Embodiment 1

[0048] Embodiment 1. Preparation of growth-promoting flora

[0049] Bifidobacteria, lactic acid bacteria, actinomycetes and colloidal bacillus were evenly mixed according to the following mass ratios to obtain growth-promoting flora.

[0050] Growth-promoting flora No. 1:

[0051] The mass ratio of bifidobacteria, lactic acid bacteria, actinomycetes and glial bacillus is 1:1:1:3.

[0052] Growth-promoting flora No. 2:

[0053] The mass ratio of bifidobacteria, lactic acid bacteria, actinomycetes and glial bacillus is 1.1:0.8:1.1:2.7.

[0054] Growth-promoting flora No. 3:

[0055] The mass ratio of bifidobacteria, lactic acid bacteria, actinomycetes and glial bacillus is 0.9:1.0:0.9:3.5.

Embodiment 2

[0056] Example 2. Validation of the effect of growth-promoting bacteria on improving the efficiency of waste gas treatment

[0057] 1. Bacteria preparation for waste gas treatment

[0058] (1) Screen the mixture of target flora

[0059] a. Collect 10g of humus soil samples near a chemical plant, mix with 100ml of sterile industrial sewage with a pH of 4-7 from the plant, incubate at 30-45°C, 150r / min for 48h, and then take it out.

[0060] b. Inoculate 10ml of culture solution into 90ml of fresh sterile industrial sewage in the ultra-clean workbench, incubate at 30-45°C, 150r / min for 48 hours, then take it out. The above operation was repeated three times to enrich microorganisms that degrade volatile organic compounds.

[0061] d. Use a sterile pipette to draw 1ml of the enriched bacterial solution, put it into a test tube filled with 9ml of sterile water, shake it evenly, take 1ml of the diluted bacterial solution and mix it with another 9ml of sterile water to dilute, Re...

Embodiment 3

[0103] Example 3. Effect of packing on waste gas treatment efficiency

[0104] 1. Prepare the stuffing

[0105] From volcanic rock, wood blocks, and raw shells, make the stuffing as follows.

[0106] Packing No. 1

[0107] Treatment of volcanic rocks: pickling in pH6 nitric acid solution for 3 minutes, washing with water, and air-drying; then washing with alkali in pH8 sodium hydroxide solution for 3 minutes, then washing with water, and air-drying; Fumigate the volcanic rocks in the high-pressure steam for 2 minutes to remove the residual salt substances on the surface of the volcanic rocks, and screen the volcanic rock particles with a particle size of 10-20 mm and a porosity of 50%.

[0108] Wood block processing: mechanically crush the wood blocks (cannot be cut regularly), sieve after crushing, and select wood blocks with a particle size of 8-16cm and a thickness of 3-5cm. Then use a high-pressure punching gun to impact the wood block with a water pressure of 350Mpa ...

Abstract

The invention relates to the field of the waste gas purification, and specifically relates to a growth promoting flora for improving waste gas treatment efficiency and a waste gas treatment method. The growth promoting flora for improving waste gas treatment efficiency provided by the invention comprises bifidobacterium, lactic acid bacteria, actinomycetes and bacillus mucilaginosus in a mass ratio of 0.9-1.1:0.8-1.0:0.9-1.1:2.7-3.5. The growth promoting flora disclosed by the invention does not directly participate into the pollutant degradation, but can promote the growth and multiplying ofa target flora mixture directly participating into the pollutant degradation, so that the metabolic capacity on a pollutant by the target flora mixture can be always maintained at a high level, and the treatment efficiency on the industrial waste gas reaches up to 99.8% or more.

Description

technical field [0001] The invention relates to the field of waste gas purification, in particular to a growth-promoting bacterial group and a waste gas treatment method for improving waste gas treatment efficiency. Background technique [0002] In recent years, environmental issues have been widely concerned by people, and the harm of organic waste gas has become a consensus today, and the control of organic waste gas pollution is one of the focuses of environmental protection work. Organic waste gas is waste gas produced during the production and processing of petrochemical, rubber, plastic, paint, printing and many other industries. It is characterized by a large amount and contains toxic pollutants, a large part of which is volatile organic compounds (VOCs). Volatile, flammable, foul-smelling and harmful to human health. [0003] At present, there are mainly two types of treatment methods for organic waste gas: one is the recovery method, through physical methods, under...
