.AUTO-CONTROL SYSTEM AND METHOD OF FENTON OXIDATION FOR PRETREATING CHEMICAL WASTEWATER

摘要

The present invention relates to a pantone oxidation automatic control device and method for chemical wastewater pretreatment. The present invention periodically calculates the redox potential measuring devices 102 and 104 for measuring the potential difference in the reaction tank 100 causing the oxidation reaction between the reagent and the organic matter, and the chemical oxygen demand (COD) according to the output value of the measuring device. The control unit 106 to determine the injection amount of each infusion pump (108, 110).;By periodically checking the concentration of the organic material introduced through the redox measuring apparatus and maintaining it constant, stable FENTON oxidation treatment is possible. In addition, the reagent ratio injected into the Fenton oxidation tank through the control unit is periodically calculated and the appropriate amount is injected to reduce the excessive reagent injection cost.
