Embodiment 1

[0015] For two groups of solutions containing sodium nitrite at a concentration of 5 mg / L, at a temperature of 30°C, and with a pH value of 7.0, one of them was sprinkled with a biological agent (HSB preparation) for degrading nitrite at a ratio of 1:1000, and the other Group then does not add anything, and they are all placed under natural conditions for 25 hours; Adopt the nitrite determination method of national standard GB / T5009.33-2008 to measure the nitrite content result: the sodium nitrite sprinkled into the preparation solution The concentration has been far less than 0.1mg / L, and no sodium nitrite content has been detected. Then, the larval fish experiment was carried out in the liquid treated with the HSB preparation, and the result was that the fish could live very lively and healthy.

Embodiment 2

[0017] For two groups of solutions containing nitrite concentration of 51mg / L, temperature at 30°C, and pH value of 7.0, one of them was sprinkled with the biological agent (HSB preparation) for degrading nitrite at a ratio of 1:100, and the other Group then does not add anything, they all place 25 hours under natural conditions; Adopt the nitrite determination method of GB / T5009.33-2008 to measure the nitrite content result in the same way: the sodium nitrite sprinkled into the preparation solution The concentration is 0.1mg / L.

Embodiment 3

[0019] For two groups of solutions containing nitrite concentration of 2000mg / L, temperature at 30°C, and pH value of 7.0, one of them was sprinkled with the biological agent (HSB preparation) for degrading nitrite at a ratio of 1:10, and the other The group did not add anything, they were all placed in the natural air for 5 days and 12 days, and the nitrite content was measured by the nitrite determination method of GB / T5009.33-2008. The result was: the nitrite sprinkled into the preparation solution The sodium concentration was 88mg / L after 5 days and less than 0.1ml / L after 12 days.

Abstract

The present invention relates to a method for degrading and converting nitrite by a biological preparation composed of microorganisms (haitobacter sufflavus Tjh-w37), biological enzymes and growth factors; it is characterized in that the microorganisms (haitobacter sufflavus Tjh-w37) and their enzymes grow in the corresponding The rapid growth in the factor has the special effect of degrading and converting nitrite. The invention has the advantages of convenient and fast use, low cost and wide application range. After use, it can not only degrade and transform nitrite, but also decompose and transform organic pollutants and toxic substances in water bodies and sludge, purify water quality, and form a benign micro-ecological balance in water bodies. When using the preparation, sprinkle the preparation directly into the object to be treated, no special facilities are required, under certain temperature, pH and aerobic conditions, after a period of time, the nitrite will be degraded and transformed into non-toxic things.

Description

technical field [0001] The invention relates to a method for degrading and converting nitrite by microorganisms, biological enzymes and inorganic salt growth factors, which can be used in sewage treatment, aquaculture, and water treatment projects in flowing water systems, and belongs to the technical field of sewage treatment by microorganisms and enzymes. technical background [0002] The pure product of nitrite is a white or yellowish crystal, some are granular powder, odorless, slightly salty taste, easy to deliquescence, soluble in water. It can be used in industries such as dye production and surface treatment of some organic synthetic metals. Some construction sites are also used as antifreeze during winter construction. It is also used as a food colorant and preservative in food production. Generally speaking, the content of nitrite that is harmful to the human body is: a one-time intake of 0.2-0.5 grams can cause poisoning (poisoning dose), and a one-time intake of...
