Description

technical field [0001] The invention relates to an electrolysis device, in particular to an electrolysis device with membrane filtration function. Background technique [0002] In recent years, electrochemical treatment is one of the more active water treatment technologies in physical and chemical treatment technology. It mainly uses the principle of primary battery or electrolysis to treat wastewater. Currently, there are various types of electrolysis devices and micro-electrolysis devices, which have been applied to the treatment of domestic wastewater, industrial wastewater, and the like. However, some problems have been exposed during the operation of the existing electrolysis device. First, the electrode consumption is large, and the electrode material pollutes the water body; The energy consumption is large; the third is that after electrolysis, the solid-liquid separation effect is not ideal, and a second solid-liquid separation is required, and the process flow is ...
