摘　　要：以平板陶瓷膜为核心过滤介质,以含乳化油废水为处理对象,以出水COD_(Cr)为指标,研究了进水COD_(Cr)、pH值、曝气等因素对处理效果的影响,考察了平板陶瓷膜处理含乳化油废水的可行性。结果表明:在进水COD_(Cr)为120 mg·L^(-1)、pH为9且曝气的条件下,平板陶瓷膜的处理效果最佳,其出水COD_(Cr)可降至57 mg·L^(-1)、去除率为52.5%。同时,曝气可以有效降低膜污染程度,延长平板陶瓷膜使用时间。[Background and purpose]The improvement in the degree of industrialization,the continuous development of machining,steel,minerals and other industries have led to increasing demand for emulsified oil in the industry.With the expanded application of emulsified oil,the environmental problems caused by wastewater discharge become more and more aggravated.Such wastewaters contain high concentration COD_(Cr),with complex composition and difficulty in degradation,which poses a threat to the ecological environment and human health.Conventional treatment processes,such as electrolysis,precipitation and flocculation,have encountered problems,such as low removal efficiency,high cost and secondary pollution.Ceramic membranes have strong anti-pollution performance,long cleaning cycle,easy maintenance and no need of chemical agents,thus being in line with the concept of environmental protection.Therefore,it has been widely used in the treatment of emulsified oil wastewater.In this study,the efficient interception of emulsified oil in wastewater by using flat ceramic membrane was realized,aiming to provide theoretical basis for the application of flat ceramic membrane in the treatment of wastewater containing emulsified oil.[Methods]The rationality of the experimental design was verified by analyzing the characteristics of the emulsified oil and the characterization properties of the flat ceramic membrane.The influences of influent COD_(Cr) concentration,pH value,aeration and other factors on the treatment effect of the flat ceramic membrane were explored.In order to obtain the optimal process conditions for treating wastewater containing emulsified oil,GPC was used to detect the emulsified oil,so that the molecular weight and distribution of the components were determined.SEM and EDS were used to characterize the ceramic membranes and observe their surface morphology.COD_(Cr) was determined according to HJ/T 399-2007 Determination of Water Chemical Oxygen Demand by Rapid digestion Spectrophotometry.In order to ensure the accu
