Description

technical field [0001] The invention relates to the field of interface polymerization technology and membrane performance testing, and more specifically relates to a device for interface polymerization technology and membrane performance testing and an operating method thereof. Background technique [0002] In recent years, with the development of industry and economy, many discharged water containing toxic substances that are difficult to biodegrade have continuously entered the environment, causing great harm to industrial and agricultural production, people's lives and human health. In order to solve this problem, a Membrane separation technology based on the principle of physical separation and purification has developed rapidly in recent years. Interfacial polymerization can prepare a nano-scale ultra-thin polymer layer, which makes this type of membrane have high selectivity and permeability under low pressure, so it has attracted much attention and attention in the fi...
