<p><P>PROBLEM TO BE SOLVED: To provide a polluted water purification method which simplifies the configuration of a purification apparatus, improves a treatment capacity of water polluted by volatile organic compounds, and has an excellent removal efficiency. <P>SOLUTION: The polluted water purification method comprises an aeration tank 7, a plurality of aeration chambers 13-18 formed by dividing the aeration tank 7 with partition walls 8-12, fillers 19-24 each filling the aeration chamber, a blower (an air supply means) 25 for the aeration chambers, and adsorbents 43, 45 adsorbing the volatile organic compounds. The polluted water is made to flow sequentially into the aeration chambers to promote gas-liquid contact by the filler. The volatile organic compounds are transferred from the polluted water to air supplied into the aeration chambers, and then adsorbed by the adsorbents to be removed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
