ABSTRACT:
The present invention aims at providing an economical process for purifying water which can produce clean water by treating polluted water, which contains agricultural chemicals, organic solvents (particularly, halocarbon) and surface active agents (particularly, those with side chains) which are hard to treat according to a conventional activated sludge process, under moderate conditions readily and promptly, and also, which process is characterized by adding titanium oxide and iron salt into water to be treated, and irradiating light thereupon.
