By adopting a phenomenological broken power-law model, we obtain the upper limit of normalized energy density of SGWB generated by DWs in the peak frequency band $10\\sim200$ Hz, and get the most stringent limitation at the peak frequency $f_*=35$ Hz, namely $\\Omega_\\text{DW}(f_*=35\\,\\text{Hz})<1.4\\times10^{-8}$ at $95\\%$ confidence level (CL).
