PURPOSE : An apparatus for processing village sewage using rare earth element-based balls is provided to secure sufficient solid retention time and reduce installation area by arranging a filtering part between an anoxic part and an aerobic part.CONSTITUTION : A reaction bath(200) successively processes village sewage by being divided into an anoxic part, an aerobic part(20), and a filtering part(30). The filtering part receives up-flow village sewage through the aerobic part. A guiding path(50) induces the village sewage through the aerobic part to the lower inlet of the filtering part. A contact processing media is filled in the aerobic part. The contact processing media is composed of rare earth element-based balls. A transferring path is formed between the anoxic part and the aerobic part to separate the anoxic part and the aerobic part.COPYRIGHT KIPO 2011
