Abstract: The VOCs at the organized emission outlets of key VOCs emission enterprises in Jinan wasmonitored by a portable nonmethane hydrocarbon analyzer. The emission characteristics of nonmethanehydrocarbons ( NMHC) in different industries and processes were analyzed,and the current treatmenttechnologies of VOCs were introduced. The results showed that the NMHC concentration of organized e-mission was ≤12 800 mg /m3,and the rate of exceeding the standard was 11.9%. The NMHC concen-tration discharged from coking process was the highest of all,reaching 868.25 mg /m3. The most usedtechnologies in key VOCs enterprises were actived carbon adsorption and UV photocatalysis. 66.4% ofenterprises adopted a combined process to treat VOCs. The application proportion of combined processof activated carbon + UV photocatalysis and adsorption-desorption + combustion reached 52.7%. Close-
