Background technology
With the development of society, the improvement of people's living standards, the nutritive value of the flesh of fish is increasingly approved by people, because
This, the demand of cultured fishes is growing day by day, still, and the problem of cultured fishes are maximum is asking of controlling of oxygen content in water body
Topic, water oxygen is not enough, can cause various problems, therefore, and solving the control of oxygen in water turns into the maximum problem of aquaculture.
Increasingly increase with people to marine product demand, in the case where marine fishing amount can not meet the market demand,
Mariculture industry has obtained swift and violent development but ecological mistake caused by extensive management, Resource Dependence type aquaculture mode
Weighing apparatus, environmental degradation, resource atrophy situation extremely serious closed circulations industrial aquaculture mode have water saving, take up an area less, support
The advantages of growing efficiency high and lighter environmental pollution, therefore rapid development cultural techniques have been obtained mainly using recirculated water
Cultivation, cultivating wastewater purification Posterior circle is used, water resource is both cost savings, wastewater discharge factories can be reduced again
Change in aquaculture system that primary producer's such as its species such as phytoplankton, algae is simple, quantity is few, be unable to full feeding density
The growth of high aquaculture organism needs, therefore to add a large amount of bait manually prepared to meet needed for the growth of aquaculture organism
The abundance of food manually added is nutritious, can greatly improve the growth rate of aquaculture organism but be delivered under the cultivating condition
Bait, all can not be effectively utilized by cultivation object, remainder is discharged into environment residual baits and row in the form of pollutant
Letting out the pollutant in thing, to be mainly nutriment contained therein and organic matter not high and dissolved oxygen is sufficient in organic concentration
In the case of, to the growth effects of fish less, be not cultivate the removal target of water process mainly, cultivation water process the most concern is
Nutritive salt and toxicant, the especially wherein removal of ammonia nitrogen.
Dissolved oxygen, during oxygen is the molecular gap that gaseous state has water, the amount that water dissolves in gas at a certain temperature be it is certain,
Temperature is higher, and the gas dissolved in is fewer, and salinity more high-solubility oxygen is also fewer.Just as one barrel of sand can pour water into,
It is impossible to add again equally after water is full of sand space, so, the gap of hydrone is full of rear oxygen by other gas
It can not dissolve in, the quick-fried pool is exactly that the pernicious gas in water is excessive, the gap of hydrone is by pernicious gas full of caused by not adding oxygen
's.
First, in breeding water body dissolved oxygen source：
1. photosynthesis：When daytime is sunny, planktonic algae and the strong photosynthesis of water plant produce big in water
The oxygen of amount, this is the main source of breeding water body dissolved oxygen.In the higher fine day of water temperature, dissolved oxygen even up to 20mg/L with
On, form hypersaturated state.
2. people acts on for mechanical enhancement：The high new water of the mechanical enhancement effect of aerator, filling dissolved oxygen, oxygenation agent of splashing are
Another main source of breeding water body dissolved oxygen.
2nd, in air oxygen dissolution：When breeding water body dissolved oxygen is unsaturated, particularly at night and early morning superficial water
When dissolved oxygen content is relatively low, oxygen diffusion is dissolved in water in air, can increase the dissolved oxygen level in superficial water.
3rd, the reason for breeding water body dissolved oxygen is not enough
1. cultivation density is excessive, the respiration of the aquatile such as fishes and shrimps is increased, and BOD also increases, easily caused
Water body dissolved oxygen is not enough.
2. when breeding water body overfertilization, planktonic algae is enriched very much in water.Night, the respiration of planktonic algae is extremely prosperous
Contain, oxygen demand is very high, easily cause water body dissolved oxygen not enough.
3. pond organic matter increases, bacterium amount reproduction will be caused, and bacterium amount reproduction also will largely consume pond water
Dissolved oxygen in body, so as to cause pond waters dissolved oxygen to decline, causes fishes and shrimps anoxic.
4. the rise of the solubility with temperature of water oxygen and reduce, while aquatic livestock and other biologies under the condition of high temperature
Metaboilic level is improved, and oxygen demand also increases, and easily causes water body dissolved oxygen not enough.
5. the reducing substances in water, when for example hydrogen sulfide, ammonia, nitrite etc. are more, its oxidation can also be consumed largely
Oxygen.
4th, the requirement of breeding water body dissolved oxygen and performance during fishes and shrimps anoxic
Dissolved oxygen in breeding water body should typically keep 5~8mg/L, should at least be maintained at more than 4mg/L.
During slight hypoxia, fishes and shrimps performance is had the fidgets, accelerated breathing, and it is movable in superficial water to have focused largely on, indivedual to raise the nose above water to breathe.
During severe hypoxia, a large amount of fishes and shrimps can raise the nose above water to breathe, and dehisce largely to gulp down air, swim powerless, or even death by suffocation.Oxygen mistake
The general non-hazardous of saturation, but cause gas diseases sometimes.
5th, influence of the dissolved oxygen to other noxious materials
Enough dissolved oxygens are maintained in water, can suppress to generate the chemical reaction of noxious material, reduction noxious material is (such as
Ammonia, nitrite and hydrogen sulfide etc.) content.Under conditions of with the presence of sufficient dissolved oxygen, generation pair after Organic substance in water rots
Fishes and shrimps harmful ammonia and hydrogen sulfide, through microorganism aerobic decomposition, ammonia can be converted into nitrite, be then converted into nitrate,
Hydrogen sulfide then changes into sulfate.Nitrate and sulfate are nonhazardous to fishes and shrimps.On the contrary, when dissolved oxygen in water is not enough, ammonia
It is difficult to decomposition and inversion with hydrogen sulfide, therefore these noxious materials easily accumulate the degree for reaching harm fishes and shrimps health.
Therefore, how not increase nitrogen content while water oxygen content is kept turns into a great problem of aquaculture.
