摘要： A method and equipment are disclosed for tertiary sewage treatment by naturally-occurring microorganisms after the sewage has passed from a septic tank or other primary treatment device. Tertiary treatment occurs within enclosed, controlled conditions in a recirculation tank housing a recirculating spray system and a filter bed. The recirculation process is controlled by a timer and a timer float responding to the wastewater level in the recirculation tank. A mixing zone is provided in a bottom portion of the recirculation tank.
