Spectral bandscan surveys at centimeter/millimeter wavelengths offer comprehensive assessment to the molecular inventory in molecular clouds and cores, which is vital, from both astrophysical and astrochemical viewpoints, to our understanding of these objects. Orion KL, the most well-known and nearest massive star-forming region, has been an archetypical object for spectral scan studies at nearly all millimeter wavelengths. For this reason, it has been chosen as the prime target for the science verification of ALMA Band 1 bandscan capability. We present the analysis of the spectroimaging results from the SV observations, including the detection of molecular species, the comparison with observational results obtained from single-element telescopes, and the apparent chemical differentiation among different types of molecular species.
