The present disclosure provides a phase inversion pore-forming agent and a pore-forming method for a fly ash-based ceramic flat membrane support. The phase inversion pore-forming agent includes poly(oxyphenylene sulfone) and N-methylpyrrolidone (NMP), and is used in a preparation process of the fly ash-based ceramic flat membrane support. Pores can be formed through phase inversion, forming straight-through pores with gradient distribution inside the ceramic flat membrane support, thus avoiding a low porosity, a poor water flux, and uneven pore formation of the existing fly ash-based ceramic flat membrane support.
