摘要： Effluent gas containing SO.sub.2 and/or nitrogen oxides of various forms (referred to as NO.sub.x) are irradiated with an ionizing radiation to form aerosol. The aerosol is collected by a collecting means to form a collected material containing sulfur dioxide and nitrogen oxides. Effective components are recovered from the collected material by subjecting it either to steam-roasting with or without addition of ore of low grade, solid waste generated from smelting processes, copper-containing pyrite cinders or an alkali earth metal compound to the collected material, or to thermal decomposition.

摘要： Removal of gaseous pollutants such as nitrogen oxides and sulfur dioxide from effluent gases can be carried out advantageously from an industrial viewpoint by effecting irradiation of said gases under specifically selected conditions. High dose rate electron beam irradiation at a dose rate in the region of 10.sup.5 rad/sec or higher is, unexpectedly, remarkably effective and efficient for said purpose. Irradiation under increased pressure is also preferable. Wash of gases after irradiation or effecting irradiation in the presence of water vapor is effective especially for the removal of nitrogen oxides. Further, by carrying out the process in two-steps in which nitrogen oxides are removed from such gases almost completely by irradiation with the minimum dose of electron beams before sulfur dioxide is removed from the thus treated gases by conventional desulfurization means, the process can be carried out very economically. Thus, it has become industrially feasible to treat the effluent gases with irradiation, for the removal of nitrogen oxides and sulfur dioxide before releasing them into the atmosphere.
摘要翻译：从工业的观点出发，可以有利地从流出气体中除去气体污染物如氮氧化物和二氧化硫，在特定条件下进行所述气体的照射。在105rad / sec或更高的范围内的剂量率的高剂量率电子束照射意外地对于所述目的而言是非常有效和有效的。加压下的照射也是优选的。在水蒸汽存在下，照射后或进行照射后的气体洗涤对于除去氮氧化物是有效的。此外，通过在通过常规脱硫装置从这样处理的气体除去二氧化硫之前通过用最小剂量的电子束照射几乎完全从这些气体中除去氮氧化物的两个步骤进行该步骤，该方法可以是非常经济地进行。因此，在将其排放到大气中之前，通过照射来处理废气已成为工业上可行的去除氮氧化物和二氧化硫。

摘要： Sulfur dioxide and nitrogen oxides can be removed from effluent gases with increased efficiency by blowing contaminated air present in the irradiation room into a stream of the effluent gases before the mixture is delivered to a reaction chamber to be irradiated with an ionizing radiation or ultraviolet light. This provides also a convenient process for purifying the contaminated air containing nitrogen oxides and ozone before release into the atmosphere. Thus, simultaneous purification of industrial effluent gases and contaminated air is advantageously carried out.
摘要翻译：在将混合物输送到反应室中以用电离辐射或紫外线照射之前，通过将存在于照射室中的污染空气吹入流出气体流中，可以通过提高效率从流出气体中除去二氧化硫和氮氧化物。这也为排出大气中的氮氧化物和臭氧净化污染空气提供了便利的方法。因此，有利地进行工业废气和污染空气的同时净化。
