Problems solved by technology

Immobilizing phorate-degrading bacteria is one of the most effective means to restore phorate-polluted environment. However, there is still a lack of functional materials for immobilizing phorate-degrading bacteria. Therefore, the development of immobilized phorate-degrading bacteria Modified activated carbon carrier, which is of great significance for the treatment and restoration of phorate polluted environment

Abstract

The invention discloses a modified activated carbon carrier for immobilizing a phorate degradation bacterium. Activated carbon is washed and modified with a mixed liquid prepared from 3-chloro-6-phenyl pyridazine, alcohol, 4-(2-aminoethyl)-tetrahydropyrane, 2-bromo-5-cyanopyrazine and 5-chloro-3-methylbenzothiophene to prepare a substance B; the substance B is modified with a mixed liquid prepared from ZrCl4, CeCl3, Cu(NO3)2 and Sr(NO3)2 to prepare a substance C; and the substance C is modified with a mixed liquid prepared from 3-hydroxyflavone, alcohol, chlorphenyl silane and 2-imidazolidone to obtain a substance which is the modified activated carbon carrier for immobilizing the phorate degradation bacterium.

Description

technical field [0001] The invention belongs to the field of research and development and preparation of functional materials for environmental pollution control technology, and in particular relates to a modified activated carbon carrier for immobilizing phorate-degrading bacteria and a preparation method thereof. Background technique [0002] Immobilized microorganism technology is a biotechnology developed from immobilized enzyme technology in biochemical industry in the 1960s. By chemical or physical means, free cells are positioned in a limited space area to keep them active and can be used repeatedly. In the late 1970s, with the increasingly serious water pollution, this technology was applied to the biological treatment of industrial wastewater due to its unique advantages. Compared with the traditional suspension biological treatment method, immobilized microorganism technology has the ability to improve the microbial Cell concentration, maintaining high-efficiency s...
