Description

Fish, vegetable and shellfish symbiotic type engineering circulating water double-layer culture tank

Technical Field

The utility model relates to a breed the groove, concretely relates to fish, vegetable and shellfish intergrowth type engineering circulating water double-deck breed groove belongs to aquaculture equipment technical field.

Background

At present, the development of fishery in China faces a serious challenge, and the problems of water body pollution, excessive pollutant discharge and the like commonly exist in pond culture. In order to increase the fishery ecological environment protection and reduce the tail water discharge of pond culture, in recent years, a pond engineering circulating water culture technical mode is gradually tested, demonstrated and popularized in a large scale.

The pond engineering circulating water aquaculture technical mode is a novel aquaculture mode, and the principle is that the pond is divided into a small water body water pushing aquaculture area and a large water body ecological purification area, the small water body water pushing aquaculture area is provided with a rectangular aquaculture water tank, cultured varieties are concentrated in the water tank for aquaculture, the water tank is provided with an aeration water pushing device, the water tank is provided with a water outlet end, and the water outlet end is provided with a sewage collecting facility for intensive aquaculture through continuous running water. The large water body ecological purification area carries out water body purification by stocking filter feeding fishes and the like. The core function of the mode is to intensively collect excrement and feed residues generated in the culture process through the launder, so that the pollution load of the culture water body is reduced to the maximum extent.

However, in actual production, because the water of the different degree of depth in the basin difference on the velocity of flow, the upper water velocity of flow is higher, and the pollutant can't effectively sink to the terminal dirty facility of collection of basin, and lower floor's water is because the velocity of flow is slow excessively, and the pollutant is more in the district's deposit of breeding, and the terminal collection rate of collecting dirty district of basin is lower, has great difference with system design collection rate.

Disclosure of Invention

An object of the utility model is to provide a fish, vegetable and shellfish intergrowth type engineering circulating water double-deck breed groove to solve the lower problem of current breed groove pollutant collection rate, thereby improve water purification efficiency.

The utility model discloses a double-deck breed groove of fish, vegetable and shellfish intergrowth type engineering circulating water is realized through following technical scheme:

the utility model provides a double-deck breed groove of fish, vegetable and shellfish symbiotic type engineering circulating water, includes the cell body, and the cell body top surface is uncovered and is located the surface of water top, and inside sets up end fish blocking fence and divide into two parts of upper and lower dark with the cell body, and the cell body goes out water end top and sets up the floating bed, sets up the same plant-planting hole of a plurality of diameters on the floating bed.

Baffles with the same height are respectively arranged at the lower parts of the water inlet end and the water outlet end of the bottom fish blocking fence, the upper parts of the baffles are connected with the end fish blocking fences, and the aperture of each of the bottom fish blocking fence and the end fish blocking fences is smaller than the minimum height of the cultivated fish.

The side wall of the top of the water outlet end of the tank body is provided with 4 fixing rings, the floating bed is separated from the tank body, the width of the floating bed is less than or equal to that of the inner wall of the tank body and floats above the water surface, and the planting holes at four corners are connected with the fixing rings through ropes.

The proportion of the top area of the floating bed covering the tank body is 30% -50%.

One or any combination of aquatic plants such as water spinach, cress and lettuce is planted on the floating bed.

And a nylon bolting silk net covers the periphery below the floating bed.

One or a combination of filter-feeding mussels and snails is put at the bottom of the tank body.

The working principle of the invention is as follows:

the utility model discloses breed the inslot, arrange different nutrition levels, breed ecological complementary animals and plants in position, realize quality of water regulation and control and nutrient substance cyclic utilization, reduce pollutant emission when improving the benefit of breeding. By planting the aquatic plants on the floating bed, the characteristics that the plant roots are developed and a large amount of nitrogen and phosphorus nutritive salt is required for growth are utilized to absorb the nutritive salt such as nitrogen and phosphorus generated by the fish excrement residual feed for biological in-situ regulation and control, and the eutrophication of the water body of the pond is relieved. The secretion produced by the plant root system can effectively promote the sedimentation of suspended particles in the culture water body and improve the feces collection rate of the culture water tank. In addition, the plants release oxygen from the root system to the water body through photosynthesis, so that the dissolved oxygen in the water body is increased. In high temperature summer, the floating bed can also be used for shading the sun and avoiding summer heat for the fishes. At the bottom of the culture tank, the sediment deposited at the bottom of the culture tank is converted into shellfish biomass through the filter feeding and purifying effects of the shellfish, so that the pressure of culture on a water body is reduced, the economic benefit is improved, the three-dimensional utilization of culture space resources is achieved, and the utilization efficiency of the culture space is improved.

The utility model discloses a breed groove compares with current commonly used breed groove, has the advantage of following several aspects:

firstly, the flocculation of aquatic plant root exudates promotes the precipitation of suspended particles and improves the collection rate of pollutants;

secondly, the absorption and utilization of nitrogen and phosphorus are increased and the concentration of nutritive salt in the water body is reduced through the absorption of plant root systems and the filter-feeding effect of shellfish at the bottom layer;

thirdly, the yield of aquatic plants and shellfish is increased while the fishes are cultured, and the economic benefit of the culture tank is improved;

fourthly, the floating bed plants have aesthetic value of landscape.

Along with the positive propulsion of the strategy of upgrading and increasing the efficiency of the aquaculture industry and energy conservation and emission reduction of the fishery in China, the utility model discloses a breeding tank can effectively advance the popularization of pond engineering recirculating aquaculture mode, and is significant to guaranteeing that the tail water of breeding is up to standard to discharge.
