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