Embodiment 1

[0035] Take 10 parts of bacterial species Bacillus subtilis AX1, 15 parts of Bacillus amyloliquefaciensAX2, 10 parts of Bacillus thuringiensis AX3, 10 parts of Bacillus licheniformis AX4, 15 parts of Bacillus cereus AX5, and 15 parts of Lactobacillus acidophilus AX6 by weight, mix and inoculate in liquid medium, Shake culture at 30-40°C 120-180rpm for 16h-18h, and expand the culture. Using sawdust as a carrier, the expanded bacterial solution is immobilized and made into a solid treatment bacterial agent for use.

[0036] Reference attached figure 1 , fill the fixed bacteria into the hollow mesh ball, then put the filled ball into the deodorization device, and start the food waste treatment equipment.

[0037] Collect exhaust gas at the air outlet, and test the collected exhaust gas with reference to the GB14554-93 odor pollutant discharge standard. The test results are shown in the table below, which meets the requirements of the standard.

Embodiment 2

[0040] Take 15 parts of strains Bacillus subtilis AX1, 20 parts of Bacillus amyloliquefaciensAX2, 10 parts of Bacillus thuringiensis AX3, 15 parts of Bacillus licheniformis AX4, 10 parts of Bacillus cereus AX5, 10 parts of Lactobacillus acidophilus AX6 by weight, mix, inoculate in liquid medium, 30 Shake culture at -40°C at 120-180rpm for 16h to 18h, and expand the culture. Using sawdust as a carrier, the expanded bacterial solution is immobilized and made into a solid treatment bacterial agent for use.

[0041] Reference attached figure 2 As shown, fill the fixed bacteria into non-woven fabric or other fine air-permeable bags, then seal the filled bags, place them in the deodorizing device, and start the food waste treatment equipment.

[0042] Collect exhaust gas at the air outlet, and test the collected exhaust gas with reference to the GB14554-93 odor pollutant discharge standard. The test results are shown in the table below, which meets the requirements of the standard...

Abstract

The invention discloses a microbial agent deodorization microbial agent, a preparation method thereof and a waste gas treatment process. The preparation method comprises the following steps: degradingkitchen waste, enriching dominant flora, separating and comparing all strains, selecting safe dominant strains, and performing combining and compounding to prepare the agent which is used for treating waste gas generated in the microbial metabolism process of organic waste with high efficiency. The composition of tail gas treated by the agent disclosed by the invention completely meets the emission requirement, no odor is released in the whole organic waste treatment process, and the agent is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a microbial deodorizing agent for organic waste tail gas treatment and a preparation method thereof. Background technique [0002] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the garbage generated in the process of urban production and life has also increased rapidly. Domestic garbage occupies land, pollutes the environment, and affects people. Health effects are also becoming more apparent. The massive increase of municipal solid waste has made it more and more difficult to dispose of waste, and the resulting environmental pollution and other issues have gradually aroused widespread concern from all walks of life. [0003] Household waste can generally be divided into four categories: recyclable waste, kitchen waste, hazardous waste and other waste. Commonly u...
