Description

technical field [0001] The invention relates to the technical field of decontamination paints, in particular to a corrosion-resistant and decontamination paint with high adhesion. Background technique [0002] With the enhancement of people's awareness of environmental protection, more and more people pay more and more attention to the pollution of organic matter in water bodies. In the past, the main treatment methods for organic matter pollution in water bodies were physical adsorption and microbial decomposition. However, these two methods have high investment and slow results. It is greatly affected by the external environment and cannot play a good role in dealing with organic pollution. At present, the use of activators to activate H 2 o 2 and O 2 Oxidants, such as oxidants, generate highly active free radicals in water bodies, thereby effectively oxidizing and degrading organic matter into low-toxic or non-toxic small molecules, and the new oxidation technology ...
