Claims

[Scope of utility model registration request]

A ring-shaped coagulation tank capable of ensuring sufficient residence time of raw water from the raw water introduction pipe, which has a plurality of compartments arranged in parallel with the raw water introduction pipe via a partition plate, and this coagulation tank can be freely attached or removed. A gravity separator comprising a separation chamber having an opening provided therein and a container body having a large gravity separation chamber, wherein the coagulation is carried out in order to supply raw water directly into the large gravity separation chamber of the gravity separator. a raw water inflow pipe connected to the tank in a hanging manner, a first separator located in the large gravity separation chamber supported in an expanded manner at the lower end opening of the raw water inflow pipe; A second separator is installed above the separator at an appropriate interval and is supported in an expanded shape and is equipped with a through hole that controls sedimentation and allows clear water to pass through. A third separator is installed at an appropriate interval above and is equipped with a through hole that controls sedimentation separation and allows clear water to pass through, and the clear water that has been sedimented and separated in the first to third separators is discharged. a clear water discharge pipe connected to the clear water discharge pipe and extending outside the gravity separation chamber, and a clear water discharge pipe located above the gravity separation chamber and above the inner bottom surface of the flocculation tank. A floating sludge discharge pipe, a sludge discharge port provided at the bottom of the gravity separation chamber of the container body, a sludge discharge pipe communicating with the sludge discharge port, and a rotatable scraper plate are provided directly below raw water such as sludge water. type solid-liquid gravity separation device.
