<p><P>PROBLEM TO BE SOLVED: To inhibit a growth of sundry germs and mold caused when condensed water droplets remain in oxygen enriched air supply piping, in a water purification apparatus having an oxygen enriching means in it. <P>SOLUTION: The water purification apparatus has the oxygen enriching means 2, an aeration tank 1 that stores sewage to be aerated, a supply means 3 for supplying oxygen enriched air obtained by the oxygen enriching means 2 to the sewage in the aeration tank 1. A reservoir 4 is installed in the middle of the supply means 3, which enables discharge of water staying in the reservoir 4. Thereby the growth of the sundry germs and the mold due to stay of the water droplets condensed in the oxygen enriched air supply piping without being discharged can be inhibited. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
