preparation example Construction

[0042] According to yet another embodiment of the present invention, a method for preparing the above-mentioned composite microorganism is provided, comprising the steps of:

[0043] Single-strain fermentation of Rhodospirillum, Thiobacillus denitrificans and Saccharomyces respectively;

[0044] The composite microorganisms are obtained by mixing raw materials including fermented Rhodospirillum, Thiobacillus denitrificans and yeast.

[0045] It can be understood that the composite microorganism raw material may also contain trace elements and carriers. At this time, the composite microorganisms are obtained by mixing the trace elements and carriers with the fermented Rhodospirillum, Thiobacillus denitrificans and yeast.

[0046] The above-mentioned Rhodospirillum, Thiobacillus denitrificans and yeast are all preferably extracted from the sediment of high ammonia nitrogen water body. The method of described extraction preferably comprises:

[0047] Take the sediment of high a...

Embodiment 1

[0053] A compound microorganism for efficiently degrading ammonia nitrogen comprises the following components in percentage by weight: 30% of TC bacteria J, 20% of TC bacteria F, 15% of TC bacteria M, 5% of specific trace elements, and 30% of carriers.

[0054] Wherein, the above-mentioned TC bacteria J is Rhodospirillum, TC bacteria F is Thiobacillus denitrificans, and TC bacteria M is yeast;

[0055] Specific trace elements include: potassium dihydrogen phosphate 15%, magnesium sulfate 15%, sodium acetate 15%, ferrous sulfate 15%, sodium silicate 40%, mixed according to mass percentage;

[0056] The carrier is amino polysaccharide, which is a biosynthetic natural polymer with a molecular weight between 1,000,000-2,000,000 and a degree of deacetylation as high as 80%. 1→4) The glycoside chains are connected with each other.

[0057] The preparation method of above-mentioned composite microorganism is as follows:

[0058] S1. Screened from the sediment of high ammonia nitrog...

Embodiment 2

[0084] Repeat Example 1, the difference is that the compound microorganisms that efficiently degrade ammonia nitrogen include the following components in percentage by weight: TC bacteria J 40%, TC bacteria F 30%, TC bacteria M 10%, specific trace elements 5%, carrier 15% .

[0085] Wherein, the above-mentioned TC bacteria J is Rhodospirillum, TC bacteria F is Thiobacillus denitrificans, and TC bacteria M is yeast;

[0086] Specific trace elements include: potassium dihydrogen phosphate 14%, magnesium sulfate 16%, sodium acetate 14%, ferrous sulfate 16%, sodium silicate 40%, mixed according to mass percentage;

[0087] The rest of the conditions remained unchanged, and the composite microorganism was prepared.

[0088] Add the above-mentioned composite microorganisms into the water body with high ammonia nitrogen in an amount of 15 ppm.

Abstract

The invention discloses a compound microorganism capable of efficiently degrading ammonia nitrogen. The compound microorganism is prepared from, in parts by weight, 30-50 parts of rhodospirillum, 20-40 parts of thiobacillus denitrificans and 10-20 parts of saccharomyces. The compound microorganism can effectively improve indexes such as ammonia nitrogen, nitrite and hydrogen sulfide in water bodies, improve self-cleaning capacity of the water bodies and purify water. The invention also discloses a preparation method and an application of the compound microorganism.

Description

technical field [0001] The invention relates to the technical field of water treatment. More specifically, it relates to a compound microorganism for efficiently degrading ammonia nitrogen, its preparation method and application. Background technique [0002] With the continuous progress and development of human industry, life, agriculture and other fields, the corresponding discharge and pollution are also increasing, and excessive waste pollution enters the water environment, causing serious damage to the water body ecology. Excessive nitrogen-containing organic matter is the main cause of eutrophication in water bodies, which seriously harms the ecological balance of water bodies and human health. At present, nitrogen pollution in China mainly comes from the following two sources: non-point source pollution during the application of nitrogen fertilizers, and point source pollution caused by industrial nitrogen-containing wastewater discharge. A large amount of nitrogen-...
