  We have performed a spectral decomposition to search for recoiling
supermassive black holes (rSMBH) in the SDSS QSOs with $z<0.25$. Out of 1271
QSOs, we have identified 26 rSMBH candidates that are recoiling toward us. The
projected recoil velocities range from $-76\ \kms$ to $-307\ \kms$ with a mean
of $-149\pm58\ \kms$. Most of the rSMBH candidates are hosted by gas-rich
LIRGs/ULIRGs, but only 23\% of them shows signs of tidal features suggesting
majority of them are advanced mergers. We find that the black hole masses
$M_{BH}$ of the rSMBH candidates are on average $\sim$5 times smaller than that
of their stationary counterparts and cause a scatter in $M_{BH}-\sigma_*$
relation. The Eddington ratios of all of the rSMBH candidates are larger than
0.1, with mean of 0.52$\pm$0.27, suggesting they are actively accreting mass.
Velocity shifts in high-excitation coronal lines suggest that the rSMBH
candidates are recoiling with an average velocity of about $-265\ \kms$.
Electron density in the narrow line region of the H II rSMBH candidates is
about 1/10 of that in AGN rSMBH candidates probably because AGN in the former
was more spatially offset than that in the latter. The estimated spatial
offsets between the rSMBH candidate and center of host galaxy range from
0.21\as \ to 1.97\as \ and need to be confirmed spatially with high-resolution
adaptive optics imaging observations.
