The invention discloses a tail gas treatment method. The method is implemented in equipment comprising a dynamic wave chilling tower, a Venturi tower, a recovery water tank and an intermediate water tank. A distributor with a plurality of Venturi tubes is arranged in the Venturi tower. The distributor divides the inner space in the Venturi tower into an upper part zone positioned above the distributor and a lower part zone positioned below the distributor. In the dynamic wave chilling tower, tail gas is subjected to first contact with a first washing liquid comprising a washing liquid from the lower part zone of the Venturi tower. In the lower part zone, the tail gas is subjected to second contact with a second washing liquid comprising a washing liquid from the recovery water tank and a washing liquid from the intermediate water tank. In the Venturi tubes, the tail gas is subjected to third contact with a third washing liquid comprising the washing liquid from the recovery water tank. With the above technical scheme, dust, corrosive gas HCL, nitrogen oxides and sulfur dioxide in the tail gas can be effectively removed, such that finally discharged tail gas can reach certain emission standards.
