Problems solved by technology

[0002] For wastewater treatment, it is easier to treat low-concentration sewage, but when dealing with high-concentration sewage, the efficiency of microbial treatment will be greatly reduced
In the prior art, in the process of treating sewage with complex bacterial flora for high-concentration sewage treatment, because the living conditions are not all optimal for each strain of the flora, the growth rates of various strains are not the same, resulting in complex The imbalance of the proportion of each strain in the bacterial flora will affect the application effect
In addition, the stability of the complex bacterial flora used in sewage treatment in the prior art is relatively poor, and it is easily affected by the environment an

Embodiment 1

[0022] A special bacteria group for sewage treatment of the present invention comprises 12% by mass percentage of Pseudomonas aeruginosa, 15% of Bacillus, 8% of Rhodococcus, 5% of Acinetobacter, 10% of Pseudomonas aeruginosa, and Alcaligenes 20%, Lactobacillus acidophilus 4%, Streptomyces 6%, Coral Nocardia 20%.

[0023] The method for cultivating special flora for sewage treatment comprises the following steps:

[0024] 1) Each strain is activated and expanded respectively; the medium required for cultivation is: 0.5wt% biotin, 2wt% soybean peptone, 1wt% glucose, 0.5wt% vitamin B1, MnCl 2 4H 2 O 0.5wt%, NaH 2 PO 4 0.5wt%, FeC 6 h 5 o 7 ·5H 2 O 0.5wt%, the balance is water, and the medium is sterilized at 125°C for 30 minutes.

[0025] 2) The strains after the expanded culture were inoculated into the mixed culture medium with different qualities: Pseudomonas aeruginosa 0.60kg, Bacillus 0.75kg, Rhodococcus 0.40kg, Acinetobacter 0.25kg, Pseudomonas aeruginosa Bacillus...

Abstract

The invention relates to a special flora for sewage treatment. The special flora is prepared from the following components in percentage by mass: 10 to 15 percent of pseudomonas aeruginosa, 13 to 20 percent of bacillus, 5 to 10 percent of rhodococcus sp, 3 to 8 percent of acinetobacter, 8 to 15 percent of bacillus pyocyaneus, 15 to 21 percent of bacillus alcaligenes, 3 to 5 percent of lactobacillus acidophilus, 1 to 6 percent of Streptomyces and 10 to 25 percent of coral nocardia, wherein the mass sum of the strains is 100 percent. A cultivation method for the special flora for the sewage treatment, disclosed by the invention, has the advantages of simple operation and broad conditions; the special flora has better treatment effects on sulfate, organic matters and sewage with higher content of NH3-N; the treated sewage which meets relevant national emission standards can be directly discharged or recycled; besides, the special flora has the advantages of low sludge quantity, zero secondary pollution, stable treatment effect, environment friendliness and zero toxicity.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment special bacteria group and a cultivation method thereof. Background technique [0002] For wastewater treatment, it is easier to treat low-concentration sewage, but when dealing with high-concentration sewage, the efficiency of microbial treatment will be greatly reduced. In the prior art, in the process of treating sewage with complex bacteria flora for high-concentration sewage treatment, because the living conditions are not all optimal for each strain of the flora, the growth rates of various strains are not the same, resulting in complex The imbalance of the proportion of each strain in the bacterial flora will affect the application effect. In addition, the stability of the complex bacterial flora used in sewage treatment in the prior art is relatively poor, and it is easily affected by the environment and the population structure, causing the d...
