber 210 form an "S"-shaped flow path for the aquaculture sewage, which fully separates the aquaculture sewage vertically and improves the filtering effect.

[0062] The specific flow path of the aquaculture sewage in the vertical flow separation chamber 210 is as follows: the aquaculture water enters the bottom of the first vertical sleeve 2131 through the aquaculture water inlet 211, and spreads from bottom to top in the first vertical sleeve 2131, and then flows out from the top opening of the first vertical sleeve 2131, and flows from top to bottom between the outer wall of the first vertical sleeve 2131 and the inner wall of the second vertical sleeve 2132 under the action of gravity, and flows from the bottom of the second vertical sleeve 2132 into the bottom water inlet chamber 215, and the water level of the aquaculture sewage in the bottom water inlet chamber 215 gradually rises until it contacts the bottom wall of the horizontal partition 2133. At this time, the water flow speed slows down and spreads from the overflow hole 21331 to the top water outlet chamber 214. At this time, the water level continues to spread upward until the water level rises to the aquaculture water outlet 212 and flows out of the vertical flow separation chamber 210 and enters the filter chamber 220; the above-mentioned flow process, by setting the first vertical sleeve 2131, the second vertical sleeve 2132 and the horizontal partition 2133, realizes the circuitous reciprocating rise of the aquaculture water and performs vertical separation. Large particles are gathered in the bottom water inlet chamber 215, and the clean water above gradually spreads to the top water outlet chamber 214 through the horizontal partition 2133, thereby realizing the filtration separation of particles and aquaculture sewage.

[0063] In another embodiment, the vertical flow separation device 213 also includes a third vertical sleeve 2134, which is fixed to the upper surface of the horizontal partition 2133 and is sleeved on the outside of the second vertical sleeve 2132. Each overflow hole 21331 is located between the third vertical sleeve 2134 and the second vertical sleeve 2132. The third vertical sleeve 2134 is sleeved on the outside of the second vertical sleeve 2132 to form an annular cavity with the second vertical sleeve 2132. The overflow hole 21331 is located in the annular cavity so that vertical overflow can be further achieved through the third vertical sleeve 2134, thereby further improving the filtering effect. Specifically, a plurality of saw teeth 21341 are provided on the top circumferential edge of the third vertical sleeve 2134, and the particulate matter in the aquaculture sewage is blocked and filtered again by the saw teeth 21341. At the same time, the water flow rate can be further slowed down, so that the clearer water in the upper layer of the aquaculture sewage flows into the next-level filter chamber 220 for filtration.

[0064] It can be understood that in order to prevent the aquaculture sewage from backflowing into the second vertical sleeve 2132, the second vertical sleeve 2132 is higher than the height of the third vertical sleeve 2134, so that the water flow higher than the third vertical sleeve 2134 flows outward through the third vertical sleeve 2134 and can flow to the next-level treatment unit through the aquaculture water outlet 212; the height of the aquaculture water outlet 212 is lower than the height of the third vertical sleeve 2134, and the aquaculture sewage is gathered in the cavity formed by the horizontal partition 2133 outside the third vertical sleeve 2134 and the vertical flow separation chamber 210, and is discharged out of the vertical flow separation chamber 210 when the liquid level rises to the aquaculture water outlet 212.

[0065] Furthermore, in order to slow down the water velocity of aquaculture wastewater, the aquaculture water outlet 212 is a long strip hole, so that the wastewater in the top water outlet chamber 214 can flow out slowly without causing excessive disturbance to the water body and particulate matter at the bottom of the top water outlet chamber 214. The clearer liquid at the upper layer of the top water outlet chamber 214 is preferentially discharged into the next-level filter chamber 220, further improving the filtering effect of the vertical separation chamber.

[0066] In another embodiment, the filtering device 221 comprises:

[0067] The liquid inlet nozzle assembly 2211 has one end connected to the aquaculture water outlet 212 and the other end connected to the filter chamber 220;

[0068] The filter assembly 2212 is located inside the filter chamber 220 and is tilted from top to bottom away from the vertical flow separation chamber 210;

[0069] The filter chamber 220 includes a filter residue collection chamber 2201 and an aquaculture water collection chamber 2202. The filter residue collection chamber 2201 is located at the tail end of the extension direction of the filter component 2212, and the filter residue collection chamber 2201 is connected to the collection and fermentation chamber 230; the aquaculture water collection chamber 2202 is located below the filter component 2212 and is used to collect filtered aquaculture water.

