The utility model discloses an oil-water separation fine treatment tank which comprises a lower cylinder body, an upper cylinder body arranged on the lower cylinder body and a cylinder section arranged at the bottom of the lower cylinder body, and a fine treatment filter element assembly is arranged on the cylinder section; a liquid inlet communicated with the fine treatment filter element assembly is formed in the bottom of the lower barrel; a liquid outlet pipe is mounted at the top of the upper barrel; wherein a barrel cover is further mounted on the barrel section; and a rotational flow guide structure is mounted on the barrel cover. Through the arrangement of the rotational flow guide structure, the oil field output liquid can be guided in the rotational direction when flowing into the inner cavity of the tank body formed by the lower barrel body and the upper barrel body from the barrel cover, so that centrifugal force exists when the oil field output liquid enters the inner cavity of the tank body, and
