Abstract
PURPOSE: To adsorb and remove N and P compounds containing in waste water, causing an enrichment of nutritive substance at the same time, by contacting the waste water containing two kinds or more of NO3 -, NO2 -, PO4 3- with chelate ion exchange resin adsorbed metal ion except alkali (earth)metal previously.
CONSTITUTION: Waste water containing two kinds or more of each ion, is contacted with chelate ion exchange resin mainly adsorbed heavy metal ions, such as iron, Al, Ti, Co etc., previously and N and P compounds in the waste water are adsorbed and removed. For example, ion exchange resin whose resin structure is phenol condensate and chelate forming functional group is iminodiacetate etc., is used for the chelate ion exchange resin of the above occasion.
