Abstract

The invention discloses a method for treating uranium enrichment biomass through combination of phanerodontia chrysosporium and modified activated carbon and application thereof. The purpose is to solve the problem that currently, corresponding uranium enrichment biomass pre-treatment methods are scarce so that the requirements of uranium enrichment biomass treatment cannot be met. According to the method, thiobacillus ferrooxidans are used for degrading the uranium enrichment biomass lolium perenne, the phanerodontia chrysosporium is used for secondary degradation of residues, and finally, the activated carbon is used for conducting adsorption treatment on uranium generated by degradation to achieve enrichment treatment of the uranium in the uranium enrichment biomass. Furthermore, according to the method, through orthogonal experiment optimization, the material dosages in the technology are greatly reduced, and the cost and the energy consumption in the technology are reduced, whichis more beneficial to application and development of the industry of the method; the phenomenon that the method has a better degradation effect on lignin, hemicellulose and cellulose in the uranium enrichment biomass, higher adsorption efficiency on the uranium, and important significance to reduction and harmlessness treatment conducted on the uranium enrichment biomass is verified.

Description

technical field [0001] The invention relates to the field of environmental treatment, especially the field of heavy metal-enriched biomass disposal, and specifically relates to a method for treating uranium-enriched biomass in combination with white rot fungi and modified activated carbon and its application. The invention can realize the reduction and harmless treatment of uranium-enriched biomass, and has extremely high application value and application prospect. Background technique [0002] In recent years, with the continuous transfer of heavy metals such as uranium to the environment, the ecological environment has been seriously damaged. Among the current ecological environment restoration technologies, phytoremediation technology has become one of the most important research directions in environmental ecological restoration due to its advantages of environmental friendliness, low price and easy operation, and has attracted widespread attention (References: (1) Hao X...
