Abstract: Technique situation of removal of SO₂ and NO_x is described,and conclusions as follows were drawn through analysis and comparison.The investment and running cost of SO₂ removal in wet method is high and its byproducts are useless;on the contrary,the cost of SO₂ removal by use of electron beam is 20%～30% lower than that in wet method,but strict and giant radiation defensive facilities are needed with expensive accelerator and energy loss is great.Also it is suggested that SO₂ in flue gas can be oxidized and solid particles of (NH₄)₂SO₄ are generated by using strong barring dielectric discharge which is hopeful to resolve the pollution of SO₂ and NO_x in China.
