Preparation method of special biological deodorant used for sewage deodorization

Abstract

The invention relates to a preparation method of a biological deodorant used for sewage deodorization. The biological deodorant comprises a deodorant component and an extract product component according to a mass ratio of 1:1, wherein the deodorant component comprises, by mass, 20-40% of Lactobacillus plantarum, 20-40% of beer yeast, 1-5% of actinomycetes, 1-5% of bacillus and 5-10% of Enterococcus faecalis; the extract product component comprises, by mass, 1-3% of lactic acid, 0.5-1% of citric acid, 0.02-0.05% of sodium benzoate, 1.5-2% of a natural plant extract product and 90-95% of water; and the natural plant extract product comprises, by mass, 10-20% of a ginkgo extract product, 10-20% of a Radix Sanguisorbae extract product, 20-30% of a mint extract product, 15-25% of a Lagerstroemia indica extract product and 15-20% of a sweet-scented osmanthus extract product. The preparation method of the biological deodorant used for sewage deodorization has the advantages of low cost, high efficiency, wide adaptation and high practicality in concrete production.

Description

technical field [0001] The invention relates to a preparation method of a biological deodorant specially used for sewage deodorization. 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, affect the working and livi...

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.
