Description
Technical field
The utility model relates to aquatic products purifying aquaculture field, particularly relates to a kind of new and effective circulation aquatic products purifying aquaculture system.
Background technology
At present, ecologic breeding is owing to having economy, effective, availability high, and favor with being subject to people since ancient times, forefathers have invented the aquatic ecological culturing patterns such as four large Chinese carps are raised together with, mulberry fish pond, rice field fish culture, all achieve success hugely.Flourish in recent years along with aquaculture cause, the continuous progress of aquatic science and technology, the intensive culture pattern of high investment, high production makes aquaculture develop into a new stage, but incident be excessive risk, high pollution, make intensive culture enter into blind alley gradually; The Eco-breeding pattern of environmental protection causes concern, has various modes at present, and as multi items Polyculture, multi-element ecology circular biological aquaculture model etc., this several modes subject matter is, has plenty of not allow manageable, such as commonly raises together with; Some complex operations, cost intensive, sixty-four dollar question is, the economic benefit of this several Eco-breeding pattern is difficult to ensure.
So both environmental protection, health, can stablize again the intensive Eco-breeding pattern of high yield, be only the pattern of sustainable development, is the developing direction of current aquaculture.The cultivation of the modularization ecosystem can realize this target, and intensive culture pattern is constant, and economic benefit can ensure; The ecological functions module of regulation and control pond environment, different according to cultivation situation, can arbitrarily increase and decrease; Inclusion inside each module, according to the difference of cultivation situation, also can arbitrarily regulate, completely controlled, the adjustable ecology of one, whole intensive culture process can be guaranteed, keep the ecological balance of pond environment at any time, ensure carrying out smoothly of cultivation, and do not need to use medicine, environmentally friendly.
Meanwhile, culture fishery encounters two hang-ups, and one is the problem of environmental pollution that water resource and aquaculture produce, and another is the problem of aquatic products disease.This two problems is closely connected again together, and the pollution of water environment can cause growing of harmful bacteria, causes the frequent generation of disease.Tradition cultural technique also brings potential crisis while significantly improve area output; be mainly manifested in the victim that environmental pollution is not only in cultivation; also be one of pollution source of environmental pollution simultaneously; the nutritive elements such as the cultivation of fish shrimp crab shellfish comprises residual bait, chemical fertilizer, disinfection drug etc. to the pollutant in waters, the nitrogen phosphorus of particularly residual bait dissolving become the arch-criminal of Cultivated water eutrophication.The water quality of eutrophication is the precondition that cause of disease is grown, even may bring out red tide, brings the catastrophic effect of cultivation.
Prawn culturing is the active role in World Aquaculture all the time, but traditional prawn culturing mode of China runs into no small difficulty in recent years, the restriction of water resource on the one hand, often produce the water (Timmons and Losordo, 1994) that 1 kilogram of prawn approximately needs consumption 20000 liters.Be subject to great prawn disease puzzlement on the other hand, prawn culturing " pestilence " (viral disease) that the 1980's Mos are worldwide brutal, spread to southern large area by north in China from 1993, caused the economic loss counted in 10,000,000,000.
System mainly based on bacterium in traditional circulating water cultivation is utilize bacterium to remove superfluous nutriment in the treatment system of water circulation.Investment needed for such system and operating cost all higher at interior cost, cause this type systematic in applying, be subject to very large restriction (Libey and Timmons, 1996).
Therefore, a kind of system being used for aquatic kind, particularly prawn is needed.This system can realize recycling of water resource, reduces the consumption of water resource, can also suppress the generation of shrimp disease.Can reduce simultaneously invest and operating cost at interior cost, the benefit of increase system cloud gray model.

Over nearly 20 years, intensive aquaculture industry at home and abroad develops rapidly.World Water output reached 1.2 hundred million tons in 1996, and wherein 25% for propagating artificially.With this understanding, nitrogen contained by the feed thrown in breeding process, phosphorus approximately only have 9.1% and 17.4% to be assimilated by fish, the pollutant that its remaining feed and fish excreta are formed causes severe contamination to water body, sediments etc., causes the degeneration of shallow lake, causes marine site, local that red tide occurs; All kinds of chemicals used in aquaculture and antibiotic residue also pollute water environment, some biological habitats are destroyed, disturbs procreation and the existence of wild stocks, bio-diversity is reduced; The development of the finiteness restriction aquaculture of simultaneously water pollution and water resource, therefore, the process of aquiculture waste water and recycling receives publicity gradually, and the purified treatment of research breeding water body is the key technology of inland fishery sustainable development with recycling.
Current process breeding wastewater mainly comprises physico chemistry treatment technology and biologic treating technique, and typical method flow process has: the fishpond draining → pond → oxidation pond → sedimentation basin that catchments → heat oxygenation pond → fishpond reuse; Streaming rubble filter tank, fishpond draining → up-flow rubble filter tank → fall → heat pond → reuse, etc.Above method all adopts fishpond draining, the method in fishpond is discharged back again after purification, this just needs the biofilter setting up certain area, cost of investment will certainly be increased, and floor space is large, as Chinese invention patent number: 201120221800, patent name is: breeding waste water purifying device, adopt too and breeding wastewater is introduced in purifier, drain into again in fish pond after process.
In addition, in recirculating aquaculture system, most employing biomembrane nitrification tank purifies water, namely breeding wastewater is the relatively low nitrate of toxicity by biomembrane nitrification tank organic matter wherein and mineralized nitrogen, reach the object improving water quality to a certain extent, but this water treatment method of Long-Time Service can cause nitrate in breeding water body to accumulate in a large number, also cannot remove other nutritive salt such as organic particulate matter in breeding water body and Phos simultaneously.
(Authorization Notice No. is CN1653893A to the compound bio denitrogenation method of a kind of closed cycling aquaculture water of Chinese patent, publication date is on August 17th, 2005), disclose a kind of large-scale norm breakdown of water plants that utilizes and transform organic matter in breeding water body and ammonia nitrogen, the method effectively can remove the nitrate of a large amount of accumulation in breeding water body, but it is not obvious to the removal effect of other nutritive salt such as the organic particulate matter in breeding water body and inorganic nitrogen phosphorus, and this kind of water plants is applicable in fish closed recirculating culture system, and be not suitable in fresh-water fishes closed recirculating culture system.
Existing aquatic products purifying aquaculture system mostly relates to numerous and diverse physics, chemistry or biological cleaning process, but in actual process, the chemical reagent thereupon brought pollutes, physical cleaning efficiency is low, weak effect, and the side effects such as the eutrophication brought of carrying out a biological disposal upon, have a strong impact on the normal existence of aquatic biological, shorten the aquatic biological life-span, simultaneously because environmental pollution impact property defines secondary pollution again comparatively greatly.
