摘　　要：废弃乳化液是机械加工行业产生的油水混合废弃物,由于其对环境或人体健康造成有害影响,需要按照危险废物进行管理和处理处置。以四川省某危废处理厂废乳化液处理生产线为例,针对其占地面积大、能耗高和处理效率低的问题,提出一种工艺系统优化设计方案。通过对废乳化液物化处理系统中破乳、气浮装置的优化设计,达到简化工艺流程、降低能源消耗的目的。此外,采用优化工艺系统,废乳化液物化处理工段出水水质得到了进一步提升。Waste emulsion is the oil-water mixture waste produced by machining industry,and it is needed to be managed and treated as the hazardous waste because of its harmful effect on environment and human health.Taking the example of the waste emulsion treatment production line of a hazardous waste treatment plant in Sichuan,to solve the problems of large equipment floor area,high energy consumption and low treatment efficiency,an optimized scheme of physical-chemical treatment process of waste emulsion is proposed.By optimizing the demulsification and air flotation device in the physical-chemical treatment system of waste emulsion,the process flow is simplified and the energy consumption is reduced.The effluent quality of waste emulsion treatment section is further improved after using the optimized process system.