[0070] In order to match the structure of the aquaculture water outlet 212, a liquid inlet nozzle assembly 2211 is provided in the filter device 221. The liquid inlet nozzle assembly 2211 is a closed shell having a set of relatively arranged flat mouth structures; specifically, a rectangular shell, and the opposite side walls of the rectangular shell are provided with flat mouth structures, and the width of the flat mouth structure can be set to 3-15 cm, which can be set as needed. The liquid inlet nozzle assembly 2211 is arranged obliquely downward, so that the incoming aquaculture sewage can flow to the filter assembly 2212 for filtration under the action of gravity.

[0071] The filter component 2212 is located inside the filter chamber 220, tilted downward, and extends away from the vertical flow separation chamber 210. The filter component 2212 can be a filter screen, and the mesh number of the filter screen can be 80-120 meshes, preferably 100 or 120 meshes, to maximize the filtering effect. According to the position of the filter screen, the filter chamber 220 is divided into a filter residue collection chamber 2201 and an aquaculture water collection chamber 2202, wherein the filter residue collection chamber 2201 is located at the tail end of the extension direction of the filter component 2212, collects liquid organic matter containing aquaculture sewage and organic substances such as fish feces that slide down from the filter component 2212, and transports it to the collection and fermentation chamber 230 for collection and fermentation; in order to better collect particulate matter such as fish feces, the filter residue collection chamber 2201 is set to be funnel-shaped, and is inclined from both sides to the middle in the width direction of the filter screen to concentrate particulate matter such as fish feces in the middle of the funnel for easy discharge, and a pipeline connected to the collection and fermentation chamber 230 is arranged at the bottom of the filter residue collection chamber 2201, and a stop valve is arranged on the pipeline to control the on-off of the pipeline.

[0072] The aquaculture water collection chamber 2202 is located below the filter assembly 2212, and collects the filtered aquaculture water and discharges it into the next level processing unit, which can also be achieved by setting a drainage pipeline; the area of ​​the aquaculture water collection chamber 2202 is equal to the positive projection area of ​​the filter assembly 2212 in the horizontal plane, so that the aquaculture sewage filtered by the filter assembly 2212 can be collected in time. Therefore, according to the structure of the filter net, the particles such as fish feces and the filtered aquaculture sewage are collected in the corresponding areas, the device structure is simplified, the internal space structure of the filter chamber 220 is optimized, and the space utilization rate is improved.

[0073] In an optional embodiment, the filter assembly 2212 further includes a high-pressure cleaning assembly 2213, a flushing pump 22131, a high-pressure flushing pipeline 22132 and a high-pressure flushing nozzle 22133 connected in sequence, the high-pressure flushing nozzle 22133 is located below the filter assembly 2212, and is used to flush the filter assembly 2212 from bottom to top; the high-pressure flushing pipeline 22132 is arranged obliquely along the extension direction of the filter assembly 2212, and is arranged in a plurality of rows, and each row of high-pressure flushing pipelines 22132 is respectively provided with a plurality of high-pressure flushing nozzles 22133, which are used to flush the filter net from bottom to top, so that the filter residues such as fish feces on the filter net will not adhere or clog the filter net, and maintain the good filtering performance of the filter net. The flushing water of the high-pressure flushing nozzle 22133 is tap water.

[0074] In order to prevent splashing during high-pressure flushing of the filter screen, a folding side cover 2203 is provided on the side wall of the filter chamber 220, so that the folding side cover 2203 can be closed during high-pressure cleaning to prevent splashing; at the same time, the folding side cover 2203 can be opened to observe the liquid level of the filter residue collection chamber 2201, and the filter screen can be disassembled and cleaned in time, thereby improving convenience.

