Description

technical field [0001] The invention belongs to the fields of energy storage devices, ion adsorption devices and water treatment desalination, and in particular relates to a high-efficiency liquid flow type membrane capacitance desalination device. Background technique [0002] Due to the presence of Ca in industrial or domestic tap water 2+ , Mg 2+ and some anions such as HCO 3 - , if it cannot be effectively removed, it is easy to scale on the pipe or furnace body and block the pipe. If it enters the human body, it is easy to form stones and cause other health problems; a large amount of industrial wastewater containing harmful ions discharged from industries such as metallurgy, electroplating, chemical industry and even nuclear power has also caused damage to the water environment and harm to human health; in addition, biopharmaceuticals, micro Industries such as electronics manufacturing also require large quantities of high-purity deionized water. Therefore, deioni...
