After user obtains a kind of closed pond circulation flowing water culture system as Figure 1-10 shows, first to cultivating pool It the bottom unit A1 and is transformed, makes to form angle α between the second section 7 and horizontal direction of the bottom cultivating pool unit A1 5-10 ° of the gradient, and the groove 8 for being 130-160cm in the first section 6 setting depth.Arc panel 11 is taken, adjacent arc panel 11 is made Between the knot that is matched by the first slot shoulder 1112 of interconnecting piece 111 and the first slotted eyes 1111 of another interconnecting piece 111 Structure realizes the two splicing, and threaded hole 1113 and another interconnecting piece on the first slot shoulder 1112 for passing through an interconnecting piece 111 The corresponding structure of threaded hole 1113 on 111 the first slot shoulder 1112, is achieved a fixed connection by screw.It is sequentially completed remaining The installation of arc panel 11 is finally spliced into complete main body 1.Bottom plate 3 is directly inserted in 1 inside of main body that arc panel 11 surrounds again Wall lower part makes bottom plate 3 be fixedly mounted on the lower part in main body 1, forms rock-steady structure.Above structure is placed in groove 8, in master Submersible sewage pump 4 is installed in vivo and is laid with sewage pipe 5, cover board 2 is clamped into 1 top of main body, that is, utilizes the card slot 23 and arc of cover board 2 The trip 112 of the inner sidewall upper portion of plate 11 is spliced, and the first joint tongue 1121 is made to protrude from the part and of the first tenon shoulder 1122 Two slotted eyes 231 match, and realize that cover board 2 is fixedly connected with 1 top of main body.Sewage pipe 5 runs through cover board from sewage pipe installing port 21 2, and stretch out the outer settling zone B1 to annular processes canal B of cultivating pool unit A1.

In the breeding process, the flowing of water body in annular processes canal B is driven by the extraction breeding wastewater of sewage pipe 5, And so that water is flowed through gravity flow culvert pipe 9 and flow back into cultivating pool unit A1, helicoid circulation is formed, the excrement of cultivation object is driven It is mobile with residual bait, it sinks to the gradient of the residual bait, excrement of bottom of pond under gravity and circulation effect along the second section of bottom of pond 7 and slides, The first section 6 is converged to, and is entered in main body 1 by the netted hole 22 on cover board 2.At the same time, bio-toilet modules A 11 Cover board 2 is isolated from module-external for object is cultivated, and guarantees cultivation object security.

Start submersible sewage pump 4, the excrement in bio-toilet module and residual bait will be collected in by the water outlet of submersible sewage pump 4 through blowdown Pipe 5 is discharged in the settling zone B1 of cultivating pool unit A1 to annular processes canal B.Tail water containing waste carries out in settling zone B1 After precipitation process, by be connected to water pipe B5 enter biological cleaning area B2, emergent aquactic plant section B21 in reed or wild rice stem in carry out The superfluous nutriment of nitrogen, phosphorus etc. in water is adsorbed, removes nutritive salt in water in the waterweed or hornwort in submerged plant section B22 And adsorbing heavy metal in water element such as arsenic, zinc, copper, cadmium, lead etc., in the Eichhornia crassipes in biological floating bed section of B23 or greatly poly- algae Except nitrogen, the phosphorus in water body.Tail water after biological cleaning flows into water reserve B3 by separation net B4 and is back to through gravity flow culvert pipe 9 Cultivating pool unit A1.It repeats the above steps, is repeatedly recycled.

In conclusion a kind of closed pond circulation flowing water culture system provided by the utility model, is based on " bio-toilet Module " and " annular processes canal " form cultivation tail water/waste water separation-purification-water storage-recycling systemic circulation cultivating system, energy Enough realize healthy aquaculture, environmental-friendly, resource-effective, increasing both production and income.So the utility model effectively overcomes in the prior art Various shortcoming and have high industrial utilization value.

The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
