Air pollution in Penghu County is affected by both local and foreign sources. In addition to industrial and traffic sources, local pollution is mainly caused by the increase in the tourist season. The air quality of PM10, PM2.5 and O3 in this county is affected by foreign pollution, showing high concentrations in winter and summer. The concentration trend is low, and the concentration of SO2 and NO2 is higher in summer. The overall air quality of Magong Station (AQI more than the one hundred) has a trend of improvement year by year; the average value of PM2.5 manual measurement stations for three consecutive years (2017-2019) has been lower than the air quality standard and reached the level of the secondary prevention zone, but O3_8hr Continued efforts are still needed to reach the target.
In response to the Environmental Protection Agency’s announcement of the emission inventory TEDS10.1, the Penghu County emissions inspection operation was completed, and the revision proposal was submitted to the Environmental Protection Agency and updated to TEDS10.1. The plan collects the 2017-2020 reduction results and estimates the 2019 emissions , Provide reference for the development of control strategy.
The relevant bureaus of the county government have jointly promoted environmental beautification and reduced wind erosion and dust emissions from exposed areas. The area of green grass gardens per person has increased from 8.85 m2/person in 1999 to 11.8 m2/person in 2020; 4 air quality purification areas have been matched. Adopted by private enterprises; improve the average control efficiency of SCR equipment in Jianshan Power Plant, and counsel the industry to implement control equipment maintenance, catalyst bed renewal and urea addition. In 2020, the overall SCR average NOx emission concentration was about 256 ppm; January to April 2020 The number of locomotives to be eliminated in the period is 3,586, and the obsolescence rate is 16.3% (target 10%); the obsolete diesel locomotives are obsolete and the target is 36, and 63 vehicles have been eliminated. The obsolescence rate reached 175%, which is quite effective ; There are 14 open-air barbecues in operation and 14 oil-fume prevention equipment installed, with an installation rate of 100%, and 2-3 times a week intensified inspection operations. 14 inspections have been completed for barbecue operators in Magong City operation.
