1. Project Background of Textile Industry Air Pollutant Emission Standard
It’s very important to deal with air pollution effectively and enhance discharge standards for industries releasing air pollutants as PM2.5 has become a more and more serious problem in China. Half of the PM2.5 volume is released directly into the air, while the rest is formed through physio-chemical reactions. As one of the original compositions of PM2.5, VOCs produce nitrate, sulphate, secondary organic aerosols etc. through chemical reactions induced by sunlight and heat, which are all contributors of PM2.5 volume. As the textile and dyeing industry generated VOCs accounted for a great proportion of industrial VOCs discharge amount, the development of the Textile Industry Air Pollutant Emission Standard is initiated in line with the newly released Air Quality Standard (GB 3095-2012).