[0075] In this embodiment, the collecting and fermenting chamber 230 includes a collecting chamber 231 and a fermentation chamber 232 which are arranged in sequence from top to bottom; the collecting chamber 231 is respectively connected to the residue collecting chamber 2201 and the vertical flow separation chamber 210, and a collecting chamber inclined plate 2311 extending along the length direction of the collecting chamber 231 is provided in the collecting chamber 231, and a collecting chamber residue discharge pipeline 2312 is provided on one side of the collecting chamber 231, close to the bottom of the collecting chamber inclined plate 2311, and the collecting chamber residue discharge pipeline 2312 is connected to the fermentation chamber 232.

[0076] It can be understood that the bottom wall of the vertical flow separation chamber 210 is provided with a collecting funnel 216, and the bottom of the collecting funnel 216 is connected to the collecting chamber 231 through a pipeline, and a stop valve is provided on the pipeline to control the on-off of the pipeline; the collecting chamber 231 collects the fish feces and other particles in the vertical flow separation chamber 210 and the filter residue collection chamber 2201 respectively, and precipitates them in the collecting chamber 231; at the same time, the collecting chamber inclined plate 2311 extends along the length direction of the collecting chamber 231 and is inclined, so that the particles can flow along the collecting chamber 231. The collecting chamber inclined plate 2311 gathers to its bottom. In the collecting chamber 231, a collecting chamber filter residue discharge pipeline 2312 is provided at the bottom of the collecting chamber inclined plate 2311 to discharge the precipitated fish feces and other particulate matter into the fermentation chamber 232; a collecting chamber overflow port 2313 is provided at the top of the collecting chamber 231. When the water level of the aquaculture sewage in the collecting chamber 231 rises to the top, the water above the collecting chamber 231 is discharged to the next-level treatment unit through the collecting chamber overflow port 2313.

[0077] In another embodiment, a sewage pump 2321, a sewage self-circulating pipeline 2322 and a return pipeline 2323 are provided in the fermentation chamber 232; one end of the sewage pump 2321 is connected to the bottom end of the inner cavity of the fermentation chamber 232, and the other end is respectively connected to the sewage self-circulating pipeline 2322 and the return pipeline 2323, and the other end of the sewage self-circulating pipeline 2322 is located in the fermentation chamber 232 for oxygen supply; the other end of the return pipeline 2323 is connected to the top water outlet cavity 214.

[0078] It can be understood that one end of the sewage pump 2321 is connected to the bottom of the inner cavity of the fermentation chamber 232 so as to extract the aquaculture sewage at the bottom of the fermentation chamber 232 and supply it to the sewage self-circulation pipeline 2322 and the return pipeline 2323. In order to increase the oxygen content in the fermentation chamber 232, a sewage self-circulation pipeline 2322 is set in the fermentation chamber 232, one end of which is connected to the sewage pump 2321 and the other end is located in the fermentation chamber 232. The sewage pump 2321 pumps the sewage in the fermentation chamber 232 into the sewage self-circulation pipeline 2322, so that the sewage circulates in the fermentation chamber 232, and increases the contact area with the air during the circulation process, so as to increase the dissolved oxygen in the water, which is convenient for aerobic fermentation of particles such as fish feces.

[0079] For the fermented aquaculture sewage, the direction is changed by the reversing valve of the sewage pump 2321, and the sewage self-circulation pipeline 2322 and the return pipeline 2323 are switched to pump the fermented aquaculture sewage back to the top water outlet chamber 214 of the vertical flow separation chamber 210, and continue the top overflow and filtering process of the filter device 221, and treat it again to improve the treatment effect of aquaculture sewage and particulate matter such as fish feces, and fully treat particulate matter such as fish feces, so that large particles are transformed into small particles through vertical falling and fermentation of the filtering device 221, and the organic matter therein is fully decomposed and discharged into the plant planting bed along with the aquaculture sewage to provide the required nutrients for plant growth.

[0080] In order to further increase the oxygen content of the aquaculture sewage in the fermentation chamber 232, a fermentation chamber inclined plate 2324 is also provided in the fermentation chamber 232. The fermentation chamber inclined plate 2324 extends along the length direction of the fermentation chamber 232. The liquid inlet end of the sewage pump 2321 is located at the bottom of the fermentation chamber inclined plate 2324 to continue to lift the aquaculture sewage containing particulate matter and fermented to the top water outlet chamber 214 to continue to treat the particulate matter; on the other side, the discharge end of the sewage self-circulation pipeline 2322 is located at the top of the fermentation chamber inclined plate 2324. At the same time, the spray pipe of the sewage self-circulation pipeline 2322 extends along the width direction of the fermentation chamber inclined plate 2324, and a number of nozzles are arranged on the spray pipe to further increase the contact area between the aquaculture sewage sprayed from the sewage self-circulation pipeline 2322 and the air, thereby increasing the oxygen content in the aquaculture sewage.

