Abstract

The invention discloses hydrophobic VOC adsorption and degradation biological filler as well as a preparation method and application thereof, and relates to the technical field of environmental governance. The hydrophobic VOC adsorption and degradation biological filler comprises the following components in parts by weight: 50-70 parts of adsorption resin, 5-10 parts of attapulgite, 5-15 parts of glucose, 2-5 parts of limestone and 15-20 parts of an adhesive. The hydrophobic VOC adsorption and degradation biological filler disclosed by the invention comprises the adsorption resin, and the adsorption resin is preferably a porous cross-linked polymer and does not have an ion exchange functional group, so that the biological filler has a rich porous structure and a high specific surface area, can adsorb organic matters under the action of a hydrophobic interface, and has a good removal effect on hydrophobic VOC; besides, the biological filler also contains glucose, attapulgite and limestone, can provide a carbon source and trace elements for loaded microbial strains, and can adjust pH, eliminate acidic substances generated by metabolism of the strains and maintain pH conditions suitable for growth of the strains.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and in particular relates to a hydrophobic VOC adsorption-degradation biofiller and a preparation method and application thereof. Background technique [0002] VOC (volatile organic compounds) refers to a class of active volatile organic compounds, that is, volatile organic compounds that are harmful and have a huge impact on human health. [0003] At present, commonly used VOC treatment methods can be divided into three categories: physical method, chemical method and biological method. Compared with physical and chemical methods such as adsorption or catalytic oxidation, the biological method has the advantages of simple process, mild operating conditions (normal temperature, normal pressure), good treatment effect, no secondary pollution and less energy consumption. The best way to VOC exhaust. [0004] Bioreactor refers to a reaction system that uses naturally occurring micr...
