Improved denitrifying bacterium, codonopsis pilosula, lagerstroemia indica and nostoc containing composite microbial deodorant

Abstract

The invention relates to an improved denitrifying bacterium, codonopsis pilosula, lagerstroemia indica and nostoc containing composite microbial deodorant. The improved denitrifying bacterium, codonopsis pilosula, lagerstroemia indica and nostoc containing composite microbial deodorant comprises a microbial inoculum, a plant extract, an alga extract and water, wherein the microbial inoculum comprises 20-40% of lactobacillus plantarum, 20-40% of beer yeast, 1-5% of improved denitrifying bacterium, 1-5% of improved nitrifying bacterium and 1-5% of azotobacter chroococcum; the plant extract comprises 5-10% of a pine needle extract, 5-10% of a codonopsis pilosula extract and 10-20% of a lagerstroemia indica extract; the alga extract is 0.5-2% of a nostoc broken-wall extract; all the percentages are percentages by mass. The improved denitrifying bacterium, codonopsis pilosula, lagerstroemia indica and nostoc containing composite microbial deodorant is low in cost, high in efficiency, wide in adaptability, and very practical in the specific production.

Description

technical field [0001] The invention relates to a composite microbial deodorant with improved denitrifying bacteria Codonopsis crape myrtle and Nostoc algae. Background technique [0002] With the progress of society, economic development, enhancement of people's environmental awareness and continuous improvement of quality of life, more and more attention has been paid to the control and treatment of malodorous gases. The gas is mainly some sulfur-containing compounds and nitrogen-containing compounds, such as hydrogen sulfide, methyl mercaptan, sulfide, ammonia, etc., which have a strong pungent odor and are extremely harmful to the human body. They can pass through the respiratory tract, eyes, skin, etc. It enters the human body through different channels, making people dizzy and uncomfortable, and being exposed to it for a long time will greatly damage the nervous system of the human body. The malodorous gas will not only corrode the equipment in the factory area, affec...

Problems solved by technology

The adsorption method includes acid-base potion washing and activated carbon adsorption. The former needs to consume a large amount of chemicals, while the latter is easy to block, frequent replacement, and high maintenance costs; the combustion method is suitable for organic waste gas with high concentration and high calorific value. In general deodorization It is rarely used in engineering; the direct emission of ozone generated by the high-energy ion method may endanger environmental safety, and the ions produced by it have a strong oxidation effect, corrode the equipment, and have certain harm to the human body; biological methods include biological Filter towers, as well as biological deodorants, generally cost less. The former requires debugging time, while the latter requires more complicated cultivation conditions to have an efficient deodorizing effect.
