Ammonia-oxidizing bacteria immobilized glass plate and production method thereof

Abstract

The invention discloses an ammonia-oxidizing bacteria immobilized glass plate. A production method of the ammonia-oxidizing bacteria immobilized glass plate comprises the following steps: cleaning a glass plate, and modifying the cleaned glass plate with a mixed solution formed by potassium bitartrate, potassium tert-butoxide, agarose and potassium hydrogen phthalate in order to obtain a substanceA; modifying the substance A with a mixed solution formed by 2-chloro-3-cyanopyrazine, 2-bromo-5-nitropyridine and 4-bromotetrahydropyran in order to obtain a substance B; modifying the substance B with a mixed solution formed by tetrahydrothiopyran-4-one and 1-aminoanthraquinone in order to obtain a substance C; and immobilizing the ammonia-oxidizing bacteria on the substance C to obtain a substance which is the ammonia-oxidizing bacteria immobilized glass plate. The ammonia-oxidizing bacteria immobilized glass plate has the advantages of high strain activity, and efficient degradation of ammonia nitrogen in wastewater.

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 glass plate for immobilizing ammonia oxidizing 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. It uses physical or chemical methods to fix free microbial cells into particles through self-agglomeration or in a specific cushion material. It remains 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 concen...

AI Technical Summary

Problems solved by technology

Various sewage treatment plants generally use the traditional activated sludge method for biological denitrification in the treatment of domestic sewage and municipal sewage. Due to the rising cost of environmental treatment, immobilized microbial technology has been continuously researched and developed. It will be used in wastewater treatment and even water treatment. Playing an increasingly important role in pollution control, however, there is still a lack of materials for immobilizing ammonia oxidizing bacteria. Therefore, the development of materials for immobilizing ammonia oxidizing bacteria is of great significance for the treatment and restoration of nitrogen-polluted water bodies
