Feasibility of supercritical water treatment on co-detoxification of PVC and medical waste incinerator fly ash
超临界水无害化共处理PVC和医疗垃圾焚烧飞灰的可行性探讨

This study investigated the feasibility of supercritical water(SCW) treatment on synchronous detoxification of medical waste(MW) incinerator fly ash and PVC.The main merit was that hydrocloric acid could be formed during dechlorination of PVC in supercritical water which was effective for heavy metals extraction. SCW could destroy ash particles,thus improved heavy metals extraction efficiency and velocity.However,SCW also had the effect of fixing metal ions into the ash matrix,hence over time or extremely h...
