A raw water purifying apparatus utilizing anaerobic microorganisms comprises a casing (1) and a carrier assembly (2). The casing (1) is a vertical type and comprises a body (3), a bottom wall (4) and a ceiling (5). At the upper portion of the casing an inflow port (6) of raw water is open and at the lower portion an outflow port (7) locates. The carrier assembly (2) is formed, by piling plural carrier discs (8) of porous polyethylene for rooting anaerobic microorganisms inclusively therein with each space (9) between every two carrier discs (8), so as not to overlap liquid passages (10) which are provided evenly all over each disc (8) through thereof with each other. The carrier assembly (2) is so settled in said casing (1) as to prevent the direct leading of said inflow port (6) to said outflow port (7). Raw water may be treated at one time or repeatedly. <IMAGE> |
