NOVELTY - Treating sewage comprises using treatment agent for adsorbing and degrading the leachate, separating the treatment agent, where the treatment agent includes porous carrier and a microbial agent adsorbed on the porous carrier, and the porous carrier is rare earth- titanium dioxide/diatomite/graphene composite aerogel microspheres, and rare earth includes lanthanum, samarium or cerium, and microbial inoculums includes mixed inoculum including Aspergillus sojae, white rot fungus, and jelly-shaped Bacillus. USE - The method is useful for treating sewage. ADVANTAGE - The method: has excellent treatment effect on the leachate; reaches the COD removal rate more than 95%, removal rate of ammonia-nitrogen is over 93%, and removal rate of BOD5 is over 86%; and reaches chroma removal rate to more than 65%.
