description The invention belongs to the technical field of slime water treatment processes, and particularly relates to a system and method for improving the feeding concentration of a sedimentation filtration type centrifugal dehydrator. The method at least comprises the following steps: 1) feeding coal slime water into a first-section concentrator, and obtaining a first-section bottom flow product through concentration and classification; 2) pumping the first-section underflow into a hydraulic classification cyclone through a first-section underflow pump, and concentrating again to obtain a cyclone underflow product; 3) removing impurities from the cyclone underflow product through an impurity removal sieve bend to obtain an undersize product; 4, the undersize product enters a sedimentation filtration type centrifugal dehydrator to be dehydrated, and a dehydrated product serving as a first middling coal product is obtained.According to the technical scheme, the feeding concentration of the sedimentation filtration typ
