Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a membrane material for industrial wastewater treatment and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the advancement of global industrialization, a large amount of industrial wastewater and urban domestic sewage containing heavy metals have been discharged into the environment, posing a serious threat to the atmosphere, soil and water environment, especially human health. If it is dealt with, it will cause serious damage to the heart, kidney, liver and other vital organs of the human body. Therefore, seeking effective industrial wastewater treatment technology has become the focus of urgent attention in the industry. [0003] At present, the treatment methods for industrial wastewater containing heavy metals mainly include: chemical precipitation method, electrochemical method, adsorption me...
