Description
Technical field
The present invention relates to a kind of Degradation and Transformation nitrite method of microorganism, enzyme and inorganic salt somatomedin, can be used for sewage disposal, Aquatic product
Cultivation, the water harnessing engineering of flowing water system, belong to microorganism and enzyme thereof the technical field to waste water control.
Technical background
The sterling of nitrite is a kind of white or yellowish crystallization, has plenty of particulate powder, odorless, and taste is micro-salty and bitter, and easy deliquescence is soluble in water.
Can be used for the industry such as DYE PRODUCTION and some organic synthesis Treatment of Metal Surface, some construction sites winter constructs when also for doing cryoprotective agent.
Food color and preservative is also acted as in food production.In general, the content of nitrite that human body causes harm is: disposably take in 0.2
-0.5 gram can cause poisoning (toxic dose), disposable take in 3 grams can lethal (fatal dose), the poisoning therefore occurred is in the whole nation
Happen occasionally；Nitrite is relatively strong to the toxicity of fish, shrimp, is the key factor inducing eruptive epidemic disease in Cultivated water.When water nitrite is dense
After degree runs up to 0.1 mg/litre, by the Repiration of fish and shrimp, the gill filament entering blood, fish, shrimp erythrocyte number and amount of hemoglobin are gradually
Reducing, blood oxygen carrying capability is gradually lowered, and histanoxia occurs.Fish and shrimp nitrite poisoning is caused can directly or indirectly to cause multiple the farming disease harms,
There will be anorexia, travelling slowly, bradykinesia, rapid breathing, surface are raised the nose above water to breathe, body colour deepens, the gill filament is the symptoms such as dark red bag.Cultured prawn is normal
Dead at the bottom of pond, not having again manifest symptom after death, everybody is commonly called as " dead sick steathily ", is content of nitrite at the bottom of pond to this disease than more consistent view
Too high, when prawn is in shell at the bottom of pond, nitrous acid is poisoned and is died.In foster shrimp waters, the frequent indescribable fulminant of occurrence of large-area shrimp is dead, gives
Cultivation peasant household brings huge economic loss.
The itrogenous organic substances such as the feedstuff in breeding water body, first transfer ammoniacal nitrogen in water body to, then transfer nitrite nitrogen to, are finally nitrate nitrogen.Transformed
Cheng Zhong, the time needed from itrogenous organic substance to ammonia nitrogen is the longest, and the time from ammoniacal nitrogen to nitrite is shorter, but from the transformation time of nitrite
Longer.During whole nitrogen transformation, the time needed from itrogenous organic substance to ammonia nitrogen is the longest, multiple-microorganism serve as；From ammonia nitrogen to Asia
Nitrate is served as by nitrite bacteria, and the growth and breeding speed of nitrococcus is 18 minutes generations, and therefore it converts quickly；From nitrous acid
Salt is to be served as by nitrobacteria to nitrate, and the speed of growth of nitrifier is relatively slow, and its reproduction speed is 18 hours generations, therefore by
Nitrite transformation is the longest a lot of to the time of nitrate.It is known that when the concentration of ammonia nitrogen peaks (3～4 days), nitrite nitrogen is just
Beginning to ramp up, when the concentration of nitrite nitrogen peaks (3～4 days), nitrate nitrogen begins to rise.The effectively decomposition needs 12 of nitrite nitrogen
It the most longer time.Due to substantial amounts of bait throwing in breeding water body, cause a large amount of accumulation of nitrogen.Nitrogen by the effect of various microorganisms,
Being converted into ammonia nitrogen, nitrite and nitrate, on the one hand these three nitrogen is absorbed by algae and water plant, and on the other hand nitrate is at condition maturity
When by denitrification, nitrate nitrogen is converted into nitrogen.If water body reaches certain self-cleaning poised state, do not have external interference (as
Not by disinfectant), then the nitrogen cycle meeting ratio compared with normal of water, tri-state nitrogen can maintain stable state always.But in breeding water body, by
In regularly using disinfectant, harmful and useful antibacterial is killed all, oxygen under-supply, often result in nitrifying process and be obstructed, this
Being exactly ammonia nitrogen and the high main cause of nitrous acid content in water, owing to the conversion rate of ammonia nitrogen is very fast, therefore the problem of nitrous acid is the most prominent.Certainly,
Temperature also has considerable influence to water body Nitrification, and nitrobacteria is when temperature is relatively low, and Nitrification weakens, and causes nitrite accumulation.
Secondly, nitrite can also react the nitrous acid amine substance generating carcinogenic class with secondary amine class, is conducive to inferior ammonium nitrate to be formed time at the bottom of pH.
The most general employing is single or complex microorganism strain controls water quality, but owing to microorganism used therefor is affected by the external environment relatively big, anti-bad
Environmental impact is poor, sustains damage once system and is just difficult to recover.Main measure has following several way: 1. use the way of ozone.Due to
The price problem of equipment and installation question, popularization has certain difficulty, but is can be suitably used at nursery pond.2. add purebred nitrobacteria.
Being limited to obtain purebred nitrobacteria more difficult, cost is the highest, can only be confined in aquarium and fish jar use.3. use activated carbon.Every mu uses alive
Property carbon dust 2～4 kilograms, full pool spilling head, there is certain effect, cost is the highest.4. the consumption strengthening Vc in feedstuff also has certain effect.
5. other ways.It is relatively costly that these ways have, and some effects are of long duration.Therefore, event of being poisoned to death often has generation, it has also become the difficulties such as cultivation
One of disaster with reply.
