Wood-ceramic electrocatalytic composite membrane and preparation method thereof

The invention belongs to the field of wastewater treatment, and discloses a wood-ceramic electrocatalytic composite membrane and a preparation method thereof. The preparation method comprises: carrying out high temperature carbonization treatment on cheap and easily-available wood materials generally existing in the nature to obtain a raw material, crushing to obtain charcoal powder with differentparticle sizes, respectively immersing the charcoal powder with different particle sizes in an electric-conduction metal oxide sol and a catalyst sol, carrying out drying heat treatment, uniformly mixing with an epoxy resin and butyl titanate in a ball mill, molding, drying, and sintering to obtain the graded porous electrocatalytic composite membrane with electric conductivity, wherein the micro-pore structure and the nano-pore structure are matched in the graded porous electrocatalytic composite membrane, and an electrocatalytic composite membrane reactor is constructed by using the electrocatalytic composite membr
