Abstract

The invention discloses a method for preparing adsorbents through saccharomyces microorganism modified tea by-products. The method includes the following steps of crushing processing of the tea by-products, mixing of saccharomyces microorganism and binders, material mixing, culturing and modification and obtaining of adsorbents. The adsorbents are used for absorbing formaldehyde, benzene, methylbenzene and the like. In the culturing process, the saccharomyces microorganism grows, fermentation is conducted on cellulose, pectin, terpene and other matter in tea powder, reactions of oxidation, degradation, decomposition, splitting decomposition and the like are generated, accordingly modification is conducted on the surface chemical property and the pore structure of the tea by-products, and the chemical adsorptive property and physical adsorptive property of the adsorbents are synchronously improved beneficially. It is tested that the formaldehyde, the benzene and the methylbenzene are obviously lowered in the space where the adsorbents are placed, it is indicated that modification of the saccharomyces microorganism is conducted, and the adsorptive property of the tea by-products is improved.

Description

technical field [0001] The invention relates to the field of modification of tea by-products, in particular to a method for preparing an adsorbent by modifying tea by-products with microorganisms belonging to the genus Saccharomyces. Background technique [0002] Tea is a large agricultural and forestry by-product in my country and plays an irreplaceable and fundamental role in the national economy. With the development of the tea industry, there will be a large amount of processing by-products such as young tea leaves, tea stems and tea powder. If these tea by-products cannot be comprehensively utilized, it will cause great resource waste and economic loss. The recycling of tea by-products can not only help adjust the structure of the tea industry, extend the tea industry chain, but also increase the income of tea farmers, solve the "three rural issues", and improve the enthusiasm of tea farmers and enterprises in planting, processing, and management, which is in line with...
