Activated carbon as an adsorbent or an adsorbent made of kaolin, the purification method for treating mercury-containing waste water, said adsorbing mercury removal method. For example, if a domestic factory treats mercury-containing sewage, the process adopts static adsorption method (precipitation, post-adsorption). Sodium sulfide as precipitant agent, i.e., so that mercury ions precipitate mercury sulfide, calcium hydroxide while a pH adjusting agent to ferrous sulfate as a coagulant in sewage removing silt and other suspended impurities, activated carbon adsorption and leakage metallic mercury and mercury compounds. The treated discharged water can reach the discharge standard. The process flow is shown in the figure below.
