Abstract
PURPOSE: To effectively separate turbid substance from waste water containing the turbid substance and a phosphorus component by precipitation without generation of fine phosphate precipitation, by adding a soluble iron salt and/or Al salt in company with a soluble Mg salt and/or Ca salt to the waste water.
CONSTITUTION: A soluble iron salt, e.g. ferric chloride, and/or a soluble aluminum salt, e.g. aluminum chloride or poly(aluminum chloride) (except their sulfates or sulfites) in company with a magnesium salt, e.g. magnesium chloride or magnesium hydroxide, and/or a calcium salt, e.g. calcium chloride or calcium hydroxide (except their sulfates or sulfites) is added to waste water containing turbid substance and a phosphorus component. Thereafter, the turbid substance in the waste water is coagulated and precipitated. The use rate of the iron salt and/or the aluminum salt is preferably 3W20 times or so, calculated as an anhydrous salt, by weight ratio to the rate of the turbid substance.
