Abstract
PURPOSE: To efficiently remove an arsenic in waste water by curing the coprecipitate of the arsenic with calcium hydroxide or the like under the condition that it is not brought into contact with carbon dioxide gas after the coprecipitate is collected when the arsenic in the waste water is coprecipitated with the calcium hydroxide or the like to be removed from the waste water and reusing it in the treatment of the waste water.
