摘要:
The improved method of treating an exhaust gas from a combustion apparatus comprises adding ammonia to the exhaust gas and then irradiating it with an electron beam, characterized in that part or all of said ammonia is supplied as a separated portion of ammonia-containing water. The ammonia-containing foul water may contain feces excreted from humans and/or domestic animals and poultry, fermentation industry liquid waste or food processing wastewater. The organic waste-containing water may be digested anaerobically to convert the organic matter to methane gas and, subsequently, ammonia is separated from the supernatant liquor and used as the source of ammonia to be supplied. The methane gas is suitably used as a source of energy for the combustion apparatus. At least part of the organic matter in the organic foul water may be decomposed oxidatively and, subsequently, ammonia is separated for use as the source of ammonia to be supplied. The method is capable of simultaneous treatment of the exhaust gas and the ammonia-containing water in an efficient economical manner.
摘要:
There is disclosed an enhancer for the antianemia effect of erythropoietin using a spherical carbon as an active ingredient in an amount effective for treating anemia in combination with erythropoietin. The enhancer is orally administered. The antianemia effect of erythropoietin can be remarkably enhanced, the dosage of erythropoietin can be remarkably decreased, and side effects from erythropoietin can be remarkably reduced. There is further disclosed a method of augmenting the antianemia effect of erythropoietin by administering to a patient an effective amount of a spherical carbon in combination with a portion of an effective amount of erythropoietin for treating anemia.
