    Abstract: 台灣由於地狹人稠,導致河川污染問題日益嚴重,近年,為了提升環境品質,政府積極推動興建水資源回收中心處理民生污水。
    In Taiwan, most of rivers were contaminated due to the dense population. Our government attributes a lot of effort to build sewage wastewater treatment plants in order to improve the environment quality. High moisture content and difficulty in dewatering are the main characteristics of wasted activated sludge generated from sewage treatment plant. Moreover, limitation in sludge reuse and disposal makes developing sludge reduction and final disposal technologies the important topics in 21st century.
    To enhance the efficiency of sludge anaerobic digestion and biogas generation, two different pretreatment methods, namely (1) advanced oxidation process with addition of persulfate only or with ferrous ion, and (2) heating, were explored in this study. The removal efficiency of Total Solids (TS) and Volatile Solid (VS) with various dosages of persulfate and ferrous chloride were conducted.
    The results show the TS decreases with pretreatment, while the change in VS is not significant. Since the pretreatment processes oxidize the easily oxidizable organic materials instead of the refractory organic material, no enhancement of the overall TS and VS reduction after anaerobic digestion was observed with the pretreated sludge.
