| titleOfInvention | Method for preparing calcium phosphate using wastewater |
| abstract | The present invention relates to a method for producing calcium phosphate using wastewater, and more particularly, a calcium carbonate input step of adding calcium carbonate to wastewater generated during the production of phosphoric acid using phosphate ore, and a precipitate generated from wastewater into which calcium carbonate is added. It consists of a precipitation step of precipitating, a supernatant collection step of collecting the supernatant of the wastewater that has undergone the precipitation step, a calcium hydroxide input step of introducing calcium hydroxide into the collected supernatant, and a filtration step of filtering the supernatant with calcium hydroxide. |
