Abstract
The present disclosure discloses to a method for determining optimum preservation temperature of a sulfur autotrophic denitrifying bacteria biofilm, and belongs to the technical field of environment engineering. The method of the present disclosure comprises: determining the cell activity state of a sulfur autotrophic denitrifying bacteria biofilm preserved at different temperatures by flow cytometry, and determining the preservation temperature of the cell activity state closest to the cell activity state of the sulfur autotrophic denitrifying bacteria in pilot operation as the optimum preservation temperature. The cell activity state and performance effect are verified to be reliable after activity recovery by the test data. The method of the present disclosure can simplify the microbial activity recovery process of the sulfur autotrophic denitrifying bacteria biofilm, quickly start the sulfur autotrophic denitrifying bacteria biofilm sewage treatment, enable the removal rate of nitrate nitrogen and total nitrogen in a sewage treatment plant to reach 96% and 88% or above respectively, achieve the effects of energy saving and consumption reduction at the same time, and have very high industrial feasibility.
