The invention discloses a preparation method of an acetic acid-activated sludge-based adsorbent. The specific steps are as follows: taking an appropriate amount of sludge and glacial acetic acid to obtain a homogeneous acetic acid-activated sludge slurry; drying the homogeneous acetic acid-activated sludge slurry to obtain dry sewage Sludge and pulverize, and screen out sludge particles with a particle diameter of 1-2mm; add an activator solution compounded with zinc chloride and sulfuric acid, and perform pyrolysis reaction under nitrogen atmosphere to obtain sludge pyrolysis residue; wash with distilled water after grinding ,dry. The invention has simple manufacturing process and convenient operation. It adopts wet sludge to be directly pyrolyzed without drying treatment. The pyrolysis temperature is low, which belongs to low-temperature pyrolysis. While reducing the sludge drying process, it saves a lot of energy and is more energy-saving and environmentally friendly. The sludge adsorbent is prepared by the chemical activation method of the compound activator, and the carbon-containing compounds in the sludge are condensed into non-volatile polycondensation carbon through dehydration, condensation, moistening and expansion of chemical agents, so as to obtain adsorption with a well-developed porous structure. agent.
