Description
Technical field
The utility model relates to the aquaculture facility, especially the indoor high-density shrimp culture apparatus.
Background technology
Present many regional prawn culturings adopt the mode of desalination cultivations, and the raiser adopts the method that adds fresh water that the salinity of breeding water is progressively reduced, finally at fresh water or be tending towards culturing in the environment of fresh water.There is data to be illustrated in the water that every production 1kg prawn under traditional aquaculture model approximately needs 20000L, so the desalination cultivation of prawn has consumed a large amount of freshwater resources.Breeding wastewater causes the fisheries water environment to be polluted in breeding process simultaneously, and ecotope is destroyed.In addition, at fresh water or be tending towards culturing in the environment of fresh water the prawn quality of coming out and having good that breed is come out in the water environment of salinity.
Though circulating water culture system has solved the dependence of breeding production to environment effectively, reduced the pollution of breeding wastewater to environment.But also there is high energy consumption in circulating water culture system, can produces the often problem of maintenance of mud, needs; And single processing unit can only be handled certain or some pollutant; If want to reach purification fully, must several kinds of different processing units be incorporated in the circulation breeding wastewater.
Artificial swamp has caused people's extensive concern as a kind of wastewater processing technology in recent years; Its mechanism of action combines physics, chemistry and biological triple synergy, shows as filtration, absorption, deposition, ion exchange, plant absorbing and microbial metabolism number of ways.Research shows that this technology can not only effectively remove organic matter, nitrogen, phosphorus, heavy metal and pathogeny microorganism, and the investment operating cost is low, convenient for maintenance management.But at present, have only the research that artificial swamp is applied to handle freshwater low-density fish culture waste water, do not relate to artificial swamp is used to handle the waste water that the brackish water indoor high-density is supported shrimp.
The brackish water salinity is 5～15 ‰, when becoming a mandarin the sea by rivers fresh water and sea water mixing form, abundant brackish water resource is arranged in coastal river mouth.Therefore utilizing coastal river mouth brackish water to replace the freshwater aquiculture prawn, is a trend of the sustainable sound development of shrimp culture industry.
The utility model content
The purpose of the utility model is to provide the shrimp culture apparatus of a kind of water saving, energy-conservation, low-carbon (LC), efficient, environmental protection, and promptly brackish water combined artificial wetland indoor high-density is supported the device of shrimp.
The technical scheme of the utility model adopts shrimp-cultivation pool, artificial swamp and oxygen system; Oxygen system is made up of air pump, tracheae and gas head; It is indoor to it is characterized in that having a plurality of shrimp-cultivation pools to be connected in parallel on; Adopt pvc pipe to be connected between shrimp-cultivation pool and the artificial swamp, more than the height of water 1m between shrimp-cultivation pool and artificial swamp; The area ratio of shrimp-cultivation pool and artificial swamp is 0.8～2.0: 1; Each shrimp-cultivation pool hangs 2～3 nylon mesh sheets and 2～3 bait observation platforms, and placing density in the shrimp-cultivation pool is 1～1.5/m
2The gas head; Artificial swamp adopts a composite vertical current artificial wetland and a plurality of compound horizontal flow artificial wetland tandem compound; Shop corallite in the composite vertical current artificial wetland; Whole composite vertical current wetland is divided into downstream wetland and upstream wetland two parts, and the centre separates with partition wall; The compound horizontal flow artificial wetland that a plurality of head and the tail connect is spread respectively with microlith sublayer, big stone layer, road slag blanket from top to bottom successively; Plantation variety classes salt tolerant wetland plant in the artificial swamp; Each artificial swamp is only planted a kind of salt tolerant wetland plant; At collecting basin of the terminal connection of artificial swamp, collecting basin is provided with 2～3 gas heads; Collecting basin adapted immersible pump water lift is transported to each shrimp-cultivation pool.
The utility model has the advantages that brackish water resource capable of using solves the difficult problem of lot of consumption freshwater resources in the prawn culturing process; Utilize the utility model to produce 1Kg shrimp water in 400-600 rises scope, the water consumption of supporting shrimp 20000L with respect to traditional pond is obviously much lower; Can reach 5-6Kg/m
2Output, support shrimp 0.5-1Kg/m with respect to traditional pond
2Output obviously much higher, reach reduce the production run cost, reduce the waste water of shrimp breeding discharging, the protection water environment, cut off the shrimp disease that causes because of the water source generation, improve the quality of cultured prawn; Also have small investment, characteristics such as easy and simple to handle, easy to maintenance.
