Technical field
The utility model relates to the industrial circulating water stichopus japonicus facility of keeping a full stand of seedings.
Background technology
The important good aquatic products kind that apostichopus japonicus culture is cultured structural adjustment as the rising industry and the northern area of Chinese aquaculture, economic benefit is high, and development potentiality is big.Though China has obtained significant progress in apostichopus japonicus culture research, artificial breeding and artificial fecundation work are taken its place in the front ranks of the world, propagate artificially also flourish.2004 are only the bright sea cucumber output in Shandong Province reaches 5.7 ten thousand tons, and the holothruian cultures gross output value increases by 30% than the last year more than 7,000,000,000 yuan, accounts for 1/3 of the whole province's mariculture gross output value, becomes important holothruian cultures base, the whole nation.Yet; The technology of keeping a full stand of seedings the winter of the young seedling of stichopus japonicus in recent years; Still exist the problem that energy consumption is big, cost is high, become one of major limitation sexual factor of the sector development, the energy-saving and emission-reduction problem that therefore solves in the process of keeping a full stand of seedings current winter becomes a kind of urgent social demand and the market demand already.
The biological property of stichopus japonicus: stichopus japonicus is liked living in the shallow sea at the bottom of the cay, crawls in the seabed, and is slow in action, 10 minutes movable 1 meter.Like in the abundant place of marine alga.Ingest: with organic fragment, algae and protozoa etc. are brought into together with silt when taking the photograph.The peak of ingesting appears at 2-3 month, and minimum is August.Growth temperature: the optimum temperature of children's ginseng growth is the 19-20 degree, and comfort zone is the 15-23 degree, and the sea cucumber growth temperature of 5-15cm is the 10-15 degree.Breeding: sea cucumber begins to lay eggs when water temperature 15-17 spends, spawning period water temperature 17-20 degree.
Along with the raising of China's stichopus japonicus artificial breeding technique, propagate artificially and the propagation industry constantly develops, and culture and propagation is released and all needed a large amount of high-quality seedlings.In stichopus japonicus artificial breeding process, to mid-October to early November, the most of individual's body of its young ginseng is long have been reached about 1cm and the variable color ginseng; Promptly translucently become sepia, russet or light green by original, though at this moment seedling has reached the pond specification, the specification of seed has a lot also very little; Individual difference is also bigger; Culture and propagation is released with this seed, tend to, cause that to culture survival rate low excessively with the propagation rate of recapture because winter temperature is low less with specification.For further improving the survival rate that juvenile stichopus goes out pond specification and aquaculture, carry out keeping a full stand of seedings indoor wintering, can effectively improve the adaptive capacity of juvenile stichopus to environment, increase and culture weed survival rate.
Stichopus japonicus in the winter mode of keeping a full stand of seedings that northern China adopts now mainly is that culture in the workshop, plastic tunnel is cultured modes such as adding the insulation measure; Through taking means such as the heating of boiler seawater, underground sea water, residual heat of electric power plant, solar energy to improve indoor temperature and culture the water temperature of water in winter, reach the requirement of the cultivation water environment of seedling of Apostichopus japonicus.The boiler seawater heats and constantly changes water discharging link and wasted a large amount of energy consumptions, has caused the raising of aquaculture cost and the pollution of a large amount of breeding wastewaters.Owing to these reasons, the quantity of exchanged water that traditional stichopus japonicus is kept a full stand of seedings every day is merely 30~40% of total breeding water body, mainly is that energy consumption is big, because the cost of boiler heating is too high; And energy-conservation circulating water cultivation can at utmost be avoided the loss of heat, so can strengthen quantity of exchanged water, improves the freshness of water; Accelerate the growth rate of seedling, improved economic benefit greatly, guaranteeing under the situation that bait does not run off; The quantity of exchanged water of every day can reach more than 200%; And than traditional stichopus japonicus technology of keeping a full stand of seedings, water saving is more than 90%, and is energy-conservation more than 50%.Can show nowadays, also not have a kind of recycling technology that utilizes to realize technology and facility that stichopus japonicus survives the winter and keeps a full stand of seedings both at home and abroad.
The utility model content
The utility model is in providing a kind of energy-saving industrial circulating water sea cucumber facility of keeping a full stand of seedings, and the utility model has solved does not have a kind of recycling technology that utilizes to realize the stichopus japonicus problem of facility of keeping a full stand of seedings of surviving the winter at present.
For addressing the above problem; The utility model adopts following technical scheme: the energy-saving industrial circulating water stichopus japonicus facility of keeping a full stand of seedings, the stichopus japonicus that it is provided with by both sides in the workshop the hold concurrently biofilter, the second level, disinfection by ultraviolet light well (8), water quality of eddy current type separate tank (2), sieve bend separate tank (3), buffering regulating reservoir (4), dissolved air flotation pond (5), biofilter (6), degassing pond (7) that pond (1) and workshop one end be provided with of keeping a full stand of seedings adjusted pond (9), circulating water quality on-line measuring device (10), centre drain (11) and formed; In the workshop each stichopus japonicus keep a full stand of seedings water in the pond (1) through cycle water water return pipeline in the centre drain (11) from flowing to eddy current type separate tank (2), separate residual bait ight soil silt in the water outlet; Water outlet to sieve bend separate tank (3) is further isolated granule foreign; Again by the circulating pump water lift in buffering regulating reservoir (4) to dissolved air flotation pond (5), through pneumatically supported mode separating suspension and colloid albumen impurity; Flow into biological cleaning pond (6) and degassing pond (7) then, ammonia nitrogen, nitrite, hydrogen sulphide harmful substance are effectively removed through nitration reaction, and remove residual carbon dioxide and nitrogen pernicious gas; Pass through ultraviolet sterilization well (8) sterilization then and adjust pond (9) aeration aerating, be back to stichopus japonicus at last and keep a full stand of seedings in the pond with water quality; Form totally enclosed circulating water culture system; In addition, this circulation also is provided with circulating water quality on-line measuring device (10).
Energy-saving industrial circulating water stichopus japonicus keep a full stand of seedings facility and system and process, the characteristics that also have are: adopted a kind of unpowered eddy current type to concentrate separator that the large granular impurity in the aquaculture wastewater (silt, residual bait, ight soil) is carried out physical filtering in the circulation.
