Upper-layer waste liquid demulsification separation collector and upper-layer waste liquid demulsification separation method

The invention discloses an upper-layer waste liquid demulsification separation collector and an upper-layer waste liquid demulsification separation method, and belongs to the technical field of liquid separation. An upper-layer waste liquid demulsification separation collector comprises a separation bottle, the bottom and the top of the separation bottle are respectively provided with a liquid inlet and an overflow port which are used for adding filling liquid into the separation bottle, and the side wall of the separation bottle is provided with a feeding port which is used for adding emulsion into the separation bottle filled with the filling liquid; the bottom end of the collecting pipe extends into the bottom of the inner side of the separation bottle, and the collecting pipe is used for collecting the demulsified wastewater. The separation bottle is used for demulsifying and separating the two-phase emulsion in which the density of the dangerous waste liquid is greater than that of the other phase, and t
