The invention belongs to the technical field of sewage treatment, and particularly relates to a high-performance MBBR biological carrier and a preparation process thereof. The high-performance MBBR biological carrier comprises a shell; a nano ferric oxide layer is arranged on the surface of the shell, the bottom end of the shell is connected with a traction rope, the bottom end of the traction rope is connected with a dissolving block which is dissolved in water, and the dissolving block can generate bubbles in water when dissolved; a nano ferric oxide layer is formed on the surface of the shell of the biological carrier in a chemical deposition manner, so that the surface property is changed, the hydrophilicity is greatly improved, and the infiltration time is shortened, thereby promoting the growth of microorganisms on the surface of the biological carrier; gas at the pores can form bubbles to emerge from the surface of the dissolving block, so that the dissolving block and the shell are promoted to flow in