[0081] At the same time, the fermentation chamber inclined plate 2324 allows the aquaculture wastewater to converge from top to bottom, and the particulate matter in the aquaculture wastewater can be gathered at the bottom of the fermentation chamber 232, making it easier for the sewage pump 2321 to extract the aquaculture wastewater containing most of the particulate matter, and further perform secondary treatment on the particulate matter, thereby improving the treatment effect of the particulate matter.

[0082] It can be understood that a heating component 2325 is provided in the fermentation chamber 232 to adjust the fermentation temperature in the fermentation chamber 232. Preferably, an interlayer is provided in the side wall of the fermentation chamber 232 in the length direction, and the heating component 2325 is arranged in the interlayer to improve the safety of the heating component 2325. The heating component 2325 can be set to an S-shaped or a meander-shaped heating resistance wire, and by heating the side wall of the fermentation chamber 232, the aquaculture sewage in the fermentation chamber 232 can be evenly heated to achieve uniform heating.

[0083] On the basis of the above embodiments, the vertical flow separation chamber 210, the filtration chamber 220 and the collection and fermentation chamber 230 are an integrated device; the top of the collection and fermentation chamber 230 is provided with an observation port 2301 for observing the liquid level of the aquaculture water.

[0084] The vertical flow separation chamber 210, the filter chamber 220, the collection and fermentation chamber 230 and the control device are integrated into one body, so that it can be used as a separate fish manure treatment equipment 200 and can be mass-produced; compared with the split structure, it occupies a small space, has a compact structure, does not require additional pipes and other connectors, simplifies the device structure, and reduces the device cost. Specifically, an installation cavity 2302 for installing a control device and a pumping device is provided on the side of the collection and fermentation chamber 230. The installation cavity 2302 runs through the width direction of the fish manure treatment equipment 200, and the control device is integrated at the front end of the installation cavity 2302. A pumping device is arranged inside the installation cavity 2302. The pumping device specifically includes a sewage pump 2321 and a flushing pump 22131, so as to further optimize the internal space structure of the equipment, improve space utilization, and improve system safety.

[0085] The specific operation process of the fish manure treatment equipment 200 is as follows: the aquaculture sewage in the aquaculture barrel enters into the first vertical sleeve 2131 through the aquaculture water inlet 211, and spreads upward from bottom to top until the aquaculture sewage rises to the top opening of the first vertical sleeve 2131, and then flows out under the action of gravity, flows from top to bottom along the horizontal interval between the first vertical sleeve 2131 and the second vertical sleeve 2132, and decelerates; since the bottom of the second vertical sleeve 2132 is an open structure and is connected to the vertical flow separation chamber 210, the aquaculture sewage flowing through the bottom of the second vertical sleeve 2132 continues to flow to the bottom of the vertical flow separation chamber 210, and the water flow speed slows down; the aquaculture sewage accumulates at the bottom of the vertical flow separation chamber 210, and as the accumulation proceeds, the water level in the vertical flow separation chamber 210 rises, and when the water level rises to above When the horizontal dividing piece is in the position, the aquaculture sewage enters into the top water outlet chamber 214 through the overflow hole 21331 on the horizontal dividing piece 2133, and is located between the lateral intervals of the third vertical sleeve 2134 and the second vertical sleeve 2132. At this time, the water level continues to rise. When the water level is higher than the top edge of the third vertical sleeve 2134, the aquaculture sewage spreads to the top water outlet chamber 214 outside the third vertical sleeve 2134, and the particles in the aquaculture sewage are filtered through the saw teeth 21341 of the third vertical sleeve 2134, so that the clearer upper layer of water is discharged into the top water outlet chamber 214. At this time, the water level in the top water outlet chamber 214 rises, and the water flow speed is further slowed down; when the water level in the top water outlet chamber 214 rises to the aquaculture water outlet 212, it is discharged into the filter chamber 220 through the aquaculture outlet.

