Abstract

The invention relates to a purification material for controlling air pollution. A biomass microsphere is formed through a colloidal biomass material loaded catalyst, and colloidal biomass is formed through starch and plant fiber gumming; the catalyst is a doped titanium dioxide-silica gel catalyst. The purification material mainly adopts the biomass material, the cost is low, environmental friendliness is achieved, and secondary pollution cannot be caused by using the material. The preparation method can be continuously implemented, implement and control are conducted easily, and industrial production is facilitated.

Description

technical field [0001] The invention relates to a purification material for controlling air pollution. Background technique [0002] In my country, in recent years, with the accelerated development of urbanization and the rapid development of industrialization, modern industry, transportation, construction, transportation, communication and high-end service industries in cities have brought rich material and spiritual products to urban residents. However, due to dense urban population, industrial agglomeration around the city and overload of urban transportation, the urban environment is increasingly damaged, especially air pollution. Pollutants discharged into the urban atmosphere due to industry, vehicle exhaust, and residents’ living conditions are increasing year by year. Due to the extremely limited urban space, huge energy consumption and high pollution caused by overcapacity, the city cannot perform its self-purification function. In addition, the chemical compositio...
