通过水热法研究 O2、H2 O2降解医疗垃圾焚烧飞灰中二恶英的规律。研究结果表明，2MPa 氧气和8．36mL 双氧水，其他条件相同时，飞灰中二恶英降解效率基本相同；50℃和通氧条件下，飞灰中二恶英降解效率最高84．2％；在氧化剂存在时，PCDFs 的降解效率高于 PCDDs 的降解效率；除 T4CDD-2378的降解效率低于60％外，其余16种有毒二恶英降解效率均高于70％，其中 T4CDF-2378在200℃和通氧条件下降解效率最高为94．1％；水热法降解二恶英过程中存在高代二恶英的脱氯反应。

The properties of degradation of dioxins in medical incineration fly ash were researched by oxygen (O2 ) and hydrogen peroxide(H2 O2 ) oxidizing.There was no difference on the degradation of dioxins in fly ash when the system was added to 2 MPa oxygen or 8.36 mL of hydrogen peroxide.With 250℃ and 2MPa oxygen, maximum degradation efficiency was 84.2%.Degradation efficiency of PCDFs was much more than PCDDs ’, when oxidant existed.Under four different conditions,degradation efficiency of T4CDD-2378 was the lowest, and the other efficiency were higher than 70%.The maximum degradation efficiency of T4CDF-2378 was 94.1% and the temperature was 200℃ in 2MPa oxygen atmosphere.There had dechlorination reaction in degradation of dioxins using hydrothermal .
