    Abstract: 在一般中型以上民生污水廠污泥處理流程,通常包括污泥濃縮、厭氧消化、及脫水單元,本研究嘗試將前向滲透技術(FO)結合厭氧消化程序,取代傳統的濃縮、消化程序,藉此降低污泥處理程序之用地面積及提高污泥厭氧消化效率。
    The sludge treatment and disposal process in wastewater treatment plant includes sludge concentration, anaerobic digestion and dewatering. This study investigates the feasibility of replacing traditional sludge concentration and digestion with the combination of forward osmosis technology and anaerobic digester in the hope of reducing area of treatment facility and improving anaerobic digestion efficiency.
    By utilizing a small-sized module which combined FO membrane and anaerobic digestion tank, the study used sodium chloride to prepare draw solution with concentration similar to seawater and sludge from full-scale plant to feed the anaerobic digester. The membrane flux, sludge digestion efficiency and the effect of reverse salt on forward osmosis anaerobic membrane bioreactor (FO-AMBR) were observed.
    The experimental results indicated that the decreasing flux is caused by concentrative external concentration polarization. The pH, ORP and removal efficiency of anaerobic digester are influenced by organic loading rate. Based on mass balance of suspended solids (SS) in and out of the digester, average removal efficiency of suspended solids (SS) is about 17.5% with the values calculated daily and is 19% obtaining from the accumulative values throughout the experimental run. In addition, the result of conductivity inhibition experiment shows that sludge after domestication is able to adapt in salted environment by slowly domesticated.
