▎ 摘　　要

NOVELTY - Treating mercury containing sewage involves adding a composite flocculant to the mercury-containing sewage, adsorbing the treated mercury-containing sewage with a special adsorbent and treating with porous activated carbon, where the composite flocculant includes 5-10 pts. wt. aluminum chloride, 3-7 pts. wt. poria cocos, 2-5 pts. wt. diatomite and 4-6 pts. wt. ammonium citrate and the special adsorbent includes 10-20 pts. wt. quartz sand with sulfur-containing functional groups, 3-5 pts. wt. zeolite and 5-7 pts. wt. carbon fiber with a diameter of 3-5 nm. USE - Method for treating mercury containing sewage. ADVANTAGE - The method can efficiently treat organic, inorganic and residual mercury in the sewage so that the method is worthy of widespread promotion and application.
