| titleOfInvention | Method for treating wastewater containing harmful substances |
| abstract | A method for treating wastewater containing harmful substances including boron, the method comprising the steps of: (1) introducing slaked lime and phosphoric acid as treating agents into the wastewater containing harmful substances including boron; (2) reacting the treating agents with the harmful substances in the wastewater; and (3) carrying out solid/liquid separation after the reaction to remove a solid-phase component. In step (2), hydroxyapatite of which the pore volume peak appears in the pore diameter range from 10 to 100 nm and in which the pore volume at the peak is 1 cm3g or more is produced, and the harmful substances are enclosed in and adsorbed onto the hydroxyapatite. According to the treatment method, each of the harmful substances can meet the national minimum effluent standard thereof with smaller throughput compared with the conventional methods. |
