| dc.description.abstract | 本研究採用2016年6月至2018年4月共 22個月的操作數據為分析資料，將活性污泥槽之溶氧、pH值、溫度等基本因子監控在固定範圍內，將MLSS控制在11,500 mg/L左右，期間添加葡萄糖、尿素等營養源，調整F/M在0.04~0.05 kg COD/kg MLSS - day之間，並觀察活性污泥槽菌相變化，以瞭解不同因子的操作參數，對MBR透過水通量變化造成之影響，使旁流式MBR效能維持在最佳效率。
本研究結果顯示，旁流式MBR之COD去除效率可達到97.5%，且透過薄膜結垢因子之控制，能有效提升透過水通量增加36%，同時讓廠內廢水系統維護費用單價減少45%；維護性線上藥洗能恢復MBR透過水通量9~22%不等，恢復性離線清洗完成之膜管，迴流通量均能恢復10~25%不等，同時也能提升19~20%之透過水通量。 | zh_TW |
| dc.description.abstract | In this study, operational data from June 2016 to April 2018 for a total of 22 months were used to monitor the basic factors such as dissolved oxygen, pH, and temperature in the activated sludge tank within a fixed range, The MLSS was controlled at 11,500 mg/L, during which glucose, urea and other nutrients were added. F/M was adjusted between 0.04~0.05 kg COD/kg MLSS-day. Changes of activated sludge tank phase was observed to understand the operating parameters of different factors’impact on the MBR through the water flux variations to maintain the optimum effectiveness of the side-by-side MBR. The results of this study show that the COD removal efficiency of side-stream MBR can reach 97.5%, and through the control of the membrane fouling factors, the permeate flux can be effectively increased by 36%, while the unit cost for the maintenance of the wastewater system in the plant can be reduced by 45%. The maintenance of online chemical wash can restore the MBR through 9~22% of the water flux, and the membranes recovered from the offline cleaning can recover 10~25% of the flux, and can also increase 19~20% of the flux. | en_US |
