CLEANING DEVICE FOR DISSOLVED OXYGEN MEASUREMENT SENSOR IN SEWAGE TREATMENT PLANT

摘要

The present invention relates to a cleaning device for a dissolved oxygen (DO) measurement sensor in a sewage treatment plant which can clean a measurement sensor which measures dissolved oxygen (DO) from sewage accommodated in a sewage treatment plant by remote control without separate personnel deployment. According to an embodiment of the present invention, the cleaning device for a dissolved oxygen measurement sensor in a sewage treatment plant comprises: a sensor unit (100) inserted into sewage (3) accommodated in an aeration tank (1) to measure dissolved oxygen (DO) of the sewage (3); a vertical moving unit (200) allowing the sensor unit (100) to be coupled thereto, and vertically moving the sensor unit (100) in a vertical direction to insert the sensor unit into the sewage (3) or remove the sensor unit (100) from the sewage (3); a cleaning unit (300) which is coupled to an inner wall of the aeration tank (1), allows the vertical moving unit (200) to penetrate the same in the vertical direction, and uses a brush (350) and ultraviolet light (UV) or low-temperature plasma to clean the sensor unit (100) vertically moved and inserted thereinto by the vertical moving unit (200); and a control unit (400) to control operations of the sensor unit (100), the vertical moving unit (200), and the cleaning unit (300).;COPYRIGHT KIPO 2020
