微生物混合包埋技術(Entrapped Mixed Microbial Cell，簡稱EMMC)處理技術比，一般生物處理污水技術有操作簡單、成本較低、佔地小、操作更有彈性及效率等優點。本研究主要為製作包埋式混合微生物擔體，建構反應槽處理化糞池出流水，瞭解EMMC 微生物處理的效果，以供未來實廠設計之參考。研究方法共分為四個階段，以瞭解不問鹼度物質添加與不問水力停留時問(hydraulic retention time，HRT)操作條件下，EMMC系統對處理化糞池出流水之適用性與實際應用之可行性。實驗結果顯示本系統對SS及濁度去除效率極佳，TCOD與DCOD去除率最高可達92%與74%。研究顯示，利門本系統處理改善化糞池出流水，具有進一步研究發展之潛力，本研究之結果亦可作為實廠應用之參考，並提供水回收再利用之另一替代方案。 Entrapped Mixed Microbial Cell (EMMC) technique shares many advantages than conventional bio-treatment of sewage such as effective to produce and establish, robust, efficient, and easy to operate and maintain. The main aim of this research p1an was to manufacture EMMC carrier. Beside, a lab scale EMMC reactor was also conducted to find the feasibility of its application on the treatment of septic tank effluent. Four stages of the experiments were carried out for the examination of system performance under different conditions of alkalinity addition and hydraulic retention time. The results showed that the EMMC system could remove SS effectively and the highest removal efficiencies of TCOD and DCOD were 92% and 74 %, respectively. The results obtained from this study indicated that the EMMC is a high potential technology for wastewater treatment and could be considered as an alternative of on-site treatment unit for the polishing of septic tank eff1uent.
