Wastewater discharge monitoring device

A waste water discharge monitoring device for monitoring waste water discharge by suctioning fluid outside at least one hollow stator blade including an inner space into the inner space through a slit formed in the surface of the stator blade in a steam turbine, the waste water discharge monitoring device being provided with: a gas-liquid separation device for separating gas from liquid in the stator blade; the fluid sucked into the internal space is separated into a liquid phase and a gas phase; a liquid phase flow rate measurement device for measuring the flow rate of the liquid phase separated by the gas-liquid separation device; a gas phase flow rate measurement device for measuring the flow rate of the gas phase separated by the gas-liquid separation device; a liquid-phase return line that connects the liquid-phase flow rate measurement device and the steam turbine; and a gas-phase return line that connects the gas-phase flow rate measurement device and the steam turbine. 一种废水排放监视装置，在蒸汽轮机中，用于对经由在包括内部空间的中
