PURPOSE: A simultaneous treatment system of hydrogen sulfide and ammonia using attached biofilm is provided, which can remove hydrogen sulfide and ammonia generated from excrement treatment, livestock farming, sewage treatment, waste landfill and chemical plant simultaneously. And the system can diminish the treatment cost by more than 40 % and does not emit any secondary pollutant. CONSTITUTION: The system comprises the followings: (i) a first biofilm bubble column reactor (6) in which attached biofilm is contained for removing hydrogen sulfide and ammonia simultaneously; (ii) a second biofilm bubble column reactor (8) in which attached biofilm is contained; and (iii) a mass flow controller (26) for controlling concentration and flow of hydrogen sulfide and ammonia. The hydrogen sulfide is removed by attached biofilm, and ammonium sulfate produced by reaction of ammonia with hydrogen sulfide is removed by microorganism at the bottom of the reactor.
