Air pollutions caused by combustion gas emission are becoming one of the most serious problems particularly in the industrial areas. The research is focused on the treatment of NOx with lower cost performance by the plasma chemical reaction in corona discharge space. The DC corona and the AC barrier reactors were investigated for the application to NOx treatment in the smaller scale boiler or engines with lower cost performance. We designed the DC corona reactor with water for the application to both dust particle and NOx treatment, and got the better NOx removal results than the dry type. We confirmed that ozone and OH radical produced in the discharge plasma space were effective to proceed with the plasma chemical reactions for NOx removal processes. The optimal discharge conditions of the reactor were discussed by the result of NOx treatment test with the various distance between the upper and the lower electrodes. One of the results, more than 95% of the dust removal rate was confirmed 20mm of interelectrode distance by the diesel exhaust gas treatment test
