飞灰粒径对二恶英降解效率的影响

Effectof Fly Ash's Particle Size on Dioxins Degradation Efficiency

低温热脱氯工艺是垃圾焚烧炉飞灰中二恶英分解的一种常见技术,一方面可以实现对大部分二恶英同系物地高效脱除,但是另一方面也容易产生额外的二恶英。为了克服该技术的不足,进一步提高降解效率,本文将低温热脱氯工艺与TiO2/MoS2复合催化剂光催化降解技术相结合,研究在两者共同作用下,飞灰粒径对二恶英降解效率的影响。

Low temperature thermal dechlorination process was a common technique of decomposing dioxins from municipal solid waste incineration ash. This technique can efficiently remove most dioxin congeners, hut it was also easy to produce additional dioxin. In order to overcome the disadvantages of the technology and further improve the degradation efficiency of dioxin, techniques of low temperature thermal dechlorination process and molybdenum disulfide composite pillared by titanium the fly ash＇s particle dioxide photocatalytic degradation were combined. Under the interaction of these two techniques, how size effect on the decomposition efficiency of dioxins was studied.
