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 polycarbonate-based modified Functional materials used to immobilize phorate-degrading bacteria, which is of great significance for the treatment and restoration of phorate-contaminated environments

Abstract

The invention discloses a functional material for fixing phorate degrading bacteria based on polycarbonate modification. Polycarbonate is cleaned and is then prepared into a substance B through being modified by a mixed solution prepared from 2,5-furandicarboxylic acid, ethyl alcohol, 3-chloro-4-methylpyridazine, 2-hydroxyanthraquinone, 3-flavonol and N-2-naphthyl-3-hydroxyl-2-naphthanilide; the substance B is modified by a mixed solution prepared from acetone phenylhydrazone, ethyl alcohol, quinoline-8-carboxaldehyde, 4-benzopyrone-2-carboxylic acid and 4-chloro-3-nitropyridine; and an obtained substance is the functional material for fixing the phorate degrading bacteria based on polycarbonate modification.

Description

technical field [0001] The invention belongs to the field of research and development and preparation of functional materials of environmental pollution control technology, and particularly relates to a polycarbonate-based functional material for immobilizing phorate-degrading bacteria. 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 strains, high microbial densit...
