<p><P>PROBLEM TO BE SOLVED: To provide a waste water treatment apparatus capable of both removing phosphorus by an electrochemical reaction means and decomposing organic matter by a biochemical reaction means over a long period of time in treatment of organic electrolyte waste water containing phosphate ions and phosphate compounds, while only phosphorus removal has been carried out conventionally by an electrochemical reaction means having a cell function. <P>SOLUTION: The waste water treatment apparatus comprises an air cell having a metal anode and a cathode of a carbon material such as black coal, hard charcoal, graphite or the like, which functions as both an electrochemical reaction means and a biochemical reaction means with the charcoal cathode serving as an organism carrier for an aerobic biological treatment tank in the treatment of organic electrolyte waste water containing phosphate ions or phosphorus compounds. The apparatus is also provided with a dissolved oxygen feeding means and a stirring means for efficiently continuing the electrochemical reaction and biochemical reaction, and a solid-liquid separating means for post treatment of the electrochemical reaction and biochemical reaction. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
