Biological deodorization filler with physical, chemical and biological synergistic effect

Abstract

The invention discloses a biological deodorization filler with a physical, chemical and biological synergistic effect. The biological deodorization filler is prepared from the following raw materials in percentage by weight: 15 to 20 percent of a shell material which achieves a neutralizing effect to adjust the pH of a system, 70 to 85 percent of a volcanic rock material for providing a microorganism growing environment and adsorbing pollutants and 1 to 15 percent of a pyrite slag material for enhancing the capacity of removing reducing pollutants. A filling mode of the biological deodorization filler is as follows: a mixture of the volcanic rock material and the pyrite slag material is used as an upper-layer filler, and the shell material is used as a lower-layer filler; a gap which is 10 to 20 mm in height is reserved between the two layers of fillers. The component materials of the biological deodorization filler are wide in source, and the biological deodorization filler has an adsorption effect on all types of pollutants in gas, is long in service life, favorable for biological growth and high in system buffer capacity and stability, enhances the removal effect on the reducing pollutants such as hydrogen sulfide and realizes regeneration of components achieving an oxidization effect.

Description

technical field [0001] The invention relates to the field of odor control, in particular to a biological deodorizing filler suitable for odor control and possessing physical, chemical and biological synergistic effects. Background technique [0002] Odor pollutants have varying degrees of damage to the human respiratory system, circulatory system, digestive system, endocrine system, and nervous system, and can cause death in severe cases. Odor pollutants have a wide range of sources, mainly including: municipal sanitation and factory pollution sources; there are many types, mainly including: sulfur-containing compounds (such as hydrogen sulfide and methyl mercaptan, etc.), nitrogen-containing compounds (such as ammonia and amines, etc.) ), benzene, hydrocarbons, etc. In view of the harmfulness of odorous pollutants, for different sources and types of odorous substances, the "Emission Standards for Odor Pollutants" (GB14554-1993) and "Emission Standards for Pollutants in Pet...

AI Technical Summary

Problems solved by technology

[0005] Organic fillers such as sawdust, tree roots, and bark are perishable, and the filler layer will harden and collapse, resulting in increased pressure loss and increased energy consumption in the biological deodorization equipment

In addition, rotting organic fill can give off a foul smell and add to pollution

Inorganic fillers such as ceramics have poor bioattachment and growth

[0006] During the biological deodorization process, the biological metabolism produces sulfuric acid, nitric acid and organic acids. If the pH is not adjusted in time, the biological deodorization system will be acidified, which will affect the growth and metabolism of the organisms and reduce the efficiency of the biological deodorization system.
