The application discloses a solid preparation for dialysis and a preparation method thereof. The solid preparation comprises sodium chloride, potassium chloride, calcium chloride, magnesium chloride and a pH regulator. The sodium chloride is located in an inner layer of the preparation, the potassium chloride, the calcium chloride and the magnesium chloride are located in a middle layer of the preparation, and the pH regulator is located in an outer layer of the preparation. The pH regulator comprises glucose acid and sodium citrate. The three-layer design of the preparation not only solves the deliquescence problems of the calcium chloride and the magnesium chloride, but also solves the stability problem of the preparation. In addition, the porous sodium chloride with uniform granularity and porosity is used in the inner layer, so that the solid preparation with uniform granularity can be formed.
