An engine exhaust gas treatment system and method. The engine exhaust gas treatment system comprises an exhaust gas dust removal system and an exhaust gas ozone purification system; the exhaust gas dust removal system comprises an exhaust gas electric field device (1021) and an exhaust gas cooling device; the exhaust gas electric field device comprises an exhaust gas electric field device inlet, an exhaust gas electric field device outlet, an exhaust gas dust removal electric field cathode (10212), and an exhaust gas dust removal electric field anode (10211), wherein the exhaust gas dust removal electric field cathode (10212) and the exhaust gas dust removal electric field anode (10211) are used for generating an exhaust gas ionizing dust removal electric field; and the exhaust gas ozone purification system comprises a reaction field (202) which is used for mixing an ozone stream with an exhaust gas stream to react. The present engine exhaust gas treatment system may effectively remove particulate matter from the engine exhaust gas and has a better purification and treatment effect on the engine exhaust gas. |
