Claims

[Scope of utility model registration request]

A compaction concentration section and a sludge discharge pipe communicating with this section are installed at the bottom of the tank, and a mixing and coagulating chamber for the liquid to be treated and a channel for separating the liquid are installed at the top half of the tank. In a sedimentation device that is equipped with a collecting section for separated supernatant water separated through a separation flow path and a supernatant water discharge pipe communicating with the collecting section, the lower bottom part following both side walls of the water tank is shaped like an arc, and the condensation concentration is carried out. At the same time, a rotary shaft is pivotally supported in the center of the water tank directly below the solid-liquid separation flow path, and an arm rod that reaches the arc-shaped lower bottom of the water tank is attached to this rotary shaft. An appropriate number of arm rods are fixed, and a member for scraping off deposits is fixed on the tips of these arm rods, and the rotating shaft is rotated back and forth within a predetermined range via an appropriate interlocking mechanism to scrape off deposits. 1. A sedimentation device characterized in that a member is slid along an arcuate lower bottom portion of a water tank to scrape off sediment adhering to the lower bottom portion extending to both side walls of the water tank.
