The present invention relates to a sewage treatment facility for a cage-culture fish farm and a sewage treatment method using the same. According to the present invention, the sewage treatment facility for a cage-culture fish farm includes a flow-control and aeration tank and a separator membrane reactor tank, can be easily installed on a support plate extended to the outside of a cage frame by being supported by a support at one side of a container living area on the cage frame, can treat 1.0-2.5m3 of sewage per day, has total retention time of 55-75 hours, and has the maximum biological oxygen demand (BOD) and suspended solid (SS) of 5 ppm. As the present invention can be installed without any structural changes to the existing container living area by being customized to a cage-culture fish farm which has limited installation space, area, and weight and has a relatively-small amount of sewage since a small number of people live, it is possible to effectively purify living sewage from the cage-culture fish farm which has been discharged without treatment and discharge the purified water to the lake or coast so that eco-friendly fish farming is possible, damage to the surroundings can be minimized, and impact of pollution to cultured fish can be prevented. |
