The present invention relates to a system for deodorizing and removing color and turbidity from sewage, wherein the instantaneous suction amount of polluted air is increased by using a high output ring blower so as to increase sterilization efficiency and distribute ozone to be discharge to the outside a great distance, and the reflection amount of UV light is increased so as to improve sterilization force and an ozone generation amount. In addition, the sterilization of water and air can be selectively achieved as an additional function. To this end, in a system for deodorizing and removing color and turbidity from sewage, provided and used in a water treatment facility such as a stable, a hospital, a septic tank, a sewage disposal plant, a waste water disposal facility, a heavy water processing facility, and a rain water treatment facility, which require sterilization, sewage odor removal, disease prevention, heavy metal decomposition color removal, and turbidity removal, a system for deodorizing and removing color and turbidity from sewage is disclosed, comprising: a case to be provided to the water treatment facility a low pressure mercury lamp to be provided on the inside of the case a high output ring blower arranged at the case and sucking polluted air from the inside of the case, and discharging sterilized air and generated ozone from the case so as to distribute the same and a stabilizer provided on the inside of the case and electrically connected to the low pressure mercury lamp, and stabilizing power to be supplied to the low pressure mercury lamp.La présente invention concerne un système pour désodoriser et éliminer la couleur et la turbidité des eaux usées, la quantité daspiration instantanée dair pollué étant accrue par utilisation dun ventilateur à anneaux à débit élevé de façon à accroître lefficacité de stérilisation et à distribuer de lozone à décharger à lextérieur à une grande distance, et la quantité de réflexion de la lumière ultraviolette éta
