| titleOfInvention | A water treatment method for strengthening persulfate oxidation |
| abstract | The invention discloses a water treatment method for strengthening persulfate oxidation. The water treatment method comprises: adding medicament to the water to be treated and controlling the pH value of the system to be above 7, and the medicament includes copper compound and persulfate , fully stirred and mixed to realize the oxidation treatment of pollutants in water; the copper compound refers to a monovalent copper compound and/or a divalent copper compound; Sulphate; in the described to-be-treated water, the addition concentration of Cu(I) and/or Cu(II) in the copper compound is controlled to be 0.01-100 mg/L, and the molar equivalent ratio of the persulfate and the pollutant in the to-be-treated water is 0.5-20:1. The invention provides a safe, efficient, stable and economical persulfate advanced oxidation advanced treatment method, which greatly improves the oxidation removal efficiency of pollutants, reduces the risk of heavy metal leakage and residue, significantly reduces investment and operation costs, and ensures water quality safety. |
