specific Embodiment approach 1

[0025] Specific embodiment 1: A compound agent for removing formaldehyde in this embodiment is made of a mixture of composite bacterial agent, vermicompost and foreign insect excrement; wherein, the composite bacterial agent is made of mixed bacterial liquid and biological enzyme according to the mass ratio It is formed by mixing in a ratio of 5 to 10:1; the mixed bacteria solution is mixed with the main bacteria and auxiliary bacteria in a ratio of 2 to 5:1 by mass; the main bacteria are methylotrophic bacteria or pseudo The genus Monas; the auxiliary bacteria are one or more of the genus Bacillus, Aspergillus, and Candida; the mass ratio of the compound bacterial agent to the mixture of vermicompost and foreign insect excrement is 2 to 10:1; vermicompost The mass ratio of vermicompost and foreign insect manure in the mixture with foreign insect manure is 2 to 4:1;

[0026] The compound agent for removing formaldehyde is to mix the mixture of vermicompost and vermicompost wit...

specific Embodiment approach 2

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the Pseudomonas is Pseudomonas alcaligenes, Pseudomonas putida, Pseudomonas amygdala or Pseudomonas fluorescens; The methylotrophic bacterium is Methylobacter extorquens; the Bacillus genus is Bacillus acid fast-growing bacillus or Bacillus cereus; the genus Candida is Candida maltina; Others are the same as in the first embodiment.

specific Embodiment approach 3

[0028] Specific embodiment three: the present embodiment is a kind of preparation method for removing formaldehyde composite agent, and it is carried out according to the following steps:

[0029] 1. After the cultured main bacteria and auxiliary bacteria are uniformly mixed according to the mass ratio of 2 to 5:1, the mixed bacteria liquid is prepared;

[0030] Among them, the main bacteria are methylotrophs or Pseudomonas; the auxiliary bacteria are Bacillus, Aspergillus or Candida;

[0031] The mass ratio of Bacillus in the main bacteria to the auxiliary bacteria is 4-8:3-6; the mass ratio of the Candida in the main bacteria to the auxiliary bacteria is 4-8:2-4; the main bacteria and the auxiliary bacteria The mass ratio of Aspergillus in the genus is 4-8:1;

[0032] 2. After mixing the mixed bacterial solution and the biological enzyme according to the ratio of 2 to 10:1 in mass ratio, a composite bacterial agent is obtained;

[0033]3. After mixing the vermicompost and ...

Abstract

Relating to biological inoculants, the invention relates to a formaldehyde removal composite inoculant, a preparation method and application thereof, and aims to solve the problems of combined utilization of insect dung (earthworm dung) with composite microorganisms to give better play to the two and then remove indoor formaldehyde. The formaldehyde removal composite inoculant provided by the invention is prepared from a mixture of a compound fungus agent, earthworm dung and drug darkling beetle dung. After mixing of fungus agents with bio-enzyme, the obtained mixture is then mixed with earthworm dung and drug darkling beetle dung, thus obtaining the formaldehyde removal composite inoculant, which can be applied to removal of indoor formaldehyde. The formaldehyde removal composite inoculant is used for the microbial formaldehyde removal field.

Description

technical field [0001] The invention relates to a biological bacterial agent, in particular to a formaldehyde-removing composite bacterial agent and its application. Background technique [0002] Formaldehyde (HCHO) and volatile organic compounds (VOCs) are the main pollutants in indoor air. Especially formaldehyde, which contains a large amount of formaldehyde in interior decoration and home decoration materials, short-term exposure to formaldehyde can lead to abnormal sense of smell, skin and nasal mucosa allergies, abnormal lung function and other symptoms. Long-term exposure can cause various chronic respiratory diseases, such as asthma, nasopharyngeal cancer, leukemia, chromosomal abnormalities in newborns, central nervous system dysfunction, memory and mental decline, etc. At present, in order to remove indoor formaldehyde and volatile organic compounds (VOC), the common method is to carry out ventilation treatment, but due to the influence of outdoor weather and envi...
