Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to figure 1, a kind of water body purification efficient circulation cultivating system, supporting healthy aquaculture pond 1 by aquatic products master forms with the plant filter tank 2 being connected successively by water pipe, biofilter 3 and oxygenation pond 4, it is characterized in that: the water inlet in plant filter tank 2 is connected with the discharge outlet of culturing pool 1, the water inlet of biofilter 3 is connected with the discharge outlet in plant filter tank 2, the discharge outlet of oxygenation pond 4 is connected with the water inlet of culturing pool 1, forms modular cycle water pond breeding ecological device.This system combines relatively independent breeding, has effectively realized different interbiotic Mutualism relations, has broken through traditional single pond culture pattern.
Aquatic products master described in this example device supports healthy aquaculture pond 1 and is made up of 3 mouthfuls of ponds, arranged in series, the main foster cultivation of carrying out large freshwater fish and famous-particular-excellent freshwater fish; Plant filter tank 2 is made up of pretreatment pool 8, high-level reservoir 9 and wetland 10; Biofilter 3 is made up of sedimentation basin 11, biofilter 12 and clear water reserviors 13.
It is east-west that aquatic products master supports healthy aquaculture pond 1, is rectangle, and area is about 667 × 2m2, and depth of water 1.5-2.0m, at the bottom of shale.Between pond, mutually connect by culvert pipe, culvert pipe is positioned at bottom, the ridge, pond.Front end water inlet at culvert pipe is inserted a standpipe, and riser top is set up short sleeve in order to regulate and control water level; For preventing the fry string pool, add again one outward at standpipe and block cover pot.When operation, sleeve pipe is extracted out, so that the water that is rich in oxygen on top layer, previous stage pond flows into voluntarily the bottom in next stage pond under the effect of pressure differential, increased pond bottom dissolved oxygen level, form water body simultaneously and stir up and down the dissolved oxygen that is also beneficial to pond and be evenly distributed.
Aquatic products master supports healthy aquaculture pond 1 and is divided into cage culture district 5, collecting dung district 6 and purifying area 7 parts.Cage culture district accounts for 5% left and right of the pond gross area, exchanges by microkinetic pushing equipment net cage water body; Distribution collecting region, area is slightly larger than cage culture district, and timing is collected, timing extracting fish faeces, makes it in pond, not form accumulation; Purifying area, accounts for 95% of the pond gross area, purifies fish excreta and the residual bait etc. of failing to discharge outside pond.
Described plant filter tank 2 specifications are 8.0m (length) × 3.0m (wide) × 2.0m (height), are made up of pretreatment pool 8, high-level reservoir 9 and wetland 10; Wherein, Wetland Substrate is laid from bottom to top according to particle size, and order is thick slag, lime stone, rubble, coarse sand; Divide tri-grades of A, B, C by differing heights gradient, difference in height is 0.4m.Water inlet adopts self-made punching pvc pipe water distribution, and delivery port is positioned at the bottom in pond, connects PVC outlet pipe.The inlet and outlet pipe lines that high-level reservoir, plants filtering bed are connected with culturing pool, is all equipped with valve and tap, can regulate and control voluntarily Inlet and outlet water flow.
Described biofilter 3 is made up of sedimentation basin 11, biofilter 12 and clear water reserviors 13.Sedimentation basin is rectangle or is circular, brick, barnacle, and internal layer should be smeared five layers of watertight composition.For reaching dark precipitation, Chi Ding adds a cover.At the bottom of pond, should there is 1~3% the gradient, be convenient to clean with water blowdown.Sewage draining exit and feed water inlet are established in bottom, pond, and top should be provided with gap.Sedimentation basin generally can be divided into 2 to several lattice.Biofilter 12 is sand filter, and conventional filtrate is sand, gravel, oyster shell, quartz sand, medical stone, micropore ceramics, coral sand, diatomite etc.; The thinnest one deck sand material diameter is 0.15~0.20mm, and effective depth reaches 1m.Between the filtrate that has hole, protozoa and bacterium self-assembling formation biofilm, by means of the effect of microorganism, to reduce the content of ammonia nitrogen in water, nitrite, nitrate nitrogen.Clear water reserviors 10 are cement pit, for holding of water after carrying out a biological disposal upon.
Water side, biofilter bottom is provided with the PVC collector pipe of perforation, and end water body is collected and flowed into oxygenation pond 4 through bottom collector pipe.On each collector pipe of oxygenation pond 4 bottoms, insert a standpipe, riser top is a little less than substrate plane, and biofilter water outlet is flowed through after collector pipe and routed up by standpipe like this, increases and the contact area of air, is convenient to the water outlet reoxygenation lower to dissolved oxygen.The water outlet of oxygenation pond 4 enters cultivating pool 1 through outlet pipe drop.
The utility model is a kind of water body purification efficient circulation cultivating system, can effectively improve the water quality of cultivation water outlet; Between pond, between upper and lower water layer, miniflow water is evenly distributed dissolved oxygen, has increased the dissolved oxygen of water body; In breeding process, cultivate out water circulation use, effectively saving water resource, has realized the healthy aquaculture of fish.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow the personage who is familiar with this art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify; effect is similar, all should be encompassed in protection domain of the present utility model.
