A disposal system for initial rainwater and sewer overflows using inclined plate sedimentation is provided to dispose of solids effectively and to make installation and maintenance easy by separating and removing oil and floating matters contained in overflows using a baffle drum, gloss solids using a screen and minute solids using an inclined plate unit. A disposal system(100) for initial rainwater and sewer overflows using inclined plate sedimentation comprises: an external wall(110) formed in a concrete structure or an FRP, PE or steel structure closed inward to prevent an inflow of external impurities in the ground and connected with a sewer by an inflow pipe(103) and an outflow pipe(104); a baffle drum(120) located in a space formed by the external wall and provided with an inlet(121) connected with the inflow pipe to make sewer overflows flow inward and to prevent the outflow of oil or floating matters(102) contained in the overflows; a screen(130) formed in the same cylindrical shape as the baffle drum to connect with the baffle drum stably as a lattice structure; an inclined plate unit(140) installed slantingly to cover up the cylindrical screen and composed of inclined plates(141) overlapped in many layers to make small floating matters, that is, minute solids(106) settled by gravity and moved into a sediment bucket of a lower sedimentation tank and many inclined plate spacers located between inclined plates to prevent the change of settling distance caused by transformation of the inclined plate; and a sedimentation tank(150) located on the lower part of the screen and the inclined plate unit to settle gloss solids(105) and minute solids too the bottom; and a sediment bucket(160) located to hang on a hanging projection(113) formed on an external wall(151) of the sedimentation tank and installed to be detachable to remove the solids settled in the sediment bucket from the outside. |
