Abstract: The phenomenon of equipment fouling is more common in the production and operation of coal chemical enterprises.
Among them, silica fouling is hard and difficult to deal with, which causes great harm to equipment. This paper described the
formation process and influencing factors of silica fouling, and analyzed the mechanism and technical characteristics of silicon
removal processes such as chemical anti-scaling method and process anti-scaling method.

Key words: coal chemical wastewater; silica fouling; influencing factors; silicon removal process
