(1) Indoor air quality operations
In this plan, 30 indoor air quality inspection sites (the first and second batches) will be inspected this year, including the training of site management personnel, and on-site inspections will be conducted on a quarterly basis with a portable direct-reading instrument of carbon dioxide. The patrol inspection concentration is higher in hospital-type places, and the concentration range in other places is between 450 and 750 ppm. The concentration in school classrooms of non-pipelined places fluctuates between 800 and 950 ppm. At the same time, 5 of the 30 listed sites will be selected to conduct expert and scholar guidance on September 15 and provide site improvement suggestions. It is also planned to conduct inspections and on-site inspections for non-listed places in the county, including public middle school and elementary school classrooms, public kindergartens, parent-child pavilions, public private childcare centers, gymnasiums, underground parking lots, tourist factories, etc. In the online declaration part of listed sites, each site completes the declaration and regular inspections within the time limit.
(2) Operation and maintenance of air quality monitoring stations
Maintain the normal operation of manual air quality measurement stations (3 locations) and automatic measurement stations (2 locations) within the jurisdiction of the county to complete the collection and setting out of TSP, PM10, PM2.5, and falling dust twice a month for each of the three manual measurement stations. Maintenance work: The automatic measurement station part also completes the regular maintenance of 2 stations each twice a month, and the data availability rate is over 96%.
1. Manual station operation and maintenance operations and monitoring results
TSP, PM10, PM2.5 samplers in the three manual measuring stations are under normal operation and regular maintenance operations. As of the end of December 109, a total of 24 regular maintenance tasks have been carried out, and no temporary failures have occurred and additional maintenance is required. Under the circumstances, multi-point calibration and maintenance are performed on a quarterly basis. In 109, the average measured value of TSP from January to December was 29μg/m3 at manual stations, a decrease of 3% from the average of the same period in the previous three years. The average measured value of PM101 from December to December is 22μg/m3, which is the same as the average for the same period in the previous three years. The average measured value of PM2.5 from January to December is 10μg/m3, which is 9% lower than the average of the same period in the previous three years. The amount of dust falling in 109 was not much different from that in 108 years. The average amount of dust from January to December in 109 was 3.5 (metric tons/square kilometer/month) in compliance with regulatory standards.
2. Operation and maintenance of automatic measuring station and monitoring results
The plan for this year requires regular maintenance twice a month. As of the end of December 109, the team has carried out 24 regular maintenance work on the monitoring equipment of the Fenglin station, and carried out annual maintenance and calibration of the automatic station on a quarterly basis. During the execution of this plan, the data availability rate of Fenglin Station from January to December reached an average of over 85%, and the monthly sampling data of the automatic station was submitted as scheduled. From January to December of 109, the monitoring items of SO2, NO2, CO, O3 at Fenglin station are not much different from previous years. In addition, the average measured value of PM10 at Fenglin station from January to December 109 is 29μg. /m3 (No data in January due to instrument failure), a decrease of 9% from the average of the previous three years.
In addition, the Fenglin automatic station building is old and leaking in many places, which has caused many water accumulations in the station building to affect the stability of the monitoring instrument. In September 109, air-conditioning was purchased and the station building reinforcement project was implemented to maintain the normal operation of the Fenglin station. .
3. Local characteristic control effectiveness and results PM10 and PM2.5 related control or research work
The average mass concentrations of PM10, PM2.5 and PM2.5-10 measured at designated stations from January to October 2020 without distinguishing the influence of airflow sources are 19.4, 8.0 and 11.4μg/m3; respectively; under the influence of the northeast monsoon 20.5, 8.5, and 12.0 μg/m3; 21.3, 9.4, and 11.9 μg/m3 under the influence of high pressure reflux; 16.6, 6.2, and 10.4 μg/m3 under the influence of Pacific high pressure; and 18.0, 7.1, and 18.0 μg/m3 under the influence of southwest airflow 10.9μg/m3; 25.6, 11.7, and 13.9 μg/m3 under the influence of mainland China. The airflow originates from the influence of mainland China. The mass concentration of PM10, PM2.5 and PM2.5-10 particles collected under the influence of mainland China is higher than other airflow sources , But its PM2.5 mass concentration is only 11.7μg/m3, which is lower than the annual average air quality standard of 15μg/m3 (only 78% of the annual average standard), indicating that the air quality in Hualien from January to October 2020 was polluted by air imported from abroad The impact of objects is not significant.
(3) Green beautification and air quality purification area
In order to continue the pollution purification work, this plan will assist the Hualien County Environmental Protection Bureau to continue to promote the inspection and counseling of the air quality purification area this year.
