Problems solved by technology

[0005] Although some progress has been made in the above research, on the one hand, it is impossible to solve the current relative shortcomings of traditional photocatalytic materials such as insufficient efficiency, insufficient lifespan, non-pollution resistance, and high lighting requirements (cannot be used normally day and night, and are difficult to apply in relatively shading places), etc. On the other hand, the combination of photocatalytic technology and ecological treatment methods has not been studied, resulting in the failure to exert the comprehensive effect of photocatalytic technology in environmental governance, but only limited to reducing the use of fungicides , which has affected the practical application of photocatalytic technology in industrial circulating water treatment

Description

technical field [0001] The invention relates to the field of environmental purification, in particular to the application of a multilayer composite functional material in the stable treatment of industrial circulating water. Background technique [0002] Photocatalytic oxidation of nano-titanium dioxide is a new water pollution control technology. It can effectively treat organic matter in water and kill harmful microorganisms in water. Since this technology is characterized by the use of sunlight, the degradation speed is fast, the oxidation conditions are mild, and there is no secondary pollution. It has a wide range of applications and high chemical activity of titanium dioxide, which is safe. It is non-toxic and cheap, so it is also called a green and environmentally friendly water treatment technology. [0003] In the industrial circulating water system, in order to solve the problems of system scale and corrosion inhibition, sterilization and algae killing, etc., the ...
