The invention relates to a method for inhibiting generation of bromate through catalytic ozonation, belonging to the technical field of drinking water purification. The method comprises the following steps: forming a catalytic ozonation system from composite graphene active carbon as a catalyst to quickly generate a large quantity of hydroxyl radicals so as to quickly degrade organic matters and inhibit generation of bromate. The method has the characteristics that a novel carbon material, namely composite graphene active carbon can be used for performing the catalytic ozonation, the effect of inhibiting generation of bromate is remarkable, and the effect of removing other organic matters from water is good in comparison with that of independent ozone; the method is simple and convenient to operate, efficient and environment-friendly, and can be used for purifying drinking water.
Description
Technical field [0001] The present invention involves a method of catalytic ozone inhibitory bromine production, which is the field of drinking water purification technology. Background technique [0002] With the rapid development of the industry, the problem of water environmental pollution has become increasingly serious. At the same time, the safety of drinking water has also become the focus of attention.Ozone (O 3 ) As a strong oxidant, it can effectively oxidize organic matter and inorganic objects, which are often used in the purification of tap water.However, it is difficult to completely remove the TOC and COD in water during ozone oxidation, and even some disinfection products that harm the human body such as bromate.Bromate (BRO 3 - ) It has carcinogenicity and genetic toxicity, mainly due to bromine water source during ozone oxidation.The U.S. Environmental Protection Agency, the World Health Organization and the International Cancer Research Association have listed...
