The pH value of the ore pulp and the pH value of the water quality after water treatment are reflected by the detection data of the pH electrode.
The pH electrode is always in the detection pulp or detection solution, and the detection data is inaccurate and more serious is caused to be "poisoned" because the various detection liquids contain 'ions' (such as Ca2+, S2-, H+ and Na+) which have influence on the detection data, and the electrode is in the solution containing the harmful 'ions' for a long time.
Only the detection electrode is cleaned and maintained regularly, the accuracy of detection data can be ensured, and the service life of the electrode can be prolonged.
In a production field, the pH electrode is usually manually cleaned, and the detection electrode can not reflect the actual pH value of the detection liquid due to the problems of uncertain cleaning and the like in the manual cleaning, so that the pH value regulator added in the water quality treatment process can not be added according to the actual situation.
Due to inaccurate detection data, too much or too little slurry pH regulator is often added, and finally the slurry pH regulator is wasted or the slurry pH value cannot reach the actual set value.
