Abstract
PURPOSE: To produce insoluble salt, and remove and collect it, by mixing the waste water containing an inorganic and deleterious substance, with water in which solid alkali has been made effluent.
CONSTITUTION: The packed column 1 is packed with the granular solid alkali material consisting of a binding material such as calcium oxide, calcium carbonate and alumina, etc. The waste liquid containing an inorganic and deleterious substance such as model phosphoric acid solution, etc. is fed into the raw feed tank 4 from the raw water tank 3, and it is fed into the mixing tank 5 across the partition plate 6. On the other hand, a part of treated water or clean water is made to pass through the packed column 1, sold alkali is made effluent into water, and said water is fed into the mixing tank 5 from the flow rate control valve 9, and it is stirred and mixed. This mixing liquid is fed into the sedimentation tank 7, and it is discharged from the sludge discharge port 12 after sedimenting its inorganic and deleterious substance. The supernatant liquid is fed into the filter column 2, is filtered, a part of treated water is fed into the packed column 1, and the residual is made to flow. According to this treatment method, concentration of PO4 3-, etc. in treated water can be made approx. 1.0ppm or below.
