A harmful gas treatment apparatus is provided to treat harmful gas that has not been treated by bio filtering equipment only, and supply ozone generated from plasma treatment equipment to bio filtering equipment, thereby increase efficiency of the bio filtering equipment. A harmful gas treatment apparatus comprises: bio filtering equipment(10) filtering harmful gas supplied; plasma treatment equipment(20) decomposing the harmful gas that has been filtered in the bio filtering equipment; and a bypass pipe(30) supplying to the bio filtering equipment a portion of exhaust gas exhausted from the plasma treatment equipment after decomposing the harmful gas in the plasma treatment equipment. The bypass pipe has a gas amount-adjusting valve(31) installed thereon. The gas amount-adjusting valve includes a sensor(32) measuring the ozone concentration of a gas mixture of the harmful gas and exhaust gas, and a control part(40) controlling the sensor. The bio filtering equipment includes a water tank(17), a bio filtering part, a harmful gas inlet, a water spray, and an outlet(19). The harmful gas treatment apparatus further comprises a neutralizer feeder(14), a nutrient feeder(15), and an air bubble feeder(16).
