Abstract

The invention belongs to the technical field of industrial water treatment and relates to a method and treatment system for reducing the silicon content in industrial water. The method for reducing the silicon content in industrial water utilizes compounding and adding of several agents for treatment and comprises adding a silicon removing agent into raw water to be treated, carrying out uniform mixing, adding a flocculant A into the mixture, carrying out uniform mixing, optionally adding a flocculant B into the mixture, and carrying out precipitation and filtration to reduce the silicon content of the water. The silicon removing agent comprises an alkali metal compound and / or an alkaline earth metal compound. The flocculant A includes an inorganic high-molecular flocculant. The flocculantB includes an organic polymer flocculant. The method and system can effectively reduce the silicon content in the raw water and effectively relieve the silicon removal load in the primary desalination water station system. The method has simple processes, is easy to operate and has good treatment effects.

Description

technical field

[0001] The invention belongs to the technical field of industrial water treatment, and in particular relates to a method and a treatment system for reducing silicon content in industrial water. Background technique

[0002] Silicon compounds in industrial water will cause different degrees of harm to the production process. The water standard for industrial boilers has strict restrictions on the content of silicon. Most of the silicon in the water must be removed before entering the boiler. Silica scale is dense and hard, which is difficult to clean by ordinary methods, which seriously affects the heat transfer efficiency and safe operation of the equipment, and easily brings hidden dangers to production safety. In thermal power plants, silicic acid in water is a harmful substance. It will not only form scale on the furnace tubes with high heat load, but also cause salt accumulation on the turbine blades, resulting in failure of boilers and turbines. Foulin...
