This plan mainly executed the maintenance service of Tainan Air Quality Monitoring Display System to make sure the normal operation and the data quality for equipment, it also collected the log sheet of entire service and the improved suggestions provided to the Tainan Environmental Protection Bureau (EPB) to realize the service conditions. Further to this, it offered revised standard of operational procedure and the maintenance test to guarantee the maintenance quality and met the inspection monitoring station assessment criteria from Central Environmental Administration Bureau. Plan of Cheng：From 5th July 2013 to 4th July 2014. The achievement of this project is stated below: First, Automatic Station (1)Monitoring Station’s operation and maintenance Regular Maintenance included weekly maintenance (52 times), monthly maintenance (12 times), and quarterly maintenance (4 times), and half-yearly maintenance (2 times) and yearly maintenance (1 time), all works based on this plan schedule to carry on and all equipments in the execution period led to achieve 100% properly.Quarterly maintenance in analyzers’ of multi-spot calibration, its correlation coefficient all above 0.995, the slope all between 0.88~1.12, the intercept was between ±2%F.S., conformed to the Quality Check of survey Air Monitoring Standard. (2)Data Management All the data acquisition rate of all analyzers were all above 85%, the meteorological equipments were above 85%. (3)Explanation of monitoring result 1.PSI for bad days: From July 2013 to June 2014, Sinying station has had 15 bad days, Shanhua station has had 10 bad days, Annan station has had 19 bad days and Tainan station has had 12 bad days. During the time period, ozone events were occurred for 1 days; in a addition, the aerosol event of occurred for 1 day. 2. Air Quality Standard: Comparing with PSI index and Air Quality Standard in the ozone portion. Over the years, the PM10, Sinying station was beyond the frequency range from 5.46% ~12.05%, Shanhua station range from 0.82% ~4.93%, Tainan station range from 0.82% ~4.93%, Annan station range from 0.27% ~7.18%. The O3, Sinying station was beyond the frequency range from 16.99% ~32.26%, Shanhua station range from 16.99% ~37.26%, Tainan station range from 32.33% ~47.40%, Annan station range from 31.23% ~44.66%. Second, Xiaosimeng information electronic monitoring system (1)Regular line inspection and environmental clean Every inspection is above 1 times per 1 month. (2)Update of display board This plan in the execution period with 334 times advertisements was including the EPB took 69 times. Third, the manual monitoring station (1)Operation and maintenance in monitoring station It had to conduct the regular service and maintenance in every beginning of the month and end of the month. For the next month, submitting the report and make sure all various equipments led to 100% properly ration before 10th. (2)Calibration Process For single point check before and after sampling, the flow should be between 40 to 60 CFM and the error was between ±7%. For quarterly multi-spot calibration (2013/7.10., 2014/01.10), each error was between ±5%, and the R value was bigger than 0.995. Every half year conducted primary standard calibration (2013/7/4, 2013/1/3) the R value was 0.9999. All the calibration result in this plan met the regulation. (3) Monitoring result In this year, TSP monitoring result from July 2013 to June 2014, were complied with the air quality standard 24 hourly value (250 μg/m3). All previous years from 2008 to June 2014 were this city TSP monitoring result showed that consistent tendency, presented the winter was high and the summer was low. Over the years, annual geometric average value has not exceeded the annual geometric average of air quality standard which is 130 μg/m3. In the dust fall of quantity monitoring part from July 2013 to June 2014, each manual station classified as the extremely slight pollution class. All previous years which are from 2010 to 2014 for each station and dust fall demonstrated that reducing the measured values. However, in year 2013 from January to June’s dust fall were also lower slighly. For average value of PM10 station, Baihe middle school is the highest average value which is 197 μg/m3, and Syuejia elementary school is the lowest value which is 10 μg/m3. For average value of PM2.5 station, Shjhs sewage station is the highest average value which is 74 μg/m3, and Baihe clinics station is the lowest average value which is 3 μg/m3. TSP monitoring value of each component which the range in the analysis of chlorine in salt content is between 0.46 ~ 6.22 μg/m3, the range of nitrate content is between 1.01 ~ 19.01 μg/m3, the range of sulphate content is between 2.19 ~ 38.72 μg/m3, and the range of lead level is between 0.001 to 0.199 μg/m3. For measured values over the years, the tendency showed the higher value in winter and lower value in summer. In PM2.5 and PM10 ratios, the range of the manual stations is between 0.09 to 0.91, and the range of the automatic stations is between 0.13 to 0.69. Both of values has slight difference. In addition, for the overall average, the manual station is 0.68 and automatic station is 0.50, so the manual station is relatively higher which is considering the difference between manual and automatic station regarding analysis theory. Thus, the comparison is only for the reference. (4) Accuracy test This plan completed 12 manual stations for the accuracy quarterly tests in which all the present stage did 12 times parallel sampling work and the whole error percentage was between 1.06% to 9.01%, meets the erroneous within 10% requirement.
