Abstract
The invention belongs to the technical field of aquiculture, and particularly relates to a method for reducing nitrite in aquiculture water bodies, which includes the following steps: 0.1g/m<3> to 2g/m<3> of citric acid or 0.1g/m<3> to 2g/m<3> of sulfamic acid is used for treating an aquiculture water body, so that the pH value of the aquiculture water body is regulated to 7.5 to 8.0; after an interval of two hours, 0.1g/m<3> to 1g/m<3> of potassium peroxymonosulfate or 0.1g/m<3> to 1g/m<3> of potassium ferrate is used for treating the aquiculture water body; after an interval of three to five hours, 0.1g/m<3> to 1g/m<3> of sodium hypophosphite is used for treating the aquiculture water body. The main components used by the method are chemical substances, the conventional reduction-oxidation reaction is utilized to reduce the content of nitrite, consequently, the situation of poor using effect in oxygen-deficient water bodies which is common at the middle and later stages of aquiculture is prevented, and the denitrification problem of water bodies at the middle and later stages of aquiculture is effectively solved.
Description
Technical field
The invention belongs to technical field of aquaculture, especially relate to a kind of method reducing aquaculture system nitrite.
Background technology
In normal aquaculture system, the organic substance such as residual bait, ight soil of aquatic animal under the environment of aerobic, is converted into harmful nitrite by nitrite bacteria, and then under aerobic conditions, be further converted to harmless nitrate by nitrobacteria, the nitrate transformed is absorbed by the algae in water body, thus completes optimum substance metabolism circulation.
But continuing to increase in recent years along with cultivation density, especially cultivate middle and later periods daily ration, feeding quantity and continue to increase, Organic substance in water matter content severe overweight, beyond the bearing capacity of water body own metabolism.Nitrite bacteria and nitrobacteria consume the dissolved oxygen in water body gradually, because the microorganism of being responsible for decomposing organic matter matter mostly generally is aerobic microorganism, the dissolved oxygen (DO) of water body of a specified duration constantly declines, thus suppress quantity and the reproduction speed of aerobic microbiological further, the nitrite content in aquaculture water finally can be caused constantly to raise, cultivated animals pathological hypoxic will be caused when nitrite content reaches certain numerical value, the speed of growth slows down, physique declines, and even causes disease; Will acute poisoning be caused time too high, cause and drop in production over a large area.
Main product main component is nitrobacteria or denitrifying bacterium on the market is at present the product of main component, in theory, nitrifier and denitrifying bacteria can reduce nitrite content, but because they are chemoautotrophic bacterias, growth and breeding speed is slow, want could breed a generation in more than 20 hours, add mushroom Techniques of preserving, throw in after affect to each side such as water body surviving rate height, water body environment, cause nitrifier and denitrifying bacteria degrading nitrite is undesirable.The more important thing is, if the words denitrification of dissolved oxygen deficiency in water body can more easily occur, denitrification may be nitrite nitrate reduction, makes nitrite increase in the regular hour on the contrary, so the said products exists very large defect.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of simple and convenient, effectively solve the method for the reduction aquaculture system nitrite of cultivation later stage water body denitrification problem.
For solving the problem, the technical scheme that invention adopts is: a kind of method reducing aquaculture system nitrite, comprises the following steps:
(1) 0.1-2g/m is used
3citric acid or 0.1-2g/m
3thionamic acid process aquaculture water, is adjusted to 7.5-8.0 by the pH value of aquaculture water;
(2) after step (1) process, after the 2h of interval, 0.1-1g/m is used
3potassium hydrogen peroxymonosulfate or 0.1-1g/m
3potassium ferrate process aquaculture water;
(3) after step (2) process, after the 3-5h of interval, 0.1-1g/m is used
3inferior sodium phosphate process aquaculture water.
Preferably, described potassium hydrogen peroxymonosulfate using dosage is 0.4-0.6g/m
3.
Preferably, described potassium ferrate using dosage is 0.4-0.6g/m
3.
Preferably, described inferior sodium phosphate using dosage is 0.3-0.5g/m
3.
Advantage of the present invention and positively effect are: the main component that the present invention uses is chemical substance, conventional redox reaction is utilized to reduce nitrite content, avoid in the not good situation of cultivation middle and later periods ubiquity water hypoxia result of use, efficiently solve the Denitrogenation of cultivation middle and later periods water body.
