Title:
WATER TREATMENT METHOD BY CATALYZING OZONE WITH A PERSULFATE
Document Type and Number:
WIPO Patent Application WO/2012/155823
Kind Code:
A1
Abstract:
A water treatment method by catalyzing ozone with a persulfate comprises the following steps: introducing the ozone into an ozone contact reactor filled with water to be treated; at the same time putting the persulfate into the reactor, wherein a stirring state is kept in the water treatment process.The method solves the problems of difficulty in the ionization of hydrogen peroxide, low capability in inducing the decomposition of the ozone, high hydrogen peroxide residues and inconvenience of hydrogen peroxide transportation and storage existing in the conventional water treatment method for catalyzing the ozone by using the hydrogen peroxide. Hydroxyl radicals and sulfate free radicals with strong oxidizing properties, which are generated by catalyzing ozone with the persulfate, are oxidized to remove pollution, so that the method has the advantages of high catalytic capability, high oxidative degradation efficiency, wide pH application range, a small amount of catalyst residues, convenience of operation and the like, and can be applied in mass production.
