Abstract

The invention discloses a spent activated carbon regeneration method, which comprises the steps of storage, pretreatment, heating power preparation, roasting, aftertreatment and packaging as well as preheating and the like. The optimal activated carbon regeneration processing steps are screened out through a large number of experiments. According to the regenerative activated carbon produced by the regeneration method, the adsorptive property of the regenerative activated carbon reaches 95 percent to 110 percent of original activated carbon, the intensity basically does not change, the regeneration rate can be kept above 90 percent and in a whole regeneration and activation process, biomass particle combustion furnace equipment is used, by combusting biomass fuel, sufficient heating power is provided for a high-temperature activation region in the middle of a tunnel kiln, so that the product quality of the regenerative activated carbon is facilitated, the raw material loss can be greatly reduced, and the economical and biological benefits are good. Meanwhile, the technology is scientific and reasonable, mature, safe and environment-friendly, and secondary pollution cannot be caused to the environment, the waste is turned into treasure, so resource waste and environment pollution can be reduced, and important economic value and social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of resource utilization, and in particular relates to a regeneration treatment method for waste activated carbon. Background technique [0002] Activated carbon has a highly developed pore structure and a suitable specific surface area, is non-toxic and tasteless, and has a strong adsorption capacity for colored molecules of organic substances. It is often used as an excellent adsorbent and is widely used in medicine, metallurgy, food, and chemical industry. , military and environmental protection and other fields. In recent years, with the improvement of people's social awareness of environmental protection, the demand for activated carbon in environmental protection is increasing, and it is widely used in urban water supply purification, harmful gas adsorption, drinking water purification and industrial wastewater advanced treatment. However, due to the high price of activated carbon and the shortage of p...
