    We propose a theoretical scheme for the implementation of a non-local quantum SWAP operation on two spatially separated entangled pairs by a three-qubit entangled state and a Bell state,and we show that the operation can swap two qubits of these entangled pairs. The feature of the scheme is that a third side is included,who may participate the process of quantum non-local implementation as a supervisor. Furthermore,when the quantum channel is partially entangled,the third one can rectify the state distorted by imperfect quantum channel.
