Abstract

An ecotypic fish farming system belongs to the field of fishing facilities and particularly relates to the design of an intensive fish and shrimp aquaculture appliance. The ecotypic fish farming system mainly structurally comprises a pond 1, a sewage collecting opening 2, a drain pipe 3, a sewage collecting tank 4, a water pump 5, a circulating ditch 6, a sprinkler head 7 and an aerator 8. The technical scheme of an integral water self cleaning circulating route includes that fish farming sewage of the pond 1 flows to the drain pipe 3 via the sewage collecting opening 2 at the centre of the bottom of a fish pond to enter the sewage collecting tank 4 outside the pond, and is pumped into the circulating ditch 6 positioned on a pond bank by the water pump 5, eventually cleaner purified water returns to the original aquaculture pond after purification processes such as absorption of plants such as waterweeds and the like in the circulating ditch, conversion of attached microorganisms, sedimentation of excrement and residual bait granules and the like, thereby realizing circular self-cleaning circulation. The fish farming pond has the advantages of 1 water saving, 2 favor of rapid growth of fishes and shrimps and improvement of aquaculture density due to the fact that water is continuously renewed by the aid of self-purification, and 3 simple structure and suitability for modification and popularization of pond standardization.

Description

A kind of environmental fish farming system

Technical field

The utility model belongs to facility fishery field, is specifically related to the design of a kind of raising fish and shrimp facility that intensifies in the marine industry.

Background technology

Traditional fish and shrimp culture pond does not have supporting water treatment facility, and its breeding wastewater can not the repetitive cycling utilization, and water consumption is big, and the waste of water is serious, and the fishes and shrimps growth rate is slow, and cultured output is also not high.

Summary of the invention

The utility model carries out circular treatment with the breeding water body in traditional raising fish and shrimp pond, realizes the repetitive cycling utilization of aquaculture wastewater, to save the breeding water amount; And the continuous self-purification by cultivating system, the purpose that the raising that realizes breeding density and fishes and shrimps are grown fast.

To achieve these goals, the technical solution of the utility model is:

1, a kind of environmental fish farming system is made up of pond and supporting water circulation facility.The pond shape is generally square, also can be circle or rectangle, but square or circle more help the central authorities that dirt concentrates on the pond; The periphery of pond bottom is high slightly, central authorities are low, and similar " the bottom of a pan shape ", minimum point is provided with dirty mouthful of collection, and at this mouthful horizontal blow-off pipe is installed, so that the water in full pond can all flow out outside the pond from blow-off pipe; Blow-off pipe outside the pass-out pond links with the dirty pond of the collection that is positioned at pool side; Collecting dirty pond enters the circulation ditch that is positioned at the ridge, pond periphery by the water pump water lift and links with it, the circulation ditch excavates on Chi Geng, can center on a complete week of the ridge, pond, it also can be incomplete part, in general, the reservoir storage of ditch is big more, the ability of the purified treatment aquaculture wastewater of circulation ditch is just strong more, but trench normally can be subjected to the restriction to a certain degree of the ridge, pond road on Chi Geng, the degree of depth of the ditch of general excavation is 0.5m-1m, the width of ditch is 0.5m-2m, and concrete width can be decided according to the width of Chi Geng, but while Chi Geng is if leak covering film; Circulation ditch end is connecting fountain head or the water distributor that is positioned at the top, pond.

2, arrange aerator on the water surface of pond, waterwheel aerator preferably, its work causes that culturing pool flows to same direction rotation, also can be at the bottom of the pond covering film, be beneficial to the sewage draining exit position that the residual bait ight soil of fishes and shrimps etc. is easier to concentrate on the pond bottom center; The sewage draining exit position also is provided with screen cloth in case fishes and shrimps are escaped from; Blow-off pipe arises from sewage draining exit and level is imbedded at the bottom of the pond, and the other end is opened on the dirty pond of collection; Collect the sewage draining exit position that is lower than slightly at the bottom of the pond, dirty pond at the bottom of the pond, pond.

3, plants such as water purification plant such as plantation pasture and water vegetables such as green foxtail, reed, wild rice stem, water spinach in the circulation ditch.

4, carry the aquaculture wastewater of ight soil such as fishes and shrimps and residual bait in the pond under the drive of work such as waterwheel aerator, sinking and aggregation are in the sewage draining exit position of pond bottom center, and by with the pond of blow-off pipe UNICOM outside water pump in the dirty pond of collection pump in the circulation ditch water-soluble toxic waste such as NH in the aquaculture wastewater ₃Deng material, the absorption of the rhizome of the plants such as pasture and water in the circulation ditch is purified with the microbial transformation of adhering to, particulate matters such as ight soil in the sewage and residual bait slowly are deposited in bottom of trench in the circulation ditch, final clean relatively purifying waste water again in the former cultivating pool of getting back to of fountain head or water distributor, the effect of fountain head or water distributor is further to contact to water body oxygenation with air by the watering mode.

Technical scheme is summarized as follows: a kind of environmental fish farming system is collected dirty pond, water pump, circulation ditch, fountain head and aerator and is formed by dirty mouthful of pond and collection, blow-off pipe; The pond is a square, also can be rectangle or circle, and pond bottom is periphery high slightly, central low " the bottom of a pan shape ", and lowest part is provided with dirty mouthful of collection, and collects dirty pond in the horizontal blow-off pipe of this mouthful installation UNICOM to the pond; The position is lower than the pond bottom sewage draining exit slightly at the bottom of collecting pond, dirty pond, and water pump is positioned at the bottom of the collection pond, dirty pond; The circulation ditch excavates on Chi Geng, can center on a complete week of the ridge, pond, also can be incomplete part; Water purification plants such as circulation ditch plantation pasture and water, vegetables.The route of whole auto purification water circulation is: the aqiuculrue sewage-dirty pond-water pump of the dirty mouth-blow-off pipe collection of fishpond bottom-central authorities collection-circulation ditch-fountain head-pond, realize the circulation self-cleaning that goes round and begins again.

A kind of its advantage of environmental fish farming system is: the one, and water body recycling saved the breeding water amount; The 2nd, breeding water body is brought in constant renewal in, and water quality is good, and fishes and shrimps are fallen ill less, helps the raising of quick growth of fishes and shrimps and cultivation density; The 3rd, simple in structure, cost is low, operational administrative and easy to maintenance, be suitable for pond facilityization and applying that standardization is transformed.
