System combining aquaculture and soilless agriculture planting

Abstract

The invention relates to a system combining aquaculture and soilless agriculture planting. The system comprises an aquaculture unit, a soilless planting unit and a water processing unit. The aquaculture unit, the soilless planting unit and the water processing unit are connected through water flow pipelines. The aquaculture unit comprises an aquaculture pond, an oxygenation device and a water temperature controller, wherein the oxygenation device and the water temperature controller are connected with the aquaculture pond. The soilless planting unit comprises a soilless planting bed chamber, a plant nutrient controller and a planting chamber carbon dioxide concentration controller, wherein the plant nutrient controller and the planting chamber carbon dioxide concentration controller are connected with the soilless planting bed chamber. The water processing unit comprises a nitrogen processing device, an ultrafiltration membrane filtering device and a sterilization device all of which are sequentially connected. Compared with the prior art, the system overcomes the defects that in the prior art, the water quality processing technology is poor and the carbon diode concentration in a planting chamber is not controlled. The density of cultivation and the density of planting are greatly improved, and resources such as space and energy are utilized to the maximum. The system is implemented without the limits of geographic positions, weather and the quality of lands, and can be implemented at any place.

Description

technical field [0001] The invention belongs to the technical field of aquaculture and agriculture, and in particular relates to a system combining aquaculture and soilless agricultural planting. Background technique [0002] Traditional aquaculture and agriculture belong to different fields. The production site of aquaculture is the water surface, and ponds, reservoirs, lakes, rivers, and oceans are its main production sites; the production site of agriculture is land, and paddy fields and dry fields are its main production sites. These two industries have one thing in common, that is, they both need water, and water is the blood of these two industries and the lifeblood of these two industries. At present, although factory-like aquaculture and agriculture have been developed, the technology of introducing high-tech water treatment, maintaining water quality through artificial reinforcement, and combining the two into a mutually integrated system has not yet appeared.

Problems solved by technology

For example, Chinese Patent No. 90100155 discloses a fish (shrimp) vegetable symbiosis system, through which fish are raised in water, water surface and three-dimensional soilless cultivation of vegetables. Feces collection well, the fish feces and sewage in the collection well are sucked by the sewage pump and poured upwards into the cultivation tank on the top layer, so that the waste water and waste residue produced by breeding are not separated

There are obvious defects in water quality control technology, which is difficult to be practical

[0004] Chinese patent No. 99110087 discloses an aquatic plant and animal ecological circulation breeding system, in which duckweed plants are planted in the aquatic plant tank and circulated with the water in the aquatic animal tank. However, the implementation details of the system structure of this patent are relatively rough, and the waste water Not separated from waste residue, limited to planting aquatic plants

[0005] Chinese Patent No. 200810204130 discloses a photocatalytic-plant synergistic water purification method for fish farming water bodies. A filter tank is designed to discharge solid impurities from cultivation, which is treated with a photocatalytic material containing titanium dioxide and then used to cultivate plants. However, its efficiency is not high. It is mainly used for low-concentration water quality treatment of municipal landscapes, rather than large-scale aquaculture / planting, and the photocatalytic materials containing titanium dioxide used in it are too expensive for large-scale aquaculture / planting promotion

[0006] Chinese patent No. 200880123138 discloses symbiosis equipment for vegetables and fish. In addition to the more conventional breeding and cultivation units, it also includes the use of condensation pipes to collect the water transpired by plants.

[0007] Chinese patent No. 200910037806 discloses a device and implementation method for efficient recycling of aquaculture, including a plant cultivation floating bed, a microbial cultivation middle layer, and a bottom resonance plate. However, the amount of plant cultivation in this patent is limited by the amount that the plant cultivation floating bed can float The area of ​​the water body, the breeding efficiency of its device structure is not high

[0008] Chinese Patent No. 201010103123 discloses a method for removing organic particles and nutrient salts in closed circulation aquaculture water, mainly using non-mainstream agricultural plants with poor economical efficiency such as algae or ryegrass, and the corresponding structure is only suitable for aquaculture water with a daily circulation of 10 double the situation

[0009] Chinese Patent No. 201010138335 discloses a double-layer aquaponics symbiosis industrialized recirculating aquaculture system, in which all the water produced by aquaculture enters the water-loving plant hydroculture device through a biological filter, then performs water quality allocation, and then returns to the aquaculture pond. Water purification by plants is inefficient and not suitable for high-density and large-scale production

[0010] Chinese Patent No. 201120090260 discloses a zero-emission aquaponics circulation device, which adopts a relatively common device structure and lacks implementation details

[0011] Although there are so many technologies, such equipment has not been widely used in our country

Investigating the reason, the inventors have found two main reasons after long-term research. First, there is a lack of implementation details, such as collection, sewage and other equipment. It needs to be supplemented, and the original intention of recycling is lost; secondly, it cannot effectively balance the different purification effects of microorganisms and plants on water bodies; thirdly, and more importantly, the production efficiency is not high, the input / output ratio is too high, and the industrialization promotion is lost. source of profit
