Embodiment 1

[0038] Its preparation method comprises the following steps:

[0039] (1) Dry and pulverize walnut shells, corn cobs, peony seed shells, and tea seed shells to obtain mixture A; pulverize maidenhair fern and Tianqing leaves to obtain mixture B;

[0040] (2) Take the pulverized mixture A, add sodium carboxymethylcellulose and water, and mix well;

[0041] Mixture A: water: sodium carboxymethylcellulose = 1:0.3-0.8:0.001-0.002, then add Bacillus subtilis, ferment at 35-38°C for 48-72h, record as fermentation product A;

[0042] Bacillus subtilis agent: mixture A=0.001:1, Bacillus subtilis is 1×10 8 -10 9 cfu / g;

[0043] Take the pulverized mixture B, add starch and water, and mix well;

[0044] Mixture B: starch: water = 1:0.02-0.06:0.5-0.8, then add Trichoderma harzianum, ferment at 35-38°C for 36-64h, and record it as fermentation product B;

[0045] Trichoderma harzianum inoculant: mixture B=0.002:1, Trichoderma harzianum is 2×10 8 -10 9 cfu / g;

[0046] The parts by w...

Embodiment 2

[0067] Different from the weight ratio of raw materials in Example 1, the method is the same as in Example 1.

[0068] The ratio of raw materials is:

[0069] Steelmaking slag 70-100 Activated carbon 15-30

[0070] Walnut shell 5-15 brown silk 10-20

[0071] Peony seed shell 10-30 corn cob 20-30

[0072] Tea seed shell 10-20 Bottom mud 20-30

[0073] Kaolin 25-35 Shale 15-25

[0074] Adiantum 3-10 Tian Qingye 5-15.

[0075] The specific parameters are as follows:

[0076] Mixture A: water: sodium carboxymethylcellulose = 1:0.3:0.001, then add Bacillus subtilis, and ferment at 35°C for 48 hours;

[0077] Mixture B: starch: water = 1:0.02:0.5, then add Trichoderma harzianum, and ferment at 35°C for 36 h.

[0078] In the granulation step, the structure of the granulated particles is as follows: there is a cylindrical channel 2 in the center of the granule, and the channel 2 is used as the dividing line. There are multiple cavities 3 on both sides of the channel. These cavi...

Embodiment 3

[0080] Different from the weight ratio of raw materials in Example 1, the method is the same as in Example 1.

[0081] The ratio of raw materials is:

[0082] Steelmaking Slag 100 Activated Carbon 30

[0083] Walnut shell 15 brown silk 20

[0084] Peony seed shell 30 Corn cob 30

[0085] Tea seed shell 20 bottom mud 30

[0086] Kaolin 35 Shale 25

[0087] Adiantum 10 Tian Qing Ye 15 .

[0088] Mixture A: water: sodium carboxymethylcellulose = 1:0.8:0.002, then add Bacillus subtilis, and ferment at 38°C for 72 hours;

[0089] Mixture B: starch: water = 1:0.06:0.8, then add Trichoderma harzianum, and ferment at 38°C for 36 h.

Abstract

The invention belongs to the field of environment protection, in particular relates to an air purification adsorbent and also relates to a preparation method of the air purification adsorbent. The air purification adsorbent is characterized in that the adsorbent is prepared from the following raw materials: steel-making furnace slag, active carbon, walnut shell, palm fiber, peony seed husk, corncob, tea seed husk, bottom mud, kaolin, shale, adiantum capillus-veneris and leaf of sesbania. The air purification adsorbent has the beneficial effects that the method provided by the invention is adopted and the materials have a better adsorption performance through a fermentation treatment manner, and organic pollutants or dust or haze in the air can be more comprehensively absorbed, so that the air purification aim is realized; the structure of the adsorbent provided by the invention is different from that of common adsorbent granules; the structure is improved so that the air purification adsorbent can more easily absorb various harmful substances.

Description

technical field [0001] The invention belongs to the field of environmental protection, and specifically relates to an air-purifying adsorbent, and also relates to a preparation method of the above-mentioned adsorbent. Background technique [0002] With the enhancement of people's awareness of environmental protection, more and more attention is paid to the improvement of the environment, especially the air quality. Indoor air pollution mainly comes from the following aspects: decoration pollution and air pollution. [0003] In the decoration process, commonly used decoration materials, such as paint, coatings, floor leather, wallpaper, plywood, plastics, polyvinyl chloride (PVC) boards, insulation materials, and interior artificial boards, such as large core boards and other glued panels , MDF furniture and art works, etc., will release volatile organic compounds. At present, 350 species have been identified, mainly aromatic hydrocarbons and aliphatic hydrocarbons. The ...
