As of December 31, 2018, the overall progress of the implementation of this project reached 100%. The summary of relevant work results is as follows:
I. Results of air pollution control in 2018
(1) Air quality maintenance and improvement results
In 2018, the city's air quality and good results statistics show that compared with the base year (2015-2017 average) improvement rate: ozone (hourly average) is 0.4%, ozone (8-hour average) is 0.7%, PM10 ( Annual average) is 2.7%, PM10 (daily average) is 2.1%, PM2.5 (manual annual average) is 4.7%, PM2.5 (24-hour average) is 4.5%, SO2 (annual average) is 8.0%, SO2 (hourly average) is 9.4%, SO2 (daily average) is 7.6%, NO2 (annual average) is 4.4%, NO2 (hourly average) is 5.7%, CO (hourly average) is 5.8%, CO (8 hour average) At 6.5%, only the PM2.5 project did not achieve the improvement goal, and the rest reached (1) the performance showed an annual concentration improvement rate of 5% or (2) the performance showed that the annual concentration met the target value of the air quality standard.
The average AQI for air quality indicators is 63, AQI≦50 (good) has a total of 136 stations (37.9%), and AQI>100 (bad) has a total of 38 stations (10.6%); in this year, from February to April due to the poor seasonal air quality (poor climate diffusion conditions), the proportion of good station days was less than 15%; in September, the northeast monsoon caused the impact of foreign pollutants, and the good proportion fell to 23~25%.
(2) Changes in air pollutant concentration
1. Suspended particles (PM10)
In this year, degree of 35.6 μg/m3 is 0.6 μg/m3 lower than that in 2017.
2. Fine aerosol (PM2.5)
In this year, manual measurement of 17.9 μg/m3 was 1.2 μg/m3 higher than that in 2017.
3. Sulfur dioxide (SO2)
In this year, statistical average of SO2 concentration is 2.01 ppb, which is the lowest in the calendar year, which is 0.33 ppb lower than that in 2017.
4. Nitrogen dioxide (NO2)
In this year, statistical average of NO2 concentration was 13.25 ppb, a decrease of 0.47 ppb in 2017.
5. Ozone (O3)
In this year, statistical average of O3 concentration was 29.21 ppb, which was 1.55 ppb lower than that in 2017.
6. Carbon monoxide (CO)
In this year, statistical average of CO concentration was 0.37 ppm, the same as that in 2017.
7. Non-methane hydrocarbons (NMHC)
In this year, statistical average of NMHC concentration of 0.11 ppm was the lowest in the calendar year, it lower 0.03 ppb than that in 2017 .
(3) Air quality improvement, pollution prevention target value achievement
In 2018, the city's air quality and good results statistics show that the AQI>100 station daily ratio is 10.6%, the AQI<50 station day ratio is 37.9%, and the PM2.5 annual manual average is 17.9 μg/m3. Except for the target value of quality improvement, the rest will reach the target value set this year.
(4) The achievement of the target value of the clean air action plan
The implementation results of the target value set evaluation method show that the PM2.5 improvement rate and concentration value are not up to the target of the air quality maintenance and improvement results in 2018; the local problem management performance is the removal of the mobile source two-stroke locomotive, phase one or two The elimination of diesel vehicles and the installation of third-phase diesel fuel filters and the improvement of fixed-source boilers have not met the target. The management of the policy of the Department as a medium-sized innovation is not a target for the whole country.
(5) The achievement of air pollutant reduction
In 2018, the total reduction was 658.74 metric tons. In terms of pollutants, the reduction of PM10 was 236.64 metric tons, followed by NOx reduction of 189.28 metric tons, followed by NMHC reduction of 156.79 metric tons, and PM2.5 reduction. Up to 68.07 metric tons, SOx is at least 7.97 metric tons.

3. Evacuation source
There are 1,654 constructions, with an average of 15.9 projects per square kilometer. The development of the project in the past three years is still dominated by other types of projects, with the highest proportion of increase, followed by road engineering and construction (RC) projects. In terms of the total amount of emissions in this city, this year, the municipal government continued to promote the green plan to activate idle state-owned land, and to tackle the environmental improvement project of the first Qianxi 20 plough for the left bank of the Qianqian River, the new construction of the baseball sports park and the surrounding landscape optimization project. The Kezi Lake Constructed Wetland Water Diversion Improvement Project, etc., at the same time, the Nanxun Sports Park, the windbreak forest greening, the parent-child beach, etc., created the Hsinchu City Waterfront Blue Ribbon, and activated the Nanxun Fishing Port Tourism Rest Area project, which is more consistent than the 106 years. 2% reached 87%, the management rate increased by 12% to 90%, and the reduction rate increased by 1% to 56%.
Third, the air pollution prevention plan management operations
