Filter is processed, and the water containing impurity of outflow after mechanical filter and Separation of Proteins is carried out returns to culturing pool and recycles.
4th, ultraviolet (UV) sterilization
Ultraviolet radiation for sterilizing and disinfecting is the ultraviolet using appropriate wavelength, DNA (the deoxidation cores destroyed in microflora organisms cell
Ribosomal ribonucleic acid) or RNA (ribonucleic acid) molecular structure, cause growth cell death and (or) regenerative cell dead, reach
The effect of sterilizing.Ultraviolet Disinfection is purple using the high efficiency of particular design, high intensity and long-life UVC wave bands
Outer illumination water jets, various antibacterials, virus, parasite, algae and other pathogens in water are directly killed.
5th, ozonization
During ozonization is the ozone injection water produced by ozone machine, using the high oxidative property of ozone, water body is entered
Row sterilization.To raising biological almost non-hazardous, main the elimination of micro-organisms and harmful bacteria.
Ozone is a kind of strong oxidizer, and sterilization process belongs to biochemical oxidation reaction.
Sterilizing has following 3 kinds of forms：
1) enzyme needed for ozone energy oxidation Decomposition antibacterial endogenous glucose, makes bacteria inactivation dead；
2) directly with antibacterial, virus function, destroy their organelle and DNA, RNA, be subject to the metabolism of antibacterial
Destruction, causes bacterial death；
3) cell membrane tissue is passed through, invades intracellular, acted on the lipoprotein of adventitia and the lipopolysaccharide of inside, send out antibacterial
Give birth to penetrating sex distortion and dissolve death.

Oxygen-enriching to refer to and inject air using oxygen increasing pump in water, by the device bubble disintegration such as Bubbled stone, makes oxygen
It is soluble in water.Or utilize liquid oxygen apparatus, fluid,matching oxygen tray to make liquid oxygen efficiently be dissolved in breeding water body, improve breeding water body molten
Oxygen, meets the oxygen supply of Lobster existence.
7th, biofiltration
The waste circulation that aquatic organism is produced in water is as follows：
The first step, the Excreta of aquatic species and the food do not eaten will be changed into ammonia；That is because in these things
In need the antibacterial of oxygen that protein can be made to divide, and ammonia is poisonous (be commonly called as water mixed, smelly).
Second step, survives in the nitrobacteria in oxygen, ammonia can be changed into nitrite (NO2-)；Though nitrite
So only have less toxicity, but still have fatal murder by poisoning to aquatic organism.
3rd step, nitrite and rear is changed into nitrate (NO3-) by second nitrobacteria again；And this nitrate is several
Be it is nontoxic, but suddenly or to be chronically exposed in the nitrate of high concentration be harmful.But fortunately, the concentration of nitrate is
By changing water or water plant can be raised to reduce.
The antibacterial (Anaerobic Bacteria) that 4th step, nitrate etc. can not be depended on oxygen and survived is changed into nitrogen and distils,
Here it is one complete " nitrogen compound circulation ".
Nitrobacteria (Nitrifying bacteria) is a kind of aerobic bacteria, including Nitrosomas and Nitromonas.It is raw
Live in the water of aerobic or in layer of sand, play critically important role during nitrogen cycle purification of water quality.
Nitrobacteria is classified：Nitrous acid Pseudomonas and nitric acid Pseudomonas
The vital movement of nitrobacteria：
Nitrite bacteria (also known as ammonia oxidation bacteria), by ammoxidation into nitrous acid.Reaction equation：
2NH3+3O2→2HNO2+2H2O+158kcal(660kJ)。
Nitrate bacteria (also known as nitrite-oxidizing bacterium), by nitrite-oxidizing into nitric acid.Reaction equation：
HNO2+1/2O2=HNO3 ,-G=18kcal.
This two classes bacterium can obtain from above oxidizing process respectively and grow required energy, but its capacity usage ratio is not
Height, therefore growth is relatively slow, its averagely for when (time required for a bacterial reproduction generation) more than 10 hours.Nitrobacteria exists
There is in nature Nitrogen Cycling important function.This two classes bacterium is generally living together, it is to avoid product of the nitrite in water
It is tired, be conducive to body normal growth.Ammonia or ammonium salt in water just must can be changed under the collective effect of two class antibacterials more than
Nitrate, so that increase the available nitrogen nutrition of water plant.
The viable conditions of nitrobacteria：The survival of nitrobacteria needs moisture, in addition it is also necessary to very high oxygen, so can only give birth to
Live in the various filter materials for having micropore such as biochemical cotton, biochemistry ball, glass ring, ceramic ring.Moisture and oxygen is met only simultaneously
Supply, they could survive.Nitrobacteria optimum is lived in weakly alkaline water, grows when temperature reaches 25 degree or so
Breeding is most fast.
New water --->Enter aquatic organism --->Aquatic organism drains --->Excreta is decomposed --->Become ammonification --->Ammonia piles up water quality
Become mixed --->Nitrosomas procreation starts --->The first one-step forming of Nitrosomas bacterium colony --->Water quality becomes clear nitrite and starts heap
Product --->Nitromonas starts procreation --->The molding of Nitromonas group --->Nitrite is decomposed into nitrate --->Finish.Ammonia
Accumulation need 2-3 days, Nitrosomas tentatively sets up group probably needs 5-7 days, and the general 2-3 of group of Nitromonas is all, counts
Nitrifier is not normally cultivated by external force need one month.In this moon, temperature, oxygen, place three elements cannot stop.
8th, denitrification
The antibacterial (Anaerobic Bacteria) that nitrate etc. can not be depended on oxygen and be survived is changed into nitrogen and distils, here it is instead
Nitrifying process.
9th, carbon dioxide is removed
As biology can produce in metabolic process carbon dioxide newly being produced, carbon dioxide is long-term soluble in water to make water
Middle pH value rises, and water body is in acidity, unfavorable for the growth of Lobster, so needing, using aeration or ejecting device, to increase oxygen
Gas and water body contact surface device, reduce amount of carbon dioxide soluble in water, keep water pH value stable.
10th, source water treatment
As this kind of technology breeding spaces are closed, the water source for adopting is preferred with subsoil water or civil running water, if adopted
It is allowed for access after needing to carry out filter-sterilized again with extraneous river, lake water etc. breeding water body.
11st, lower water temperature
Breeding water body water temperature needs are constant, and maintain optimum temperature needed for Procambarus clarkii growth.If ambient temperature is difficult
To reach standard, it is necessary to increase water temperature regulater, the electromagnetic valve of heat exchanger is controlled by temperature sensor, water temperature regulater
Break-make and opening amount, realize that the water temperature of culturing pool is constant.
12nd, monitoring water quality
Detecting system can be with monitor in real time variation of water, if water quality index occurs serious change, monitoring system meeting
Alarm is sent, poultry feeders are processed in time.
13rd, cultivation concealed thing design
As Procambarus clarkii is that bottom breath is biological, Burden-Swimming Ability of KM is not good, and most times are perched in cell body bottom, are passed through
Increase stereoscopic multi-layer shrimp nest, or the bulk float of water float in culturing pool, make Procambarus clarkii have the place that growth is perched,
Avoid it is similar between cannibalisation, while also significantly increasing water body utilization rate and yield so that high-yield and high-efficiency benefit is cultivated into
