20mg/L；The BOD is BOD5.
It further include standing a period of time after dilution；Time of repose is 10~48h.
Invention has following advantageous effects:
1. fish pond uses lime disinfection, there are following ionic reaction Ca2++2H2PO4-----Ca(H2PO4-) 2 ↓ (slightly soluble belongs to
In citric acid soluble phosphorus) and Ca2++2HPO42-----Ca(HPO4-) ↓ (is insoluble, belongs to citric acid soluble phosphorus), to reduce the water in water body
The content of dissolubility phosphorus, and algae absorbs the ion phosphorus that phosphorus is the water-soluble state of absorption, therefore can make the supplement that cannot get phosphorus in water body,
Aquatic plants growth is slow, and photosynthesis is reduced, and the dissolved oxygen in turn resulted in water body reduces, and detests so that aquatic products occur and having
It eats, move about slow, slow in reacting, frequent the phenomenon that above water surface breathes.And in the case where dissolved oxygen is reduced, the anti-nitre of anaerobic species
Changing bacterium can be relatively more active, by the nitrate (NO in water body3 −) in nitrogen (N) pass through series of intermediate products (NO2 −、NO、N2O)
It is reduced to nitrogen (N2), the reduction of nitrogen content in system is also resulted in, and then influence plant growth and photosynthesis, and then make
Dissolved oxygen in water body is further reduced.
Water-soluble phosphorus is added in the application, to supplement the content of water-soluble phosphorus in water body, and then promotes the algae reproduction in water body, from
And the dissolved oxygen in water body is improved, and then avoid nitrate (NO3 −) in nitrogen (N) loss, save production cost.
2. destroying the microorganism balanced in water body, due to nitrite bacteria after lime disinfection sterilizing
Reproduction speed is very fast, is lower than 30min, and the breeding of nitrobacteria needs to cause nitrite bacteria and nitrification in water body more than 10h
The imbalance of bacterium, and the itrogenous organic substance in breeding water body, first switch to ammoniacal nitrogen, then switch to nitrite nitrogen, most in water body
It is afterwards nitrate nitrogen, it is more in the less water body of nitrobacteria in nitrite bacteria, the NO in water body can be made2 −Enrichment, cannot get
Conversion generates murder by poisoning to aquatic products, so that the aquatic products gill filament is in kermesinus, or even has rotten cheek symptom to occur.Nitrification is added in the application
Bacterium reduces NO2 −Enrichment makes aquatic products restoration ecosystem as early as possible, improves aquatic products yield.
It, will nitrification when water being added when using extrusion granulation and production 3. the application is defined the production technology of product
Bacterium is individually packed, in order to guarantee the survival rate of nitrobacteria, wherein extrusion granulation does not need to be added water as bonding
Agent, and be commonly granulated, needing to be added water makees adhesive, the reason is that, the nitrobacteria of addition is dormant state, once meet water
It can then be activated, that is, will cause loss, loss has two o'clock: 1) dissolution of inorganic salts causes salinity in environment excessive, in turn results in
Cell dehydration in nitrobacteria body, in turn results in death, can not play nitrification；2) nitrobacteria is activated, and consumes nutrients
Matter, so that and then leading to the death of nitrobacteria, nitrification can not be played in use, nutriment lacks.
4. the application is defined application method, inorganic nutrient substance is diluted to lower than 5%, mainly by this Shen
What bacterium that please be selected determined, bacterium selected by the application is low Facultative Halophiles, and inorganic salt concentration is more than 5% and easily causes nitrobacteria body
Interior cell dehydration causes the death of nitrobacteria, is unable to reach the purpose of breeding, and BOD is lower than 20mg/L, in order to
Nitrobacteria is set to form population advantage.Nitrobacteria belongs to autotroph, and organic concentration is not its growth limiting factor,
High organic content can then make the faster heterotrophicy bacteria speed breeding of value-added speed, inhibit the breeding of nitrobacteria instead, make
Nitrifier cannot get advantage, can not form population effect.
5. standing 10~48h using effect more preferably after the application dilution, this is because the nitrobacteria metabolism period is longer, put down
For when be more than 10h or more, standing is in order to breed nitrobacteria, to form population advantage.
6. the preferred water-soluble phosphorus of the application is potassium pyrophosphate or sodium pyrophosphate, the predominantly aqueous solution of pyrophosphate is alkali
Property, the growth of nitrobacteria is related with pH, and optimum pH is 7.8, and pyrophosphate has stable pH buffer capacity, Ke Yigeng
Good provides stable pH environment to nitrobacteria growth, is conducive to the growth of nitrobacteria.
