Embodiment 3

[0076] On the basis of Example 1, the air-purifying composite microbial bacterial agent of the present invention further includes a carrier.

[0077] Its preparation method is:

[0078] (1) Prepare the carrier:

[0079] (1) Put clay (80 mesh), hydroxyapatite, activated carbon (250 mesh) and water into the dough mixer according to the mass ratio of 3:2:1:2 and mix evenly; after mixing evenly, put the mixture Put it into the spherical mold and compact it, and take out the spherical carrier blank after 2 minutes, with a diameter of 2cm;

[0080] (2) Put the carrier blank into the kiln after natural drying, heat the blank from room temperature to 370°C at a heating rate of 2°C per minute, and then start from this temperature and sinter at a heating rate of 3°C per minute. After reaching 850°C and keeping it for 1 hour, the sintered body is gradually cooled to 540°C in 30-40 minutes, taken out from the kiln, and then cooled naturally to obtain the carrier.

Abstract

The invention discloses a complex microbial agent capable of purifying air and application thereof. The complex microbial agent is prepared from, by weight, 7-15 parts of pseudomonas, 7-15 parts of saccharomycetes, 6-14 parts of Opitutales, 5-12 parts of rhizobium, 4-12 parts of rhodospirillum, 4-12 parts of rhizopus oryzae, 2-9 parts of micrococcus, 2-8 parts of bacteroides, 2-9 parts of clostridia, 2-8 parts of bacillus cereus, 1-7 parts of alcaligenes, 1-7 parts of streptomycete, 1-7 parts of rhodocyclus, 1-6 parts of galactococcus, 1-6 parts of mycobacteria, 1-6 parts of burkholderiales, 1-6 parts of lysobacter, 1-5 parts of hydrogenophilus, 1-5 parts of xanthomonas, 1-5 parts of brevundimonas, 0.1-3 parts of comamonas and 0.1-3 parts of aspergillus. The complex microbial agent utilizes the synergistic effect of powerful bacteria, it is promoted that microorganisms utilize and perform metabolism decomposition on volatile organic compounds in the air, so that the efficient elimination and reduction of contaminants are achieved.

Description

technical field [0001] The invention discloses the technical field of air purification, and relates to a composite microbial bacterial agent for air purification and its application. Background technique [0002] According to statistics, modern people spend more than 80% of their time indoors, and infants, young children, the elderly, the sick, and the disabled spend more time indoors. Therefore, most of the air that people breathe comes from indoors, and the quality of indoor air directly affects people's health. According to reports, indoor air pollution has caused 35.7% of respiratory diseases, 22% of chronic lung diseases and 15% of tracheitis, bronchitis and lung cancer. Therefore, indoor air pollution has become one of the five most harmful environmental factors to public health. [0003] The main pollutants in indoor air are volatile organic compounds, which mainly come from building and interior decoration materials, combustion products of cooking and smoking, and ...
