Process for preparing building material product by membrane separation coupling mineralization technology and application of process

The invention relates to the field of building material products, in particular to a process for preparing a building material product through a membrane separation coupling mineralization technology and application of the process. The process comprises the following steps: S1, carrying out membrane separation and trapping on flue gas to obtain high-concentration carbon dioxide-containing gas with certain humidity; and S2, mineralizing a green body prepared from the solid waste by adopting the carbon dioxide-containing gas obtained by membrane separation and trapping, so as to prepare a building material product. According to the technology for preparing the building material product through the membrane separation coupling mineralization technology, the membrane decomposition technology is coupled with the mineralization technology, a technical method for synergistically mineralizing and treating a large amount of solid waste is provided for enterprises with low-concentration carbon dioxide emission, the sol
