A microwave-assisted method for preparing mixed solid acid from fishbone comprises the following steps: by taking fishbone solid waste as a raw material, rapidly carbonizing the fishbone solid waste in a microwave system to form fishbone biochar by utilizing the characteristics of selective heating of microwaves and wave absorption of organic matters in the fishbone, and enabling the whole fishbone to rapidly reach a molecular sieve activation temperature by utilizing the good wave absorption property of the biochar; thus, the fishbone solid acid is prepared. The fishbone solid acid prepared by the invention has dual characteristics of carbon-based solid acid and molecular sieve type solid acid, and can make up for the defects of the two solid acids. A wider thought can be provided for processing and application of the fishbone material. 一种微波辅助鱼骨制备混合型固体酸的方法，以鱼骨固废物为原料，利用微波的选择性加热和鱼骨中有机质可以吸波的特点，将其在微波体系下快速碳化形成鱼骨生物碳，并利用生物碳的良好吸波性使鱼骨整体快速达到分子筛活化温度，从而制备出鱼骨固体酸。本发明制备的鱼骨固体酸具有碳基固体酸和分子筛类型固体酸的双重特性，可以弥补两种固体酸的不足。可以为鱼骨材料的加工应用提
