An aeration type underwater screen system capable of decomposing waste material into fine particles by a fine mesh screen (2) installed vertically with a slope and a swing flow without allowing the fine mesh screen (2) to be clogged by air bubbles produced from a diffusion tube (6), comprising the fine mesh screen (2) installed on a screen mounting means (3) for mounting the fine mesh screen (2) so as to divide a solid-liquid separation tank (1) into a sewage flow-in side (1a) and a filtrated liquid drain side (1b) through the fine mesh screen (2) provided in the solid-liquid separation tank (1) and so that the upper side thereof is fallen down, the diffusion tube (6), a sewage flow-in means (7), a filtrated liquid drain means (8), and a sediment drain means (9) for draining sediment installed on the underside of the sewage flow-in side (1a).
