Abstract: Taking a medical waste incineration treatment project in Qingdao as an example， the technological process and design parameters were introduced in detail. The process includes advanced automatic feeding system， rotary kiln incineration system， exhaust-heat utilization system and flue gas treatment system， which can realize the harmless and reductive treatment of medical waste and with a good operation effect. The combination of SNCR denitration， quench tower， dry deacidification， bag dedusting， wet deacidification， wet electric dedusting and SCR denitration were adopt in the flue gas treatment system， so that the flue gas discharge could up to the standard under the condition of the flue gas emission standard upgrading.
