臺灣博碩士論文加值系統

本論文目的係建立自動採樣與分析方法，自動化P＆T/GC/MS之檢測系統可同時自動分析84種的VOCs，並作定性定量的工作。此系統檢量線之RSDRRF 值為6.2％±4.1％；精密度為2.5％±1.4％；回收率方面為104.3％±14.3％；MDL為0.45±0.29ppb。本研究另外建立SPME/GC/FID，其針對水中之IPA、Ａcetone與DMS。其檢量線之平均RSDRRF值為15.8％；平均精密度為15.0％；回收率方面平均值為103.9％；平均之MDL為7.9ppb。
在實測方面，針對園區周遭環境進行佈點採樣，並首次使用自動VOCs採樣器於園區汙水廠進出流口進行24小時連續採樣，發現園區廠商排放廢水在時間上並無太大的變化趨勢，反倒是污水處理廠的處理結果有雙波峰趨勢存在；而針對污水處理廠內各單元分析水中與上部空氣中VOCs含量的關係，五月三日當日污水處理廠進水量約為125940CMD，放流水量約為88978CMD，因此進流水中Acetone估計約為1310.2Kg/Day、IPA估計為133Kg/Day、DMS估計約14Kg/Day，放流水中Acetone估計約為18.0Kg/Day、DMS估計約0.9Kg/Day、IPA方面並無測到。由以上數據可大致推算出園區污水處理廠對於這三種主要VOCs的處理效率約為93.6％（DMS）∼100％（IPA）；最後針對園區周界進行佈點採樣，在部分雨水放流口與污水處理廠外排放管道皆測有VOCs的存在，其中Acetone在1.15∼160ppb之間，而DMS在7.3∼89.5ppb範圍內。

The major objective in this study is to establish an automatic method of sampling and analysis, Automatic P&T/GC/MS system can analyze 84 kinds of VOCs (volatile organic compounds) in water simultaneously and automatically, and VOCs are qualitated and quantitated easily. RSDRRF of this system is about 6.2±4.1%; The precise of this system is 2.5±1.4%; Recovery is around 104.3±14.3％; MDL of all compounds is 0.45±0.29ppb. However for polar compounds, P&T shows poor linearity and precision, so SPME/GC/FID has been established for three polar compounds, IPA、Acetone and DMS. In QA/QC experiment, the average RSDRRF is 15.8%; the average precise is 15.0%; the average recovery is 103.9%; the average MDL is 7.9ppb.
In practice, the samplings have been proceeded in the vicinity of Science Park, and the VOCs autosampler has been used first time in the wastewater treatment plant to sample the effluent of the Hi-tech industries for 24 hours continuously. There is a trend that the emission of the wastewater of Science Park factory is constant but the water treated by wastewater treatment plant has been found a dual peak; the sampling for the wastewater and its upper air of every unit in the wastewater treatment plant was performed in order to realize the relationship of the VOCs concentration of wastewater and its upper air. On May 3, the wastewater volume which entered the wastewater treatment plant is about 125940CMD, and the outflow of wastewater treatment plant is around 88978CMD. Therefore, the estimated quantity of VOCs contains Acetone (1310.2Kg/Day)、 IPA (133Kg/Day)、 DMS (14Kg/Day) in inflow, and Acetone (1310.2Kg/Day)、 DMS (14Kg/Day) in outflow. IPA has not been measured here. According to the data above, the effect of treatment of wastewater treatment plant for these three compounds is about 93.6（DMS）∼100％（IPA）.
Finally, during the sampling in the vicinity of Science Park, VOCs was found in some of rain ditches and the channel of the outflow of wastewater treatment plant, in which the concentration of Acetone is between 1.15~160ppb, and the concentration of DMS is in the range of 7.3~89.5ppb.
