In addition to providing a collecting body for collecting contaminants mixed in the waste water flowing into the separating tank main body from the first inlet in the separating tank main body, a sealing body connected to the first outlet is provided,
The second inflow port and the second outflow port are communicated with each other by a communication portion penetrating the inside of the separation rod main body, and the interior communicating with the first inflow port and the first outflow port of the separation rod main body is Separation device characterized by being isolated. It has a bottomed cylindrical separation rod body with a cleaning opening that is covered with a lid that can be opened and closed at the top.
An inlet and an outlet communicating with the inlet are formed on the side of the separation rod main body,
The inflow port and the outflow port communicate with each other in the separation rod body,
In addition to providing a separating body that collects contaminants mixed in the waste water flowing into the separating body from the inflow port, a sealing body connected to the outflow port is provided in the separating body.
A separating dredge apparatus, characterized in that a space portion for disposing a drainage main pipe is formed in a side portion of the separating dredge main body located below the cleaning port of the separating dripping main body. The position of the lower end portion of the outlet formed in the separation rod body is lower than the position of the lower end portion of the inlet,
The collector has an upper surface and an inflow hole communicating with the inner end side of the inlet of the separation rod main body at the upper portion of the peripheral side surface and a liquid collecting portion for collecting impurities at the lower portion.
With the inflow hole of the collector in communication with the inner end side of the inlet of the separating rod main body, the upper surface opening edge of the collector is above the position of the lower end of the inlet formed in the separating rod main body. And a position of an upper end portion of a liquid collecting portion for collecting contaminants formed in the collector is lower than a position of a lower end portion of an outlet formed in the separation rod main body. Item 3. A separating dredge apparatus according to item 2.
