pH SENSOR UNIT FOR MEASURING pH OF MINE DRAINAGE AND MINE DRAINAGE TREATMENT SYSTEM USING THE SAME

摘要

The present invention relates to a pH sensor unit for measuring mine drainage. The present invention measures the pH by sampling a small amount of mine drainage from the mine drainage treatment facility, and washing the electrode of the pH sensor with a strong acid solution to prevent scale adhesion. The entire process from sampling of mine drainage to pH measurement and cleaning of the sensor is automatically controlled by the controller, and is performed for a very short time of about 1 minute.
