Title: Waste water treatment apparatus and waste water treatment method
Inventor: KURISU HARUO
IPC: C02F3/34
Filed: 2003-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a waste water treatment apparatus and a waste water treatment method with which an increase in the load on a nitrification tank and the reduction of the size and total cost of facilities are made possible.  <P>SOLUTION: The waste water treatment apparatus 10 is equipped with the hermetically sealable nitrification tank 12 which subjects the ammonia nitrogen in the waste water introduced therein to oxidation treatment to nirate nitrogen by nitrifying bacteria, an oxygen supplying means 14 which supplies pure oxygen or oxygen-rich gas into the nitrification tank and an aerating means which captures the gas of the space between the liquid level of the waste water in the nitrification tank and the ceiling section of the nitrification tank and aerates the gas to the waste water in the nitrification tank in order to promote the dissolution of oxygen to the waste water in the nitrification tank. In the configuration, the dissolution rate of the oxygen into the waste water is enhanced and a nitrification reaction can be promoted by supplying the pure oxygen into the hermetically sealed nitrification tank to aerate the waste water. Even more, reactive gas is not generated and therefore there is no need for opening the nitrification tank and the supply of pure oxygen of only the required amount suffices and a running cost can be held down low.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
