The analysis of using dejectas collecting device in passenger train

摘要

Recently, as our country's rail network scope has been enhanced, the quality of traveling train has already been increasing in our country. Most trains emitted directly the pollutant to the railroad. It directly influences the environmental health of railroad along the line. The study of closed dejectas collecting device is helpful to improve environment pollution and health level of people. This paper focuses on analysis of the applicable conditions and model selection of closed dejectas collecting device, technical transformation of dejectas collecting device which used in accelerated train, and the care and maintenance of closed dejectas collecting device. Finally, the author gave some pieces of advice about the pollutant emission of the minitype train.
