An engine tail gas treatment system, comprising a tail gas dust removal system and a tail gas ozone purification system. The engine tail gas ozone purification system comprises a denitration device (203) configured to remove nitric acid in a mixed reaction product of ozone and tail gas. The denitration device (203) comprises an electrocoagulation device (2031). The electrocoagulation device (2031) comprises an electrocoagulation flow channel, a first electrode (301) located in the electrocoagulation flow channel, and a second electrode (302). The electrocoagulation device (2031) has strong ability of collecting water mist containing nitric acid, and the efficiency is high. The engine tail gas treatment system can effectively remove particulate matters in the engine tail gas, and has better purification effect to the engine tail gas |
