Problems solved by technology

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

Abstract

The invention discloses a modified zeolite supporter used for immobilizing monocrotophos degrading bacteria, which is prepared through the following steps: washing zeolites, and modifying the zeolites with a mixture solution prepared from dibromobenzoquinone, ethyl acrylate, oxyacetylchloride, isopropyl alcohol and dimethylamino sulfonyl chloride to obtain a substance B; modifying the substance B with a mixture solution prepared from phenyl dichlorosilane, ethanol, 5-methylisatin, polycytidylic acid, methylol urea and dimethylamino sulfonyl chloroalkane to obtain a material, which is the modified zeolite supporter used for immobilizing the monocrotophos degrading bacteria.

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 in particular relates to a modified zeolite carrier for immobilizing monocrotophos-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 strai...
