A method for reducing dust removal electric field couplings includes the following steps: selecting a ratio between a dust collection area of a dust removal electric field anode and a discharge area of a dust removal electric field cathode to be 1.667:1-1680:1. A dust removal electric field anode and/or dust removal electric field cathode size is selected so that the number of electric field couplings is less than or equal to 3. The number of electric field couplings is reduced, electric field energy consumption is low, electric field coupling consumption for an aerosol, water mist, oil mist and loose smooth particulate matter is reduced, and electric field energy is saved.

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.
