Abstract

The invention discloses a membrane adsorption assembly, a regenerable membrane adsorption reactor, a liquid treatment apparatus and method. The membrane adsorption assembly comprises a central tube and a membrane adsorption roll, the central tube is provided with a plurality of tube holes for water discharge, the membrane adsorption roll is sleeved on the central tube, the membrane adsorption rollcomprises at least one membrane adsorption layer, and each membrane adsorption layer sequentially comprises a filtering film, a conductive anode, an insulation partition net and a conductive cathodefrom inside to outside. The high-efficiency coupling of membrane separation, adsorption and electrochemical advanced oxidation is realized, and the land occupation area and maintenance cost is reduced; and the in-situ green regeneration of the conductive anode is realized, the use of chemical reagents is reduced, the cost is reduced, and the wide popularization and application is relatively conducive.

Description

technical field [0001] The invention belongs to the field of advanced wastewater treatment, and in particular relates to a membrane adsorption component, a regenerable membrane adsorption reactor, a liquid treatment device and a method. Background technique [0002] With the development of industry, the discharge of industrial wastewater in my country has remained high in recent years. At the same time, due to different industries, the quality of wastewater is complex and changeable. However, the conventional treatment technology has certain limitations and cannot completely remove the pollutants in the water. Therefore, the residual refractory organic matter in the drainage not only brings various problems to the receiving water body, but also affects the living organisms. The cumulative effect of these pollutants poses a great health threat to organisms and humans. It can be seen that the advanced treatment of industrial wastewater is essential, and the high-efficiency in...
