RESEARCH ADVANCES OF AIR POLLUTION AND CONTROL TECHNOLOGIES IN JAPAN

This article introduces the current situation and trends of air pollution in Japan in great detail, analyses the pollution s tuation of main contaminants and generalizes the research advances of air pollution prevention and treatment technolgies of dozens of years in Japan. It gives a minute introduction to air pollution prevention and treatment technologies such as improvement of burning, electron-beam method, research of NOx treating catalyst, research of NOx absorbent, dry type desulf urization of activated carbon method, dry type desu-Ifurization with coal, semidry type simple desulfurization, application of static electricily, application of microorganism, electrical dedusting and dedusting by screening. In addition, the article explores the fluorine containing emission control issue of the public's concern at present, and forwards a brief introduction to the research situation of gross motor emission control which is planned to be put into effect at Osaka and other places in Japan.
