| titleOfInvention | Waste water treatment method and waste water treatment equipment |
| abstract | Disclosed is a wastewater treatment method and a wastewater treatment apparatus capable of stably removing fluoride ions and suppressing sludge generation in wastewater treatment containing magnesium ions and fluoride ions. An alkaline agent addition device for adding an alkaline agent to wastewater containing magnesium ions and fluoride ions, the wastewater and the alkaline agent are reacted, and the fluoride ions are added to the generated magnesium compound-containing precipitate. The treatment tank 10 to be adsorbed, the solid-liquid separation tank 14 for solid-liquid separation of the waste water containing the sludge containing the magnesium compound-containing precipitate and the treated water, and the fluoride ion electrode potential of the waste water containing the magnesium compound-containing precipitate. The amount of the alkali agent added to the alkali agent adding device is controlled so that the fluoride ion electrode potential measured by the fluoride ion electrode 24 and the fluoride ion electrode potential measured by the fluoride ion electrode 24 become a preset target value. A waste water treatment apparatus comprising: [Selection] Figure 1 |
