This plan mainly executed the maintenance service of Tainan Air Quality Monitoring Display System to make sure the equipments’ normal operation and the data quality y, it also collected the entire service log sheet and the improvement suggestions provided to the Tainan Environmental Protection Bureau (EPB) 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.
The achievement of this project is stated below:
First, Chencily Auto-Monitoring Station
(1)Monitoring Station’s operation and maintenance
Regular Maintenance included weekly maintenance (48 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 result shown in table 1, its correlation coefficient all above 0.995, the slope all between 0.9~1.1, the intercept was between ±2%F.S., conformed to the Quality Check of survey Air Monitoring Standard.
All the data acquisition rate of all analyzers was all above 85%, the meteorological equipments were above 85%.
(3)Quality Control Process
It was based on AQMP plan from November 17th of 2011 and appointed Professor Wu,Yi-Ling of National Chengkung University to carry on sites quality check including Chencily Auto-Monitoring Station, Rende Manual Station and Yongkang Manual Station. All related quality check results were revised and confirmed in the sites.
(4)Explanation of monitoring result
Chencily Auto-Monitoring Station showed 5 episode day (O3 counted for 5 episode days); Annan station showed 3 episode days (O3 counted for 1 episode days and PM10 counted for 2 episode days); Tainan station showed 2 episode days (O3 counted for 2 episode days) ; Sinying station showed 2 episode days (O3 counted for 2 episode days) ; Shanhua station showed 1 episode days (O3 counted for 1 episode days).
Second, Xiaosimeng information electronic monitoring system
(1)Regular line inspection and environment clean check
Various months’ inspection frequency was all above 4 times.
(2)Information electronic display renewal operation
This plan in the execution period did 410 times advertisements in which the EPB took 78 times all together.
Third, the manual monitoring station
There were following stations including EPB, Mingde Secondary School, Shiehchin
Primary School, Chongshan Secondary School, Anping Waste Water Factory, South Administration Office stations.
(1)Monitoring station operation maintenance
It had to conduct the first half and second half monthly regular service and maintenance job and on 10th in next month to submit the report and make sure all various equipments led to 100% properly.
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 (100/7/22~100/7/25, 100/10/3~100/10/6, 101/1/3~101/1/6, 101/4/3~101/4/9) showed in Table 2, each error was between ±5%, and the R value was bigger than 0.995. Every half year conducted primary standard calibration (100/7/21, 101/1/2) the R value was 0.9999. All the calibration result in this plan met the code requirement.
(3) Monitoring result
In this year TSP monitoring result from July 2011 to June 2012, were complied with the air quality standard 24 hourly value (250 μg/m3). All previous years (from 2004 to 2011) this city TSP monitoring result showed that consistent tendency, presented the winter was high and the summer was low.
In the dust fall quantity monitoring part, from July 2011 to June 2012, each manual station classified as the extremely slight pollution class. All previous years from 2004 to 2011 each station dust fall demonstrated that The measured values declining. However, in year 2012 from January to June’s dust fall were also somewhat low.
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 – 9.24% to 8.74%, meets the erroneous within 10% requirement.
