Title: Method for processing waste water, method for regenerating adsorbent and waste water processing facility
Inventor: TAKAHASHI KAZUYOSHI
IPC: C02F1/32
Filed: 2000-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for processing waste water, a method for regenerating an adsorbent and a waste water processing facility such that the life of the adsorbent can be extended and the decrease in the adsorption performance of the adsorbent with time can be sufficiently prevented. SOLUTION: In the method for processing waste water by adding an oxidizer to waste water containing harmful substances and by passing the water through an adsorbent which can adsorb the harmful substances, the adsorbent is irradiated with UV rays in the waste water to which the oxidizer is added. Ozone or the like is used as the oxidant, and active alumina or the like is used for the adsorbent. By irradiating the adsorbent with UV rays in the waste water, OH free radicals necessary for oxidative decomposition of the harmful substances are produced. However, since a material which hardly reacts with OH free radicals is used as the adsorbent, the life of the adsorbent can be extended. The OH free radicals efficiently react with the harmful substances adsorbed to the adsorbent and can efficiently oxidatively decompose the harmful substances.
