ABSTRACT:
There are proposed a waste water treating method, a waste water treating appratus and a waste water treating system which are capable of treating a nitrogen compound and a phosphorus compound in the same treating vessel and treating waste water containing a nitrogen compound and a phosphorus compound efficiently. The waste water treating method is a method for treating a nitrogen compound and a phosphorus compound in for-treatment water by an electrochemical process, wherein a metal material constituting a cathode is a conductive material, a conductive material constituting an anode is an insoluble material or carbon, and there is carried out at lease one of a step of adding calcium chloride to the for-treatment water and a step of immersing an iron material in the for-treatment water.
