A bidirectional flow hydrogenophilic carbon dioxide methanation apparatus and method comprises two stages: cultivation and normal operation. Both stages include a dry biomethanation mode and a wet immersion mode on a biofilm carrier. In the dry biomethanation mode of the cultivation stage, cultivation is initially performed using an upward flow inlet, then switched to a downward flow inlet. During normal operation, a mixture of hydrogen and carbon dioxide is alternately introduced into the gas-phase reaction zone from both ends of the apparatus, flowing upwards and downwards. The biofilm, in a static, drained state, converts the hydrogen and carbon dioxide into methane and water. In the wet immersion mode on the biofilm carrier, the porous biofilm carrier is immersed in a nutrient solution, allowing the microorganisms attached to its pores and surface to obtain nutrients, promoting microbial growth and reproduction. This invention can improve biomass and carbon dioxide conversion efficiency under low-cost conditions, providing an effective pathway for carbon dioxide resource utilization.
