If the violation are few in mumbers. Try to do manual adjustment on the routing,

If it is huge in number, try to find the reason why it is occuring, ex: try to place your Blocks and Std cell optimally or try to change the floorplan to have more routing area for the signals

From your description( pure std cell design), I presume that the pre route drc violations are at the model pins.

If so, please check, whether the model pins and the power mesh are properly placed and spaced.
