Summary
This summary is machine-generated.Municipal waste incineration (MWI) generates volatile organic compounds (VOCs). A study found that air pollution control devices (APCDs) effectively reduce VOC emissions by 77.5%, crucial for urban air quality.
Area Of Science
- Environmental Science
- Chemical Engineering
- Air Pollution Control
Background
- Urbanization drives increased municipal waste incineration (MWI).
- Volatile organic compounds (VOCs) are a growing concern from MWI emissions.
- Effective control of VOCs is essential for urban air quality.
Purpose Of The Study
- To investigate VOC emission characteristics from a Chinese MWI plant.
- To evaluate the removal efficiencies of a multistage air pollution control device (APCD) system.
- To quantify the impact of APCDs on overall VOC reduction.
Main Methods
- Conducted full-process VOC field sampling at a representative MWI plant.
- Identified 59 VOC species, categorizing them into alkanes/alkenes, aromatics, oxygenated-VOCs (O-VOCs), and halogenated hydrocarbons.
- Assessed the performance of activated carbon injection, fabric filters, and wet desulfurization.
Main Results
- The integrated APCD system achieved a total VOC removal efficiency of 77.5%.
- Synergistic removal efficiencies varied by VOC group: alkanes/alkenes (90.9%) > aromatics (87.0%) > halogenated hydrocarbons (61.3%) > O-VOCs (42.2%).
- The emission factor was reduced from (8.4 ± 2.1) × 10³ ng/g-waste without APCDs to (1.9 ± 0.6) × 10³ ng/g-waste with the APCD system.
Conclusions
- The multistage APCD system significantly mitigates VOC emissions from MWI plants.
- The current APCD system reduces annual VOC emissions by approximately 6.52 × 10⁴ g at the studied plant.
- Effective APCDs are critical for controlling VOC pollution in urban environments.

Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...
