The invention relates to the technical field of preparation of solid oxygen-bearing bleaching agent, in particular to a solid hydrogen peroxide preparation technology. The preparation technology comprises the step of kneading sodium sulfate, hydrogen peroxide and salt in a kneader at a certain proportion to obtain the finished product. According to the invention, the ordinary 30% hydrogen peroxide can serve as a basic material, the problems that the preparation cost is higher, the mother liquor is not fully utilized and waste liquid is discharged in the prior art are solved, the yield of hydrogen peroxide in the obtained finished product is more than 80 percent, the process period is shorter, the cost is lower, no three-waste emission exists, and the solid hydrogen peroxide preparation technology is suitable for large-scale popularization and application.
