Abstract: Various embodiments of the present invention relate to a method for accurately detecting, by an electronic device, that a tray for loading a SIM card is detached. An electronic device according to various embodiments of the present invention may comprise: a tray for loading a SIM card; a first processor electrically connected to the tray; and a second processor electrically connected to the first processor, wherein the first processor is configured to transfer a pre-event to the second processor when a detachment event for the tray is detected, and the second processor is configured to identify, in each designated period, whether the SIM card is erroneous; and delay identification of whether the SIM card is erroneous, in response to reception of the pre-event. The present invention may further include various other embodiments.

Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).
