Description

technical field

[0001] The invention relates to the technical field of sewage biological treatment, in particular to a sulfur-iron autotrophic denitrification device and a reaction control method. Background technique

[0002] Sulfur-iron autotrophic denitrification technology is used in more and more applications in sewage treatment. The combination of the two can synergistically carry out deep denitrification of sewage. In the existing technology, the adequacy of the reaction needs to be verified and a reasonable ratio can be realized. At the same time, there is less involvement in the reaction control in the later stage of the reaction device that has been formed, and there is no precise control of the temperature and concentration changes in the reaction. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a sulfur-iron autotrophic denitrification device and a reaction control method for the deficiencies in the a...
