An engine emission treatment system incudes at least one out of an air inlet dust removal system ( 101 ), a tail gas dust removal system ( 102 ), and a tail gas ozone purification system. The tail gas dust removal system ( 102 ) has an inlet of the tail gas dust removal system, an outlet of the tail gas dust removal system, and a tail gas electric field device ( 1021 ). The tail gas ozone purification system has a reaction field ( 202 ), used for mixing an ozone stream and a tail gas stream for reaction. The engine emission treatment system may effectively treat engine emissions, so as to make the engine emissions cleaner. |
