Abstract
PURPOSE: To attain improvements of the quality of treated water, the miniaturization of treatment apparatus, and the saving of the amount of chemicals used by a procedure in which waste water is mixed with a Ca compound and then separated into solids and liquid, and then the effluent is mixed with an alkaline agent and then separated into solids and liquid.
CONSTITUTION: A waste water containing organics, nitrogen, phosphorus, etc., is mixed with a Ca compound, e.g., calcium chloride, quick lime, calcium carbonate, etc., in a biological treatment process and then subjected to a solid-liquid separation process, where the preferred amount of the Ca compound used is 1W5 times (as Ca ion) as much as phosphoric acid ion present in the waste water. Then, an alkaline agent, e.g., NaOH, KOH, quick lime, etc., is added to the effluent separated into solids and liquid by using a sand filter.
