| 摘要 |
The present invention is directed to a process of treating water contaminated with undesirable sulfides by adding chlorine dioxide to water in specified amounts and at specified rates of addition to oxidize the sulfides to sulfates and to simultaneously avoid or substantially retard the information of free colloidal sulfur therein. The invention is particularly useful for treating water which is or will be contaminated with petroleum oil containing undesirable sulfides, e.g., water-petroleum oil mixtures containing sulfate-reducing bacteria. |
