Abstract:	論文研究以綜合性工業區污水經MBR薄膜生物處理系統產水水質為研究對象。產水水質長期實驗檢測結果顯示，因MBR薄膜生物處理系統主要功能乃過濾篩除水中懸浮固體並藉此去除非溶解性化學需氧量但對溶解性化學需氧量平均去除率未達50%，另對污水中重金屬去除率亦呈現不穩定降除結果。為提升綜合性工業區MBR薄膜生物處理系統對化學需氧量、重金屬去除率，先執行MBR薄膜生物處理系統與同廠原傳統生物處理系統中近似處理流程化學需氧量及溶解性化學需氧量去除效率檢測比對，並鑑別出兩系統差異處理單元化學混凝膠凝加藥單元並推論具補強化學需氧量與重金屬去除率功能，另藉由實驗室瓶杯模擬實驗驗證假設，蒐集各階段運轉測試與實驗結果評估尋求改善方針，故冀望藉由MBR薄膜生物處理系統處理綜合性工業區污水，首先需針對納管廠商及進廠水質源頭管控減少造成膜管污堵物質及高濃度水質進廠絕對是MBR系統實廠正常運作關鍵因素。且絕無一套處理系統可對任何污染水質完全有效去除，研究結果顯示綜合性工業區MBR薄膜生物處理系統至少需搭配化學混凝膠凝加藥反應單元，另對進廠水質特性需再配置其它處理系統方能使MBR薄膜生物處理系統優點完全有效發揮。;The purpose of this paper study was to investigate the effluent of membrane bioreactors for treatment industrial park sewerage system. Long-term experimental results show that the main function of membrane bioreactors is to remove the suspended solids in the wastewater and by the way remove the insoluble chemical oxygen demand, but the average removal rate of dissolved chemical oxygen demand is less than 50% and the removal rate of heavy metals in sewage also showed unstable results. To enhance the industrial park sewerage system membrane bioreactors for chemical oxygen demand, heavy metal removal rate, the first implementation of membrane bioreactors and the traditional biological treatment system similar process of chemical oxygen demand and dissolved chemical oxygen removal efficiency detection and comparison, and to identify the two systems of different treatment unit chemical coagulation-flocculation dosing reaction unit with chemical oxygen demand and heavy metal removal rate function, and by the simulated Jar tests to verify the hypothesis, Collecting the whole operation test and experimental result evaluation to seek improvement policy. It is hoped that by membrane bioreactors to deal with industrial park sewerage system wastewater, the first need for the industrial park manufacturers pre-treatment processes and into the membrane bioreactors raw wastewater quality control to reduce the formation of membrane fouling substances and high concentrations of raw wastewater into the plant is absolutely the key factor of membrane bioreactors smooth operation. And no treatment system can be completely effective for any pollutions to remove from the raw wastewater, the results show that membrane bioreactors for treatment industrial park sewerage system at least with chemical coagulation-flocculation dosing reaction unit, and investigate the other into the plant wastewater characteristics need to configure other wastewater treatment unit with the membrane bioreactors can make the full advantage of processing function.
