Nitrous oxide (N2O) -suppressed sewage treatment technology using carbon fiber filled aerobic bioreactor

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for sewage treatment which suppresses emission of dinitrogen monoxide (NO) from sewage.SOLUTION: A sewage treatment method includes a step of subjecting sewage to an aeration treatment in the presence of fixed-bed type carbon fibers and suppresses generation of dinitrogen monoxide by utilizing microorganisms accumulated on the carbon fibers.
