The membrane distillation technology used in this paper is a new type of wastewater treatment technology, which is now mostly used in seawater desalination and wastewater treatment. The traditional oily wastewater treatment methods have problems such as large energy consumption and low removal rate. It is proposed to use vacuum membrane distillation technology to use a large amount of waste heat in wastewater as the driving force for mass transfer to treat oily wastewater, which not only saves energy, but also effectively counteracts the problem. The solid particles, hydrocarbons and other pollutants contained in the wastewater are intercepted, so that the treated water quality reaches a certain degree of purity and meets the discharge standards. In this paper, the membrane microporous membrane used in the process of membrane distillation is targeted at the problem of membrane pollution Improved to achieve the purpose of reducing costs and increasing membrane life.
