摘要

為了有效控制並降低空氣中污染物濃度的增加，近年來環保署持
續推動著總量管制的策略，來管制固定污染源之排放並針對不同之污
染防制區內制定了不同空氣污染物之容許增量限值。本研究利用
CALPUFF 擴散模式來測試空氣污染物容許增量限值，並透過模擬之
結果給予未來在容許增量限值相關制度上之參考。本研究分成3 個CASE 來測試空氣污染物之容許增量限值，CASE1 以一定規模之排放量來測試，模擬結果顯示法規所制定之ㄧ定規模排放量硫氧化物60 公噸、氮氧化物40 公噸、懸浮微粒15 公噸大致上吻合。CASE2 與CASE3 以硫氧化物與氮氧化物總和排放量來模擬衍生性懸浮微粒量，並篩選以日平均最大濃度增量日為案例日，來作一個時空上之分析與討論，模擬結果顯示衍生性懸浮微粒濃度增量於污染源高度為25 公尺，硫氧化物與氮氧化物總和為1000 公噸時，可佔法規值11%~18%，並有著跨區輸送的現象存在。此模擬結果也顯示出若與原生性懸浮微粒量合計，其污染程度可謂更是嚴重，此結果也可反應於在空氣品質模式模擬規範草案上，未明確規範原生性懸浮微粒排放量的部份。

In order to control and reduce the pollutant increments in the air, EPA continued to impel the total quantity control strategy to control the emission of stationary pollution sources in the recent years. Different air pollution control
zones had different air pollution allowable pollutant increase limits(APIL). In the study, APIL would be tested with CALPUFF model, and the result of simulations would be the reference for establishing criteria of APIL in the
future. This research was divided into three cases to test APIL. In CASE1, the pollutant emissions reached a certain scale, and the result of simulations was consistent with the law standard. CASE2 and CASE3 simulated the increment
of secondary particulate matter concentration by the sum of sulfur oxides and nitrogen oxides, and took the date which daily average concentration increment was greatest as case date to discuss and analyze. The result of simulations
showed that the increment of secondary particulate matter could be 11~18% of the law standard when the stack height was twenty-five meters and sum of sulfur oxides and nitrogen oxides were one thousand tons and the phenomenon
of traverse regions transportation existed. If the quantities of primary and secondary particulate matter were considered at the same time, the pollution condition would be worse. This result would also reflect the defect not
formulating the amount of the primary particulate matter in the air quality modeling and simulation draft.
