preparation example Construction

[0024] The preparation method of biological fluid is:

[0025] (1) According to the mass ratio of 1:4-7, take lignite and waste oil for grinding, filter, and put the filter residue in a cultivation room with an air humidity of 50-70% and a temperature of 30-40°C for 10-15 day, collect the standing filter residue;

[0026] (2) In parts by weight, take 100-200 parts of water, 30-35 parts of standing filter residue, 12-18 parts of peptone, 10-14 parts of yeast extract, 4-7 parts of sodium chloride, 3-6 parts Sodium dihydrogen phosphate, 2-5 parts of disodium hydrogen phosphate and 1-3 parts of formaldehyde solution are put into a container, stirred and mixed, and cultured at 30-40°C for 25-32 hours;

[0027] (3) During the cultivation process, the boiler gas after dedusting is passed through the pipeline at a speed of 0.2-0.6m / s. The diameter of the pipeline is one-sixth of the diameter of the container. After the cultivation, the cultivation mixture is filtered , and collect t...

Abstract

The invention belongs to the technical field of environment protection and in particular relates to indoor air purification particles and a preparation method thereof. According to the indoor air purification particles, lignite is used as a bacterium source generating body and are mixed with hogwash oil; the hogwash oil provides a bacterium source and the surface of the lignite is decomposed through microorganisms so that the decomposition capability of the microorganisms on a carbon-containing compound is enhanced; in a culture optimization process, formaldehyde is added, so that the microorganisms can take the formaldehyde as a nutrient substance and the formaldehyde is utilized and decomposed, so that the purification efficiency on indoor air is enhanced; when an adhesive is selected, degradable materials including polyethylene glycol, polyglutamic acid and waterborne polyurethane are used, and nutrients are provided for the covered microorganisms through degrading the polyglutamicacid, so that the service life and time of a purification material are prolonged.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to indoor air purification particles and a preparation method thereof. Background technique [0002] With the rapid development of industry and economy, environmental pollution has become a social issue of common concern to mankind. As one of the main types of environmental pollution, air pollution caused by automobile exhaust, industrial smoke, and odorous gases in the living environment has attracted the attention of the scientific community. Many scientists are devoted to the research of waste gas treatment. Air purification materials are materials that absorb and decompose harmful substances in the air through physical and chemical methods. The application of air purification materials is an effective way to control air pollution sources. [0003] At present, indoor air purification materials and technologies mainly include the following categories:...
