Embodiment Construction

[0017] The technical features of the present invention will be further elaborated below in conjunction with specific implementation examples.

[0018] 1) The compound ecological deodorant includes a porous adsorption carrier and deodorizing microbial strains. After the screened high-efficiency microbial strains are activated on a slope, they are inoculated into liquid medium and placed in a constant temperature shaker incubator. Under constant temperature conditions of 30°C and 220 r / min, the liquid bacterial liquid was obtained by culturing for 3-7 days. Mix the liquid bacterial solution and the porous adsorption carrier according to the ratio of 1.2:1 and stir evenly, put it in a sterile container and ferment it at 30 ℃ for about a week, and then it will become a deodorant product.

[0019] See Table 1-1 for strain identification results:

Abstract

The invention discloses an ecological deodorant for stink gas control and a using method thereof, particularly provides a technology of stink gas control in conveying and treating trash, sludge, dejection and the like, and belongs to the field of environmental protection. The composite ecological deodorant for stink gas control is compounded from a porous adsorption carrier with strong adsorption capability and a deodorizing microorganism strain, and is characterized in that: the ratio of the porous adsorption carrier to the deodorizing microorganism strain is (1-1.3):1 according to weight parts, wherein the porous adsorption carrier at least comprises hulls or peels falling from paddy of bran and kernels of wheat or millet; the deodorizing microorganism strain is derived from one or combination of alcaligenes faecalis, achromobacter, bacillus, algicidal bacteria, caryophanon and the like. The technology is simple and feasible, economical and environmentally-friendly, high in efficiency and low in consumption, and has practical application value in controlling various stink gases.

Description

technical field [0001] The invention discloses an ecological deodorant for malodorous gas control and its use method, specifically a kind of malodorous gas control in the transportation and treatment of garbage, sludge and feces. The technology belongs to the field of environmental protection. Background technique [0002] Sludge, garbage disposal, and waste from chemical, food, slaughtering and other industries decompose and decompose organic matter, and the odorous substances produced are highly irritating and toxic, which have a serious impact on the environment and human health. With the development of society and the enhancement of people's awareness of environmental protection, people have put forward higher requirements for the quality of the air environment and are more sensitive to the problem of odor. Due to the pollution of foul-smelling gas, conflicts and disputes between surrounding residents and production enterprises often occur. In the United States, odor i...
