Embodiment 1

[0031] A preparation for the treatment of sewage containing trinitrotoluene, the active ingredient of the preparation includes the following raw materials in weight percentage:

[0032] Nitrosogenic bacteria 20%, Bacillus subtilis 20%, Alcaligenes faecalis 15%, Pseudomonas aeruginosa 10%, Saccharomyces cerevisiae 10%, Rhodococcus 10%, Bacillus megaterium 10%, Aspergillus niger 5%.

[0033] Among the above bacteria agents:

[0034] The nitrosogenic bacteria are preferably Nitrosomonas europaea CCTCC No: M2010002;

[0035] The Bacillus subtilis is preferably Bacillus subtilis (Bacillus subtilis) CGMCC No: 0954;

[0036] The Alcaligenes faecalis is preferably Alcaligenes faecalis ATCC 31555;

[0037] The Pseudomonas aeruginosa is preferably Pseudomonas aeruginosa ATCC 15442;

[0038] The Saccharomyces cerevisiae is preferably Saccharomyces cerevisiae CCTCC No: M208110;

[0039] The Rhodococcus is preferably Rhodococcus (Rhodococcus rhodochrous) ATCC15906;

[0040] The Bacillus...

Embodiment 2

[0055] The use method of the microbial solid preparation of the present invention: put the solid preparation into the polluted water body of trinitrotoluene, wherein the weight ratio of the solid preparation and the water body is 1:1000, wherein the polluted water body of trinitrotoluene is artificially prepared, and the trinitrotoluene The initial concentration of trinitrotoluene was 36.65 mg / L, and after 24 hours of shaking culture at room temperature, the concentration of trinitrotoluene dropped to 0.0 mg / L, and the degradation rate could reach 100%.

Embodiment 3

[0057] The solid bacterial agent prepared in Example 1 is used to treat certain high-trinitrotoluene-containing industrial wastewater, and 15 grams of the preparation prepared in Example 1 are added per cubic meter of sewage, once a day, and continuously added twice After one week, the processing effect of detection is as follows:

Abstract

The invention relates to a preparation for trinitrotoluene-contained sewage treatment and a using method of the preparation. The preparation is formed of raw materials, by weight, 20% of nitrosobacteria, 20% of bacillus subtilis, 15% of alcaligenes faecalis, 10% of pseudomonas aeruginosa, 10% of brewer's yeast, 10% of rhodococcus fascians, 10% of bacillus megatherium and 5% of aspergillus niger. Various raw materials of the preparation are reasonably prepared and symbiotically coordinated without antagonism, and accordingly, the preparation is applicable to industrial sewage treatment, treatment quality and treatment water quality can be improved, running cost can be reduced and discharge up to standards is promoted.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a bacterial agent for repairing trinitrotoluene-containing sewage treatment and a method for using the same. Background technique [0002] TNT (2, 4, 6 trinitrotoluene) is currently the most productive production explosive. In recent years, the manufacture, processing and packaging of TNT in ammunition workshops have caused highly concentrated pollution in the soil, and will eventually lead to groundwater pollution. Long-term exposure to nitrotoluene increases the risk of anemia and abnormal liver function. Blood and liver effects, enlarged spleens, and other adverse effects on the immune system were also found in animals injected or inhaled. There is also evidence that TNT has adverse effects on male reproductive function, and TNT is also listed as a possible carcinogen. Therefore, many countries have strictly restricted the emission standards of trinitrotol...
