pollution control Chemical and physical methods to lessen discharges of most pollutants; for carbon dioxide there is, at present, no economic or practical way to reduce the quantities discharged except by reduced fossil fuel usage. Most specific means for removing pollutants from emissions include flue-gas desulphurisation, fluidised combustion, catalytic converters and the redesign of equipment, such as furnace burners and car engines, to lessen the production of pollutants (使用化学和物理的方法来减少污染物的排放，主要是二氧化碳的排放；目前还没有经济、实用的方法来减少化学燃料的使用及其造成的污染排放量。大多数对污染物排放的处理包括烟气脱硫、流化床、插入燃烧、催化转换器和重新设计的设备，如炉燃烧器和汽车发动机，以减少污染物的产生。); damage control |
