Description

A fish and vegetable symbiosis system

technical field

The invention relates to the field of agriculture, in particular to an aquaponics system.

Background technique

Fish and vegetable symbiosis is a new type of compound farming system. It combines aquaculture and hydroponics, two completely different farming techniques, through ingenious ecological design, to achieve scientific synergy and symbiosis, so as to realize fish farming without changing water. There is no water quality concern, and the ecological symbiosis effect of growing vegetables normally without fertilization. In traditional aquaculture, with the accumulation of fish excrement, the ammonia nitrogen in the water body increases, and the toxicity gradually increases. In the fish and vegetable symbiosis system, the aquaculture water is transported to the hydroponic cultivation system, and the ammonia nitrogen in the water is decomposed into nitrite by bacteria and then decomposed into nitrate by nitrifying bacteria. Nitrate can be directly absorbed and utilized by plants as nutrients . Aquaponics allows animals, plants, and microorganisms to achieve a harmonious ecological balance. It is a sustainable, circular, zero-emission, low-carbon production model, and it is the most effective way to effectively solve the agricultural ecological crisis.

Since 1997, Dr. James Rakocy of the University of the Virgin Islands and his colleagues have developed a large-scale aquaponics system based on deep water cultivation. Since then, many universities around the world have gradually carried out related technical research to explore the technical methods of large-scale aquaponics agricultural production. The Food and Agriculture Organization of the United Nations also recommends the small-scale aquaponics system as a sustainable agricultural model to the world. In recent years, large-scale aquaponics systems have gradually been put into production around the world, and indoor aquaponics factories have also begun to appear. Currently, the entire aquaponic home gardening and farming industry is developing rapidly.

In the existing fish and vegetable symbiosis system, the water pump pumps the fish manure and residual bait in the fish pond to the planting bed, and the ceramsite on the planting bed parasites nitrifying bacteria, which decomposes the fish manure and residual bait into nutrients that can be absorbed by plants. After the fish pond water is intercepted and filtered by ceramsite, and the nutrients in it are absorbed by the plants, the clean pool water flows back to the fish pond through the siphon device.

The currently public fish and vegetable symbiosis system has the following disadvantages: 1. The ratio of fish and vegetables must be strictly controlled within a certain ratio range. If there is less fish and vegetables, the nutrition will be insufficient. It is quite difficult; 2. Generally, in about six months, the gaps in the filter material (ceramic or stone) of the planting bed will be blocked by fish feces, and a saturated state will appear, which will affect the filtering effect and require a lot of manual intervention; 3. Large area A large amount of filter material is required for promotion, the construction cost is high, and the construction period is long, which is not conducive to commercialization; and 4. Once the planting bed using a large amount of filter material is damaged and leaks, the filter material must be moved, and maintenance is very troublesome.

Contents of the invention

The technical problem to be solved by the present invention is to provide a new type of fish and vegetable symbiosis system, which has a simple structure, many types of planting, high efficiency, good water quality, good energy saving effect, convenient maintenance, and low production and operation costs and maintenance costs.

The invention provides a fish and vegetable symbiosis system. The system includes: a fish pond; a fish pond nitrification bed capable of circulating with the liquid in the fish pond, and a microfiltration machine is arranged on the fish pond nitrification bed; a nutrient solution pool; A septic nitrification bed in which the liquid in the pool is circulated; the liquid separated by the microfilter flows into the fish pond nitrification bed, and the separated dirt is transported to the septic nitrification bed by the sewage pump arranged on the microfilter; and a planting bed, the nutrient solution in the nutrient solution pool is transported to the planting bed.

In one embodiment, the fish pond is provided with a sewage suction pump that sucks the liquid in the fish pond to the microfilter; the fish pond nitrification bed is provided with a siphon device, and the fish pond The liquid on the nitrification bed is returned to the aquarium.

In one embodiment, the nutrient solution pool is provided with a nutrient solution pool circulating pump that sucks the liquid in the nutrient solution pool to the septic nitrification bed; the septic nitrification bed is provided with a siphon device, The liquid on the septic nitrification bed is returned to the nutrient solution pool.

In one embodiment, the nutrient solution pool is provided with a nutrient solution supply pump, which transports the operating solution to the planting bed through pipelines.

In one embodiment, the number of the planting beds is not less than 2.

In one embodiment, the fish pond nitrification bed and/or the septic nitrification bed are filled with ceramsite or river bed stones and planted with plants.

The novel aquaponics system provided by the present invention has the following advantages:

1. Separate most of the fish feces for nitrification treatment separately, and isolate it from the nitrification filtration system of the fish pond, so as to solve the problem that the fish and vegetable ratio is easily out of balance and cause the system to collapse.

2. The separated fish feces are septically treated with a nitrification bed to obtain the nutrient solution required for plant growth; the nutrient solution is transported to each hydroponic planting bed through the liquid supply system.

3. The new aquaponics system of the present invention discards a large number of filter materials, and only the nitrification bed uses filter materials, thereby greatly reducing the construction cost and shortening the construction period.

4. The novel aquaponics system of the present invention is easy to construct, convenient to manage, low in maintenance cost, and suitable for large-scale commercialization.

During work, the sewage suction pump 2 sends the liquid in the fish pond 1 containing fish feces and residual bait to the microfilter 4, and the separated dirt is sent to the septic nitrification bed 5 through the sewage pump arranged on the microfilter 4, And the liquid that separates from the microfilter 4 and contains very little fish excrement and residual bait flows into the fish pond nitrification bed 3 . Plants are planted on the nitrification bed 3 of the fish pond, and the dirt in the pool water is decomposed into the nutrients of the plants and absorbed by the plants. The clean pond water after plant absorbs nutrient and ceramsite filter, flows back to fishpond 1 through siphon device.

The dirt that is sent to the septic nitrification bed 5 by the sewage pump mainly contains fish excrement and residual bait, and contains a small amount of liquid simultaneously, and this liquid is transported to the nutrient solution pool 6 by the siphon device on the septic nitrification bed 5; Residual bait remains on the septic nitrification bed 5. The nutrient solution circulation pump 7 pumps the liquid in the nutrient solution pool back to the septic nitrification bed 5, and forms a tidal circulation through the siphon device on the septic nitrification bed 5, so that fish feces and residual bait are decomposed in the septic nitrification bed 5. Plant nutrients are dissolved in water to form a plant nutrient solution. The nutrient solution supply pump 8 sends the nutrient solution to the planting bed 9 through the delivery pipeline.
