Embodiment 1

[0009] Mix 15% of bark powder, 5% of sawdust, 40% of calcium carbonate, and 1% of bamboo charcoal powder, then add 29% of adhesive and mix well, and bake the filler at 100°C for 15 minutes. The adhesive is made of ethylene / vinyl acetate and Na 2 O nSiO 2 A mixture composed in a weight ratio of 2:1.

Embodiment 2

[0011] Bark powder 20%, sawdust 10%, calcium carbonate 50%, bamboo charcoal powder 3%, adhesive 17%. The adhesive is made of ethylene / vinyl acetate and Na 2 O nSiO 2 A mixture composed in a weight ratio of 2:1.

Embodiment 3

[0013] Bark powder 25%, sawdust 15%, calcium carbonate 45%, bamboo charcoal powder 5%, adhesive 10%. The adhesive is made of ethylene / vinyl acetate and Na 2 O nSiO 2 A mixture composed in a weight ratio of 2:1.

Abstract

The invention provides deodorization composite biological stuffing. The deodorization composite biological stuffing comprises the following components in percentage by weight: 15%-25% of bark powder, 5%-15% of saw dust, 40%-50% of calcium carbonate, 1%-5% of bamboo charcoal powder and 10%-40% of a bonding agent, wherein the bonding agent is a mixture of ethylene / vinyl acetate and Na2O.nSiO2. The stuffing has high intensity, can keep favorable bonding strength in a damp environment for a long time, and plays a role of fixing and releasing nutritional substances; the nutritional ingredients are released slowly by virtue of a dissolving diffusion and microorganism decomposition synergistic effect and are difficult to leach at the state with water, thus the stuffing is superior to traditional organic stuffing.

Description

technical field [0001] The invention relates to deodorization technology, in particular to a deodorization composite biological filler. Background technique [0002] All substances that stimulate the smell of olfactory organs are called odor pollutants, among which hydrogen sulfide, ammonia, methane, mercaptans and phenols are more harmful to humans. In addition to causing unpleasant feelings such as psychological disgust, foul-smelling pollutants can also cause symptoms such as nausea, headache, and loss of appetite. Biological filtration method is a relatively new air pollution control method, which uses microorganisms to degrade or transform volatile organic compounds, hydrogen sulfide, and ammonia. It has high treatment efficiency, low infrastructure and operating costs, no need to add chemical reagents, and no secondary pollution. and other advantages, but the growth of microorganisms requires the use of fillers as biological media. The existing fillers have different ...
