Abstract: Emissions of volatile organic compounds (VOCs) from a domestic waste incineration power plant in Henan Province, China were characterized to evaluate its contribution to ozone generation. VOCs samples were collected via air bags, Summa canisters and adsorption tubes. The concentrations of 117 VOCs species were analyzed by GC-MS & HPLC-MS to calculate VOCs emission factors. The maximum incremental reactivity (MIR) method was used to calculate the ozone formation potential (OFP) and to identify the components that contribute significantly to OFP. The results show that: (1) The VOCs concentration at the stack was 4.28 mg/m³, corresponding to a total VOCs emission of 3.5 t/a and a localized emission factor of 0.016 g/kg domestic waste. (2) The estimated OFP amount and the average MIR coefficient were calculated to be 9.3 t/a and 2.67, respectively. (3) The mass fractions of main VOC groups such as aromatic hydrocarbons, halogenated hydrocarbons, oxygenated volatile organic compounds and alkanes were 38.37%, 28.79%, 14.32% and 12.75%, respectively. Whereas the major VOC groups of OFP contribution were aromatic hydrocarbons (53.91%) and oxygenated volatile organic compounds (28.16%). The top five species of OFP contributions were acetaldehyde (20.5%), m(p)-xylene (20.2%), n-butene (6.2%), 1,2,4-trimethylbenzene (5.4%), and n-butyraldehyde (4.9%). (4) The VOCs concentrations in the solid waste workshop, boiler workshop and landfill leachate pump workshop were 83.6, 6.19, and 5.71 mg/m³, respectively. The concentrations outside the boiler workshop and landfill leachate pump workshop were 1.24 and 1.79 mg/m³, respectively. Therefore, it is necessary to improve the collection of local VOCs emissions inside all the workshops due to their high VOCs concentrations to further reduce the unorganized VOCs emissions. Moreover, more advanced VOCs control device should be installed to further reduce VOCs emissions from the stack.
