| 摘 要： | 膜生物反应器(MBR)处理船舶含油废水在工程中得到了广泛的应用,为了研究膜生物反应器运行参数对处理船舶含油餐饮废水的影响,通过生产油脂产生的废水模拟船舶含油废水的水质特性,搭建小型膜生物反应器陆上试验系统,用光谱仪等仪器测量化学需氧量(COD)、生化需氧量(BOD)及氨氮等参数。研究膜生物反应器的水力停留时间(HRT)、COD和BOD及氨氮、膜压力、污泥浓度等指标之间的关系。系统稳定运行了70天。研究结果表明:膜生物反应器对油脂废水中COD、油、总碳(TOC)和BOD的去除率达80%以上,对氨氮的去除率达50%以上;油对膜的污染有较大影响。

| Abstract: | Membrane bioreactor(MBR) has been widely applied to the treatment of ship's oily wastewater. To study the operating parameters of MBR on the treatment of oily wastewater produced by onboard restaurants, wastewater is first produced from axunge which simulates the water characteristics of ship's oily wastewater, and a small shore-based MBR system is subsequently founded.Chemical Oxygen Demand(COD), Biochemical Oxygen Demand(BOD), ammonia nitrogen are tested with the measuring device like spectroscope.The relationship between the Hydraulic Retention Time(HRT) s, COD, BOD, ammonia nitrogen, membrane pressure and sludge concentration during the 70 days operation of the MBR system is also studied, which shows that the MBR could remove the COD, oil, TOC, BOD by over 80% and ammonia nitrogen by over 50% in oily wastewater.Furthermore, the research also indicates that the oil greatly affects the membrane fouling. |
