Abstract

The invention belongs to the technical field of biological wastewater treatment, and specifically discloses a method for strengthening the film-forming ability of aerobic denitrifying bacteria. A method for strengthening the film-forming ability of aerobic denitrifying bacteria, comprising: step 1, preparing HM medium and LB medium; step 2, adding a ZnO NPs solution with a concentration of 1.0-1.5mM to the HM medium in step 1 ; Step 3, put the aerobic denitrifying bacteria strain into the HM medium in step 2 for cultivation; Step 4, select and complete the HM medium in step 3, and add it to the LB medium for rejuvenation; Step 5, will complete The aerobic denitrifying bacteria strain after step 4 is added to the HM medium in step 1 for continuous culture. The purpose of the present invention is to provide a method for strengthening the film-forming ability of aerobic denitrifying bacteria, so as to solve the problems of weak film-forming ability of aerobic denitrifying bacteria and poor anti-ZnO NPs effect.

Description

technical field [0001] The invention belongs to the technical field of biological wastewater treatment, and specifically discloses a method for strengthening the film-forming ability of aerobic denitrifying bacteria. Background technique [0002] At present, with the rapid development of the national economy and the continuous deepening of the urbanization process, the total discharge of urban domestic and industrial wastewater is also increasing year by year. The widespread use of pesticides, chemical fertilizers, and synthetic detergents has led to a continuous increase in the concentration of nutrients in water bodies, among which nitrogen is one of the main causes of eutrophication in water bodies. The conventional denitrification process generally separates the nitrification process and the denitrification process in two reaction units, because most denitrifying bacteria require anaerobic conditions, while nitrifying bacteria require an aerobic environment. The discove...
