Air pollution in Penghu County is affected by Taiwan and abroad. The local pollution, in addition to industrial and transportation sources, is mainly caused by increased crowds during the tourist season. The county's PM10, PM2.5, and ozone air quality are affected by overseas pollution, showing high concentrations in winter. In summer, the concentration is low, and the concentration of SO2 and NO2 is high in summer. The overall air quality status was found from the 105-108 AQI change trend of Magong Station. The good ratio of 0-50 increased, and the bad ratio of 100-150 decreased from 6.3% in 105 to 5.8% in 108. This shows that the county's air quality continues. Improvement. The average value of PM2.5 (continued three times) is less than the average value of air quality standards, and continuous improvement is expected to reach the target of secondary control zone next year.
In response to the Environmental Protection Agency's announcement of the emissions inventory TEDS10.0, complete the county's emissions inspections, and for exposed surface and agricultural operations, quote conversion factors suitable for the county and estimate revised emissions to provide a reference for the development of regulatory strategies. Completion of the expert sub-plan inspection and assessment of members of the air purifying zone, each member provided valuable opinions as a reference for the improvement of various tasks.
The 108-year implementation results of the county's various control strategies are summarized as follows: Coastal afforestation has been promoted year by year from 1981, from 99 (1,961 hectares) to 108 (2,236 hectares), with an additional afforestation of 275 hectares; associated county offices Resources jointly promote greening and beautification of the environment, reduce wind and dust emissions from exposed areas, and match 4 air quality purification zones for adoption by private enterprises. In 108, Jianshan Power Plant won the Silver Award for Excellent Contributions from Excellent Advocacy Units. The average control efficiency of the SCR equipment of Jianshan Power Plant was improved. After counseling the operators to implement the maintenance of the control equipment and the addition of urea, the SCR control efficiency reached 74.9%. In 108 years, 679 two-stroke locomotives have been decommissioned, with a target of 517. The decommissioning rate is as high as 131.3%, and the decommissioning rate reaches the sixth place in the country. Since the announcement of the subsidy measures for the elimination of old large-scale diesel vehicles in 106, the cumulative number of decommissioning of old large-scale diesel vehicles for the first and second phases up to 108 years has reached 203, and the target of decommissioning for 106-108 years is 196 (cumulative decommissioning) (Achieved rate of 110%), eliminated a total of sixth place in the country. In March 108, in cooperation with the bureaus of the county government, a “Joint Inspection Team for Public Safety in Business Places” was set up to actively counsel the open-air barbecue industry to improve various deficiencies. A total of 13 companies have added fume control equipment, and the remaining 7 companies have ceased operations themselves. Improved oil fume prevention equipment; installed effective oil fume prevention equipment in the open-air barbecue industry. The total air pollutant reduction was PM10 0.72 metric tons / year, PM2.5 0.5 metric tons / year, NMHC 2.84 metric tons / year, and the reduction ratio was 107 5% has grown significantly to 75% in 108, and the installation rate of defense equipment has reached 65%, an increase of more than 10 times compared to 107. There were 9 cases of publicity in the construction project in 107 years and 8 cases in 108 years. The number of cases of publicity decreased by 11%, indicating that the district's patrol control strategy and on-site counselling can reduce the occurrence of disturbing and publicity cases.
