Embodiment 1
[0026] A treatment process for flue gas produced in the amino acid preparation process, the process comprises the following steps:
[0027] 1) Preparation of chemical preparations:
[0028] Get 4 parts of diatomite according to weight, 3 parts of chitosan, 2 parts of potassium humate, 1 part of gac, 1 part of peat soil, 10 parts of ammonia water, standby; Diatomite, chitosan, potassium humate, Activated carbon, and peat soil, mixed evenly, ground into a powder with a particle size of 100 mesh, then added ammonia water, and centrifuged at 100 rpm for 30 minutes to obtain the product;
[0029] 2) Preparation of microbial preparations:
[0030] It is made by mixing the raw material bacteria in the following volume percentages: 30% Nitrosoma, 30% Paracoccus denitrificans, 20% Alcaligenes faecalis, and 20% Bacillus cereus; the original concentration of the above four bacteria is 1× 10 8 a / ml;
[0031] Described nitrosative bacteria are specifically nitrosative bacteria ( Nitro...

[0043] 3) Dust removal, fog removal, desu...
Embodiment 3
[0048] Flue gas purification effect test: choose the boiler flue gas prepared by our company to prepare amino acids, and use the process of Example 1 to treat it. The units of various pollutants are mg / Nm 3 , the specific results are shown in Table 1:
[0049] Table 1
[0050] pollutant type NOx SO 2 soot before processing 497 1138 156 after treatment 16 43 3
[0051] Conclusion: After treatment, the concentration of various pollutants is greatly reduced, fully complying with the emission standards.
