Abstract

The invention provides a desorption, regeneration and activation process for an adsorbent. The process comprises the following steps: (1) extracting water in an adsorbent tank through a vacuum pump; 2) starting a circulating fan and a reheater to remove residual water in an adsorbent bed layer; 3) controlling the temperature of the reheater to be 200-750 DEG C, heating the adsorbent bed layer to 300-550 DEG C, keeping the temperature for 0.5-8 hours, and starting an exhaust gas and fire exhaust tail gas treatment device; 4) closing the circulating fan, and introducing mixed gas into the adsorbent in the adsorbent tank for activation; and 5) cooling the adsorbent to a specified temperature to obtain a regenerated adsorbent. The desorption, regeneration and activation process of the adsorbent can realize online in-situ desorption, regeneration and activation of the adsorbent used for adsorbing organic matters in water, and has a good desorption regeneration effect, so the adsorbent can be used for a long time, and enterprise cost is saved.

Description

technical field [0001] The invention relates to a process for desorption, regeneration and activation of an adsorbent that absorbs organic matter in a water body, in particular to a process for desorption, regeneration and activation of an adsorbent and a system thereof. Background technique [0002] At present, the process of adsorbing organic matter with disposable adsorbents (such as activated carbon, activated coke, zeolite, etc.) is widely used in the advanced treatment of tap water, domestic sewage and industrial sewage. After the adsorbent is saturated, it needs to be replaced with a new adsorbent material, and the adsorbent after adsorption is usually used as hazardous waste, which needs to be entrusted to a qualified hazardous waste disposal unit for disposal or entrusted to an enterprise with regeneration qualifications to regenerate and reuse it. A large amount of disposal costs, and the replacement and transportation are relatively cumbersome and difficult to ope...
