The invention provides a method for efficiently and circularly treating excess sludge. The method specifically comprises the following steps: S01, sludge conditioning; s02, dewatering and drying the sludge; s03, pyrolyzing the sludge; s04, separation of sludge pyrolysis gas; and S05, preparing the modified sludge biochar. According to the method, the biochar and the pyrolysis gas after sludge treatment can be recycled, meanwhile, the sludge dewatering performance is improved, and the release risk of heavy metal on the surface of the biochar is effectively avoided, so that maximum and most sufficient utilization of sludge recycling is realized, the cost is effectively reduced, and the sludge treatment efficiency and effect are improved.

The invention relates to composite charcoal for adsorbing carbon dioxide, which is prepared by mixing dewatered sludge and chicken manure according to the dry weight ratio of sludge to chicken manure of 1: (2.5-3.5) as raw materials through circulating pyrolysis, and the circulating pyrolysis comprises the following steps: putting the mixed raw materials into circulating pyrolysis equipment; and pyrolysis steam is refluxed into the pyrolysis zone for circular treatment while pyrolysis is carried out. According to the method, sludge and chicken manure are mixed, on the basis of traditional co-pyrolysis, reflux pyrolysis steam action and biochar are performed, so that surface functional groups of the prepared composite biochar are greatly increased, the prepared biochar is mainly subjected to chemical adsorption, the CO2 adsorption performance is remarkably improved, and the adsorption capacity reaches 96.16 mg/g.
