本論文探討改變粒徑大小對於石灰石溶解量在間歇式加壓流體化石灰石床系統中之影響，並探討石灰石溶解量表示方式之差異。結果顯示較小的粒徑能夠提供較多的石灰石溶解量，且中和酸度的能力較強。高鐵離子濃度會因為沉澱物包覆於石灰石表面，使溶解量降低。低原水進流流量提供較長停留時間，對於石灰石溶解量較有幫助。比較以火焰式原子吸收光譜儀所測得之鈣離子濃度、鹼度變化量、出流水pH值與鹼度計算之碳酸系統濃度( )及利用電荷平衡所計算得之碳酸氫根濃度表示石灰石溶解量，其中以電荷平衡計算表示之石灰石溶解量值，較能顯示實際值。 The objective of this thesis is to estimate limestone dissolution in fluidized pulsed limestone bed system (FPLB system) that is affected by the limestone particle size. Four methods indicating limestone dissolution were also investigated. From the results, better limestone dissolution ability and acid water neutralization capacity were seem in FPLB of smaller particle size. Armoring on limestone particle was seen in the condition of higher ferric concentration and hence lower limestone dissolution rate was shown. Due to lower inflow rate, more limestone dissolved in the condition of long retention time. The method depicting the concentration of limestone dissolution is better represented through the way of charge balance due to the similarity performance of calcium concentration measured by atomic absorption instrument.
