Abstract
The present invention discloses a method for removing nitrite and ammonia nitrogen in the aquatic product culture. The method comprises the following steps that hydrogen peroxide is filled in an opening container, and an osmotic layer is covered at an opening of the container; subsequently, the container filled with the hydrogen peroxide is immersed in a culture pond and is fixed on an oxygen enriching machine in the culture pond; the oxygen enriching machine is started to make the hydrogen peroxide slowly diffused by the water flow, and the hydrogen peroxide is decomposed into water and oxygen in the process of diffusing so that the decomposed oxygen simultaneously makes the nitrite and the ammonia nitrogen oxidized into nitrate; and finally, cultured photosynthetic bacteria are sprinkled in the culture pond, and consequently, the nitrate is absorbed and used by the photosynthetic bacteria, etc. The nitrite and the ammonia nitrogen in the aquatic product culture can be rapidly removed by the method, and additionally, the method has long effect sustaining time and no recurrence. Furthermore, the residual substance does not exist after use so that the method does not have the adverse effect on the animal in the aquatic product culture and the growth of the floating algae.
Description
Technical field
The present invention relates to a kind of method of removing nitrite and ammonia nitrogen in the water, particularly a kind of method of removing nitrite and ammonia nitrogen in the aquaculture.
Background technology
At present, the water quality regulation of pond aquaculture mainly relies on the self-cleaning of water body, and change water and mechanical enhancement, but because the pond eutrophication aggravation that highdensity breed bait throwing in fertilising causes, thereby cause nitrite, ammonia-nitrogen content to exceed standard, when nitrite, will cause the aquatic animal mass mortality when ammonia-nitrogen content exceeds standard, directly influence the economic benefit and the human beings'health of culture fishery, culture the major issue that the owner has a headache most thereby become, and pond water quality only relies on self to regulate and is difficult to the aquaculture ecotope that keeps good.Development along with water technology, nitrite, the utilization in ammonia nitrogen of water technology in removing aquaculture obtains promoting gradually, at present the utilization water technology remove nitrite, ammonia nitrogen in the aquaculture method mainly contain physisorphtion, chemical method and biological process, these methods have certain effect for the removal of nitrite in the aquaculture and ammonia nitrogen, yet these methods exist certain defective again in the utilization process.The treatment capacity of physisorphtion is limited, and easily bounce-back; Some chemical substance strong toxicity when the utilization chemical process is handled aquatic animal and planktonic algae are had very strong lethal effect, and residual quantity is big; Biological treatment is slow excessively for the removal speed of the nitrite of high density.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of method of removing nitrite and ammonia nitrogen in the aquaculture, it can remove nitrite and ammonia nitrogen in the aquaculture fast, efficiency time is long, be difficult for bounce-back, and do not have residually after using, the growth of aquatic animal and planktonic algae is had no adverse effects.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of method of removing nitrite and ammonia nitrogen in the aquaculture, this method comprises the steps: in order
(1). hydrogen peroxide is packed in the open containers, and vessel port place covers a pervious course, the container that hydrogen peroxide is housed is immersed in cultures in the pond and be fixed on the oxygenating machine of culturing in the pond;
(2). start oxygenating machine, hydrogen peroxide is spread by sluggish flow, decomposing hydrogen dioxide solution is water and oxygen in diffusion process, and the oxygen of decomposition is oxidized to nitrate with nitrite and ammonia nitrogen simultaneously:
(3). the photosynthetic bacterium of splashing and cultivating in culturing the pond makes nitrate absorb by photosynthetic bacterium.
For hydrogen peroxide slowly and is constantly spread, the open containers of splendid attire hydrogen peroxide can adopt the wide-mouth bucket, and at opening part covering one deck pervious course of wide-mouth bucket, pervious course can adopt sponge or the bigger material of other void ratio.
Ultimate principle of the present invention is such: the present invention adopts chemistry to combine with biological method, utilizing strong oxidizer---hydrogen peroxide discharges slowly and spreads under the current that oxygenating machine stirred and comes, in diffusion process, be decomposed into water and oxygen, the oxygen that decomposes is oxidized to nitrate with nitrite and ammonia nitrogen, after three days to culturing the pond photosynthetic bacterium of splashing, nitrate is absorbed by photosynthetic bacterium as nutritive substance, thereby reaches the purpose of removing nitrite and ammonia nitrogen.
Photosynthetic bacterium of the present invention can obtain with following method:
One, the photosynthetic bacteria culture medium prescription is (unit be weight percentage %): ammonia chloride 0.08-0.15, Sodium n-caproate 0.20-0.35, DL-oxysuccinic acid 0.05-0.10, sodium hydroxide 0.20-0.30, dipotassium hydrogen phosphate 0.08-0.15, magnesium chloride 0.01-0.02, calcium chloride 0.01-0.02, yeast extract paste 0.05-0.1, distilled water 99.32-98.81;
Two, cultural method: the pH value of substratum is transferred to 7.2-7.5, so 120 ℃ following high-temperature sterilization 20-30 minute, cooling back adds 10% bacterial classification (volume ratio), 25-30 ℃ of following anaerobism illumination cultivation 6-8 days, obtains wine-colored liquid photosynthetic bacteria liquid.
Compare with the water quality that contrasts the pond using test of the present invention to culture the pond, control methods is as follows: test tank (1) area is eight mu, 1.2 meters of the depth of waters; 5 mu of test tank (2) areas, 1.3 meters of the depth of waters; Six mu of test tank (3) areas, 1.1 meters of the depth of waters; Test tank discharges hydrogen peroxide by 3 kilograms/mu consumption, throws in photosynthetic bacterium after three days, and consumption is 1.5 kilograms/mu, six mu of contrast pool areas, 1.1 meters of the depth of waters.Continuous five days synchronous Analysis Results of Water Quality as table 1,2,3,4, shown in.
