Nano bubble pond 6 using residence time length, charging property in micro-nano air-bubble, self is pressurized and dissolution, shrinkage,
The nine big features such as electrokinetic potential is high, generate free radicals high-efficient ion, oxygen transfer, breeding water body anoxic and physiological activity promote
It is applied to the present invention.In the environment of high density intensive progress aquaculture, fish is good in the control of height dissolved oxygen in water body
Health and growth are a vital rings, use ultra-fine microbubble technique to replace traditional oxygenation way, can greatly improve fish
Activity and yield, be the powerful guarantee of industrial circulating water aquiculture.In addition, micro-nano bubble also has stimulation fishing, shrimp
The effect of class growth and strengthen immunity.
Nano bubble pond of the invention has the advantage that
1) residence time is long in water.After general bubble generates in water, the water surface can be quickly risen to and rupture disappearance, i.e.,
It is short there are the time.And the rate of climb of micron bubble in water is very slow, is had tens seconds by generating to final rupture to disappear
Clock is even up to a few minutes, thus can in water the residence time it is longer.
2) charging property.Micron bubble surface is negatively charged, and relative to common blister, institute is negatively charged relatively high,
The surface loading of general 30um bubble below in -40mV or so, this be also micron bubble can largely flock together the time compared with
One of the reason of length is without rupturing.Using the negatively charged of micron bubble, substance positively charged in water can be adsorbed, to going to remove water
Good effect is played in the absorption and separation of middle suspended matter or pollutant.
3) self pressurization and dissolution.Pressure inside bubble is related with surface tension, and the diameter of bubble is smaller, internal pressure
It is bigger.Due to the diameter very little of micron bubble, specific surface area is very big, so its internal pressure is bigger than the pressure of environmental liquids
Very much, and just because of this internal pressurization of micron bubble and the advantage of large specific surface area, its gas dissolution capacity is milli
As many as the hundred times of meter level bubble.Because solubility and pressure have much relations, micron bubble internal pressure increases to one
When determining threshold, interface can be made to reach hypersaturated state, while the gas in more bubbles is dissolved into water, itself also can
Slowly dissolution disappears.
4) shrinkage.Micron bubble is pressurized after generating in water because of itself, the continuous contraction or expansion of meeting, and diameter is
Change always, the bubble of 20um~40um can arrive 8um or so with the speed search of 1.3um/s, and then contraction speed can soil
It sharply increases, is hereafter further split into nano grade air bubbles and completely dissolves in water.
5) electrokinetic potential is high.The surface of micron bubble can adsorb electrically charged ion such as OH-, and in this OH-ion layer
Around, and it can be distributed counter charges sheath such as H+, the surface of such micron bubble is formed electric double layer, the electricity at electric double layer interface
Position is also known as electrokinetic potential, and the height of electrokinetic potential largely determines the absorption property at micron bubble interface.
Because of the shrinkage of micron bubble, so that charge ion is largely gathered in the interface of bubble within the section time, until bubble is complete
Before full rupture dissolution, electrokinetic potential can all increase always, and it is better to the absorption property of charged particle in water to show.
6) ion is generated free radicals.General 10um micron bubble below is in the case where continuous shrink, the electricity of electric double layer
The density of lotus can increase rapidly, and when bubbles burst, the positive and negative charge for having reached high concentration sparks savings
Energy release, generates a large amount of radical ion, such as oxonium ion, hydrogen ion, hydroxyl ion.And hydroxyl radical free radical tool therein
There is very strong oxidation, the effect to purify water well can be played with some organic pollutants for being difficult to degrade of oxygenolysis
Fruit.
7) oxygen transfer is high-efficient.During Air Exposure waste water, the mass-transfer efficiency of oxygen is to influence waste water treatment efficiency
One of an important factor for, and the size of bubble diameter is inseparable with the mass-transfer efficiency of oxygen when aeration.Due to micron gas
Bubble has very big specific surface area, in water can stay longer, in addition the pressurization of itself, so that the mass transfer of gas-liquid interface
Efficiency can continue to enhance.
8) breeding water body anoxic.Oxygen is the basis of metabolism, and anoxic is the source of aquaculture disease.Due to air pressure, temperature
The factors such as the density of degree variation, the pollution of water body organism matter and aquaculture, change greatly regional, timeliness oxygen concentration,
Seriously affect fishing, shrimps survival condition.Due to pursuing high-density breeding, water temperature is high in water body, and residual bait and fish fecaluria are easy corruption
It loses and the carbon dioxide etc. of fishing class discharge causes water pollution issue serious.It, can nature procreation under normal aerobic ecological environment
A large amount of aerobic bacteria decomposes these organic contaminations.But hypoxgia, it is typically easy to by the ammonia nitrogen, nitrous acid, titanium dioxide of oxygen solution
The noxious materials such as sulphur largely occur, anaerobic bacteria mass propagation, in addition virus attack, often occurs dead.Utilize micro-nano bubble
It is small in size, and finally rupture in water, the characteristics of gas can be dissolved completely in water, using efficient aquatic products oxygenation, it can improve
Cultivation water.
9) physiological activity promotes.In modern aquaculture technology, the problem of simple anoxic, is easier to solve.Micro-nano gas
Steep not only oxygen-enriching, it is often more important that have and promote physiological active functions, micro-nano bubble is raw for the promotion of aquaculture
Reason activity has a positive effect, micro-nano bubble for fishing, shrimps acceleration blood circulation, for cell, blood flow warm effect, right
In direct a large amount of oxygen supplys of the gill and digestive organs, oxygen molecule can be directly entered blood etc..Micro-nano bubble is applied in aquaculture,
Blood flow accelerates 1~2 times, and growth is with the raising of nearly 2 times of speed of weight increment, and actively, culturing time can reduce nearly half to food.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