[0086] Aquaculture sewage enters the filter chamber 220 through a liquid inlet nozzle assembly 2211 with a flat mouth structure, is filtered through a filter assembly 2212, and is collected by an aquaculture water collection chamber 2202 located below the filter assembly 2212. The collected aquaculture sewage enters the next-level treatment unit through a pipeline; the liquid organic matter with particles such as fish feces obtained after filtration slides from top to bottom to the filter residue collection chamber 2201 for collection, and when the liquid level in the filter residue collection chamber 2201 reaches a preset height, it is discharged into the collection and fermentation chamber 230 for collection and fermentation.

[0087] The collecting chamber 231 collects and precipitates the aquaculture wastewater containing particles such as fish feces after being filtered by the filtering chamber 220. The aquaculture wastewater moves through the collecting chamber inclined plate 2311, and the particles such as fish feces accumulate at the bottom of the collecting chamber inclined plate 2311. When the liquid level in the collecting chamber 231 reaches a preset height, it is discharged to the next-level treatment unit through the collecting chamber overflow port 2313 at the top of the collecting chamber 231. By opening the collecting chamber filter residue discharge pipeline 2312, the particles such as fish feces in the collecting chamber 231 are discharged into the fermentation chamber 232 along with the aquaculture wastewater for fermentation.

[0088] The aquaculture sewage entering the fermentation chamber 232 also flows obliquely from top to bottom through the fermentation chamber inclined plate 2324, and gathers fish feces and other particles at the bottom of the fermentation chamber inclined plate 2324. The fermentation temperature of the fermentation chamber 232 is adjusted by the heating component 2325 to meet the temperature required for the fermentation of particles. At the same time, the sewage self-circulation is performed at a preset frequency through the sewage pump 2321 and the sewage self-circulation pipeline 2322 to provide oxygen for the fermentation of particles; at the same time, after a certain period of fermentation, the control return pipeline 2323 and the sewage pump 2321 are started to lift the fermented aquaculture sewage back to the top water outlet chamber 214 for collection, and then enter the filter chamber 220, the collection chamber 231 and the fermentation chamber 232 for treatment; it can be lifted 3-5 times in the fermentation step. When the entire fermentation process is completed, the filter residue and other particle residues are discharged through the sewage outlet at the bottom of the fermentation chamber 232 to complete the treatment of the aquaculture sewage and particles.

[0089] The above device can decompose fish feces and particulate matter, so that the nutrients of fish feces and other particulate matter can be decomposed into small particles that can be used by plants. Nitrogen compounds are produced during the decomposition of fish feces. After a series of microbial transformations, ammonia nitrogen will gradually be converted into nitrates, providing an important nitrogen source for plant absorption and utilization. At the same time, the phosphorus contained in fish feces will form phosphates during the fermentation process. The fermentation process will breed a rich microbial community, including bacteria, fungi, etc., which play a key role in material transformation and ecological balance; the humus formed at the same time, as an organic substance, can improve the soil structure, increase the soil's water and fertilizer retention capacity, provide necessary nutrients for plant growth, and promote the sustainable operation of the fish-vegetable symbiotic system. The ammonia nitrogen and phosphorus elements in the aquaculture sewage are converted into nitrates and phosphates that can be absorbed by plants. At the same time, the dissolved oxygen in the aquaculture water increases, and the fish can grow healthily. The treated water body is then used for the plants in the plant cultivation and purification system 4000. The above system makes full use of the ammonia nitrogen and phosphorus elements contained in the aquaculture water, so there is no need to apply the required fertilizers to the plants regularly and quantitatively, and there is no need to invest a lot of labor costs, which reduces the investment cost of hydroponic plant cultivation. Through filtration and fermentation, aquaculture wastewater can be decomposed and released nutrients, which makes it easier for plants in the subsequent ecological planting beds to absorb and utilize the treated nutrients, so as to fully provide the nutrients needed by the plants, reduce or eliminate the need to add additional nutrient reagents, and enable the fish-vegetable symbiotic system to achieve self-sufficiency of nutrients for aquatic organisms and plants, thereby realizing a closed-loop aquaculture water circulation in the fish-vegetable symbiotic system.
