| titleOfInvention | Wastewater Treatment Method and Wastewater Treatment System |
| abstract | Even if arsenic-containing wastewater includes an oxidizing substance, the arsenic can be reliably removed as a precipitate. A wastewater treatment method includes a preparation step (S 10 ) of preparing wastewater containing an oxidizing substance and arsenic, a feeding step (S 30 ), a precipitation step (S 50 ), and a post-treatment step (S 60 ). In the feeding step (S 30 ), as much FeCl 2 as necessary to reduce the oxidizing substances, such as polishing agents, is introduced into the wastewater. In the precipitation step (S 50 ), to precipitate out the arsenic as a precipitate from the wastewater as at least a part of the precipitating flocculant, FeCl 3 transformed from the FeCl 2 by its reducing the oxidizing substance is utilized. In the post-treatment step (S 60 ), the precipitate is removed from the wastewater. |
