Abstract

The invention belongs to the field of solid waste, and particularly relates to an activated carbon reactivation method, titanium dioxide particles on the surface of modified nano glue and pollutants in waste activated carbon are utilized to form contact surface connection, a sodium sulfate electrolysis system is formed through an electrolysis device, and a low-concentration low-current degradation system is achieved. At the moment, titanium dioxide and an electrolysis system form a photoelectric synergistic effect, a good degradation effect is achieved, meanwhile, a low-current and low-concentration environment can ensure the stability of the nano glue, and the contact stability of titanium dioxide and pollutants can be kept.

Description

technical field [0001] The invention belongs to the field of solid waste, and in particular relates to a method for reviving activated carbon. Background technique [0002] Activated carbon has a huge specific surface area, high porosity and good physical and chemical properties. Its internal pore structure is developed and its excellent adsorption performance on molecules ensures its wide application in water treatment and other environmental protection fields. At present, activated carbon is mainly used to treat domestic wastewater, organic wastewater, and advanced treatment of drinking water. However, the adsorption capacity of activated carbon based on the adsorption performance in its own pore structure is very prone to adsorption saturation, and the adsorption performance of activated carbon after adsorption saturation is sharp. The replacement of new activated carbon will lead to an increase in treatment costs, and the waste of saturated activated carbon will easily c...
