The invention relates to an
odor treatment system for an indoor polluted space. The
odor treatment system comprises: a
microorganism carrier, which is arranged in the indoor polluted space; an activemicroorganism storage device, which is used for storing an active
microorganism bacterium solution; an atomization device, which is used for spraying the active
microorganism bacterium solution to themicroorganism carrier; a
gas pipeline, which is arranged in the indoor polluted space; high-energy
ion equipment, which is used for introducing
ion fresh air into the
gas pipeline; a photocatalytic deodorization lamp, which is arranged in the
gas pipeline and used for carrying out photocatalytic deodorization; an
odor detection device, which is used for detecting the concentration of odor in theindoor polluted space; a
humidity sensor, which is used for detecting the
humidity of the microorganism carrier; and a control device, which is used for controlling the atomization device to spray theactive microorganism bacterium solution to the microorganism carrier according to the
humidity of the microorganism carrier, and controlling the high-energy
ion equipment and the photocatalytic deodorization lamp according to the concentration of the odor for photocatalytic deodorization under ion
fresh air. The odor
treatment system provided by the invention realizes deodorization of a pollutedspace which is not prone to collection and concentrated treatment of odor and is low in concentration.
