Abstract
Electron beam irradiation step is followed by alkaline material atomizing step in the present invention. Since irradiation step and alkaline material atomizing step is conducted in different time and in different reactors, the construction cost of X-ray shielding concrete is decreased remarkably. If the humidity of incinerator effluent gas is more than 100 g/Nm.sup.3 in dry basis by adding a steam of 110.degree..about.200.degree. C., harmful substances are efficiently removed by electron beam irradiation. As a result, it is possible to realize a space-saving equipment, a reduction of required energy, a simple operation controlling, and a prevention of occurrence of secondary environment pollution.
