preparation example Construction

[0042] The present invention also provides a method for preparing a multifunctional biologically active material, comprising the following steps:

[0043] In step 1, the compound flora is expanded and cultured to obtain the spore powder of fungi HD-2 and LW-1, bacteria T3, GYH, SY1, byf-5 and Lactobacillus sp. The concentrated bacterial liquid is obtained after mixing to obtain a complex bacterial flora solution;

[0044] In step 2, the bamboo-charcoal composite material is prepared by utilizing a Wally beater, a defragmenter and a sheet former;

[0045] Step 3, put the bamboo-charcoal composite material into the composite flora solution and soak it, turn it over every 3-5h, and repeat it for 3 to 5 times;

[0046] Step 4, take out the bamboo-charcoal composite material that adsorbs the composite flora;

[0047] Step 5, put the bamboo-charcoal composite material adsorbing the composite flora into a vacuum drying oven at 30° C. to dry for 24-48 hours, that is, multifunctiona...

Embodiment 1

[0066] Example 1: Preparation process of multifunctional bioactive material 1

[0067] In the present invention, the multifunctional biologically active material 1 is composed of a complex flora and a novel degradable load carrier. The specific process is as follows:

[0068] ①Compound flora: bacteria T3, GYH, SY1 and byf-5, lactic acid bacteria Lactobacillus sp. The slanted sides of the seed test tubes were respectively inoculated into the corresponding liquid medium, and cultured with shaking in a shaker at a temperature of 32°C. The inoculum was obtained after culturing for 5 days. The inoculum was inoculated into a fermenter containing an inorganic salt liquid medium for high-density culture, and the corresponding carbon source was continuously supplied in a fed-feed manner. The temperature, pH and dissolved oxygen concentration were adjusted by on-line monitoring. After culturing for 3 days, a large number of bacterial cells were obtained, which were enriched by cent...

Embodiment 2

[0072] Example 2: Multifunctional bioactive material 1 purification of malodorous waste gas

[0073] The multifunctional bioactive material 1 and its module 3 were prepared by the method described in Example 1, the obtained module 3 was loaded into a bioreactor, and the H-containing 2 S and methyl sulfide are mixed with waste gas, and water is sprayed for 10 minutes every 8 hours to ensure that the multifunctional bioactive material 1 is in a wet state. After 1 day of operation, for 50mg / m 3 H 2 S and 80mg / m 3 The removal effect of methyl sulfide was more than 85%, indicating that the complex flora in the active material had been successfully activated. After that, the device was treated with different concentrations of H 2 The mixed waste gas of S and methyl sulfide was investigated, and the results were as follows image 3 shown. The results show that the odor purification device filled with multifunctional bioactive material 1 is effective for 50-250 mg / m 3 H 2 S an...

Abstract

The invention discloses a multifunctional bioactive material as well as a preparation method and application thereof, and aims to provide a multifunctional bioactive material which is used for biological purification and is not easy to cause secondary pollution as well as a preparation method and application thereof. The invention relates to a microbial inoculum for degrading bacillus amyloliquefaciens, which is composed of a composite flora and a novel degradable load carrier, the composite flora is loaded on the novel degradable load carrier, the composite flora is mainly composed of Rhizobium radiobacter T3 (CCTCC NO.M 2011105), Stenotrophomonas maltophiliaGYH (CCTCC NO.M 20191025), Alkaligenes sp.SY1 (CCTCC NO.2014619), Aspergillus fumigatus HD-2 (CCTCC NO.M 2014175), Trichoderma virideLW-1 (CCTCC NO.M 2014176), and Bacillus amyloliquefaciens byf-5 (CCTCC NO.M 20818), and the composite flora is mainly composed of Rhizobium The method has the beneficial effects that the biological membrane forming period is shortened, the concentration of characteristic degrading bacteria in a unit material is high, and the odor purification effect is good; the biological purification process of the odor is greener and safer, and the purpose that secondary pollution is not easily caused by biological purification is achieved.

Description

technical field [0001] The present invention relates to the related technical field of biologically active materials, in particular to a multifunctional biologically active material, a preparation method and applications thereof. Background technique [0002] In recent years, with the rapid development of large-scale livestock and poultry breeding and the continuous and in-depth improvement of rural living environment improvement, the control of odor pollution in livestock and poultry farms has become an urgent requirement to improve the production and living environment in rural areas. The odor pollution of livestock and poultry farms mainly comes from ammonia (NH) gas generated by the decomposition of organic matter such as livestock and poultry houses and manure. 3 ), hydrogen sulfide (H 2 S), volatile odorous organic compounds, etc., not only the smell is disgusting, but also accompanied by pathogenic microorganisms, suspended particles, parasite eggs and other toxic a...
