Abstract

The invention belongs to the technical field of environmental remediation, and particularly relates to a composition for degrading pollutants, a preparation method of the composition and application of the composition in degrading soil pollutants. The invention provides a composition for degrading pollutants. The composition is prepared from electrically activated photosynthetic bacteria and modified biochar, the electrically activated photosynthetic bacteria are photosynthetic bacteria subjected to potential domestication under the condition of containing pollutants; the modified biochar is prepared by taking a phenazine compound and biomass as raw materials through a hydrothermal method and drying treatment. The invention provides a composition for degrading pollutants as well as a preparation method and application of the composition, which can effectively solve the technical problems of poor adaptability, low efficiency, secondary pollution, high environmental risk and high cost in the existing in-situ remediation of polluted soil.

Description

technical field [0001] The application belongs to the technical field of environmental remediation, and in particular relates to a composition for degrading pollutants, a preparation method thereof and an application in degrading soil pollutants. Background technique [0002] The rapid development of human society and economy has led to the rapid deterioration of the environment, especially the chemical industry is a heavy polluting industry, and there are many highly toxic chemical industrial products, resulting in organic-heavy metal compound pollution in the site left by the company's relocation and the surrounding soil, which seriously endangers ecological security and the human body. healthy. [0003] Currently, the technologies used for in-situ remediation of organic-heavy metal complex pollution mainly include: [0004] (1) Physicochemical method: adding chemical agents to oxidize and degrade organic pollutants, extracting soil volatile organic pollutants through the...
